Hertha Metals raised a $133.65M Series A for an iron plant. The most interesting investor is not a VC.
$65M of the round is equity from the U.S. Government, through the Industrial Base Analysis and Sustainment program. Khosla Ventures and Doerr Capital co-led. Toyota Ventures and Siemens Financial Services are in too.
The plant is called Chalyx, in Conroe, Texas. It targets 10,000 tons a year of high-purity iron for steel and magnets. The U.S. imports almost all of that iron today. Hertha claims its single-step process cuts costs by 25% against the blast furnace route. That is a company claim, not an audited number.
Here's the thing. Most people read this as a green steel story. I read it as a customer story.
Government as equity holder means a buyer with a reason to want the plant to exist. Toyota and Siemens are potential offtakers sitting on the cap table. Demand risk, the thing that kills most industrial startups, is partly priced in before the first ton is made.
Software founders get rounds by showing growth. Hard-asset founders get them by showing who is obligated to buy.
If you are raising for a physical business, look at your cap table. Does it contain anyone who will actually need your output?
Who on your list of investors is also a future customer?
