CleanFiber closes a further round of investment

Angel portfolio company CleanFiber has created a novel process to create high-quality cellulose insulation from recycled cardboard boxes. 

We made an angel investment in the seed round of CleanFiber in 2016, and since then they have successfully closed a Series A. This latest round of investment takes them to a total of over $20m raised.  CleanFiber is starting to ramp up production on its pilot line, and has millions of dollars of preorders from customers to keep it busy.
