Danny Mayer is the co-founder and co-CEO of Windmill, the design-led air care company often called 'the iPhone of air conditioning.' A Harvard economics grad who spent a decade in investment banking, private equity and health-tech leadership, he teamed up with his brother Mike and third-generation AC expert Ryan Figlia in 2020 to reinvent the unloved window air conditioner. Windmill launched to thousands of waitlist sign-ups within 24 hours and has since expanded into air purifiers, fans and a connected smart-air suite, raising a $5M Series A in 2024.
Windmill
Windmill is a New York-based modern air care brand that redesigned the window air conditioner - and the unglamorous category around it - into sleek, app-connected, energy-efficient products. Founded by brothers Mike and Danny Mayer with third-generation AC expert Ryan Figlia, the company has expanded from a single quiet window unit into a full suite of air care: ACs, medical-grade HEPA air purifiers, fans, and subscription central air filters. With over 100,000 ACs sold and shelf space in Home Depot, Best Buy, and Lowe's, Windmill is betting that clean, comfortable air should look good and feel effortless.
