Summary
👤
Senior🎓
Top SchoolSean Geoghegan is a seasoned technology leader with 18 years’ experience who has scaled product, engineering and design teams from MVPs to multi-country organisations, most notably as CTO of Sendle for a decade. He blends pragmatic software architecture with business strategy, hiring and lightweight product processes that grow with scale-ups, and has hands-on credentials from early engineering work and notable open-source contributions to projects like capybara-webkit. Comfortable switching hats — including a stint as Chief People Officer during COVID — Sean excels at leading distributed, high-performing teams while preserving culture and fun under pressure. Now based in Adelaide, he mentors startups and founders, advises early-stage companies, and recently moved into platform leadership, bringing both founder-level grit and operational discipline. An underappreciated strength is his ability to turn deep technical fixes (memory management, authentication timeouts) into product-quality reliability improvements that pay off at scale.
