“Greenfield Partners is excited to continue to support DustPhotonics in this upcoming phase of growth, on the back of strong execution by the DustPhotonics team across both product innovation and commercial wins,” said Yuda Doron, Managing Partner at Greenfield Partners. “We continue to be firm believers in the prospect of silicon photonics becoming a key enabler for data centers to meet the increasingly demanding requirements brought upon by AI, as demonstrated by the company’s recent momentum.”

“We are seeing a lot of design-win momentum with our products, and are excited by the new opportunities ahead in both AI and cloud service data centers,” said Ronnen Lovinger, CEO of DustPhotonics. “We are grateful to have a strong group of investors who have been supporting us from the early days, and are delighted to have new partners join our journey ahead.”

“Since undergoing the transition to a silicon photonics chip company from a transceiver company, I have seen the team at DustPhotonics do a tremendous job achieving their milestones on technology, products and business”, said Avigdor Willenz, Chairman of DustPhotonics. “I believe their upcoming innovations will allow them to further grow their position as a leader for next generation merchant silicon photonics products.”
