Keynote

Open Source, Community, and Consequence: The Story of MongoDB

Wednesday Nov 19 / 09:00AM PST, Grand Ballroom at Hyatt Regency, San Francisco

Abstract

The story of MongoDB started with a frustration instead of a business plan. Databases were rigid and slow to evolve while the rest of the tech stack was moving faster. This frustration showed up at meetups, in passionate arguments on forums - and we used it to listen, learn, and build in the open. The community became co-conspirators rather than users.

Sure, we made mistakes, shipped features fast, and were often humbled. But what looked like mistakes resulted in continuous improvements in the code, new features, and a growth in the  community around it.

In this talk, we trace that journey, and share our architectural bets, and the hard lessons we learned in building trust and resilience at scale. The product tenets that turned early skepticism into widespread adoption. We will share the way open source & community turned into the engine of a sustainable and formidable business. And why we chose to monetize developer convenience instead of control. How we earned enterprise trust without compromising our values, and how a developer-first philosophy became a competitive moat.

This is the story of an underdog that didn’t come from Silicon Valley. Hopefully, we will inspire you to build in the MongoDB way, by making long-term bets, and by building formidable businesses through open source & community.
