Why Pyonnier Exist
At Pyonnier, we believe that no technological innovation should fail due to a lack of structure or weaknesses in R&D management.
We provide the framework, clarity, and predictability that R&D teams need to work with peace of mind and fully realize the value of every investment.
Stability in service of creation, organization in service of prosperity
At Pyonnier, we believe the future of technology depends on the rigor and measured approach with which R&D is guided.
Innovation is not just about ideas. It is about transforming bold visions into concrete, sustainable capabilities: structured processes, secured patents, high-performing products, and shared progress. Yet, in an inherently complex research environment, R&D too often suffers from a lack of visibility or a fragile organizational framework. When this happens, companies risk losing a vital part of the value they were meant to bring to the world.
We exist to step up to this responsibility and establish sound governance. Because when backed by a clear and orderly direction, R&D drives long-term competitiveness, secures the solutions society needs, and empowers creative teams to fulfill their mission with absolute confidence.

The Path to Performance
Achievements
Played a central role in the creation and initial phases of various start-ups such as McPhy and AREVA H2 Gen. These companies, which have benefited from additional investments totaling hundreds of millions of dollars, are currently advancing and commercializing cutting-edge clean energy technologies.
Complete restructuring of a team's workflows, transition to a collaborative mode, and development of a new strategic direction for Transvalor Americas, the US subsidiary of a simulation software company. This initiative increased sales by 40 % in 15 months, and facilitated the transfer of the role to an internally-trained CEO, six months ahead of schedule.

Testimonials
Working with Jérôme was a revelation in terms of quality and responsiveness. From the outset, he exceeded our expectations—not only by facilitating the essential contacts for our market surveys but also by providing expert analysis that greatly enriched our project. His strategic insights on commercialization factors demonstrated a profound understanding of the hydrogen sector and offered vital direction for bringing our client's innovations to market. His industry experience and knowledge of sector needs and emerging trends also made him a valuable asset during client meetings at the outset and conclusion of the study. Jérôme’s commitment to delivering more than was expected, combined with his support in meeting tight deadlines, truly set him apart. I highly recommend him to any organization seeking an industry expert who combines analytical excellence with operational pragmatism.
Although new to the field of standardization and to this vital position of committee chairman, Jérôme immediately took an active part in the standardization work, guiding the group and the discussions to a successful conclusion of the draft standard he was working on. He ensured that deadlines were met and, with the participation of the committee, that the content reflected the different points of view around the table. Working with Jérôme was a pleasure!
