About Tangible
The world is rewiring itself. Reshoring of manufacturing. Securing energy supply. Racing for compute dominance. Fighting labor shortages with automation.
It's creating the largest capital reallocation in decades. A hard asset supercycle. Trillions in batteries, data centers, solar farms, robotics, heat pumps, and manufacturing infrastructure that need to get built, and built fast. These companies will be majority funded by debt, but accessing the kind of structured finance vehicles they need is still a nightmare of spreadsheets, inflated costs, complexity and mystery all wrapped up in year-long timelines.
That's why we're building Tangible. We make raising and managing asset-backed financing as efficient and intelligent as the hardware these companies are deploying.
We are a small and nimble team, passionate about seeing these hardtech companies succeed. The company has 3 co-founders with a mix of product, technology and capital markets expertise. You can find out more about our thesis here.
