Weeks, not quarters
Most builds go from kickoff to working app in 2–4 weeks. AI-assisted development takes the slog out of the wiring so we spend our time on the bits that matter — your workflow, your data, your team.
NewAI-assisted builds · 2× faster, same craft
The business apps you've been promising yourself, finally built.
Fuselab is a small UK studio building the custom software growing companies keep meaning to commission. Modern AI development means we can move fast and keep prices fair — without compromising on craft.

Why Fuselab
Software the size of your business, not someone else's.
We're a small studio that does one thing well: build internal tools for SMEs that have outgrown spreadsheets but shouldn't be writing enterprise cheques. No sales engineers, no six-month roadmaps.
Priced like an SME
Fixed scopes, transparent rates, no enterprise minimums. Start with the workflow that hurts most — expand once it's earning its keep.
Yours to keep
You own the code and all the accounts — hosting, database, auth, everything. We document it all. If you change partners or bring it in-house, you don't start over.
Connects to what you already use
Sheets, Xero, Stripe, HubSpot, Shopify, Postgres — anything with an API. One place to see what's happening, one place to act on it.
Tailored, not templated
Built around how your team actually works on a Wednesday afternoon, not how the textbook says it should. The interface follows the process.
Grown-up security
SSO, role-based permissions, audit logs, encrypted at rest and in transit. Enterprise plumbing on an SME budget.
Where we fit
The gap between “this spreadsheet” and enterprise software.
Most of our work lives in that gap. A few patterns we see repeatedly — yours probably looks very different, and that's exactly the point.
Operations dashboards
One screen for the numbers the team actually checks every morning. Live data, sensible alerts, no copy-pasting between tabs.
Customer & pipeline tools
A CRM shaped like your sales process — not Salesforce's. Track leads, automate follow-up, log the calls. Nothing you don't need.
Stock & order management
Stop reconciling stock levels across four tabs and a WhatsApp group. Real-time levels, reorder points, fulfilment status — one app.
Approvals & internal workflow
Expenses, leave, change requests, onboarding. Out of email threads and into one queue with a clear owner and an audit trail.
If you've got a process held together by a shared sheet and a prayer, that's our territory. Tell us about it →
How we build
Four steps. No surprises.
A short, predictable engagement. You typically see something working in the first week. You decide whether to keep going.
01typically half a day
Discover
A workshop with the people who actually do the work. We map the process, scope the build, agree the cost. Fully refundable if you proceed.
02typically week 1
Prototype
A clickable prototype in your hands early — AI-assisted means we sketch the working software, not just wireframes. Cheap to change now.
03typically weeks 2–4
Build & iterate
Short sprints with live demos. You see the app grow, test it against real work, and steer the build as you go.
04launch + ongoing
Ship & support
We train your team, hand over the keys, and stay on call. Bug fixes, small features, a monthly check-in — nothing dramatic.
Stack & integrations
Plays nicely with the rest of your stack.
We're stack-agnostic. We pick the right tool for the job — and connect to whatever you already use. If it has an API, it's fair game.
