A London studio for businesses that take software seriously
We started Rossco Apps because too many good companies were running on bad software — templated websites, off-the-shelf systems bent out of shape, and agencies that vanished after launch.

Nine years of shipping software that stays shipped
We've delivered over 120 products across construction, healthcare, retail, finance and renewables — from three-week marketing sites to multi-year platform programmes.
Our team spans product strategy, UI/UX design, mobile and web engineering, AI, and cloud infrastructure. Every engagement gets a named project manager, a dated milestone plan and a fixed price agreed before a line of code is written.
We are deliberately selective about the number of projects we run at once. It keeps senior people on the work and it's the reason clients stay with us for years rather than launches.
Four principles we don't compromise on
Commercial before technical
We start with the number you're trying to move, then choose the technology. Never the other way round.
Small teams, senior people
The people who scope your project are the people who build it. No handover to a junior bench.
Ship early, then improve
You get a working environment in week two and every sprint after, so feedback happens while it's cheap.
Own your platform
You own the code, the accounts and the infrastructure. We earn the retainer, we don't lock you into it.
