I was born in London, UK and raised in Tokyo, Japan and the Bay Area. I co-founded Alpha Vantage in 2017, an API/dev tools company that was fortunate to be in the Summer 2018 batch. Today I continue to run Alpha Vantage day-to-day while also doing angel investing (mostly YC startups) on the side.
Cofounder of Alpha Vantage
Founded 2017 · Source
Alpha Vantage began as a passion project started by the founders while they were attending grad school together. The idea was conceived through a shared interest in the stock markets and investing as well as a fundamental desire to make something that the founders themselves would want to use. Truthfully, the founders did not originally build Alpha Vantage with the intention of creating a business out of it, but the exponential user adoption and intensity of usage made the decision to start a business natural and obvious - as well as the best way for us to serve our users (and eventually paying customers).
