LOUISVILLE, Ky. — March 25, 2025 — GE Appliances’ innovation arm FirstBuild and King Arthur Baking Company have introduced a new countertop device designed to automate one of sourdough baking’s most time-intensive tasks: maintaining a starter. The product, called the Sourdough Sidekick, is now available for pre-order through a crowdfunding campaign, with shipments المتوقع to begin in early 2026.
The launch reflects growing consumer demand for sourdough baking tools, as more home bakers seek convenience without sacrificing quality. According to King Arthur Baking data, 60% of bread bakers now maintain an active starter, underscoring the rising popularity—and complexity—of naturally leavened bread.
The Sourdough Sidekick is engineered to automate feeding schedules and maintain starter consistency, addressing a key barrier for both novice and experienced bakers. By integrating sensors and programmable controls, the device aims to reduce daily maintenance while improving reliability.
“By listening to our customers and collaborating with enthusiasts, we are innovating the future of what’s next for the home.”
Kevin Nolan, CEO, GE Appliances
Automating a traditionally manual process
Sourdough starters require regular feeding with flour and water, often daily, to remain active. Missed feedings can compromise fermentation and flavor, making consistency a challenge for many home bakers.
The Sidekick’s “Auto” mode allows users to specify how much starter is needed and when, down to the hour. The system then manages feeding cycles automatically, eliminating the need for discard for up to seven days. A “Custom” mode provides flexibility for advanced users who want to maintain specific ratios or schedules.
The device also includes temperature sensing technology, adjusting feeding intervals based on environmental conditions. It is designed to work with a branded glass crock developed in collaboration with King Arthur Baking Company.
Strategic collaboration and innovation pipeline
The partnership brings together FirstBuild’s rapid prototyping model and King Arthur’s longstanding expertise in baking. Founded in 1790, King Arthur Baking Company contributes more than two centuries of knowledge to the project, while FirstBuild leverages community-driven product development.
FirstBuild has previously launched successful small appliances, including the Opal Nugget Ice Maker and the GE Profile Smart Indoor Smoker. These products have played a role in GE Appliances’ broader push back into the small appliance category.
Executives from both companies emphasized the role of consumer feedback in shaping the product. The development process incorporated insights from baking enthusiasts, aligning with FirstBuild’s co-creation model.
Market demand and consumer trends
The rise in sourdough baking has been fueled by increased interest in artisanal and homemade foods. King Arthur Baking reported millions of views on its sourdough-related content, with starter recipes ranking among its most popular resources.
