Hesiod Holdings
A lab building AI tools for the built world.
The models are finally good enough
to do real engineering and regulatory work.
The question is no longer whether AI can. It's who has the domain expertise to point it at the right problems — and the standing in the industry to sell the result.
The built world runs on judgment that lives in the heads of engineers, the files of permitting agencies, and the routines of contractors. That knowledge has never been software's to capture. Until now.
Every project passes through the same slow, expensive, human layer.
Land gets bought on incomplete information. Design is bespoke and manual. Permitting and compliance are paper, email, and software from a generation ago. Geotechnical and civil analysis is billed by the hour.
Each step is a toll booth of human judgment — and each is now addressable by AI in the hands of people who have actually sat in those chairs. We build at every one of them.
One lab. A product at every level of the AEC stack.
Each tool is a business. Together they're a pipeline.
The same tools sell at every altitude of the market.
One engine, three price points — plus the highest-value customer of all: ourselves.
Shipped, not slideware.
Built lean, in public, from inside the industry.
We become our own best customer.
Capital lets us stop renting our own thesis and start owning it — running the whole pipeline on real assets we control:
Every cycle proves the software, throws off real-asset gains, and feeds product back into the tools we then sell to everyone else. The flywheel funds itself.
Civil engineers and builders who also ship software.
We've sat at the permit desk, run the projects, and stamped the work. We know exactly where the judgment lives, where the money leaks, and which corners cannot be cut.
That pairing — deep AEC domain expertise with models that are finally capable — is rare, and it's ours. Most AI teams don't understand this industry. Most of this industry can't build. We do both.
Raising a pre-seed round to run the flywheel.
Target raise and terms shared under NDA. Introductions welcome.
Build the built world with us.
