About us

Filament is reimagining the professional group chat for the AI age. One where new ideas and collaborations cross company borders, where trust is paramount and where groups are networked not siloed. Because the true potential value of AI isn’t replacing human intelligence. It’s connecting it.

  • The company is venture-backed with co-founders including the Founding CEO of Chartbeat and Scroll, the Head of Engineering at the MIT Center for Constructive Communication, the Head of App engineering at Foursquare and the S&O lead for innovation at Twitter.

  • We believe in fixed deadlines but variable scope and doing as few things concurrently as possible. We prize adaptability and think that speed comes from clarity of purpose not from making people work weekends. We’re a small team and folks are expected to ask lots of questions but be able to work independently. We like open-sourcing things when we can, it feels good.

  • We work on east-coast time, but are flexible on location within the Americas. Bay Area, Boston and NYC make life easier for get-togethers than Punta Arenas.
