Software House Services, Explained
What a Software House Does
A software house designs and builds custom software for a business: apps, web platforms, internal systems and the integrations between them. The difference between software houses is how they decide what to build, and whether the people who designed it are the ones who build it.
How We Are Different
Most software houses build from a specification. We start one step earlier: research with the people who will use the software, then flows and prototypes tested with them, then development by the same team. What we test is what ships.
