Words from our leadership team

Adtech has become increasingly complex—and that complexity has come at a cost. Publishers have lost control, trapped in systems built to serve industry giants.

At Pubstack, we’re here to change that. Our mission is clear: empower publishers, simplify adtech, and help them reclaim ownership of their revenue.

This is more than a product. It’s a movement. And we’re just getting started.

Loïc Sfiligoï, Hervé Brunet and Guillaume Polaert

Our VCs

What we're building

Pubstack is building a supply intelligence platform that helps publishers maximise the value of their inventory in programmatic advertising.

As buying has shifted towards outcomes, decisioning has moved to the buy side, leaving publishers with limited control over how their inventory is evaluated and priced.

We're building the layer that brings decisioning and real-time signals back to the sell side, enabling publishers to shape how their inventory is bought and valued.
