Carbon Biosciences
Carbon Biosciences is a Waltham, Massachusetts preclinical genetic-medicine company building gene therapies on non-AAV parvovirus vectors. Founded by Longwood Fund with gene-therapy pioneers John Engelhardt and Robert Kotin, it uses a proprietary vector engine (PAVE) to design capsids from the broad parvovirus family - including human bocavirus - that carry larger genetic payloads, target specific tissues, and provoke little pre-existing immunity, opening the door to re-dosing. Its lead program targets cystic fibrosis by delivering the full-length CFTR gene to the lung, with a second vector aimed at cardiac disease.
Joel Schneider
Joel Schneider is the founder, president and CEO of Carbon Biosciences, a Waltham, Massachusetts biotech building gene therapies from parvovirus-derived vectors rather than the more common adeno-associated viruses. He launched the company out of stealth in 2022 with a $38 million Series A led by Agent Capital, pairing his operating background with the science of gene therapy pioneer Robert Kotin. Trained as a stem cell biologist with a Rutgers Ph.D. and a Harvard postdoc, Schneider was the first employee at Solid Biosciences before founding Carbon to push vectors that carry larger genetic payloads, target specific tissues such as the lung, and sidestep the pre-existing immunity that limits current gene therapies. Carbon's lead program targets cystic fibrosis.
