Radius

Radius works in payment processing, which is about accepting cards, bank transfers and wallets online or in person. They have not published a longer description, so we lean on what their category usually involves.

It makes the most sense for any business that takes money. Alongside the main category they mention Agentic AI, AI Infrastructure, Artificial Intelligence (AI), Blockchain and Infrastructure.

Radius is based in Cambridge, Massachusetts. More on radiustech.xyz.

Before you commit, look at rates, payout timing, chargeback handling, and developer tools. Get the renewal terms in writing before the first invoice.

If you have worked with Radius, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
