Salience Labs raised $30 million in a Series A led by ICM HPQC Fund and Applied Ventures, with Braavos and existing backers joining the round. The funding was reported as support for its optical switch push into AI data-center infrastructure.
Salience Labs says it launched the industry's highest-performing 32-port all-optical silicon photonic switch for AI datacenter networking. The product targets the data-movement bottleneck inside AI clusters and is positioned for large-cluster connectivity.
Salience Labs and Tower Semiconductor announced a manufacturing partnership for the company's optical switch technology in February 2026. Tower said AI workloads are driving unprecedented growth in data-center scale and network complexity, lifting demand for higher bandwidth and lower latency.

Pre-IPO investments carry significant risks. Salience Labs shares are illiquid, meaning there is no public market to sell them quickly. There is no guaranteed exit timeline or return. The investment is speculative in nature, and investors should be prepared for the possibility of total loss. Valuations of private companies can fluctuate substantially between funding rounds. Investors should consult their financial advisor and review all offering documents before investing.
In a pre-IPO transaction, accredited investors purchase shares from existing shareholders (such as employees, early investors, or other holders) through secondary market platforms. The company itself does not issue new shares in these transactions. UpMarket facilitates these trades as a FINRA-registered broker-dealer, handling compliance, documentation, and settlement on behalf of both parties.
There are two primary exit paths for pre-IPO holdings: selling your shares on the secondary market to another buyer, or holding until the company completes an IPO or is acquired. Both paths are subject to transfer restrictions, company approval (right of first refusal), and market conditions. The timing of any exit is unpredictable, and investors should plan for a multi-year holding period.
The minimum investment for most pre-IPO offerings on UpMarket is $50,000. This amount may vary depending on the specific offering and share availability. There are no fees to create an UpMarket account or browse available investments. Investors only pay transaction-related fees when they complete an investment.
UpMarket's valuation estimate of is derived from a proprietary model that incorporates multiple data sources: funding round data (Caplight), revenue estimates (Sacra), secondary market pricing, and public company comparables. The model applies a private company discount to the public comp multiple to account for illiquidity and information asymmetry. This estimate is not investment advice and may differ substantially from the price at which shares actually trade.
