Our take
Neural networks and CPUs are vital to AI solutions, but manufacturers have largely failed to maintain innovation in recent years. Lightmatter solves this problem by offering a next-generation computing platform powered by photonics (light waves).
Lightmatter offers a forward-facing platform for AI-building that acts as an alternative to traditional solutions. It works by replacing wired CPUs with a combination of photonics and new algorithms. Lightmatter's solution is not only faster, but it is considerably more sustainable, and it has the potential to drive the next generation of AI development.
As of 2025, Lightmatter has raised $850 million across six funding rounds and grown to a staggering valuation of $4.4 billion, a testament to growing industry demand for faster, more effective AI-building solutions. Lightmatter currently has three products on the market - Envise, Passage, and Idiom - and is poised to take on the incumbent chiplet industry with a photonics-based alternative.
