We believe…

  1. Artificial Intelligence is not magic. The technology is only useful if it’s easy to understand.
  2. The best AI products won’t be built from boxed solutions. Developers need custom models and transparent tools, not just cloud services.
  3. AI software needs better developer and user experience. This requires hybrid skill sets and radical attention to detail.
  4. If you ship it, you should own it. We believe in taking responsibility for our software, and letting you do the same.
  5. Technology should be accessible. We want to provide the most value with open-source software. That’s why we’ve built spaCy and our other tools and libraries.
  6. We’re not your typical startup. We’re boot­strapped, independent and put stability over moonshots.
