Autofracture, the TBD company, is in stealth mode with Shannon leading the bootstrapping effort. The estate of Dr. James Kami sponsored the initial lab equipment. It's also a part of the EdmundOptics StartUp program. To date, Autofracture has received no outside funding.
Although Open NanoCarbon has closed, it received minimal funding, in addition to Shannon's self-donations of money and time.
A few years ago, Shannon wrote about why she feels strongly about science, technology, and solid carbons. Read her blog: on Autofracture and science (2017), and Autofracture (2016).
