Lead Investor: T. Rowe Price

Lightmatter’s primary product is called "Passage," a next-generation optical networking solution that leverages silicon photonics.

Passage accelerates data transmission between data center chips by reducing the number of networked switches typically required. GPUs spend a significant amount of time idle, waiting for data to pass through a hierarchy of network switches. Passage flattens this hierarchy, enabling faster data transfer by connecting GPUs through ultra-dense optical fibers that offer bandwidth speeds up to 100 terabits per second—100x faster than current data center capabilities.

Tako sources their data in real-time from authoritative, vetted providers and supports single-domain searches (e.g. “Nvidia stock price”), cross-domain searches (e.g. “Nvidia stock price vs. Biden approval rating”), and time-based searches (e.g. “Nvidia stock price vs. Biden approval rating since 1/11/22”) across a range of financial, economic, and political data.

Tako can also be integrated into other platforms via API, as demonstrated by its partnership with Perplexity.
