As of the reports dates, the Company has signed four clients in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. CASH Cash include cash on hand and on deposit at banking institutions as well as all highly liquid short-term investments with original maturities of 90 days or less. Cash amounted to $244,089 and $0 as of December 31, 2018 and 2017, respectively. CONCENTRATION OF RISK Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash.

All of the Company’s cash is held in bank accounts in the United States and is protected by FDIC insurance. $0 and $0 are amounts that are not covered by FDIC insurance as of December 31, 2018 and 2017, respectively. REVENUE RECOGNITION The Company adopted Accounting Standards Codification (“ASC”) 606. ASC 606, Revenue from Contracts with Customers, establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity’s contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those services recognized as performance obligations are satisfied. The Company has assessed the impact of the guidance by performing the following five steps analysis: Step 1: Identify the contract Step 2: Identify the performance obligations Step 3: Determine the transaction price Step 4: Allocate the transaction price Step 5: Recognize revenue Based on the assessment, the Company concluded that there was no change to the timing and pattern of revenue recognition for its current revenue streams in scope of Topic 606 and therefore there were no material changes to the Company’s consolidated financial statements upon adoption of ASC 606. The Company recognizes revenue from providing consulting services as of December 31,2018. Customer makes full payment at time of purchase. The Company does not offer customers right of refund. The Company had net revenue of $15,915 and $0 for the twelve months ended December 31,2018 and 2017, respectively. INCOME TAXES Under ASC 740, “Income Taxes,” deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Valuation allowances are established when it is more likely than not that some or all of the deferred tax assets will not be realized. As of December 31, 2018 and 2017, there were no deferred taxes due to the uncertainty of the realization of net operating loss or carry forward prior to expiration. LOSS PER COMMON SHARE Basic loss per common share excludes dilution and is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted loss per common share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the loss of the entity. As of December 31, 2018 and 2017, there are no outstanding dilutive securities. FAIR VALUE OF FINANCIAL INSTRUMENTS The Company follows guidance for accounting for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or disclosed at fair value in the financial statements on a recurring basis. Additionally, the Company adopted guidance for fair value measurement related to nonfinancial items that are recognized and disclosed at fair value in the financial statements on a nonrecurring basis. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. The carrying amounts of financial assets such as cash approximate their fair values because of the short maturity of these instruments. RECENT ACCOUNTING PRONOUNCEMENTS ASU 2016-02, Leases (Topic 842). The standard requires a lessee to recognize a liability to make lease payments and a right-of-use asset representing a right to use the underlying asset for the lease term on the balance sheet. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact that this standard will have on our consolidated financial statements. Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force) and the United States Securities and Exchange Commission did not or are not believed by management to have a material impact on the Company’s present or future financial statements.

CONCENTRATION OF RISK

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash. Cash amounted to $244,089 and $0 as of December 31, 2018 and 2017, respectively. All of the Company’s cash is held in bank accounts in the United States and is protected by FDIC insurance. $0 and $0 are amounts that are not covered by FDIC insurance as of December 31, 2018 and 2017, respectively.

REVENUE RECOGNITION

The Company adopted Accounting Standards Codification (“ASC”) 606. ASC 606, Revenue from Contracts with Customers, establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity’s contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those services recognized as performance obligations are satisfied.

The Company has assessed the impact of the guidance by performing the following five steps analysis:

Step 1: Identify the contract

Step 2: Identify the performance obligations

Step 3: Determine the transaction price

Step 4: Allocate the transaction price

Step 5: Recognize revenue

Based on the assessment, the Company concluded that there was no change to the timing and pattern of revenue recognition for its current revenue streams in scope of Topic 606 and therefore there were no material changes to the Company’s consolidated financial statements upon adoption of ASC 606.

The Company recognizes revenue from providing consulting services as of December 31,2018. Customer makes full payment at time of purchase. The Company does not offer customers right of refund.

The Company had net revenue of $15,915 and $0 for the twelve months ended December 31,2018 and 2017, respectively.

INCOME TAXES

Under ASC 740, “Income Taxes,” deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Valuation allowances are established when it is more likely than not that some or all of the deferred tax assets will not be realized. As of December 31, 2018 and 2017, there were no deferred taxes due to the uncertainty of the realization of net operating loss or carry forward prior to expiration.

LOSS PER COMMON SHARE

Basic loss per common share excludes dilution and is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted loss per common share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the loss of the entity. As of December 31, 2018 and 2017, there are no outstanding dilutive securities.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company follows guidance for accounting for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or disclosed at fair value in the financial statements on a recurring basis. Additionally, the Company adopted guidance for fair value measurement related to nonfinancial items that are recognized and disclosed at fair value in the financial statements on a nonrecurring basis. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3 inputs are unobservable inputs for the asset or liability. The carrying amounts of financial assets such as cash approximate their fair values because of the short maturity of these instruments.

RECENT ACCOUNTING PRONOUNCEMENTS

ASU 2016-02, Leases (Topic 842). The standard requires a lessee to recognize a liability to make lease payments and a right-of-use asset representing a right to use the underlying asset for the lease term on the balance sheet. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact that this standard will have on our consolidated financial statements.

Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force) and the United States Securities and Exchange Commission did not or are not believed by management to have a material impact on the Company’s present or future financial statements.
