Hey Product Hunt 👋 I'm Dave — a quantity surveyor with 26 years in construction. Here's why I built this. Construction is project-centric in a way most industries aren't. The team that delivers a building is assembled specifically for that project — architect, structural engineer, main contractor, specialist trades, client-side project manager — and when it's done, they all go their separate ways. Most of them never worked for the same company. Most of them never will again. But they built something together that is still standing. The problem is that nowhere captures this properly. LinkedIn shows who you worked for. It doesn't show what you built or who you built it with. A self-reported project list carries no weight because anyone can claim anything. The deeper idea behind Hanga is that a single building brings together dozens of teams and hundreds of people who mostly never knew each other existed. The M&E contractor didn't know the landscape architect. The piling subcontractor never met the interior designer. But they all contributed to the same thing. Hanga lets all of them claim their piece of it — and lets their former teammates verify it. Your career in construction isn't really a list of employers. It's a map of buildings. The companies you worked for are secondary to what you actually delivered. I built Hanga because that tool didn't exist. And with AI assistance it turned out I could build it myself — which felt like its own experiment worth running. Would love your honest feedback — especially from anyone in the built environment who has felt this problem personally.
