The name comes from சிந்தை (sinthai) — Tamil for "mind and thought." Our logo is the sigmoid function σ(x), the curve at the heart of neural computation: the moment a signal becomes a decision. That's the standard we hold our products to — technology that helps people think and decide better.
The tools and experiments behind our products — free for anyone to use, learn from, and build on.
