The San Francisco-based startup has developed software and a marketplace that connects homeowners that want an ADU with contractors who can build them. Since it helps homeowners with architecture, design and permitting, the projects are essentially ready to go for contractors, the company says. So far, it has completed “hundreds” of projects and expanded from the Bay Area to Los Angeles, where the company achieved market level profitability in four months’ time, according to Czarnecki. The startup plans to soon launch in San Diego as well and then another five to six markets over the next year.“These are relatively small homes but they have a pretty interesting impact on the housing supply,” Czarnecki said. 1Sharpe Ventures, DivcoWest Ventures and existing investors Susa Ventures and Base10 Partners also participated in the financing, which brings the company’s total raised to just over $20 million.The company plans to use the new capital in part to increase its headcount from 30 to 50 or 60 by year’s end.

Meanwhile, Austin-based Kiro Action is a bootstrapped startup that is set to deliver “hundreds” of its structures, which the company describes as “modern refuge, crisis response housing & consumer dwellings deployed in hours.”Mighty Buildings lands $22M to create ‘sustainable and affordable’ 3D-printed homes By digitizing the design-build process, Cottage says it saves homeowners months of time and thousands of dollars, while providing its contractors a “predictable pipeline of projects and time-saving tools.” “ Cottage is one such company. “The complexity of the process, the opaque pricing and the difficulty of finding the right contractor was the inspiration for Cottage.”Czarnecki emphasizes that Cottage is not a prefab homebuilder.
