Your business deserves more than a shared spreadsheet. Ship your custom SaaS.
We design and build SaaS applications tailored to your business: clean workflows, centralized data, multi-user, accessible anywhere — and that you actually own.
Fits your exact processes
You own the code
First delivery in 6 to 10 weeks
From chaos to clear decisions
When the tool fits you, information stops getting lost between spreadsheets, emails and shared drives.
Shared Excel, duplicates, broken formulas, manual exports, digital sticky notes. Nobody knows which version is the right one.
A single source of truth, screens built around your roles, real-time KPIs, automations that kill double-entry forever.
Why a custom SaaS rather than an off-the-shelf tool?
Vendors sell a grid. Your business doesn't fit in it.
Generic SaaS is rigid
Your processes are your edge. Off-the-shelf SaaS forces you into their model, and you lose what makes you different.
You pay per seat, forever
The more you grow, the more you pay. Past 50 users, vendor SaaS costs often exceed an amortized custom solution.
Your data lives elsewhere
Migration, export, compliance, sovereignty: with vendor SaaS you're dependent. Custom-built, you choose where your data lives.
Integrations are fragile
Every SaaS has its API, its limits, its pricing changes. More tools means more integration debt. A unified custom SaaS simplifies everything.
Evolution depends on the vendor
A feature you need tomorrow might sit in the vendor backlog for 2 years. Custom-built, we add it in the next sprint.
Stacked SaaS hides the real cost
A CRM + a project tool + a billing tool + a reporting tool + Zapier in between: the monthly bill quickly exceeds the cost of one unified SaaS built for you.
What you gain with a custom SaaS
Operational benefits measurable from the first months.
Your processes, automated
Quotes, invoices, follow-ups, accounting exports, alerts: everything that used to take hours by hand becomes automatic and reliable.
A single source of truth
No more diverging Excel files and reminder emails. Everyone sees the same up-to-date data, with permissions matching their role.
Mobile and accessible anywhere
The app runs in any browser, on any device. Your field teams, remote workers and office staff stay in sync.
Data-driven decisions
Dashboards, business KPIs, alerts: you decide on current numbers, not on an Excel export from three weeks ago.
Controlled security and compliance
Hosting in France or Europe, GDPR, encryption, backups, access logging: security is scoped from architecture day one.
You own your tool
The code is yours. You can evolve it with us, with another team, or internalize it. No vendor lock-in.
Our method
Five steps to go from idea to a SaaS running in production.
Business scoping
We start from your real processes, identify what costs time, what gets lost, what slows you down. Outcome: a costed MVP scope and a realistic timeline.
UI/UX design
Wireframes and interactive mockups to validate the experience before any code. We iterate with your field teams — the ones who will actually use it.
Iterative development
Two-week sprints with regular delivery to a staging environment. You see the app grow, you test, you steer.
Production launch
Existing data migration, user training, progressive rollout. We stay alongside during the transition.
Continuous evolution
The application lives with your business. We add modules, optimize, monitor performance and security over time.
Typical example
A representative case from projects we deliver.
40-person B2B services SMB. 12 sales reps, 3 admin staff, a director tracking pipeline. Current tools: a generic SaaS CRM, Excel for reporting, a separate quoting tool, a shared inbox.
Reps re-enter leads three times. Reporting takes 2 days a month. The vendor CRM costs €18k/year without addressing business needs. Excel files diverge.
A single SaaS: lead management, quotes, billing, customer follow-up, real-time reporting and automations. CRM data migration, 2-day training, full rollout in 1 month.
No more double entry, one-click reporting, ~1.5 person-days saved per week. Monthly cost divided by 3 vs the previous SaaS stack, code owned in-house.

Frequently asked questions
Expect 6 to 10 weeks for a working MVP in production on a scoped perimeter, and 4 to 8 months for a more complete SaaS with several business modules. Timing depends on scope and integrations.
A production MVP typically starts between €25k and €80k depending on complexity. A complete business SaaS often lands between €80k and €250k. We provide a costed scope from the first phase.
You do, entirely. The source code is delivered to you, hosted on your Git if you want. You can evolve it with us, with another team, or internalize it.
Hosting in France or Europe (Scaleway, OVH, AWS Paris/Frankfurt) — your choice. GDPR scoped from architecture: data minimization, encryption, logging, user rights. On-premise is possible if needed.
Yes. We start with an audit of sources (CRM, Excel, existing database), build the migration pipeline, run test cutovers, then the real one. No historical data is lost.
We stay alongside you for support and evolution: monitoring, fixes, new modules, performance and security tuning. You can also take it back in-house whenever you want.
