Alpaca raises $52M Series C to take its API brokerage platform to new markets

But it’s still quite difficult for investors in other parts of the globe to trade stocks on U.S. exchanges. A San Mateo-based startup called Alpaca has quietly capitalized on that opportunity by offering an API to financial services firms that lets them sell trading services to their consumer user bases. Today, Alpaca claims it serves more than 5 million brokerage accounts, and has more than 200 financial clients in 40 countries. Alpaca recently also teamed up with Kraken to let the crypto exchange’s users trade U.S. stocks and ETFs in some states. The Series C comes roughly 18 months after Alpaca secured a Series B extension in October 2023.
