Et si la voiture de fonction avait trouvé son challenger ? Dans cet épisode d’Océan Vert, je reçois Arthur de Jerphanion, cofondateur de Tandem, qui accompagne déjà plus de 180 entreprises et 3 500 salariés dans la mise en place du vélo comme alternative simple, durable et… rentable.

Au programme :

• Pourquoi le vélo d’entreprise n’est pas qu’un gadget “bobo citadin”

• Comment Tandem enlève toute la charge aux entreprises grâce à une solution clé en main

• Les avantages fiscaux et RSE (loi LOM, déductions fiscales, TVA, etc.)

• L’impact carbone mesurable et concret : chaque trajet compte

• La vision d’Arthur pour faire du vélo un réflexe quotidien en France

👉 Spoiler : non, les “bobo cyci” ne sont pas la cible. La vraie révolution est dans les villes moyennes, les zones périurbaines et industrielles.

Meet Alexander Sobolenko, co-founder of Releaf Paper.

The discussion explores his entrepreneurial journey, from a corporate career at Lenovo to building startups in different industries, and ultimately launching Releaf, a company that produces paper from fallen leaves.

Alexander explains how the idea emerged, the technical innovation behind transforming leaves into pulp, and the dual environmental benefits: reducing deforestation and valorizing green waste that would otherwise be incinerated or composted. Releaf’s process achieves significant CO₂ savings compared to both virgin and recycled paper.

The conversation covers the challenges of seasonality, building a supply chain with municipalities, and positioning the product in a market where costs remain higher than conventional paper. Releaf has already worked with major partners such as Uber Eats, BNP Paribas, LVMH, and L’Oréal on pilot projects, proving that large brands are ready to pay a premium for sustainable packaging and communication materials.

Alexander also recounts the relocation of the company from Ukraine to France in 2022, driven by the war and supported by Business France and the local innovation ecosystem. Today, Releaf operates a factory in Île-de-France and continues to refine its technology while scaling its impact.

This episode highlights the story of a startup tackling two global challenges—waste management and deforestation—while navigating the realities of innovation, cost, and customer expectations.

Meet Chloe So, the CEO and Co-Founder of PulpaTronics. Chloe wants to tackle a 45 billion pieces market, by introducing the first Metal-free chipless RFID tags. Her playground: fashion industry, packaging, logistics, healthcare... Though she is at an early stage, Chloe already captures the vision on how to scale the business and stay as close as possible to the customers operation through licensing.

A great conversation on innovation, circular economy, and scaling a deeptech startup.
