DraftKings deployed DraftCode, an internally built AI-powered code review assistant, to help engineering teams automatically review pull requests and catch potential issues before human review.

DraftKings confirmed on its careers blog that it built and deployed DraftCode, an internal AI-powered code review tool, to expedite the review of pull requests submitted by engineers. As of the company's March 2026 investor day, DraftKings stated that 100% of code reviews are now AI-assisted, and reported a 40% improvement in engineering hour productivity. DraftKings co-founder Paul Liberman described the approach as having 'AI do things like identify problems with our code before an engineer would do it—as a supplement for code reviews.' Engineers also use external tools including GitHub Copilot, Cursor, and Claude Code.
