Substitute Goods Make Energy Hardware Easier to Underwrite Than Software

What's New

Energy and advanced manufacturing startups carry less market risk than consumer software because each product replaces a good that a known customer already buys at a known price. Chris Sacca, Co-Founder at Lowercarbon Capital, and Caie Kelley, General Partner at the firm, argue this in a conversation on Alt Goes Mainstream. Carbon is expensive to extract, move, and defend, so every decarbonized process starts with a cost advantage. What remains is technical and operational risk, which a lab visit and a supply chain review can test. Allocators should price these companies against the commodity they replace and reserve venture-style guesswork for the science.

Why It Matters

The argument inverts the standard view that hard tech is riskier than software because it needs factories and years of capital. Sacca's counter is that web rounds funded customer acquisition and hoped the model would work, while a transformer maker interviews its buyer before day one. Lowercarbon manages over $3 billion and gains if institutions reclassify "climate" as "energy." Project financiers who demand serial pilot projects before committing are the group on the other side.

By The Numbers

• 2 cents per kilowatt hour: Panthalassa's target electricity cost from ocean wave nodes. The founder gives himself four years. Most consumers pay 10 to 15 cents today.

• 10 or 11 portfolio companies now exceed $100 million in revenue, by Sacca's count.

• $600 million of run rate at Fuse Energy, the UK neo-utility. It took two and a half years.

• 5 to 7 years: the backlog for gas turbines, which Arbor attacks with a printed supercritical turbine the size of a coffee cup lid.

Memorable Quotes

• "It's cheating. We've seen the answer key to the test." Known buyers and known prices turn product-market fit from a guess into an interview.

• "We have a rule that we will never get into a permission-based business." Lowercarbon avoids fission and interconnect queues because a regulator's timeline is risk it cannot control.

• "A few years ago I didn't really realize we needed Kai and it wasn't a muscle we ever had within the org." Sacca admits his gut-based consumer web method could not re-underwrite a Series B hardware company.

• "It's the only time I've ever seen where doing well and doing good, the Venn is a complete overlap." The returns case and the impact case rest on the same cost advantage.

The Wrap

Sacca and Kelley describe Lowercarbon as an energy, advanced manufacturing, and resilience investor that avoids the climate label. They invest early on technical risk, then re-underwrite at growth with supply chain, pricing, and demand data that consumer web deals never produced. They refuse permission-based businesses, including fission, and favor fusion and decentralized generation because those depend on execution alone. Both see the next phase in moving these companies from equity to project finance, and Sacca expects outside bids to confirm their entries roughly five years after each deal.
