Founder at Delivering Growth
Javid Jamae has led experimentation and growth engineering at Postman, Achieve, and Earnest, shipping roughly 150 product experiments across Postman, Skipcard, Tout, and Freedom/Achieve and building the infrastructure under them: feature flagging, deterministic assignment, exposure logging, and analytics pipelines. He runs the Delivering Growth community and built the free A/B-testing calculators on this site. These days he also operates a portfolio of AI-run products, so the failures and numbers in these posts come from systems he runs himself.
