Call for speakers
Take the stage at Build It Summit
Build It Summit is a stage for people who build, and for people whose ideas move building forward. Come with a hands-on method, a hard-won lesson, or a wider perspective that shifts how the room thinks. A first-time voice with something real to say is as welcome as a returning name. Applications are open.

Builders REX Awards
A concrete deployment with the numbers behind it? Submit it as a REX, shared on a panel.
Submit your REXWhat earns a slot
One thing carries every accepted session: the room leaves with something it did not have before. A method someone can copy. A REX with the numbers behind it. A perspective that reframes the problem. Hands-on or big-picture, what matters is that it is real and yours.
No product pitches. Sessions are editorial: the committee fills every slot on merit, kept separate from sponsorship.
The room you speak to
Build It Summit, BIS × FOST, shares the floor with FOST Paris on 1 to 3 December 2026 at the CNIT, Paris La Défense. Your session sits in front of that combined audience of Builders, teams and the organizations they build for.
