Lightmatter Secures $155M Series C, Leading Photonics in HPC

Boston-based Lightmatter, a pioneer in photonics, has secured $155M in Series C-2 funding, propelling its innovative technologies to the forefront of high-performance computing (HPC), where AI innovators harness the power of Lightmatter’s advancements to redefine the landscape.

The Series C-2 round led by Google Ventures (GV) and Viking Global Investors brings Lightmatter’s total investment to a remarkable $420 million, catapulting its valuation to an impressive $1.2 billion.

Lightmatter, under the leadership of CEO Nick Harris, is at the forefront of developing cutting-edge photonic technologies, reshaping the landscape of chip computation and communication. This breakthrough innovation is poised to benefit major cloud providers, semiconductor companies, and enterprises grappling with AI innovators’ demands for high-performance computing.

“Lightmatter is positioned to be a key driver in powering the next generation of computing systems to enable AI innovation further. Through photonic technologies, Lightmatter is ensuring steady progress in computing performance despite growing power consumption challenges and slow progress with transistor scaling,” said Lightmatter co-founder and CEO Nick Harris.

Lightmatter’s Photonics Revolution

The company’s comprehensive stack of photonics-enabled hardware and software solutions is strategically designed to decrease power consumption and enhance performance concurrently. This is particularly crucial for the ever-expanding realm of highly compute-intensive workloads, such as AI, which has become integral to critical industries worldwide.

“We are thankful for the support of our investors, each of whom shares our vision of Lightmatter playing an integral role in the future of computing. By increasing speed, lowering cost, and reducing environmental impact, our technologies can continue to push the limits of what’s possible, fueling greater AI adoption and innovation,” said Nick Harris.

Since its last funding announcement in May 2023, Lightmatter has experienced exponential growth, expanding its workforce by over 50 percent to meet burgeoning client demands and achieve key product milestones. Lightmatter will establish a Toronto office in 2024 in response to this expansion, underscoring its commitment to sustained growth and innovation.

Lightmatter fortifies its leadership team

Lightmatter has made strategic hires to fortify its leadership team, welcoming Danner Stodolsky as Vice President of Data Center Architecture and Colin Sturt as General Counsel.

Danner, previously Senior Vice President of Cloud at SambaNova and a Vice President of Engineering at Google, will spearhead the designing, simulation, and evaluation of large-scale systems based on Lightmatter’s groundbreaking technology.

With over 20 years of semiconductor industry experience, Colin will lead legal and compliance functions, supporting Lightmatter’s growth, intellectual property portfolio, and expansion of contractual relationships.

Lightmatter’s Leap in High-Performance Computing

Lightmatter’s commitment to revolutionizing computing, minimizing environmental impact, and propelling human progress is due to its photonics-enabled technologies.

These innovations have redefined how chips communicate and calculate, delivering photonic interconnect and compute products that simultaneously reduce power consumption and boost the performance of silicon powering advanced AI and HPC workloads.

“In the rapidly evolving landscape of generative AI, the demand for new compute and chip communication solutions is unprecedented. Lightmatter is harnessing the power of silicon photonics to meet this challenge, unlocking performance bottlenecks, increasing bandwidth, and allowing AI models to increase in size and scale,” said Erik Nordlander, General Partner at GV.
