Services SaaS Product Development

From concept to scale: four SaaS platforms, each with their own trajectory and impact.

Multi-tenant architecture, subscription billing, user management — we have built SaaS platforms that processed billions in transactions and scaled to thousands of organizations. That experience is now yours.

What we buildWhere are youReal examplesFAQ

Every layer of a SaaS product, covered.

We build SaaS products end to end — from architecture decisions on day one to the features your customers will use on day one.

🏛
Multi-tenant architecture
Proper tenant isolation, shared infrastructure where it saves money, separate where it matters for compliance or performance. Built right from the start.
💳
Subscription & billing
Stripe, Mollie, or custom billing logic — usage-based, seat-based, or flat fee. Trial periods, upgrades, invoicing and dunning handled properly.
👥
User & permission management
Role-based access control, organization hierarchies, SSO and social login. Complex permission models that stay maintainable as you grow.
📊
Analytics & reporting
Embedded dashboards, data exports, and usage analytics — giving your customers visibility into their data and giving you visibility into how they use your product.
🔌
Integrations & API
Public APIs, webhooks, and native integrations with the tools your customers already use. Built to be a platform, not just a product.
🔒
Security & compliance
GDPR-compliant by design. Audit logs, data residency options, penetration testing support, and the documentation your enterprise customers will ask for.

Pre-product
You have an idea, not yet a product
Scope it. Architect it. Ship it.
We help you scope what to build first, design the right architecture for the future you are planning, and ship a working MVP in 6 weeks — without the technical debt that most early-stage products carry.
  • Product scoping & technical architecture
  • MVP in up to 6 weeks
  • Built to scale from day one
Growing
You have paying customers and need to move faster
Embed with the team. Ship more, faster.
We embed into your team or take ownership of specific workstreams. We help you ship features faster, deal with scaling problems before they become crises, and reduce the maintenance burden of moving quickly in the early days.
  • Dedicated development team
  • Performance & scalability work
  • Feature development at pace
Established
You have a mature product that needs modernizing
Modernize without stopping the product.
Legacy codebases slow teams down and make every new feature harder than it should be. We modernize without stopping your product — migrating architecture, improving test coverage, and clearing the technical debt that is holding you back.
  • Legacy modernization
  • Architecture migration
  • Technical debt reduction

Frequently asked questions

The questions we get asked most often when starting a SaaS project.

A focused SaaS MVP with core features — user auth, billing, the main product workflow — typically takes 2-6 weeks. We scope carefully before we start so the estimate is realistic, not optimistic.
Before writing a line of code we work with you on what to build first, how to architect it for the future you are planning, and what to leave out of the MVP. Most SaaS problems start with bad early decisions — we help you avoid the common ones.
Yes. We work with Stripe, Mollie, Hubspot, Exact and custom billing logic. Usage-based, seat-based, flat fee, or hybrid — we have built all of them. Trial periods, upgrade flows, invoicing, dunning and revenue reporting included.
Yes, and this is something we have done for over 16 years with Negometrix. We know the tradeoffs between shared database, schema-per-tenant, and database-per-tenant — and we will help you pick the right model for your use case and budget.
Most of our SaaS clients continue with us on a retainer for ongoing development. We stay involved — shipping new features, monitoring performance, and evolving the architecture as your user base grows. We do not hand over and disappear.
