Today on BILLIONS, I’m sitting down with Arthur Waller, one of the sharpest French founders of his generation.

He sold his first company to Booking.com in his twenties — and instead of retiring, he came back to build Pennylane, a fintech that turned accountants from enemies into growth partners and became one of europe fastest-growing unicorn.

In this episode, we will discuss how six co-founders actually share power, what founders get wrong about fundraising terms and dilution, and what Arthur thinks about secondaries, freedom, and building a company that lasts twenty years.

If you want to understand what it really takes to scale, cash-out without selling out, and keep your ambition alive after success - then this episode is for you!
