As a UK SaaS development agency we build the parts subscription businesses live or die on — multi-tenancy, billing, onboarding and security. First sellable version from £15,000.
Solutions we've built power teams at:
A SaaS lives or dies on the parts customers never see — tenancy, billing, onboarding and security. Get them wrong and every new customer is a fire to put out. We build them in from day one, so version one is something you can actually sell, not a demo.
We start with the model most SaaS builds get wrong late — how tenants are isolated and how billing works — because retrofitting either is misery. A first conversation to map that costs nothing.
A SaaS blueprint from £4,000 designs the multi-tenant architecture, maps the pricing model and gives you a costed, staged build plan — plus an honest call on what version one actually needs. The first sellable build starts from £15,000.
We build multi-tenant and secure by design, with auth, onboarding and Stripe subscriptions live from day one — sellable, not a demo. Milestone-paid, in short stages you can see.
Once you're charging customers, we extend the platform as it grows — or take over an existing SaaS, keep what's worth keeping, and quote the scale-up at a fixed price. The code and the platform are yours on payment.
A white-label workforce platform built to carry any employer's brand, a case-handling platform running a client's whole operation end to end, and a creator platform taking subscriptions through Stripe. Multi-tenancy and billing are dull until they're missing — so we build them in from day one.
Company communication tools assume everyone has a corporate email address, which leaves frontline and deskless workers out of them entirely. CodeLeap designed and built Connect by CoCentric, a messaging and calling platform that onboards workers without one.
Read moreAn established insurer ran claims across a patchwork of legacy case management, shared inboxes, spreadsheets and supplier portals, and wanted one platform in place of all of it. CodeLeap built that platform from the ground up, covering notification, assessment, decision, settlement and repair for policyholders, brokers, handlers, loss adjusters and suppliers.
Read moreUdokk saw growing demand for trustworthy digital health content and had an extensive professional network ready to create it. CodeLeap built the platform where healthcare professionals publish scientific and educational video for practitioners, students and the public, and earn from it.
Read moreThe platform stack under our SaaS builds — billing, tenancy and infrastructure named plainly, shipped-with kept distinct from works-with.
Udokk's creator subscriptions run on Stripe Connect, multi-party payouts included — billing here is proven ground, not a first attempt.
Our SaaS backends are typically Django — the stack behind several platforms we've shipped and still run, chosen for how well it wears.
We've built production web software with React — the fit for the dashboards and consoles SaaS lives in.
One codebase serving every customer with hard walls between their data — we design tenancy first because retrofitting it is misery.
Our shipped platforms run on AWS and Google Cloud, Udokk's on Google Cloud and Firebase — and we plan for the bill as well as the uptime.
Where a SaaS sells through the app stores we've shipped RevenueCat alongside Stripe — one subscription state, however the customer pays.
We work with Next.js for SaaS marketing sites and app shells where it fits — and will say so when something simpler does the job.
This is what comes up most often, not a limit. Bring us something that isn't on this list and we'll get up to speed on it — working with something new is the job, not an obstacle.
Real reviews from clients we have delivered for, on Clutch and elsewhere.
The enthusiasm, understanding of our mission, and passion from the first few minutes of the call were the deciding factors in choosing CodeLeap. Within 3 months of our app launching, we had over 1,500 downloads, appeared in leading publications from Forbes, The Metro, Marie Claire, Women's Fitness and many more, and started raising further investment.
They are incredibly diligent in the quality of work they produce, and go above and beyond when it comes to solving issues faced within the project, and to ensure we meet strict project deadlines. You never feel like you are one of many clients, and they ensure they are always there to help with any need you have, no matter how big or small.
CodeLeap made me feel like my options were limitless in terms of what could be achieved, which was critical to me as we were creating something very unique. I'm glad I chose Codeleap over a large corporation as the personable approach resulted in a smooth and pleasant experience.
Working with CodeLeap was a very good experience from both a professional and personal point of view. These people know what they are doing and are both efficient and clever and made a good partner. I wouldn't hesitate to recommend CodeLeap.
CodeLeap adds so much value and goes above and beyond what I expected. CodeLeap's team is very flexible with all the different requests we've put in front of them. They've also been great with the whole business side of things, and being able to forecast for this industry is really helpful. Overall, I'm completely satisfied with their work — they've been incredibly helpful.
Their flexibility and focus on quality were outstanding.
Marcelo has been wonderful throughout the process and we are very happy.
Absolutely FANTASTIC. This is very much what I had in mind. We're very pleased with your team, thank you all very much.

A first sellable version — multi-tenant, secure by design, with auth, billing and onboarding included — starts from £15,000. A SaaS blueprint, which scopes and de-risks the build first, starts from £4,000. Both are fixed-price, agreed before work starts.
Around three months is our typical project shape from design through launch — and “sellable” is the bar for the first version, not a demo. Bigger platforms take longer; you'll get an honest timeline upfront.
Yes — billing is part of the first version, not an afterthought. We've shipped subscription systems on Stripe, in-app purchases and freemium tiers, so revenue can flow from the day you launch.
You do. Once the work is delivered and paid for, the platform is yours — the code, the system, all of it. You're not renting it from us or tied to us to keep running it.
Yes. We review what's there honestly, tell you what's worth keeping, and extend rather than rewrite wherever the economics support it — then quote the scale-up work at a fixed price, agreed before we start.
A small, experienced team of designers, engineers and problem-solvers working closely with you from first idea to final delivery.
