Autofracture, the TBD company, is in stealth mode with Shannon leading the bootstrapping effort. 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).
