Ian is a systems engineer who spent ten years fixing fragile business infrastructure before founding Tessellium.
I’ve spent most of my engineering career working on backend architecture and database pipelines - the kind of invisible infrastructure that either works perfectly or breaks catastrophically.
Over the years, I noticed a painful pattern: as businesses scale, they rarely upgrade their underlying systems to match their growth. Instead, they turn their best, highest-paid staff into human middleware - forcing them to spend their weeks copying data between spreadsheets because their apps refuse to talk to each other.
I founded Tessellium to build a mature alternative. I don’t care about the latest AI hype or building flashy, fragile solutions. I care about building deterministic, boringly reliable data infrastructure that runs silently in the background, so business owners can stop acting like software plumbing.
