Web App Development
We build web apps end to end — SaaS products, AI automation, internal tools — from architecture and APIs to the billing, dashboards and integrations that make any of it useful. Then we keep them running. One platform we started in 2016 is still ours to operate.
Globogate went live in 2016 and we still operate it: seven integrated apps, 200+ employer organisations, 5,000+ people through the pipeline. Most of a web app's life isn't the launch — it's the decade after it.

Founders and product teams with a product to build, or one that has outgrown how it was built.
What we're usually fixing
The expensive problems in a web app are decided in the first three weeks and paid for in year two.

Nothing gets built before it's written down, and nothing is written down without the engineers who'd build it.

We take on anything from $5,000, including sites, small custom features, and other work too small to be a service line. The figures on this page are averages from projects we've already delivered, not quotes. Yours gets its own number once we've seen it.

Web app development, answered
Building a software product from the architecture up rather than assembling one from off-the-shelf tools — the data model, the API, authentication, billing, the dashboards and the integrations, plus the infrastructure it runs on. That covers SaaS products, internal tools and AI automation alike. You own the code and the IP.
6–18 weeks to an MVP, depending on scope. Our standard 12-week shape is two weeks of discovery, two of architecture, six of build, one to harden and one to launch. The Architecture Sprint gives you that number in writing before you commit to the build.
Product engineering runs $25K–$100K for a build, fixed-fee once the spec is clear. If you want to lower the number, the fastest lever is scope, and the sprint is where we find out which half of the roadmap matters.
Both, and the MVP is rarely where it ends. Several platforms in our portfolio started as a spec and are still in active development years later — one since 2016, running seven integrated apps for 200+ employer organisations.
Yes. If the product is live and struggling, that's a rescue rather than a build — start with our software project rescue service, which begins with a two-day audit of the code you already have.
Yes. To us it's a web app with a model in it — same team, same price band. The difference is the first step: instead of the Architecture Sprint we start with an AI Opportunity Assessment — one workflow, checked against your actual data, with a go / no-go before anything is built.
Yes — pricing tiers, orders, reconciliation and payouts. We built the supply, checkout and settlement layers of a digital distribution platform, and a commission-tracking system that pays out across web, mobile and social channels.
You do. Full source, repository access, and IP assignment in the contract. No escrow, no lock-in — and the sprint documents are yours whether or not you build with us.
If you want us to. Three options: a monthly retainer covering ops, bugs and small features; a documented handover to your team; or a handover after a defined operate period. Plenty of clients pick the first and stay for years.

One week, four documents: a written specification, an architecture, a fixed-price estimate and an honest recommendation. The fee comes off the build.
