Alpaca has been a great business partner. One of the reasons we chose Alpaca is due to their Local Currency Trading API. We believe this offering will simplify the trading experience for Japanese investors by providing access to US stocks in local currency without having to convert to the US dollar at any point." - Brian Yun, Co-Founder at Woodstock

Before Alpaca, companies like ours would likely have undergone the grueling, complex process to become a broker themselves, taking up a significant amount of time, dev resources, and legal resources. Alpaca is one of the most important companies in our stack, and has made it significantly easier for companies to bring their product to market." - Som Mohapatra, CIO and Co-founder at Quantbase
