Sourhouse
Sourhouse is a small Asheville company started by Erik Fabian and industrial designer Jennifer Yoko Olson, and it builds tools for one job: keeping fermentation warm and steady. Goldie, its countertop starter warmer, launched on Kickstarter in April 2022 and drew $103,948 from 1,007 backers, close to triple the $39,000 goal. A jar sits under a borosilicate glass dome and stays in the 75 to 82 F band the company calls the Goldilocks Zone; a cooling puck covers hot kitchens. DoughBed, a proofing bowl with a warming base, followed. Goldie won a Good Housekeeping kitchen gear award in 2024 and sells through Williams Sonoma.
The approach is plain hardware: one switch, no app, manuals in seven languages, one year limited warranty. Useful where the kitchen sits at 68 F and the starter crawls all winter. Bakers in warm climates, or people short on counter space and outlets, get less out of it.
