We build from problems we’ve lived.To help as many people as we can. Guided by service and made with joyisness, curiosity, and gratitude.
We start with problems we’ve felt ourselves and build the tools we wish had existed.
Every product should help someone live with a little more clarity, confidence, or connection.
We make because creating is worthwhile. Sustainability matters, but profit is never the whole point.
Caleb Kawano
Founder / Builder
Caleb is an Applied Mathematics student at UC Berkeley building focused tools for needs he knows firsthand.
Variance began with a simple question during quant interview prep: why can’t this practice fit into the five minutes you already have? Bread grew from the desire to stay consistent in Scripture. pAIr is being built to make shared groceries and meal planning feel lighter for real households.
