#241 Startup collapse to $21M a16z raise: Sphere's Nick Rudder on Aussie Grit in the US, Selling to CFOs and Superhero wife
The High Flyers Podcast with Vidit AgarwalShow Notes
Episode #241 features Nicholas Rudder, Founder & CEO of Sphere — which recently raised a US$21M Series A led by Andreessen Horowitz (a16z), to help some of the world’s fastest-growing companies, including Lovable, Linktree and Deel, navigate complex cross-border tax compliance using AI.
Nick shares the defining crucible of his journey: Growing up in Europe and Australia, then moving to the US chasing a dream, losing a co-founder, rebuilding as a solo founder, navigating a high-risk twin pregnancy that forced his family out of the US, and holding conviction when belief and momentum collapsed.
He breaks down how deep CFO discovery led to Sphere’s model of using AI as a junior analyst to interpret global tax rules, the magic behind zero-churn customer retention, motivating engineers and more— offering rare insight into building a durable company in a high-stakes, regulated industry.
