Summary
April co-founder and CEO Ben Borodach joins Fund/Build/Scale to break down how he built a compound startup in one of the hardest markets in fintech: U.S. taxes. We talk about why some problems can’t be solved with a simple wedge product, how to sequence engineering, compliance, and distribution, and what it takes to operate inside complexity for years before the market catches up. Ben shares the early customer discovery work, the “science experiments” that shaped April’s product, and the cultural frameworks he and his co-founder developed before they wrote any code. If you’re an early-stage founder deciding what to build — or how to build it — this episode offers a clear playbook for choosing hard problems and de-risking them the right way.
