Borehole

Borehole is software for technical due diligence on acquisitions and investments. It reads a code repository, including its Git history, and rates the code for a deal team. Andrew Edmond, who was previously chief technology officer at Woot.com, launched it on Hacker News on 4 October 2026.

What Borehole offers

• Repository reading: reads the working tree and full Git history of a repository hosted on GitHub, GitLab, Azure DevOps, Bitbucket, Codeberg, Gitea or SourceHut.
• Seven dimensions: rates the code across seven areas that a deal team cares about, using 106 checks.
• Open questions: turns what the code cannot answer into questions for management.
• Private repositories: a collector can run on the target's own systems, and sends facts and short excerpts of up to 120 characters rather than whole files.

Who it serves

The tool is aimed at buyers and investors assessing software companies before a deal. The maker says its founder has carried out technical diligence across dozens of Amazon deals.
