After his first child was born, Matt Wonlaw (@tantaman) imagined giving his son life advice. What kind of life did he want his kid to lead? At the time, he was working for Facebook, and he decided that his own life needed a change in direction. So Matt started vlcn, aka Vulcan Labs, a research company that develops open-source projects like CR-SQLite and Materialite. vlcn has an unusual business model – Matt receives donations and sponsorships from users and clients. It’s all part of his mission to rethink the modern data stack for writing rich and complex applications.
