## Questions

### Who runs investment decisions at HAX?

HAX is led by General Partners including Cyril Ebersweiler (co-founder), Duncan Turner, and Garrett Winther. The firm operates as part of the SOSV network but makes independent investment decisions for its accelerator and venture programs (per TechCrunch, 2022).

### How does HAX's investment model differ from traditional venture capital?

HAX combines an accelerator structure with venture capital. It provides small initial checks ($250,000 to $500,000) plus intensive engineering mentorship and supply-chain support, particularly through its Shenzhen office. The firm then often participates in follow-on rounds, providing additional capital as portfolio companies scale (per TechCrunch, 2022).

### Which sectors does HAX explicitly invest in?

HAX focuses on hard tech, including robotics, medical devices, industrial automation, sensors, climate technology, and bioengineering. It avoids pure software, fintech, and service-based models (per TechCrunch, 2019).

### How does HAX source proprietary deal flow?

HAX draws deal flow through its physical accelerator program and reputation in hard tech. It also leverages its network of portfolio founders, partnerships with Shenzhen's manufacturing community, and its Climate Tech Summit. It often attracts deep-tech founders who need engineering and supply-chain help (per TechCrunch, 2022).
