How One CTO Uses Internal Platforms to Kill the Build vs Buy Trap

Every engineering leader eventually faces the build-versus-buy decision. In this episode, Lucas and Luna unpack a concrete case: a mid-stage fintech CTO who set up a lightweight internal platform team that turned the build-versus-buy question on its head. Instead of choosing between buying an off-the-shelf vendor product or building a custom solution from scratch, the team built a reusable internal component that served three different product teams. By measuring cycle time and developer satisfaction before and after, they found a 40% reduction in time-to-ship for new features and a 30-point jump in developer NPS. Lucas walks through how the CTO convinced the board, what the platform actually looked like, and why this approach avoids the classic pitfall of building everything in-house. Luna pushes back on when this doesn't make sense and adds a counterexample from a legacy enterprise that failed with a similar strategy. The episode closes with the hosts reflecting on how to know if your org is ready for internal platforms — and a quick note on how listener support keeps Fexingo ad-free. #BuildVsBuy #InternalPlatform #PlatformTeam #DeveloperExperience #CTO #Fintech #TechLeadership #CycleTime #DeveloperNPS #EngineeringManagement #ReusableComponents #ProductTeams #LeanEngineering #OrgDesign #Technology #FexingoBusiness #BusinessPodcast #TechPodcast Keep every episode free: buymeacoffee.com/fexingo
