Lol, we had literally this exact startup: TradeIt (https://web.archive.org/web/20200817053226/https://www.trade...). Launched about 7 years ago, had official OAuth integrations with most major brokers, an API, and native mobile SDKs that had customizable UI for portfolio/order management/trading/market data. We had some really big customers like Yahoo Finance. Sold to another company about 3 years ago. The buyers had no idea what they were buying and let it rot and eventually shut it all down. Fun times. If we could have held on until WSB went viral a few years back I think we could have been very big. Oh well. Maybe you guys can succeed where we left off. Good luck!
