Assaf Arkin is a seasoned founder and software leader with 18 years of experience building products that blend AI, full‑stack engineering, and practical entrepreneurship. Based in Los Angeles, he currently runs Rentail—using conversational AI to match merchants to retail spaces—and launched cite.me.in to monitor AI citation of websites, demonstrating a knack for timely, product‑led AI utilities. Previously CTO at multiple companies and a long‑time open‑source contributor, his work spans backend systems, headless browser testing, and integrations (notably contributions to Hubot and the Vanity A/B testing library). He co‑authored a technical Manning book and has a track record of turning fragile early products into reliable, scalable platforms that attract acquisition interest. Comfortable toggling between code and strategy, he often pairs engineering depth with product intuition to ship pragmatic solutions. An unexpected thread through his career is a consistent focus on measurement—experiments, analytics, and testing—to drive better product decisions.
