The name says it all. Ctrl-S — the keyboard shortcut for save — is a new company doing exactly that for the direct air capture sector: saving the work before it’s lost.

Here’s the context. DAC investment has dropped more than 60% from its 2022 peak. The Trump administration cancelled tens of millions in federal DAC funding. Companies that raised on the 2021-2022 climate hype cycle are running out of runway, and when a deeptech startup dies, its IP, experimental data, and hard-won engineering knowledge often die with it. Papers in drawers. Lab notebooks in storage units. Sorbent formulations that took years to develop, gone.

Jason Hochman, who spent four years running the Direct Air Capture Coalition, saw this coming and founded Ctrl-S to do something about it.

A Knowledge Salvage Operation

The model is straightforward but clever. Ctrl-S acquires intellectual property, experimental data, and engineering knowledge from distressed DAC companies. It assembles these assets into a structured library that better-positioned companies can access through subscriptions, licensing fees, and royalties.

The founding team reads like a who’s-who of DAC institutional knowledge: Nicole Williams, former IP Lead at Climeworks, and Silvan Aeschlimann bring deep expertise in what’s actually protectable and valuable in this space. They’re not just hoarding patents — they’re diligencing every acquisition for technoeconomics, lifecycle analysis, and commercial potential.

Crucially, they distinguish between companies that failed because the tech didn’t work versus companies that failed because the market wasn’t ready, the funding dried up, or the team couldn’t execute. That distinction determines whether an asset is a cautionary tale or a shortcut.

The Negative Learnings Are the Real Gold

Here’s what caught my eye: Ctrl-S explicitly values “negative learnings” — the things that didn’t work. This matters enormously for the emerging field of AI-driven materials science. Machine learning models for discovering new sorbents, solvents, and contactors need training data, and knowing what fails is just as informative as knowing what succeeds. Every dead-end experiment a shuttered startup ran is a data point that could prevent another company from spending months on the same dead end.

There’s also a cross-industry angle. Components like air contactors and sorbent materials have applications beyond CO₂ capture — think hydrogen separation, industrial gas purification, even air quality. The IP library Ctrl-S is building could have value well beyond the DAC sector.

What This Tells Us About the Industry

When an industry starts building knowledge preservation infrastructure during a downturn, that’s a sign of maturation, not decline. The semiconductor industry did this. Biotech did this. It’s what happens when people who’ve been in the trenches decide the work is too important to lose, even when the money gets scared.

The DAC funding winter is real. But the technology didn’t stop working just because VCs got cautious and politicians got hostile. Ctrl-S is betting that when the market turns — and it will — the companies that can leapfrog failed experiments will move fastest.

Ctrl-S. Because the worst thing about a funding winter isn’t the companies that die — it’s the knowledge that dies with them.
