Rubi Raises $7.5M to Scale Carbon-to-Textile Materials Platform
CO2 has always been cast as the bad guy. Silent, everywhere, catching blame like a rookie corner getting picked on. Rubi looked at that same molecule and saw something else entirely. Not a liability. Inventory. The kind you cannot see but can absolutely monetize if you know what you are doing.
That shift in thinking just pulled in $7.5M in fresh capital. Applause for Neeka Mashouf, CEO & Co-Founder, and Leila Mashouf, CTO & Co-Founder, who are not pitching sustainability as a slogan but building it into the molecular fabric of how things get made. This round, led by AP Ventures and FH One Investments, with CMPC Ventures, H&M Group, and Talis Capital stepping in, reads less like a financing event and more like a coordinated bet on where materials science is heading.
Rubi’s approach is deceptively simple when you say it fast. Use enzymes to capture CO2 and convert it into cellulose. Slow it down and it starts to hit different. Cellulose becomes textile. Textile becomes product. And suddenly the most resource-intensive parts of apparel production get replaced by something carbon negative with virtually zero water and land use. That is not optimization. That is a quiet takeover of how supply chains think.
And this is not a two-person science project. Arturo Miramontes, Edwin Monroy Delgado, Haley Inselberg, Jenny Knipe, Mario Perez Venegas, Mehran Soltani, Natalie Boulos, Olivia Bewsey, Patrick Gerlinger, Rebekah Holtsclaw, Rosa Hur, Sushant Sinha, Trevor Boram. Titles matter, but what matters more is the collective output. Lab, engineering, research, operations. This is a system, not a moment.
Then the market leans in. Over $60M in multi-year offtake term sheets and agreements. Nobody signs that kind of paper because something sounds clever. They sign because it solves a problem that has been sitting on their balance sheet and their conscience for a long time. Less resource dependency, tighter narratives, and margins that do not get squeezed by volatility upstream.
The takeaway is not complicated, but it is rare. When you turn waste into a feedstock, you change the economics and the conversation at the same time. Rubi is not chasing trends. They are threading carbon into commerce, stitching atmosphere into asset, and leaving a question hanging in the air that most industries are not ready to answer yet… what else are we still calling waste that should already be revenue?
