II (“Khosla”) and Nextdoor, Inc. (“Nextdoor”). This Presentation does not constitute an offer, or a solicitation of an offer, to buy or sell any securities, investment or other specific product, or a solicitation of any vote or approval, nor shall there be any sale of securities, investment or other specific product in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. The information contained herein does not purport to be all-inclusive and none of Khosla, Nextdoor, Morgan Stanley & Co. LLC, and Evercore Group L.L.C. nor any of their respective subsidiaries, stockholders, affiliates, representatives, control persons, partners, members, managers, directors, officers, employees, advisers or agents make any representation or warranty, express or implied, as to the accuracy, completeness or reliability of the information contained in this Presentation.

In addition, this Presentation does not purport to be all-inclusive or to contain all of the information that may be required to make a full analysis of Khosla, Nextdoor or the Business Combination. The general explanations included in this Presentation cannot address, and are not intended to address, your specific investment objectives, financial situations or financial needs. Forward-Looking Statements Certain statements in this Presentation may be considered “forward-looking statements” within the meaning of the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995 with respect to the Business Combination. Forward-looking statements herein generally relate to future events or the future financial or operating performance of Khosla, Nextdoor or the combined company expected to result from the Business Combination (the “Combined Company”). For example, projections of future financial performance of Nextdoor and the Combined Company, the Combined Company’s business plan, other projections concerning key performance metrics, the proceeds of the Business Combination and the Combined Company’s expected cash runway, and the potential effects of the Business Combination on Khosla and the Combined Company, are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “ may,”“ should,”“ expect,”“ intend,”“ will,” “estimate,”“ anticipate,”“ believe,”“ predict,” “project,” “target,” “plan,” or “potentially” or the negatives of these terms or variations of them or similar terminology. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by Khosla, Nextdoor and its management, as the case may be, are inherently uncertain and subject to material change. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risk and uncertainties. Factors that may cause actual results to differ materially from current expectations include, but are not limited to, various factors beyond management’s control, including general economic conditions and other risks, uncertainties and factors set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in Khosla’s final prospectus relating to its initial public offering, dated March 23, 2021, other filings with the Securities and Exchange Commission (“SEC”), as well as factors associated with companies, such as Nextdoor, including anticipated trends, growth rates, and challenges in those businesses and in the markets in which they operate. Nothing in this Presentation should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements in this Presentation, which speak only as of the date they are made and are qualified in their entirety by reference to the cautionary statements herein. Nothing in this Presentation should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements in this Presentation, which speak only as of the date they are made and are qualified in their entirety by reference to the cautionary statements herein and the risk factors of Khosla and Nextdoor described above. Neither Khosla nor Nextdoor undertakes any duty to update these forward-looking statements. Use of Projections This Presentation contains projected financial information with respect to Nextdoor. Such projected financial information constitutes forward-looking information, is for illustrative purposes only and should not be relied upon as being predictive of future results. The assumptions and estimates underlying such financial forecast information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties that could cause actual results to differ materially from those contained in such prospective financial information, including without limitation, assumptions regarding Khosla’s and Nextdoor’s ability to consummate the Business Combination, the failure of which to materialize could cause actual results to differ materially from those contained in the prospective financial information. Khosla and Nextdoor caution that their assumptions may not materialize and that current economic conditions render such assumptions, although believed reasonable at the time they were made, subject to greater uncertainty. See the section above titled “Forward-Looking Statements”. The inclusion of financial forecast information in this Presentation should not be regarded as a representation by any person that the results reflected in such forecasts will be achieved. Neither Khosla’s nor Nextdoor’s independent auditors have audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation or any other purpose, and accordingly, none of such independent auditors has expressed any opinion or provided any other form of assurance with respect to such projections. Financial Information and Use of Non-GAAP Financial Measures The financial information contained in this Presentation has been taken from or prepared based on the historical financial statements of Nextdoor for the periods presented. An audit of these financial statements is in process. Accordingly, such financial information and data may not be included in, may be adjusted in or may be presented differently in any registration statement on Form S-4 to be filed with the SEC by Khosla in connection with the Business Combination. Nextdoor has not yet completed its closing procedures for the fiscal year ended December 31, 2020 or the three months ended March 31, 2021. This Presentation contains certain estimated preliminary financial results and key operating metrics for the fiscal year ended December 31, 2020 and the three months ended March 31, 2021. This information is preliminary and subject to change. As such, our actual results may differ from the estimated preliminary results presented here and will not be finalized until we complete of our year-end accounting procedures. 2 Disclaimer This Presentation (together with oral statements made in connection herewith, the “Presentation”) relates to the proposed business combination (the “Business Combination”) between Khosla Ventures Acquisition Co.

