SaaS Development

A SaaS is not just an application: it's an application, an infrastructure, billing, authentication and reliable operations. LaMeDuSe builds your SaaS and can host it on our own European infrastructure.

The problem you're facing

SaaS projects rarely fail on code: they fail on infrastructure. The app holds up in the demo, then collapses at the first traffic peak; billing ships late; nobody planned backups. Between the agency that develops and the generic host, operations fall between two chairs.

Our answer

We build your SaaS with operations in the crosshairs: multi-tenant architecture, scalability, monitoring, backups and billing designed in from the start. And if you wish, we host it on our European cloud : the same team writes the code and runs production.

What LaMeDuSe takes care of

  • Multi-tenant architecture and billing model
  • SaaS application: onboarding, tenant spaces, roles
  • Secure authentication and subscription management
  • Scalable infrastructure (Kubernetes) with monitoring
  • Automated backups and recovery plan
  • Optional hosting on our European cloud
  • Post-launch maintenance and evolution

    Product discovery

    Workshops with your business teams to turn the need into scope, user journeys and measurable success criteria.

  2. 2

    Design & architecture

    Wireframes, technical architecture and documented stack choices: every decision is argued and reversible.

  3. 3

    Iterative development

    Regular releases to staging environments, systematic code reviews and demos at every iteration.

  4. 4

    Production & operations

    Automated deployment, monitoring, bug fixes and continuous improvements with the same team.

Relevant technologies

React & Next.jsNode.js, Go, PythonPostgreSQL, RedisKubernetes & DockerCI/CD GitHub Actions

Security

Systematic code review, secrets management, monitored dependencies and security testing built into the development cycle : security is a starting requirement, not an option.

Hosting & infrastructure

We host your applications on our own European infrastructure (France, Germany, Switzerland): development and operations are carried by the same group, with no dependency on US cloud.

Maintenance

Application maintenance contracts covering bug fixes, upgrades, feature evolution and user support : the team that designed the software is the team that keeps it alive.

Why LaMeDuSe

LaMeDuSe operates its own cloud infrastructure in France, Germany and Switzerland. Your SaaS can be hosted there from day one, with teams that develop AND operate : a model few agencies can offer.

Frequently asked questions

A billable SaaS MVP typically starts between €40,000 and €80,000 depending on scope. We advise launching a reduced scope, validating paid adoption, then extending : rather than building everything before selling.

No. Our European infrastructure offers a sovereign alternative: same capabilities (Kubernetes, scalability), European jurisdiction. For clients sensitive to GDPR compliance or the Cloud Act, it's a sales argument.

Yes: payment integration (Stripe or equivalent), subscription management, free trials, pricing tiers and billing webhooks.

Containerised architecture on Kubernetes, with autoscaling sized to your volumes. Pre-launch load testing validates behaviour under peak, and monitoring alerts before your customers notice.
