Founded in 2015, Third Party Trade offers APIs to power the core functionalities of a brokerage. In short, this means firms looking to offer trading to their customers can focus on building the front-end experience customers interact with, and a sales and marketing engine, without having to do the heavy lifting of building back-end brokerage functionality.
Companies like Third Party have proven to be a backbone to fueling the uptick of commission-free and low-commission brokerages.
In a 2015 interview, Third Party CEO Michael Giles said the company raised a small amount of capital, but has primarily funded its growth with revenue. Giles was a speaker at the 2018 Benzinga Global Fintech Awards.
