Sigma Stack is a one-person app studio. Every product here — the idea, the design, the code, the launch, and the support inbox — is handled by the same pair of hands. That isn't a limitation; it's the whole point. No handoffs means nothing gets lost between what users ask for and what ships.

The studio's name is its philosophy: sigma is the sum. Each shipped app is one layer, and the stack is what they add up to. Products are kept deliberately small in scope, priced honestly, and improved in weekly releases rather than yearly rewrites.

There are several apps in the works right now — spanning AI, personal finance, productivity, and games. They’ll show up here as each one ships.
