Seven early-stage startup companies have been selected to compete for a top prize of $10,000 at the 14th annual SPIE Startup Challenge at Photonics West on Jan. 30. The SPIE Startup Challenge is a competitive entrepreneurial platform for new businesses that use optics and photonics for innovative products or applications. Participating teams are competing for sponsored prizes, in addition to gaining increased visibility with potential investors. Cash prizes of $10,000, $5000, and $2500, provided by Startup Challenge founding partner Jenoptik, will be awarded to the top three finalists. The SPIE Startup Challenge is also supported by lead sponsors Hamamatsu and Thorlabs and supporting sponsor NextCorps Luminate. Swave Photonics, winner of the 2023 SPIE Startup Challenge.

The industry-judged competition will hear from teams of finalists pitching new products in photonics-enabled health care and deep tech. Competition judges include venture capitalists and business-development experts from the photonics industry, who will vet applicants for their business case, financial case, and competitive advantages. Teams competing in the Startup Challenge will get feedback on their business and pitch from business-development experts and investors. Products this year encompass innovations in medical applications, photovoltaic technology, and manufacturing.