3 Disclaimer This presentation includes certain non-GAAP financial measures (including on a forward-looking basis). These non-GAAP measures are an addition, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP and should not be considered as an alternative to their nearest GAAP equivalent or any other performance measures derived in accordance with GAAP. A reconciliation of the non-GAAP financial measures used in this Presentation to their nearest GAAP equivalent is included in the appendix to this Presentation. Nextdoor believes that these non-GAAP measures of financial results (including on a forward-looking basis) provide useful supplemental information to investors about Nextdoor. Nextdoor’s management uses forward-looking non-GAAP measures to evaluate Nextdoor’s projected financials and operating performance. However, there are a number of limitations related to the use of these non-GAAP measures and their nearest GAAP equivalents, including that they exclude significant expenses that are required by GAAP to be recorded in Nextdoor’s financial measures. In addition, other companies may calculate non-GAAP measures differently, or may use other measures to calculate their financial performance, and therefore, Nextdoor’s non-GAAP measures may not be directly comparable to similarly titled measures of other companies. Additionally, to the extent that forward-looking non-GAAP financial measures are provided, they are presented on a non-GAAP basis without reconciliations of such forward-looking non-GAAP measures due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations.

37 Risk Factors Risks Related to Nextdoor’s Business and Industry Following the [Business Combination] 1. Nextdoor has a limited operating history at the current scale of its business and is still scaling up its monetization efforts, which makes it difficult to evaluate its current business and future prospects, and there is no assurance it will be able to scale its business for future growth. 2. Nextdoor generates substantially all of its revenue from advertising. If advertisers reduce or eliminate their spending with Nextdoor, Nextdoor’s business, operating results, and financial condition would be adversely impacted. 3. Nextdoor’s ability to attract and retain advertisers depends on its ability to collect and use data and develop products to enable it to effectively deliver and accurately measure advertisements on the Nextdoor platform. 4. If Nextdoor fails to add new neighbors or retain current neighbors, or if current neighbors engage less with Nextdoor, its business, operating results, and financial condition would be adversely impacted. 5. Nextdoor’s business is highly competitive. Competition presents an ongoing threat to the success of Nextdoor’s business. 6. Nextdoor’s business is dependent on its ability to maintain and scale its product offerings and technical infrastructure, and any significant disruption in the availability of Nextdoor’s platform could damage Nextdoor’s reputation, result in a potential loss of neighbors and engagement, and adversely affect Nextdoor’s business, operating results, and financial condition. 7. Nextdoor has experienced rapid growth and expects to invest in its growth for the foreseeable future. If Nextdoor fails to manage its growth effectively, its business, operating results, and financial condition would be adversely affected. 8. If Nextdoor does not successfully anticipate market needs and develop products and services and platform enhancements that meet those needs, or if those products, services and platform enhancements do not gain market acceptance, its business, operating results, and financial condition will be adversely impacted. 9. If Nextdoor’s efforts to build strong brand identity and reputation are not successful, it may not be able to attract or retain neighbors, and its business, operating results, and financial condition will be adversely affected. 10. Unfavorable media coverage negatively affects Nextdoor’s business from time to time. 11. Health epidemics, including the COVID-19 pandemic have had or could have an adverse impact on Nextdoor’s business, operations and the markets and communities in which Nextdoor, its partners and its customers operate. 12. Nextdoor plans to continue expanding its international operations where it has limited operating experience and may be subject to increased business and economic risks that could seriously harm its business, operating results, and financial condition. 13. If Nextdoor needs additional capital in the future, it may not be available on favorable terms, if at all. 14. Nextdoor plans to continue to make acquisitions, which could harm its financial condition or results of operations and may adversely affect the price of its Class A common stock. 15. Nextdoor’s business depends largely on its ability to attract and retain talented employees, including senior management. If Nextdoor loses the services of Sarah Friar, its Chief Executive Officer, or other members of its senior management team, Nextdoor may not be able to execute on its business strategy. 16. Nextdoor’s core values may conflict with the short-term interests of its business. 17. Nextdoor is dependent on Google Ad Manager (“GAM”) for a substantial majority of its revenue. Any failure or change in the GAM product or its terms and conditions, data usage or pricing could adversely affect Nextdoor’s business, operating results, and financial condition. 18. Nextdoor relies on third-party software and service providers, including Amazon Web Services (“AWS”), to provide systems, storage and services for its platform. Any failure or interruption experienced by such third parties, including as a result of the COVID-19 pandemic, could result in the inability of neighbors and advertisers to access or utilize Nextdoor’s platform, and adversely impact Nextdoor’s business, operating results, and financial condition. 19. Nextdoor relies on third parties, including email providers, mobile data networks, geolocation providers and the United States Postal Service (“USPS”) to verify its neighbors’ addresses. Any failure or interruption experienced by such third parties, including the USPS, could result in the inability of neighbors to join Nextdoor’s platform, resulting in harm to Nextdoor’s reputation and an adverse impact to its business, operating results, and financial condition. 20. Technologies have been developed that can block the display of advertisements on the Nextdoor platform, which could adversely impact its business, operating results, and financial condition. 21. Security breaches and improper access to or disclosure of Nextdoor’s data or its neighbors’ data, or other hacking and phishing attacks on Nextdoor’s or third-party systems, could harm its reputation and adversely affect its business. 22. Distribution and marketing of, and access to, Nextdoor’s platform depends, in significant part, on a variety of third-party publishers and platforms (including mobile app stores, third party payment providers, computer systems, and other communication systems and service providers). If these third parties limit, prohibit or otherwise interfere with or change the terms of the distribution, use or marketing of Nextdoor’s platform in any material way, it could materially adversely affect Nextdoor’s business, operating results, and financial condition. 23. Nextdoor’s platform and internal systems rely on software and hardware that is highly technical, and any errors, bugs, or vulnerabilities in these systems, or failures to address or mitigate technical limitations in Nextdoor’s systems, could adversely affect its business. 37 Risk Factors Risks Related to Nextdoor’s Business and Industry Following the [Business Combination] 1.

