He is an Operating Partner and investor at C4 Ventures, bringing extensive expertise in CommerceTech, platform strategy, robotics and AI-driven operational transformation.

Throughout his career, he has worked with global retailers and technology companies to anticipate major technology shifts and transform them into scalable growth platforms. As CEO of REWE Digital, he backed commercetools at an early stage, recognising the transition from monolithic architectures to composable commerce well before it became an industry standard. This strategic move contributed to the company’s later development into a unicorn.
He also led the acquisition and scaling of ZooRoyal, successfully integrating a digital-native business into a major retail ecosystem while retaining its entrepreneurial character.

At Kingfisher plc, Jean-Jacques drove the transition towards platform-based commerce, integrating Mirakl and launching marketplaces across retail banners including B&Q and Castorama. He also championed automation and robotics initiatives designed to improve logistics and last-mile efficiency.

His current work extends into Physical AI, automated operations and Agentic Commerce. He advises leading technology companies on the development of AI-native and “agent-ready” infrastructures, while also supporting work in neurosymbolic AI for enterprise decision-making.
