Shadow Foundry innovates and invests in revolutionary technologies.


Shadow Foundry provides technical expertise and pre-seed funding to startups. Pre-seed funding happens at the idea stage, often before you have incorporated. Our technical expertise helps you get to a customer-ready version 1.0 of your product.

At Shadow Foundry, our mission is to change the world by de-risking revolutionary technologies. To do that, we provide substantial funding for relatively small stakes. (We neither request nor demand board seats.) For founding teams with technical needs, we embed ourselves as an interim tech lead — testing new ideas, writing code, and engineering — for as long as you need while you recruit permanent staff.

We are an activist venture firm and prefer to work intensively with every startup in our portfolio. As such, we currently choose to limit our focus to just a handful of core investments each year. We believe the most promising projects are substantially improved with our quality time and attention, and so we do not entertain ideas that are not moonshots.

As part of our commitment to de-risking innovation, Shadow Foundry allocates a substantial portion of its portfolio towards capturing supererogatory asymmetry, a special situation where risk/reward calculations approach complex infinity. As a result, our portfolio may reflect an asset diversity uncorrelated with any other venture or investment firm.
