Summary
👤
Senior🎓
Top SchoolDavid Geismar is a product-minded software leader and founder with 11 years of experience building web platforms that turn training into revenue. Currently Head of Riseup Monetisation and founder of Yunoo, he focuses on integrating LMS, e-commerce and payments to help organizations monetize learning catalogs and shorten time-to-skill. His hands-on background spans full-stack development, growth engineering and headless CMS workflows from startups to scale-ups like Qonto and GitGuardian. David combines technical implementation (Rails, React, Flask) with growth-driven experimentation—A/B testing and conversion optimization—to align product, marketing and engineering. Based in London, he brings an uncommon mix of legal education, entrepreneurial grit and practical engineering that helps bridge business strategy and execution. Notably, he builds platforms that embed training commerce directly into customers’ existing toolchains rather than treating learning as a siloed product.
