SaaS Development
in London
Multi-tenant, billed, deployable. Not a prototype.
We build production SaaS products for founders in London — multi-tenant from day one, Stripe-ready, with the admin tooling you'll actually need at 100 customers. One senior engineer owns the architecture; you don't pay for a three-person team to argue about microservices.
What you get
Concretely, by the time we hand over
- Multi-tenant data model with row-level isolation from commit one
- Stripe subscription billing with usage-metered or seat-based pricing
- Customer admin (workspace settings, members, billing) and internal admin
- Onboarding flow with email verification, password reset, SSO-ready
- Source + infrastructure handed to your accounts
Why this works for London
The local math
London is the #3 startup ecosystem globally and the gateway to European pre-seed. Hiring senior engineers means £100K+ packages and 90-day cycles in a market still recovering from the post-Brexit shuffle. We work async with London founders, bill in USD, ship in two weeks.
Year-one outlay for a single senior hire in London: ~$200K. Our saas development engagement starts at $12,000.
