Benny Buller
Founder & CEO of Velo3D
Benny Buller started his career in Israel in the Technology unit of the intelligence forces. While there he learned to appreciate the values of imaginative innovation, precise execution, team work, diversity of opinions and that there is no impossible mission to the ones who dare. For his unique contributions, he was awarded by the president, the prestigious national security award. Benny then joined Applied Materials, where he led the work on semiconductor wafer inspection platform and later on electron beam mask writing system, becoming aware to the new growth opportunities in Solar, he decided to leave Applied Materials and join his first start-up, Solyndra. Joining Solyndra as VP of back end technology and engineering in its earliest stage he defined the company’s product by a series of inventions that became the company’s core IP. He hired an excellent team and led it from early concept through product demonstration, manufacturing process development, equipment design and early scale up. However, as the cost model was firming up, he became convinced, four years before the company’s collapse that the company’s cost structure is fundamentally inferior to First Solar, the cost leader of the industry Impressed by First Solar’s cost advantage and its momentum he joined First Solar as director of device physics and built this team. He pushed it from support of incremental improvements to more radical device research and innovation, resulting in crushing of the CdTe cell and module efficiency world records. . After being promoted to VP Module integration, heading all the technology development for the CdTe PV module, he reorganized the development department and realigned its processes, methods and interactions with the manufacturing organization that resulted in doubling the module efficiency improvement rate. Benny graduated from the Jerusalem University in Physics. He is also an Electrical Engineering (communications) graduate from the Technion in Israel. He has more than 70 published patent applications as well as more than 15 granted patents. Benny is married to his lovely wife Ronit and they have four children. His favorite way of spending his free time is by hiking with his family. He can be reached at [email protected].

Melanie Matheu
CO-Founder & CEO of Prellis Biologics
Matheu co-founded Prellis Biologics in October 2016, with the mission to create fully vascularized human tissues and organs for transplantation. Her realization that the tiny blood vessels necessary for creating human organs could be replicated using the laser technology at the center of her PhD thesis work, led to development of the blended engineering and biology approach Prellis is using to solve the human organ shortage. Dr. Matheu is an expert in laser-based imaging of the immune system and developed Prellis’ platform technology. She brings her multi-disciplinary experience in specialized laser microscopy, cell biology, physiology, and biophysics to address the unsolved biomedical challenge of rapid 3D printing of large, vascularized tissues.
