The financial industry is growing at a record pace, but our data providers are still stuck in the past — with cumbersome onboarding processes, complicated APIs, slow infrastructure, and expensive licensing costs.

Databento is the next-generation market data provider — with the radical idea that you should only pay for the data that you use. We power the world's largest finance and fintech institutions and lower the barrier of entry for small startups.

Since starting in 2019, we've raised over $27.8M in funding and have over 2,000 companies signed up pre-launch. Our team consists of former data users from firms like Two Sigma, Belvedere, Pico, Bloomberg, Pinterest, and Google.

We offer health, dental, disability, and life insurance benefits, as well as 401(k) matching and visa sponsorships. We accommodate 100% remote work, with teammates living around the globe and paid in their local currency.
