To expand on Paul’s answer…
Ed is the manager of the whole of Steinberg’s support team, and he’s based in Hamburg. We are planning to have one or two dedicated Dorico support people based in Hamburg with Ed and the rest of his team covering English- and German-language support.
We have seven developers working on Dorico: Paul, James, Graham, Michael, and Andrew all previously worked on Sibelius for many years; András and Stefan joined us about two years ago (and Stefan is the husband of somebody who also used to work with us back in the Sibelius days).
We have three software testers, though that rather pedestrian title belies the true impact they really have on our project, which is profound in many dimensions: Richard (who leads the team), Toshi, and Akiko.
There are four of us who have the word “manager” in our titles along with various other combinations of words: there’s me, there’s Ben, who heads up the team and in addition to taking care of all logistical issues also writes internal tools to help us work smarter (he’s been invaluable in developing SMuFL and our ongoing work on instrument data), there’s Anthony (who is responsible for the beautiful look of Dorico), and there’s Bill, who is our agile team leader (runs the development process) and is also doing some development work on Dorico.
So there are fourteen of us here in London, and of course we all rely on the support and expertise of all of our colleagues in Hamburg.
