Summary
Robert Day is a Head of Engineering and founder with 15 years building social, crypto, and fintech products from early startups to exits. Based in the San Francisco Bay Area, he blends hands-on engineering roots (Ruby and full-stack roles at Wildfire/Google and Nature Publishing) with leadership experience scaling teams as VP/Director and preparing companies for acquisition. As CEO and founder of Gather and earlier Mantissa, he pairs product-led entrepreneurship with operational rigor, and at StyleSeat helped steer a major business-model transition to profitability. Currently leading engineering at The Dip App, he’s comfortable shipping fast in high-ambiguity environments while reducing technical debt and instilling QA and cross-functional discipline. Notably, his career shows a pattern of joining growth-stage teams to drive structure, cost control, and exit readiness rather than just feature delivery.
