Employee Review Themes

The good and the hard parts

✓ What employees love

  • ✓ Open-source AI infrastructure — real mission alignment, not just marketing
  • ✓ Small team with outsized research output; your work has direct impact
  • ✓ Strong compensation for stage — competitive with much larger companies
  • ✓ Collaborative, low-ego culture where ideas win on merit

✗ What could be better

  • ✗ Early-stage means wearing many hats constantly — not for specialists
  • ✗ Limited career ladder; growth paths are still being defined
  • ✗ Fast-changing priorities as the AI infra landscape shifts rapidly
  • ✗ Less brand recognition than competitors like OpenAI or Anthropic
