Gregory Mark

Gregory Mark is a three-time founder and MIT-trained aerospace engineer who is rebuilding how physical things get made. After inventing continuous carbon fiber 3D printing and taking Markforged from a garage idea to a $2.1B public company, he launched Backflip AI in 2024, a generative AI tool that turns text, sketches, and scans into 3D-printable, manufacturable models. Backflip raised a $30M Series A co-led by NEA and Andreessen Horowitz, with angels including Microsoft CTO Kevin Scott and 'Attention Is All You Need' co-author Ashish Vaswani.
