Portrait of Ashley Grealish

Ashley Grealish

Hi, I’m Ashley, co-founder and CEO of Windfall Energy. While the clean energy transition is accelerating, I noticed that most solutions exclude the millions living in flats and rented homes. That’s why I’m building Windfall Energy - to create affordable, installation-free home batteries that work for everyone.
