I’m very excited to share that today we announced our plans to go public through a SPAC merger with Duddell Street Acquisition Corp.  

When my co-founders and I bootstrapped our way out to Silicon Valley in the summer of 2013, we had a vision to leverage technology to better connect the world to their governments. Ever since, this has been the north star. It has been a tremendous ride — one filled with its fair share of highs and lows, but ultimately I have always been proud of our leadership in delivering you the trusted products you need in order to operate in today’s constantly evolving corporate, legal, regulatory, and policy landscape. 

We would not be in this position without you, our thousands of valued customers, who rely on the products and communities we build, the information we gather, and the journalism we produce. This is an incredibly humbling position to be in -- one of sacred trust to provide non-partisan and data-driven insights to our customers and readers, while building robust communities that can focus on what matters. I extend my sincerest gratitude for your support as members of our extended global community. 

As we look at the world today -- and our future -- the pace of political, legal, legislative, and regulatory activity is unrelenting, and only speeding up. Autonomous cars, digital currencies, online sports betting, the gig economy -- and many other regulated sectors of the future are operating in today’s legal equivalent of a wild west. FiscalNote is positioned to not only continue to deliver the trusted products and services you already rely on, but also a new era of innovation that will help you be even more informed and effective.

We are thrilled to bring you into this next phase of our journey as we build an even greater platform to create a transparent and connected global society. Specifically, this evolution of FiscalNote into the public markets will bring resources to bear that will enable us to serve you with more innovative software and solutions, broader and deeper data sets, and even more robust insights and analysis. 

I’m excited about what lies ahead for FiscalNote. Every customer played such a critical role in helping us get to where we are today, and I look forward to what we will accomplish together in this next stage of our FiscalNote narrative. 

And as always, if you have any questions, please don’t hesitate to contact your account manager or reports@curatesolutions.com. Thank you again for your support.

Sincerely, 

Tim Hwang
