In this episode of Tech Startups with Fexingo, Lucas and Luna dive into the story of Paddle, the London-based fintech that built a complete revenue infrastructure for SaaS companies. They explore how Paddle started as a simple checkout solution, evolved into a full revenue delivery platform handling taxes, compliance, and subscriptions, and recently became a public company. Key numbers include Paddle handling over $3 billion in payment volume annually and serving 5,000+ software businesses. The hosts discuss the challenges of global sales tax compliance, the shift from merchant of record to integrated revenue platform, and how Paddle competes with Stripe and Chargebee. Listeners learn why SaaS founders are increasingly outsourcing their billing stack and what Paddle's IPO signals for the B2B fintech landscape.
