He Bet His Career on a "Boring" $100 Trillion Problem — Duncan Barrigan

What do you do when the most important problem you can solve is also the least glamorous one?Duncan Barrigan spent 8 years helping build GoCardless into a global payments unicorn — then walked away to tackle something most founders walk right past: getting businesses paid. Not sexy. Not shiny. Just a $100 trillion problem that's been solved the same way, by humans, for 6,000 years.In this conversation, Duncan breaks down why accounts receivable is actually a communication and negotiation problem (not a payments problem), how he brought a real cowboy and horse to lasso the Wall Street Bull for Lunos' launch, and what it really means to build a company around three values: curious, courageous, and relentless.We also get into the identity shift that hit when he left a CXO role at a billion-dollar company, moved to New York in January, and had to rediscover who he was before Lunos existed.If you're a founder choosing between the bold idea and the safe one — this one's for you.——TIMESTAMPS0:00 — Cold open: the horse that got stopped at the Manhattan border0:23 — Introducing Duncan Barrigan & Lunos1:48 — Lunos or Lunos?
