We exist to make investing in the private markets as easy as Robinhood did for public stocks. More and more people invest in private equity and venture capital every day. Even though this asset class has been around for decades, it wasn't built to handle this volume of investors. Signing up for Robinhood? It takes two minutes. Investing in a VC fund? You've got to fill out a 200-question questionnaire each time that you make an investment. The forms aren't standardized and not every question applies to every investor. Investors miss questions or answer the wrong ones and then have to redo the entire thing. We built a TurboTax-style workflow for investors to only see the questions that matter to them and see every question that matters to them to make fund closing (i.e. the process of investing into a VC fund) easy. Our world record document completion time is two minutes. That may sound boring but we've processed billions of dollars for thousands of investors. And by having an investor run through our workflow, we capture their identity so we can allow them to repurpose it wherever they'd like in the future. We call this an "investor passport" and it's the whole reason we built this business. This is the first fund workflow that we're automating.
