    How Plaid Built the Financial Data API That Powers Fintech
    Jun 24 2026
    In this episode, Lucas and Luna explore how Plaid became the invisible backbone of modern fintech. Starting with a single number—$5 billion valuation at its 2018 funding round—they trace Plaid's journey from a Yale dorm room project to powering connections for over 12,000 financial institutions and apps like Venmo, Coinbase, and Betterment. Lucas breaks down the technical challenge of screen-scraping bank portals, Plaid's pivot to a cleaner API model with tokenized access, and the controversial 2020 acquisition by Visa that was blocked by the DOJ. Luna probes the tension between open banking regulation and consumer data privacy, and the hosts debate whether Plaid can maintain its dominance as competitors like MX and Finicity gain ground. Along the way, they discuss how Plaid navigated the 2023 banking crisis and why its 'developer-first' culture remains its strongest moat. A concrete look at the company that quietly enables your bank-to-app connection. #Plaid #Fintech #OpenBanking #API #Business #Technology #Startup #FinancialData #Venmo #Coinbase #Betterment #Visa #MX #Finicity #DeveloperFirst #Banking #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

  • How Supabase Is Building an Open Source Firebase Alternative

    How Supabase Is Building an Open Source Firebase Alternative
    Jun 24 2026
    Episode 71 explores how Supabase has grown from a 2020 open-source side project into a $2 billion valuation company challenging Firebase on its own turf. Lucas and Luna break down Supabase's unique business model: giving away the core product for free while charging enterprises for managed hosting, compliance, and row-level security. They dig into the company's traction — 4 million registered users, 3 million databases created — and how CEO Copple's bet on PostgreSQL over proprietary infrastructure is reshaping the backend-as-a-service market. The episode also covers Supabase's controversial 'license change moment' in 2024, when it forked the pg_graphql extension and added a 'FOSS exception' clause, and what that means for open-source trust. Specific numbers, real tension, no hype. #Supabase #FirebaseAlternative #BackendAsAService #OpenSource #PostgreSQL #PaulCopple #DatabaseInfrastructure #DeveloperTools #StartupFunding #BusinessModel #EnterpriseSaaS #LicenseChange #RowLevelSecurity #FOSSDrama #BaaS #VCSeries #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

    How Stripe Is Winning the Payment Infrastructure War
    Jun 23 2026
    Stripe processes over a trillion dollars in payments annually and powers millions of businesses. But its real moat isn't just checkout buttons—it's the financial infrastructure layer it's building underneath. In this episode, Lucas and Luna break down how Stripe evolved from a seven-line integration to a platform handling lending, treasury, and identity verification. They discuss the company's product expansion strategy, how it beats legacy processors like FIS and Fiserv, and why its biggest threat may not be a rival but a regulatory shift. If you run a SaaS company or work in fintech, this episode explains why Stripe is becoming the operating system for internet commerce. #Stripe #PaymentProcessing #Fintech #Startups #SaaS #Infrastructure #Business #Technology #FexingoBusiness #BusinessPodcast #TechTrends #APIs #Entrepreneurship #VentureCapital #DigitalPayments #Software #PlatformStrategy #DeveloperTools Keep every episode free: buymeacoffee.com/fexingo

    How Vercel Changed the Way We Build for the Web
    Jun 23 2026
    In this episode of Tech Startups with Fexingo, Lucas and Luna explore how Vercel built a front-end cloud platform that hundreds of thousands of developers rely on daily. They trace Vercel's origin as the company behind Next.js, the React framework that powers everything from small personal sites to major e-commerce storefronts. The conversation drills into Vercel's unique developer experience-focused business model, its edge network that makes sites load fast globally, and how it monetizes through a free tier plus team and enterprise plans. Lucas explains why Vercel's bet on the Jamstack architecture and serverless functions resonated with developers tired of managing infrastructure, and Luna questions whether the company can maintain its growth as cloud giants like AWS, Google, and Microsoft offer competing services. They also touch on the company's $2.5 billion valuation and its role in shaping the modern front-end ecosystem. A concrete look at how one startup built a business around making developers' lives easier. #Vercel #NextJS #WebDevelopment #FrontEndCloud #Jamstack #Serverless #DeveloperTools #StartupBusinessModel #EdgeComputing #FreeTierStrategy #GuillermoRauch #OpenSourceMonetization #FexingoBusiness #BusinessPodcast #TechStartups #Founders #Funding #SoftwareCompanies Keep every episode free: buymeacoffee.com/fexingo

    In this episode of Tech Startups with Fexingo, Lucas and Luna dive into how Anthropic built Claude to win enterprise trust—specifically in regulated industries like banking and healthcare. They break down the three architectural decisions that made Claude different: constitutional AI for safety, interpretability research for auditability, and a batch-processing API that meets compliance requirements. Luna presses on whether this is enough to compete with OpenAI and Google, and Lucas walks through the specific use cases where Claude is winning deals at JPMorgan, Bridgewater, and Palantir.
