Long partnerships
The second project is worth more than the first
The second project with a team is worth more than the first, because the context is already there. Your conventions, your tech quirks and your people are the ground we built the last release on, and none of that has to be relearned from scratch.
We prefer to build relationships that way: a first piece of work scoped tightly enough to be low risk, then a longer arrangement if it goes well. It is a slower way to win work and a better way to do it. Nothing asks a partner to bet on us before we have earned it.
