What your SaaS product includes

Product scoping & pricing

ICP, pricing model and MVP scope set before the first line of code, so you only fund what actually sells.

Native multi-tenancy

Each client organisation isolated at database level: Row Level Security, or one database per tenant for critical needs.

Stripe subscriptions

Trials, plan changes, proration, invoices and per-country tax: customers manage their own subscription from V1.

Activation-driven onboarding

Welcome flows, useful empty states and clear error messages: your users understand the product within minutes.

RBAC roles & permissions

Fine-grained role-based rights within each client organisation: everyone sees and does exactly what concerns them.

Feature flags & public API

New features rolled out gradually with feature flags, and a documented public API for your integrations.

MRR, churn & analytics

MRR and churn dashboards, product analytics (Mixpanel, PostHog) wired in: you know where revenue is won and lost.

Full product ownership

Git repository, infrastructure as code and hosting accounts in your name: no proprietary lock-in, no agency dependency.

Three moments in the lifeof a SaaS product

A SaaS is not built in one go. The right scope depends on what you need to prove right now: that the market exists, that the product holds up, or that it absorbs growth.

You need to prove the market

Sellable MVP

The goal is not to ship a complete product, it is to ship the smallest product someone agrees to pay for. We cut everything that is not required for that proof, but we keep what makes payment possible: accounts, subscription, billing. An MVP that cannot take money proves nothing.

  • Scope reduced to the core promise
  • Sign-up and user accounts
  • Subscription and online payment
  • Usage metrics from day one
  • Delivery in 10 to 20 weeks

Instead of: six months of development before the first user feedback.

You have paying clients

Multi-tenant product

The product works and the first clients renew. The stake becomes structure: cleanly isolating each account's data, handling teams and invitations, opening different pricing plans, and making onboarding self-service so that every new client does not cost you a day of your time.

  • Data isolation per account
  • Teams, invitations and roles
  • Pricing plans and plan changes
  • Self-service onboarding
  • Stripe billing and failed-payment handling

Instead of: an account created by hand for every client, an invoice issued by hand every month.

You are absorbing growth

Scaling up

Data and user volume start to weigh on response times, and incidents get expensive because clients run their business on it. The work becomes performance and operations: instrument, measure, fix the costly queries, and put in place what lets you see a problem coming before the client does.

  • Performance audit and slow queries
  • Caching and job queues
  • Monitoring, alerting and on-call
  • Tested backups and restore plan
  • Staging environments and zero-downtime deploys

Instead of: finding out about the outage from an angry client's email.

From your vision to first MRR

A method built for a subscription product: we validate the business model, craft the activation journey, then build a technical base that will hold under growth.

We start by framing your SaaS vision: ICP (ideal customer profile), positioning, business model (freemium, trial, usage-based) and pricing. Together we define the MVP scope and north star KPIs (MRR, activation, churn).

The questions we get asked the most.

Between 10 and 18 weeks for a market-ready MVP, depending on complexity (modules, integrations, advanced multi-tenancy). We give you a precise timeline from the brief, with clear milestones and weekly check-ins. The breakdown of SaaS packages is on the dedicated page.

We natively integrate Stripe Billing: monthly or annual subscriptions, automatic prorating, plan changes, pause/resume, PDF invoices, granular tax management by country. Your clients can manage their subscription autonomously from their dashboard.

We use Postgres Row Level Security by default, each organisation is fully isolated at the database level. For critical needs, we can also deploy a database per tenant. Zero leakage possible between clients.

A business application serves your own teams internally; a SaaS is a product sold by subscription to outside customers, so it needs billing, account management and acquisition. If you're still unsure which model fits, we settle it during a strategy and consulting engagement. Many founders also launch a product showcase site alongside to capture demand.

You get 30 days of follow-up included to fine-tune things once the first paying customers arrive. After that, our maintenance & growth offering takes over for new features, activation improvements and technical upkeep. The source code stays 100% yours, on your GitHub.

On our public price list, a SaaS MVP starts at €5,000 to €10K, delivered in 6 to 8 weeks, and a sellable V1, with subscriptions, accounts and teams, sits between €10K and €20K, delivered in 9 to 12 weeks. Beyond that, for a multi-tenant product at scale, cost is driven by performance and operations more than by features, and is quoted on request. The packages and budgets page details the tiers, and the quote comes out of the scoping workshop.

Not necessarily, and the opposite often works better. An MVP collecting its first subscriptions is worth far more in an investment conversation than a prototype with no revenue, because it turns an assumption into proof. Our recommendation is to fund the minimum scope that allows you to invoice, then open the funding conversation with real usage figures in hand.

You own the hosting accounts and the database, opened in your name: nobody can cut you off from your own product. On operations, two options. Either your technical team takes over at delivery, with the procedures and monitoring already in place. Or we keep on-call duty and updates through the Maintenance & Growth offer, with contractual response times.
