SYS/METHOD
One loop. Two areas. Agents in the circuit since 2024.
Our method: measure, instrument, agents, ship, review
One system, two areas of focus — growth and digital products. We don't sell a catalog of offers: we run a measurable loop, with agents at every step.
SYS/LOOP
The loop, step by step
Measure → instrument → agents → ship → review. Then we start again. Click a step to expand it.
01 — Measure
We start with the data, never with the design: data export, funnel, primary KPI set before anything else.
On an A/B test for an airline funnel, reading the data export showed a drop on the summary page — recommendation: do not ship.
Tools: GA4, SQL exports, Python.
02 — Instrument
We make the result readable: tracking plan, events, dashboards. Without instrumentation, no optimization is attributable.
For Cassiopée, this foundation made it possible to track every hypothesis and cleanly attribute the rise in conversion.
Tools: GTM, tracking plan, Looker Studio.
Case: Institut Cassiopée →
03 — Agents
We put agents in the loop, governed by a protocol: they execute phases, they don't improvise.
For Workfluence, agents produced and reviewed 500 job-profile pages under protocol, at consistent quality and marginal tooling cost.
Tools: Cursor, Claude Code, Copilot, GSD, skills.
Case: Workfluence →
04 — Ship
We ship for real: the result goes into production, not into a slide deck.
That's how BAO went from a practice's need to a 34-screen, 10-PRD prototype, exportable as a bank loan file.
Tools: Webflow, Next.js, Django, A/B tests.
Case: BAO (docAgency) →
05 — Review
We verify, then start again: statistical analysis, post-mortem, next hypothesis. The loop never closes.
For SITL, this review took form completion from 27% to 45%.
Tools: SRM, z-test, segments, post-mortem.
Case: SITL →
| Project | Before | After |
|---|---|---|
| SITL | 100 | 166 |
| Institut Cassiopée | 100 | 220 |
| Infirmière Reconversion | 100 | 250 |
Base 100 = measurement before the engagement. SITL: completion 27% → 45% (+66%). Institut Cassiopée: +120% conversion. Infirmière Reconversion: +150% conversion.
SYS/DÉPART
Based on your starting point
The same loop, four entry points. Each path links to the lever and a case study.
More conversions
We start from the funnel: prioritized hypotheses, A/B tests analyzed on data exports, dedicated landing pages. We only ship what the data validates.
That's the approach that took Cassiopée's conversion to +120% over eight months of testing.
More traffic
Semantic content clusters, technical SEO and agent-produced content for organic; conversion-driven campaigns for paid. The two funnels aren't handled the same way.
For Workfluence, this approach generated 4,000 visits per month from 500 job-profile pages.
Measure first
GA4 tracking plan, GTM tracking, Looker Studio dashboards and journey mapping. We make KPIs readable before any optimization.
On an airline booking funnel, 214,473 rows of data narrowed down to 135,298 visitors and 29 segments led to a decision not to ship.
A product
From PRD to clickable prototype, then from prototype to SaaS. Agents shorten every step without skipping the documentation of decisions.
BAO is the proof: 13 steps, 34 screens and 10 PRDs delivered with agents in the loop.
SYS/FORMATS
Engagement formats
Four ways to work together, from a short diagnostic to a complete product. We pick the right format based on the stakes, not the other way around.
F-01
Audit
5 to 10 days: diagnostic, data export, prioritization.
What we deliver
A ranked list of hypotheses and a roadmap.
F-02
Sprint
3 to 6 weeks: one lever, one KPI.
What we deliver
One change, instrumented, tested and shipped against a single objective.
F-03
Monthly retainer
A continuous loop: measurement, hypotheses, tests, review.
What we deliver
Ongoing growth management, month after month.
F-04
Fixed-scope product
From prototype to SaaS: scoped perimeter, PRDs, screens.
What we deliver
A delivered product, not billed hours.
The format gets defined during the call.
SYS/CALL-FLOW
How a call works
- 01
30 minutes of conversation
Your starting point: a funnel, a product, a data export. No sales pitch, just an on-the-spot diagnostic.
- 02
Written scope within 48h
A scope, a KPI and a format, proposed in writing. Enough to decide on clear grounds.
- 03
Start or not
We start if the scope works for you — no commitment if the timing isn't right.
SYS/NOPE
What we don't do
-
No agency dressing things up: one point of contact, Mathieu Milon.
-
No "we do AI": AI is the tool, never the pitch.
-
No mass scraping: data stays scoped.
-
No decorative dashboards: tracking exists to drive decisions.
