Large banks and institutions can afford to pay past regulatory & infra barriers but in our time building APIs for brokerage like TradeStation and interviewing developers/entrepreneurs we found that not only does Fintech have one of the highest startup failure rates but most of those failures can boil down to regulation, data fees, and infra hurdles that fintech entrepreneurs need to jump over. We’re designed to do all of the leg work so that builders can focus on building and getting to market from day one.
To show off the power of our engine product we built two, soon to be open source, flagship products people can use to trade US equities and options. The first is Aries Infinite which is an infinite canvas product for trading and the second is a low latency mobile trading app for US capital markets. You can see them both at Aries.com
Maybe I'm behind the times but this not exactly what I think of as "fintech".