Nextdoor’s business is dependent on its ability to maintain and scale its product offerings and technical infrastructure, and any significant disruption in the availability of Nextdoor’s platform could damage Nextdoor’s reputation, result in a potential loss of neighbors and engagement, and adversely affect Nextdoor’s business, operating results, and financial condition. 7. Nextdoor has experienced rapid growth and expects to invest in its growth for the foreseeable future. If Nextdoor fails to manage its growth effectively, its business, operating results, and financial condition would be adversely affected. 8. If Nextdoor does not successfully anticipate market needs and develop products and services and platform enhancements that meet those needs, or if those products, services and platform enhancements do not gain market acceptance, its business, operating results, and financial condition will be adversely impacted. 9. If Nextdoor’s efforts to build strong brand identity and reputation are not successful, it may not be able to attract or retain neighbors, and its business, operating results, and financial condition will be adversely affected. 10. Unfavorable media coverage negatively affects Nextdoor’s business from time to time. 11. Health epidemics, including the COVID-19 pandemic have had or could have an adverse impact on Nextdoor’s business, operations and the markets and communities in which Nextdoor, its partners and its customers operate. 12. Nextdoor plans to continue expanding its international operations where it has limited operating experience and may be subject to increased business and economic risks that could seriously harm its business, operating results, and financial condition. 13. If Nextdoor needs additional capital in the future, it may not be available on favorable terms, if at all. 14. Nextdoor plans to continue to make acquisitions, which could harm its financial condition or results of operations and may adversely affect the price of its Class A common stock. 15. Nextdoor’s business depends largely on its ability to attract and retain talented employees, including senior management. If Nextdoor loses the services of Sarah Friar, its Chief Executive Officer, or other members of its senior management team, Nextdoor may not be able to execute on its business strategy. 16. Nextdoor’s core values may conflict with the short-term interests of its business. 17. Nextdoor is dependent on Google Ad Manager (“GAM”) for a substantial majority of its revenue. Any failure or change in the GAM product or its terms and conditions, data usage or pricing could adversely affect Nextdoor’s business, operating results, and financial condition. 18. Nextdoor relies on third-party software and service providers, including Amazon Web Services (“AWS”), to provide systems, storage and services for its platform. Any failure or interruption experienced by such third parties, including as a result of the COVID-19 pandemic, could result in the inability of neighbors and advertisers to access or utilize Nextdoor’s platform, and adversely impact Nextdoor’s business, operating results, and financial condition. 19. Nextdoor relies on third parties, including email providers, mobile data networks, geolocation providers and the United States Postal Service (“USPS”) to verify its neighbors’ addresses. Any failure or interruption experienced by such third parties, including the USPS, could result in the inability of neighbors to join Nextdoor’s platform, resulting in harm to Nextdoor’s reputation and an adverse impact to its business, operating results, and financial condition. 20. Technologies have been developed that can block the display of advertisements on the Nextdoor platform, which could adversely impact its business, operating results, and financial condition. 21. Security breaches and improper access to or disclosure of Nextdoor’s data or its neighbors’ data, or other hacking and phishing attacks on Nextdoor’s or third-party systems, could harm its reputation and adversely affect its business. 22. Distribution and marketing of, and access to, Nextdoor’s platform depends, in significant part, on a variety of third-party publishers and platforms (including mobile app stores, third party payment providers, computer systems, and other communication systems and service providers). If these third parties limit, prohibit or otherwise interfere with or change the terms of the distribution, use or marketing of Nextdoor’s platform in any material way, it could materially adversely affect Nextdoor’s business, operating results, and financial condition. 23. Nextdoor’s platform and internal systems rely on software and hardware that is highly technical, and any errors, bugs, or vulnerabilities in these systems, or failures to address or mitigate technical limitations in Nextdoor’s systems, could adversely affect its business.

