San Francisco, California, United States
Summary
🤩
Rockstar🎓
Top SchoolAllen Kleiner is a pragmatic engineering lead with 12 years of experience building growth-focused product teams and shipping web and design-system driven experiences from 0→1 and 1→10. He blends hands-on engineering (notably contributions to Segment’s Evergreen React UI framework) with product, UX, and GTM collaboration to drive measurable self-service revenue lifts and enterprise adoption. At companies from Pinterest to Segment, Pave, Tome and now Retool, he’s repeatedly scaled teams, rewired design systems, and moved activation and ARR metrics through data-informed experiments. He excels as a player-coach—hiring, coaching, and shipping with teams—while also partnering post-sales to ensure enterprise customers realize product value. Based in San Francisco and grounded in strong front-end and design-system expertise, he’s as comfortable authoring docs and components as he is defining strategic product roadmaps.
