Building what
matters most
I founded and sold Lemonaid Health for $400M. Now I’m a General Partner and CEO of venture fund Flex Capital. I continue to coach CEOs, invest in exceptional founders, and write about the people shaping our future.
From a tiny UK village to Silicon Valley
I had a childhood dream of moving to Silicon Valley. I made that dream a reality in 2013, moving from the countryside in the UK to San Francisco in my 20s to found Lemonaid Health.
During an 8-year rollercoaster ride we raised over $60 million, recruited a team of nearly 200, and helped millions of patients access more convenient, more accessible healthcare. We sold Lemonaid for $400 million in November 2021 — over 10x our Series A price.
Since the sale, I’ve been advising leading venture funds, coaching founders and CEOs, writing books, and playing way too much pickleball.
I’m like a sports coach, but for CEOs
I help CEOs realize their vision and dramatically increase the likelihood of a successful business outcome. Even the very best athletes have a coach — CEOs should too.
Minor League Coach
Weekly 1:1 coaching on product, sales, marketing, and leadership. Plus on-demand support via message.
Premier League Coach
Everything in Tier One, plus a data-driven CEO training plan, quarterly peer group sessions, and advisory board participation.
