moving fast to raise capital and address the biggest global challenges

“Hard Tech” means engineering or scientific breakthroughs in the physical world. In the startup world, that includes companies building new robotics, sensors, connectivity, electronics, critical materials, industrial processes, and infrastructure to unlock the massive opportunities for a sustainable global economy. Most of HAX’s founders come from backgrounds in science and technology, frequently straight from university programs. They join HAX deeply convinced that their idea can change the world, and they see HAX as the fastest path to build what will attract top tier, early stage venture capital – investment rounds joined by HAX’s fund, SOSV.
