Mostly Harmless Ventures builds software that is useful, occasionally funny, and — as the name suggests — mostly harmless.

Specializing in AI-integrated applications, iOS and web development, and the art of turning improbable ideas into shipped products. The kind of operation that reads the spec, questions it, then builds something better.

Named for Earth's entry in the Hitchhiker's Guide to the Galaxy. A nod to the idea that simple, understated things can carry the most meaning.
