# Sudip Mukhopadhyay

> Sudip Mukhopadhyay is the CEO and co-founder of AirMyne, a Berkeley-based climate-tech company building liquid-solvent Direct Air Capture (DAC) machines that pull carbon dioxide straight out of the sky. A chemist and engineer with more than two decades in industrial R&D, he co-invented the low-global-warming car refrigerant 1234yf during a 16-year run at Honeywell, where he rose from engineer to corporate fellow and director of innovation. He launched AirMyne in 2022 with co-founder Mark Cyffka through Y Combinator, raising $6.9M in seed funding and a strategic investment from Japanese energy giant ENEOS, with the bet that cheap low-temperature heat (including geothermal) can make carbon removal affordable at industrial scale.
