That effort, Atmos, went through Y Combinator, raised $20 million from investors like Khosla Ventures and Sam Altman, and tried to use tech to streamline the custom home design process. It had designers on staff who worked with clients while software handled the back-end. It grew to 40 people and $7 million in revenue, and they designed $200 million worth of houses, and built 50.

All that sounds great until you hear Donahue describe it. “It became this extremely operational business,” he told me on a Zoom call last week. “Kind of like a glamorized architecture firm.”
