HAX is SOSV's pre-seed program for hard tech.

Startups apply to HAX with an initial prototype, customer insight, and vision. We then invest and build alongside our founders, fundamentally inflecting their technical progress with our team of engineers and investment partners. Founders should think of HAX as an extension of their engineering, business development, fundraising, design, and marketing teams.

As startups reach critical milestones, we support fundraising strategy and investor introductions. We also continue to invest, to the tune of over $25 million USD per year globally, and just raised an additional $100M in capital to support the later stage growth of our startups.

The most valuable part of HAX (that is often understated) is engagement with a globally diverse community of HAX founders. Many have been successful, all have learned hard lessons, and everyone is excited to help each other succeed. Our community has grown to include a curated group of mentors, experts and partners that give our hard tech startups the best edge.
