David Kelly
I build consumer SaaS products that acquire their own users.
As Founding GM and Head of Product at AppSumo Originals, I took 9 products from zero to 1M+ users in 180+ countries. 3 crossed $1M in lifetime revenue (vs. 4% industry norm).
I build with AI daily: Claude Code, Codex, Lovable, and Replit. 300+ merged PRs across client and open-source work in 2026, plus two open-source MCP servers.
