Heirloom Closes $150 Million Series B

I am excited to share that we’ve closed our $150 million Series B financing round, co-led by Future Positive and Lowercarbon Capital. Japan Airlines, Mitsubishi Corporation, Mitsui & Co., MOL Switch LLC, Quantum Innovation Fund and Siemens Financial Services also joined the round. Repeat investors include leading climate and carbon removal investors like Ahren Innovation Capital, Breakthrough Energy Ventures, Carbon Direct Capital, Lowercarbon Capital, and MCJ Collective.

It's incredibly encouraging to have major players in aviation, shipping, and manufacturing join our round. These partnerships, especially in regions like Japan and Europe where compliance markets are taking shape, highlight the increasing acknowledgment that high-quality carbon removal is crucial for hard-to-abate sectors. They also affirm that we offer one of the most promising solutions for achieving high quality, scalable, and cost-effective removals.

This funding reinforces our core belief: that DAC can only scale effectively to combat climate change if it is affordable. Heirloom’s technology has several unique features that enable our low cost-floor, and I look forward to sharing more details on these in coming months.

But for now, I want to take a moment to thank you all for being part of our journey. We have a clear path to becoming the most cost-effective DAC solution, and we’re thrilled to scale up and make a significant impact in the fight against climate change.
