In this episode, Ole Olesen-Bagneux is joined by Gaëlle Seret, product leader, writer, and enabler of data transformations at scale. Known for her clear-eyed writing on Substack, Gaëlle brings a mix of operational pragmatism and strategic depth to the question of what it really takes to build data-driven organizations.

Drawing from hands-on experience across finance, energy, and retail, Gaëlle reflects on the invisible labor behind good data work — and why transformation always starts with the people who love what they do.

Together, they explore:

• Her journey from finance analyst to data product evangelist.

• What makes domain-driven design useful for data teams.

• Why most transformations fail without cross-functional “allies.”

• How to apply product thinking in overlooked domains like IT.

• Writing, community, and the value of making complex ideas accessible.

🎧 Tune in for a conversation about data culture, organizational change, and why understanding the “why” behind your work might be more important than the stack you’re using.
