Websites, Android apps, backends, cloud platforms and design systems that drive growth.

We design, build and run websites, Android apps, backends and cloud infrastructure for growing businesses. One team takes you from the first sketch to launch, and keeps it running after.

Built with modern, proven technology

One system, wired end to end

Your website and app talk to one API, backed by your data and the cloud, with testing and security under all of it. Point at any part to trace its connections.

Services

Six things we do, and do really well

From the first screen a customer sees to the server that answers at 2 am, one team takes responsibility for all of it.

All services

Same four problems. A different outcome.

Software projects tend to go wrong in the same few ways. Here is what we do about each one, and it goes into your proposal in writing.

  1. Usually

    The price grows and the date slips.

    Scope, price and dates fixed in writing.

    Before work starts you get a proposal with the first release, a price for each milestone and a date for each one.

  2. Usually

    Months of silence, then a surprise.

    A working demo every Friday.

    A preview link with real progress on it. You comment on the software, not on a slide.

  3. Usually

    The agency keeps the keys.

    Your code and accounts, from day one.

    Repository, hosting, domain and Play account belong to you. Leaving us never means starting again.

  4. Usually

    You are sold more than you need.

    Honest advice, even when it costs us.

    If a template, an off-the-shelf tool or a smaller first release would serve you better, we will say so.

It depends on scope, so we price after a short discovery call. You get a written proposal with a fixed price for a fixed scope, broken into milestones, before any work starts. If the scope changes, we agree the change in writing first.
