What we build

Five tool families, one logic: automate what slows you down.

We don't do showcase sites or e-commerce shops here. Only internal or business tools, custom end-to-end.

Custom CRM

Sales pipeline, contacts, scoring, email integration. For teams outgrowing standard Hubspot/Pipedrive.

Scraping & data collection

Automatic data collection from external sources (directories, public sites, APIs), enrichment, dashboards. For lead gen and market intel teams.

Automation & workflow

Auto-replies, prospecting sequences, lead scoring, ETL between tools. Anything you do manually that could run on its own.

Internal dashboard / reporting

Unified view of your business data (CRM, Stripe, GA, ERP). Real-time dashboards, exports, configurable alerts.

SaaS MVP for founders

From prototype to v1 in a few months. Modern stack, scalable, built to iterate fast and pivot without rewriting everything.

We don't sell dev. We sell time saved.

A custom business tool that automates your processes, frees your team, and gives you a measurable competitive edge.

The rest is generic tooling that never quite holds up.

How it works

Three phases. Iterative. Validated at every step.

01
Week 1-2

Scoping

Process diagnostic, stack choice, specs, fixed quote for the rest. One call + one written scoping deliverable.

02
Week 3 → delivery

Iterative MVP

First usable deliverable quickly. Short sprints (2 weeks), review at each sprint end, live adjustments.

03
Ongoing

Production & evolutions

Production deploy, training, monitoring. Evolutions based on your feedback and business changes. Optional maintenance.

Our commitments

Six guarantees. No asterisks.

01

Fixed quote after scoping

Once scoping is validated, the MVP price is locked. No mid-project add-ons, no delivery surprises.

02

Code 100% yours

Git repo in your name from day 1. You get the full code, credentials, documentation. No technical lock-in.

03

Modern, tested stack

TypeScript, automated tests, systematic code review. No quick hacks that break at the first evolution.

04

Short iterations

2-week sprints with demo and validation at the end of each. You see the project progress continuously, not after 6 months of silence.

05

Maintenance available (no lock-in)

We can maintain the tool after delivery (optional contract). If you prefer to manage internally or switch partners, the code is ready for it.

06

GDPR + security

Automatic backups, security audits, GDPR compliance. Hosted on our datacenter in France or with you, your choice.

Pricing

On quote. Always.

A custom business tool can't be quoted in 2 minutes. We start with paid scoping — it's our filter, it's your guarantee of seriousness. No off-the-cuff prices, no false promises.

  1. 01

    Paid scoping

    Process diagnostic, stack choice, functional specs. You walk away with a fixed quote for the rest. If you don't continue, the scoping stays yours.

  2. 02

    MVP

    First usable deliverable, in iterative sprints. Review at each sprint end, live adjustments. Quote locked from scoping.

  3. 03

    Production & evolutions

    Production deploy, training, monitoring. Evolutions quoted as needed based on your business. Optional maintenance.

Scoping is the qualification — for both sides. If we're not aligned or the project isn't mature, we'll tell you straight.
