Leaf Suit (YC W20)

We make a lightweight, USB-powered, air-conditioned vest that keeps people 20 °F cooler. Our product improves worker safety, dramatically increases productivity and reduces accident rates. Our vision is personalized cooling as a treatment and solution to a warming planet. Cooling already consumes 10% of global electricity and cooling needs are set to triple by 2050. Leaf Suit is 100x more efficient than traditional air-conditioning and it offers controllable cooling even when outdoors. Cooling is absolutely critical to global health and productivity. We’re trying to build a future where people are always kept at whatever temperature they want, wherever they want. We’re trying to build a cooler future for everyone.
