Marta Sjögren spent over a decade as a venture capitalist, but a desire to make a meaningful impact drove her to co-found Paebbl. “I wanted to look my kids in the eyes and say, ‘I did my part,’” she shares. Marta’s transition into climate tech was fueled by her desire to use her expertise to scale transformative solutions, ultimately creating a company focused on turning CO2 into sustainable building materials.

Paebbl's groundbreaking technology chemically accelerates a natural process, turning CO2 gas into carbonate rock. As Marta explains, “We just chemically accelerate a process that has existed since the beginning of time.” By using biogenic sources of CO2 and combining them with crushed minerals, water, and non-toxic chemical accelerants, Paebbl is creating sustainable materials for the construction industry. This innovative process is a game-changer for reducing emissions in hard-to-abate sectors like concrete production.

With a team of 45 people spanning 22 nationalities, Paebbl prioritizes diversity in skills and backgrounds. Marta notes that many employees come from industries like oil and gas, mining, and advanced materials, making the company a leader in green job transitions. “We’re hiring for the future,” she says, highlighting the role of generative AI in streamlining operations and reducing costs. This approach enables Paebbl to stay competitive while scaling its impact.

Marta emphasizes the importance of partnerships to decarbonize the built environment, stating, “It’s going to take a movement.” Through strategic collaborations with industry leaders like Holcim and Amazon’s Climate Pledge Fund, Paebbl is driving adoption of sustainable building materials. The company’s mission is clear: to make flagship construction projects, such as Saudi Arabia’s Neom city, massive carbon sinks rather than emitters.

Paebbl exemplifies how innovation and collaboration can tackle one of the world's most pressing challenges: climate change. By turning CO2 into sustainable materials, the company is not only reducing emissions but also paving the way for a greener future. As Marta puts it, “What if the most ambitious construction projects could be the world’s largest carbon stores?”
