Paebbl Gathers $25M to Boost Carbon Storage Innovations for Buildings

Paebbl, a pioneering company focused on converting captured CO2 into permanent carbon-storing materials, has successfully raised $25 million in a Series A funding round. This new capital will significantly accelerate Paebbl's efforts to scale its innovative technology and establish a sustainable value chain for CO2 storage in building materials, effectively positioning the built environment as a vital player in the fight against climate change.

The funding round attracted a consortium of tier-one financial and strategic investors, including DACH-focused VC Capnamic, Amazon’s Climate Pledge Fund, global construction leader Holcim, and several European industrial family offices such as Aurum Impact, linked to the German concrete and construction company Goldbeck. Existing investors like 2050, Pale Blue Dot, and the Grantham Foundation also participated in this significant funding round.

Founded in 2021, Paebbl has demonstrated impressive growth within its first 18 months. The company has advanced from gram-scale laboratory tests to bench-scale experiments and now operates a fully functioning pilot unit capable of producing 250 kilograms of CO2-storing product daily. In May 2024, Paebbl reached a significant milestone by sequestering its first ton of CO2 in its mineral product and successfully casting its first concrete structures using captured carbon, underscoring the real-world impact of its proprietary technology.

Fueled by the recent funding, Paebbl plans to commission its demonstration plant in the first half of 2025, which will dramatically increase its production capacity to three tons of product per day, effectively sequestering one ton of CO2 daily. This facility will serve as a foundation for the commercial deployment of Paebbl's technology, paving the way for future expansion into a commercial-scale plant.

Paebbl is committed to expanding its existing hubs in Helsinki, Rotterdam, and Stockholm—where most of its 40 employees are based—and plans to open a new hub in the UK. This expansion will enhance the company's operational capabilities and strengthen its position within the industry.

Marta Sjögren, co-founder and co-CEO of Paebbl, expressed pride in the company's rapid progress, stating, “We're incredibly proud of the progress we've made in such a short time, but there's so much more to come. This funding enables us to take even bolder steps in our mission to make the built environment a cornerstone of the decarbonised economy. The challenge ahead is significant, but so is the upside and opportunity.”

Andreas Saari, co-founder and co-CEO, emphasized the importance of strategic partnerships, stating, “We are thrilled to welcome first movers in their respective fields, Amazon and Holcim, as commercial partners that will help bring our vision to the market rapidly. We have the chance to turn the built environment into the world’s greatest carbon sink, having taken a natural process, innovated upon it, and turned it into a commercially viable, scalable service.”

Capnamic managing partner Christian Knott noted what differentiates Paebbl in the market: “What sets Paebbl apart from other companies in the space is their demonstrable ability, across the senior team, to build and scale companies, and execute where it matters. For a young deep tech company, they already have rapidly won multiple customers and key partners, with a continual stream of exceptional talent joining the company.”

Paebbl employs a nature-inspired, technology-enabled mineralization process to convert CO2 into a sustainable industrial raw material, effectively turning buildings into permanent carbon stores. Founded by a team of experienced entrepreneurs—Andreas Saari, Jane Walerud, and Pol Knops—alongside former venture capitalist Marta Sjögren, Paebbl aims to bring scalable carbon removal technology to market within the next decade.

Paebbl represents a collaborative Nordic-Dutch effort, privately financed by planet-aligned investors committed to combating climate change. The company’s innovative approach and strong foundation position it as a leader in the rapidly evolving field of carbon management, showcasing the potential for the construction industry to significantly reduce its carbon footprint and contribute to global sustainability efforts.

As Paebbl continues to advance its technology and expand its operations, it is well-positioned to play a crucial role in transforming the built environment into a key asset in the fight against climate change, fostering a more sustainable future for generations to come.
