Questions & Answers

As answered by people managing Sourcegraph and Pencil Project.

What's the story behind your product?

Sourcegraph's answer

Quinn Slack and Beyang Liu founded Sourcegraph in 2013. They met at Stanford and later worked together at Palantir, where they saw how hard it was for developers to understand large enterprise codebases. Engineers at Google had strong internal code search, and almost nobody else did. Sourcegraph set out to give every company that ability. It started as universal code search, grew into code intelligence and large-scale automated changes, and now provides the context layer for AI agents. The pitch has stayed the same throughout: AI makes it faster to write code, which makes knowing what’s in your codebase more important, and Sourcegraph is the source of truth for that code.

Who are some of the biggest customers of your product?

Sourcegraph's answer

  • 1Password
  • Indeed
  • Canva
  • Stripe
  • Dropbox
  • Hubspot
  • BlackStone
  • Mistral
  • Reddit
  • MathWorks

Why should a person choose your product over its competitors?

Sourcegraph's answer

Most alternatives are tied to one code host or are coding assistants that only see the repo in front of them. Sourcegraph sits beneath those tools rather than replacing them. It makes Claude Code, Cursor, Copilot, and Codex more accurate by giving them context from the whole codebase.

How would you describe the primary audience of your product?

Sourcegraph's answer

Large engineering organizations with big, sprawling codebases spread across many repos and code hosts, often in regulated industries like financial services. The buyers are the VP of Engineering (productivity and AI ROI), the Head of Platform/DevEx (developer tooling, migrations, agent infrastructure), and the CISO (finding vulnerabilities and fixing them across the codebase). Day-to-day users are developers, platform teams, and increasingly AI agents.

What makes your product unique?

Sourcegraph's answer

  • Coverage: it searches across all code hosts at once, including sub-branches, which GitHub’s native search can’t do.
  • Permissions: it syncs access rules from each code host, so people and AI agents only see code they’re allowed to see.
  • Two kinds of results: Code Search gives exact, repeatable matches, and Deep Search adds agentic investigation with cited sources.

The MCP Server gives the same context to whatever AI agents a team already uses, and Agentic Batch Changes turns a plain-language request into pull requests across hundreds of repos.
