Managed Research

Overnight research engineering

Point us at a repo, a spec, and example traces. We try approaches overnight and open a PR with what worked.

  • - We read your code, try ideas, and compare them on your data
  • - You get a PR with diffs and commands to reproduce everything
  • - Runs under time and spend caps you set
