On 18 September in Belgium, we are welcoming the most innovative built world event ever held in Belgium — and you’ll want to be in the room.

We’re bringing together 800+ leaders across construction, real estate, tech, and capital for a full day of bold thinking, real-world collaboration, and no-fluff impact.

Why This Matters:

This isn’t just another conference.

The 87 Day is built to shake things up — to challenge old ways of working and push for real progress where it’s most needed: housing, permitting, innovation, investment, and leadership.

If you’re serious about shaping the future of the built world, this is your summit.

What to Expect:

We’ve created three unique experiences — built for impact, connection, and fresh thinking:

🔹 Task Forces

Max 10 people. Real problems. Real solutions.

Work hands-on with peers to shape a roadmap on issues like housing, renovation, PPP, permitting, and more.

🔹 Reverse Pitches

Corporates pitch their problems. Startups can apply to solve them.

It’s matchmaking for innovation — and the results are real.

🔹 Asset Class Roundtables

What’s changed in resi, logistics, healthcare, data centers, and more?

10-minute keynotes + 10-minute “Ask Me Anything” with industry leaders.
