We chose to partner with Alpaca for many reasons. Still, we want to highlight Alpacaâs ability to differentiate as an API-first company and provide an unparalleled brokerage as a service to InvestSky.

We also really appreciate how supportive Alpacaâs leadership is towards partners." - Turki Alshaikh, Co-Founder of Investsky
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
Alpacaâs Broker API has everything needed to build a full-fledged trading application out of the box. Building our backend infrastructure on top of Broker API was easier than expected, given their extensive documentation, ready-to-test sandbox environment, and professional support." - Abdulrahman Al Kharafi, CEO of Zad App & Head of Fintech Securities House
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
Alpaca has been a great business partner. The Broker API team has been highly responsive and professional throughout our integration and launching journey. They have helped us significantly in decreasing time-to-market by having a well-documented process." - Saleeh Alaqeel, Cofounder and COO at Abyan Capital
