Investment thesis

Riot Ventures is a deep-technology venture capital firm dedicated to modernizing critical industries through advanced technology solutions. Founded in 2017, the firm focuses on early-to-growth stage companies that apply cutting-edge technology—including AI, robotics, advanced computing, and hardware innovation—to solve problems in traditionally underserved sectors. With a mission to deploy capital where venture funding is scarce relative to the opportunity, Riot targets industries like aerospace, defense, manufacturing, energy, logistics, and industrial automation. The firm's thesis emphasizes 'defiant voices' building transformative solutions in physical industries. Rather than competing with the influx of capital in software and consumer tech, Riot deliberately targets sectors that receive minimal venture funding but face enormous modernization opportunities. The firm positions itself as a partnership vehicle—not just a source of capital—providing deep operational support, strategic guidance, and access to their extensive network of entrepreneurs, engineers, and industry experts. From its early-stage fund, Riot leads or co-leads 6–8 new institutional seed rounds per year with initial check sizes ranging from $1.5M–$5.0M, and from its growth platform makes 2–4 investments per year with check sizes ranging from $25M–$50M.

Notable quotes

We believe we're at the very early innings of a very dramatic transformation across critical industrial sectors.

Building a generation of companies the size of SpaceX, Tesla, and Nvidia will require the industry at large to participate.

There was not a lot of innovation capital going towards these monster sort of industrial sectors of the economy: manufacturing, construction, defense and aerospace, supply chain logistics, energy.
