Turning an idea or an internal tool into a SaaS product means solving problems a normal website never has: keeping each customer's data separate, charging subscriptions reliably, managing users and roles, and staying up as you grow. We design and build SaaS products for UK founders and businesses, from the first version to a platform that handles paying customers.
Why Choose Us
We've built and run our own platforms, including the Versla marketplace and Cloud Print PRO, so we know what changes once real customers start paying. We use SvelteKit and FeathersJS for fast, real-time apps, Stripe Billing for subscriptions, and Docker with CI/CD for safe releases. We'll also tell you what to leave out of version one.

Frequently Asked Questions
What does multi-tenant mean?
One platform serves many customer organisations, with each one's data kept strictly separate. It's cheaper to run and easier to update than a separate copy per customer. We choose the right separation approach for your security and compliance needs.
How do you handle subscription billing?
We use Stripe Billing for plans, trials, upgrades, downgrades, invoices and failed-payment retries, with webhooks keeping your app in sync. Customers can manage their own subscription through Stripe's customer portal or a custom screen.
Should I build an MVP first?
Almost always. A focused first version gets you real feedback and revenue sooner. We'll help you decide which features matter for launch and which can wait.
Which technology do you use?
Usually SvelteKit for the front end and FeathersJS on Node.js for the API, with MongoDB or PostgreSQL. It's fast, supports real-time features and is straightforward to maintain. If you have an existing stack, we can work with that.
Who owns the code?
You do. The code, the infrastructure accounts and the Stripe account are yours, and everything is documented so you're never locked in to us.
Can you add mobile or desktop apps later?
Yes. Because we build the API first, the same backend can power iOS, Android and desktop apps when you're ready.
