I’ve explored different aspects of product-market fit on the podcast, but when you’re scaling an open-source business with enterprise customers and a global developer community, you also need customer–engineering fit — the ability to translate between what’s being built and what the market actually needs.
At Astronomer, Viraj Parekh is that bridge. He is part engineer, part strategist, and part customer advocate, working across product, sales, and engineering.
In this episode of Fund/Build/Scale, Viraj explains what a Field CTO really does, how the role evolved at Astronomer, and when founders should consider creating one. He also shares lessons on customer discovery, team dynamics, and how to turn technical insight into business momentum.
