Twenty years turning health data into product.
From brain signal to digital twins, one throughline: getting hands on medical data and turning it into a product that holds up. Clinical, regulatory, industrial. I'm Montaine Marteau, PhD and biomedical engineer, fractional MedTech CPO / CPTO.
Five kinds of health data.
Few product profiles cover this spectrum. That's the differentiator: medical data, in every form, from the lab to the clinic.
The journey, company by company.
Varian Medical Systems
now Siemens HealthineersQA Engineer, Product Support, PM France then PM EMEIA. Fourteen years at the world leader in cancer treatment: medical device vigilance, CAPA, ANSM / FDA coordination.
Medexprim
First PM, then CPO, then CTPO on the executive committee, in eighteen months. Leading an acquisition (M&A) and handling a headcount crisis (from 20 to 50, then to 35 people).
BC Platforms
Product leadership after an acquisition: merging and managing the product portfolio, combining BC Platforms' genomic data platform with Medexprim's radiomics platform. Solutions deployed across 25 countries, international team (Finland, France, United Kingdom).
Iris Prévention
Product & Tech audit (delivered October 2025): interviews, review of internal tooling, observation of practices. Then support on hiring a CTO, a testing strategy and a 'managing your backlog' training session.
Board4Care
Fractional CPTO of a clinical decision-support software for oncologists. Roadmap steering, automated release traceability (issues → tests → V&V → release notes) towards Medical Device certification. JEI and CII innovation filings, contributions to i-Lab and Horizon Europe applications.
From device vigilance to software certification.
The regulatory framework becomes a working tool rather than a brake. Teams keep their delivery pace.
AI applied to imaging and health data.
ARTEMIS
€9.4MDigital twins of the liver and heart (MASLD and cardiovascular complications). A 'Smart Dashboard' for clinical decision support. BC Platforms as partner.

MedTech talks & podcasts
All my talks →Fractional CPO / CPTO, in practice.
What is a fractional CPO or CPTO?
An experienced product (and tech, for a CPTO) leader who joins your team a few days a week, with the seniority of an executive committee member, without the cost or delay of a full-time hire. They decide, arbitrate and structure from the first weeks.
Why a MedTech-specialised CPO rather than a generalist?
In MedTech, product and regulatory cannot be separated: every roadmap choice affects certification (IEC 62304, MDR, ISO 13485). A profile who has lived device vigilance and ANSM/FDA files avoids bolted-on processes that slow delivery down.
For what kind of company?
Startups, scale-ups and SMEs in health (medical device software, health data, AI in healthcare) that have the vision and the customers, but not yet the product structure: a first PM to coach, a backlog to steer, a certification to prepare, innovation dossiers to secure.
How long, and at what pace?
Engagements of 3 months minimum, 1 to 3 days a week depending on the need. A first 30-minute call to frame things.
Shall we talk about your MedTech product?
A first structured video call. We look at your situation, and whether I'm the right person to help.
