The story behind Proof

Built by a baker,
for bakers.

Proof was created by Diana Banisor — sourdough baker, iOS developer, and founder of Roots & Tails LLC, born in Romania and currently based in New York. What started as frustration with store-bought bread, slowly turned into a passion for making it from scratch: wholesome, nourishing, and fun to experiment with. Nothing compares to the smell of freshly baked bread.

Proof is a sourdough app for bakers who want more than guesswork. It helps you log, track, calculate, and understand your bakes so you can build consistency, confidence, and better bread over time.
