The CEO driving bold change at PathoQuest
Jean-François Brepson spent 20 years climbing the ladder at Ipsen before making the leap from the security of corporate pharma into the messy, uncertain world of entrepreneurship. Since 2015, he has led PathoQuest and transformed it into a global CRO specialising in quality control of biologics using Next Generation Sequencing. His journey is about resilience, bold choices, and never giving up when the odds are stacked against you.
When I sat down with Jean-François, I walked away with three big lessons:
What I Learnt
- Refocus can save a business. Pivoting PathoQuest from diagnostics into a pure CRO model was a tough call, but it unlocked survival and growth.
- Partnerships are power. A strategic collaboration with Charles River changed the fortunes of the business and showed how the right allies can be a competitive weapon.
- Regulators set the pace. The FDA’s move away from animal testing created tailwinds for PathoQuest’s sequencing approach, opening up a huge opportunity.
What I Liked
Jean-François has an infectious enthusiasm and passion for what he does, delivered with that Parisian flair and an accent you cannot help but enjoy. I loved his determination to lead and his resilience in keeping the company alive through tough times. What really struck me was his attitude toward being bold and choosing the difficult path. That way of thinking really resonates with me and with so many of the other successful leaders I have had on the podcast.
Reflections
What stood out most for me was his honesty about how hard the journey has been. Fundraising struggles, strategic pivots, and the relentless pressure of innovation could have broken a lesser leader. But Jean-François kept going. His conviction and perseverance pulled PathoQuest through and built something meaningful.
Personally, I admired his courage in leaving a 20 year corporate career to take the entrepreneurial road. That choice reminded me that the difficult path is often the one that leads to the most impact.
