CEO of Paebbl: Getting the Whole Value Chain to Back Low-Carbon Concrete

Marta Sjögren, Founder and CEO of Paebbl, joins Alex Cameron, Founder of Decarb Connect, to talk about one of the hardest problems in deep tech: getting a whole industry to move together.

Cement and concrete touch nearly every built asset on the planet, yet the value chain is fragmented, margin-sensitive, and deeply risk-averse. Marta breaks down how Paebbl is navigating that from the inside, with investors across the stack and a carbon-neutral bridge in the Netherlands already in the ground.

This conversation goes deep on what "value chain activation" actually looks like in practice, where adoption breaks down, how to map incentives across buyers with completely different risk profiles, and what it takes to get a first-of-a-kind project from interest to commitment. If you are building in hard materials, construction, or industrial decarbonisation, this one is worth your time.

What you will take away from this episode

• Why having investors across the value chain changes deal dynamics, not just your cap table optics
• How to map incentives when your buyers operate on completely different margins and procurement timelines
• Where low-carbon materials most commonly stall, and who in the middle is the real blocker
• What actually moved Paebbl's carbon-neutral bridge project from conversation to construction
• Why value chain activation is market-specific, and which regulatory environments structurally make it easier
• How to keep stakeholders engaged at first-of-a-kind scale when every risk feels novel
• What the EU's reindustrialisation push and low-carbon procurement rules mean for companies building in this space
