Krystal Biotech, Inc.
One of the first gene-therapy companies to reach patients, it makes VYJUVEK, a gel applied to open wounds that treats dystrophic epidermolysis bullosa (DEB), a rare disease where skin blisters like butterfly wings. Founded in 2016 by husband-and-wife team Krish and Suma Krishnan, who self-funded its start, the company named itself "Krystal" for the clarity and precision it wanted in gene therapy.
