Retail investors are famously locked out of the startup world. Robinhood is attempting to change that by allowing the general public to invest in a portfolio of what it calls “some of the most exciting private companies operating today.”

To do this, the company that pioneered the commission-free brokerage model has secured access to eight startups—including Databricks, Stripe, Mercor, and Oura—grouping them into a vehicle called Robinhood Ventures Fund I. The fund, which also includes Ramp, Airwallex, Revolut, and Boom, set out last month with an ambitious $1 billion target, but demand for this novel way of investing in private companies was lower than expected.
