The lessons from building and scaling a startup from idea to finding customers to creating repeatable revenue.
Over eight years at HubSpot, I helped shape its go-to-market strategy as the company evolved from a single application into a global platform, growing from millions to billions in annual revenue.
Today, I lead end-to-end GTM at one of the world’s fastest-growing software and AI companies.

“I’ve taken what I’ve learned from doing this and built it into a system that helps businesses make better GTM decisions without unnecessary complexity.”
People we’ve helped.
“I have worked with several mentors over the years, but Eoin stands out because his advice is grounded in real-world experience rather than generic frameworks or theory. Every conversation leaves you with practical actions that you can implement immediately. His go-to-market strategy and customer discovery guidance had an immediate impact on CENTUMX. Ahead of VivaTech, his preparation and advice were invaluable. He encouraged us to focus on enjoying the experience while making the most of every conversation, and he was absolutely right. We came away with meaningful industry discussions, valuable market insights, and a much clearer direction for our growth in the leisure sector. If you're looking for someone who combines strategic thinking with practical execution and genuinely cares about helping founders succeed, I couldn't recommend Eoin more highly.”

“I've had the privilege of working with Eoin McGuinness through his involvement in Startup Wise Guys' Founders Club, where he leads our Customer Discovery workshops. These sessions are consistently among the most impactful in the program: not just because of the content, but because of Eoin's delivery. He's the kind of speaker who blends sharp insight with humour, energy, and total honesty. He doesn't sugarcoat, and that's exactly why founders love him. His sessions challenge assumptions, provoke meaningful thinking, and often create real 'aha' moments that stick with participants long after. If you're looking for a speaker who energises a room and delivers lasting impact, Eoin is that rare 1-in-a-million kind of voice every startup should hear.”
