Eoin Hayes

ex-Palantir, 3 SLTs, 1 exit

I've spent 10+ years working in and with world-class CEOs and founders from seed to Series B on building their companies, specialising in FP&A and financial transformation in preparation for fundraising or exit for B2B or B2E startups in healthtech, fintech, and climatetech.

I previously worked on the Strategy team at Palantir Technologies, was an intern at Google, and led FP&A and Special Projects at the fintech unicorn, Wayflyer. In a past life, I was a management consultant in NYC and a chemical engineer for Pfizer. I'm a graduate of London Business School.

I'm deeply passionate about helping founders win, and I enjoy hiking and raising money for charity in my spare time!
