Peter Holt represents the fifth generation of the Holt family that created the original Caterpillar track-type tractor and currently serves as CEO of HOLT CAT, the largest Caterpillar dealer in the U.S., while also co-founding Ironspring Ventures. He built the Ironspring Network from an operator base in 2017 as an invite-only group of industrial operators to bridge startups with heavy-industry incumbents, giving him a rare ability to get portfolio companies into OEMs and supply-chain players quickly.

Notable Investments
Ironspring Ventures is a venture capital fund purpose-built around "digital industrial" innovation, focusing exclusively on modernizing legacy industrial sectors like construction, manufacturing, transport & logistics, and alternative energy, with every GP having spent their entire career inside industrial environments before launching the fund. The firm deliberately targets the "missing middle" round in industrial tech—typically leading or co-leading post-seed/Series A checks of $2–4M into ~$7–10M rounds—and uses a highly curated industrial operator network as an explicit go-to-market "superpower" to immediately open doors to global OEMs, industrial contractors, and supply-chain incumbents.
