Stonebird Labs
Stonebird Labs builds focused Apple-platform software and small digital products under one long-term owner. The current product family is Breadcrumb for Mac, Gridlock: Terminal for iPhone, and Spend Scout for private iPhone expense tracking.
Stonebird Labs is operated by Stonebird Group as the product and software venture arm for focused digital products.
The portfolio favors narrow, useful products with clear privacy boundaries, simple distribution, and long-term ownership.
Current public product pages cover Breadcrumb, Gridlock: Terminal, and Spend Scout. Breadcrumb and Spend Scout remain pre-launch; Gridlock is live on the App Store.