38 Risk Factors Risks Related to Financial and Accounting Matters 1. Nextdoor’s operating results may fluctuate significantly, which makes its future results difficult to predict. 2. Certain of Nextdoor’s market opportunity estimates, growth forecasts and key metrics could prove to be inaccurate, and any real or perceived inaccuracies may harm its reputation and negatively affect its business. 3. Nextdoor has a history of net losses and may experience net losses in the future and Nextdoor cannot assure you that it will achieve or sustain profitability. If Nextdoor cannot achieve and sustain profitability, its business, financial condition, and operating results will be adversely affected. 4. Nextdoor’s ability to use its U.S. federal and state net operating losses to offset future taxable income may be subject to certain limitations which could subject Nextdoor’s business to higher tax liability. 5. Nextdoor’s financial results may be adversely affected by changes in accounting principles generally accepted in the United States and its financial estimates may be different from its financial results. 6. If currency exchange rates fluctuate substantially in the future, Nextdoor’s operating results, which are reported in U.S. dollars, could be adversely affected. 7. Nextdoor may have exposure to greater-than-anticipated tax liabilities, which could seriously harm its business. 8. Taxing authorities in the U.S. and in foreign jurisdictions may successfully assert that Nextdoor should have collected or in the future should collect sales and use, gross receipts, value-added or similar taxes and may successfully impose additional obligations on Nextdoor, and any such assessments or obligations could adversely affect Nextdoor’s business, operating results, and financial condition. 9. The interpretation and application of recent U.S. tax legislation or other changes in U.S. or non-U.S. taxation of Nextdoor’s operations could harm its business, operating results, and financial condition. Risks Related to Legal and Regulatory Matters 10. Nextdoor may be liable as a result of content or information that is published or made available on its platform. 11. Actions by governments that restrict access to Nextdoor’s platform in their countries, or that otherwise impair Nextdoor’s ability to sell advertising in their countries, could substantially harm Nextdoor’s business, operating results, and financial condition. 12. Nextdoor’s business is subject to complex and evolving U.S. and foreign laws, regulations and industry standards regarding data privacy, cybersecurity, intellectual property (including copyright and patent laws), content, rights of publicity, advertising, marketing, competition, protection of minors, consumer protection, taxation, and telecommunications, and other matters, and it cannot yet determine the impact that such future laws, regulations and industry standards may have on Nextdoor’s business. Many of these laws and regulations are subject to change and uncertain interpretation, and could result in claims, changes to Nextdoor’s business practices, monetary penalties, increased cost of operations, or declines in neighbor growth or engagement, or otherwise harm Nextdoor’s business, operating results, and financial condition. 13. Nextdoor could be involved in legal disputes that are expensive and time consuming, and, if resolved adversely, could harm its business, operating results, and financial condition. 14. Exposure to United Kingdom political developments, including the effect of its withdrawal from the European Union, could be costly and difficult to comply with and could adversely impact Nextdoor’s business, operations results, and financial condition. 15. The obligations associated with operating as a public company following the [Business Combination] will require significant resources and management attention and will cause Nextdoor to incur additional expenses, which will adversely affect its profitability. 16. Failure to maintain effective systems of internal control and disclosure controls could have a material adverse effect on Nextdoor’s business, operating results, and financial condition. Risks Related To Intellectual Property 17. If Nextdoor is unable to protect its intellectual property, the value of its brands and other intangible assets may be diminished, and its business, operating results, and financial condition may be adversely affected. 18. Confidentiality agreements with employees and others may not adequately prevent disclosure of trade secrets and proprietary information. 19. Nextdoor’s use of “open source” software could subject it to possible litigation or could prevent it from offering products that include open source software or require it to obtain licenses on unfavorable terms. Risks Related to Ownership of Nextdoor’s Class A Common Stock 20. The dual class structure of Nextdoor’s common stock may adversely affect the trading market for its Class A common stock following the closing of the transaction. 21. The dual class structure of Nextdoor’s common stock will have the effect of concentrating voting power with Nextdoor’s management and other existing stockholders, which will limit your ability to influence the outcome of important transactions, including a change in control. 22. Nextdoor does not intend to pay dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of Nextdoor’s Class A common stock.38 Risk Factors Risks Related to Financial and Accounting Matters 1.
