About Us

Culture and Values

Stay curious

  • Curiosity conquers conflict & enriches debate. A culture that approaches debate and conflict with curiosity finds new paths forward & delivers exceptional results. We never want to be blinded by past experience & assumptions.

Trust by default

  • We’re a team of talented high performers, and if you’re on the team, we already saw that potential in you. So expect to be empowered and relied on Day 1. We hire great people & trust them to do great things.

Obsess about customers

  • The customer motivates everything we do. We’re inventing things for real people to solve real problems. We’re not building for ourselves. This means we don’t celebrate what we ship – we celebrate the impact we see for our customers. And: there’s always more to do. We always see opportunities to be better and do more for them.

Think long / act short

  • We stop and think about the long-term impact of our decisions, but we don’t get lost in planning or trying to be perfect. We have a vision for the future and we act quickly to make progress toward it. We embrace a culture of iteration, experimentation, and learning. We “measure once, cut once.” And we make every day count toward our goals.

Choose team first

  • We put each other ahead of ourselves. We’re all here to grow, cultivating a courageous and dedicated team that values commitment and collaboration over expertise. Everyone on the team has a voice & a seat at the table.
