For decades, science has been something you could only observe from the outside. You waited for institutions to test, publish, and decide what was true. But the internet changed that.

Today, millions of people are running small experiments every day. They test peptides, supplements, and sleep routines. They track blood markers, share results, and help each other learn. The tools for discovery are already in their hands — what’s missing is the system that makes those discoveries count.

Signal exists to turn this informal movement into something that lasts.

It takes the raw curiosity of self-experimentation and gives it structure, verification, and permanence. Every experiment can become a small piece of science — validated, recorded, and connected to others.

The idea is simple: when people can prove their progress, they can also build on each other’s results.

Instead of a thousand isolated tests, you get a growing map of what actually improves human health and performance.

Signal isn’t trying to replace science. It’s making space for a new kind of it — open, continuous, and driven by the people doing the work.
