# Atmos

> Atmos was a San Francisco-based homebuilding marketplace that helped buyers in North Carolina find lots, design custom homes, and work with vetted local builders. Its design-led process paired online visualization with human project managers. Founder Nicholas Donahue said it built 50 houses and shut down around March 2025 as the work grew operationally heavy and higher interest rates squeezed buyers.
