Salience Labs Raises $125M With AMD Ventures, Intel Capital

Salience Labs, a photonic chip company founded in 2021 on research from the University of Oxford and the University of Münster, said on 14 October 2026 that it has completed an oversubscribed $125 million Series B round led by Bullhound Capital, with AMD Ventures and Intel Capital among the new investors.

The company says the money will accelerate deployment of its optical circuit switching technology, scale volume manufacturing and expand its presence in Silicon Valley.

What Salience Labs Announced

The release says Bullhound Capital Principal Callum Stewart joins Salience Labs’ board. Additional investors named are AMD Ventures, Intel Capital, SBI Group, Hudson River Trading and British Business Bank.

Existing shareholders that continued their support, according to the release, include Applied Ventures LLC, Oxford Science Enterprises, Cambridge Innovation Capital and Silicon Catalyst Ventures.

The release gives no valuation, no revenue figure and no named customers.

What the Chips Do, According to Salience

Salience describes an all-optical, fully integrated switch architecture built to connect thousands of GPUs across multiple racks for scale-up network performance in AI data centers.

The financing follows what the company calls its live demo of a 64-port all-optical photonic switch at ECOC 2026, which it describes as an industry first for silicon photonics optical circuit switching. It says the funding will enable 128- and 256-port switches.

“OCS will play a critical role in AI datacenter networking,” said Vaysh Kewada, CEO and co-founder of Salience Labs. “As customers roll out optical links in their datacenters, high-performance optical switches are needed to deliver the token economics that workloads demand.”

Why AMD and Intel Say They Invested

“AI infrastructure is increasingly being designed at rack scale, where networking has a direct impact on system performance, efficiency and economics,” said Patrick Rundell, Director, AMD Ventures, in the release.

“Photonics is quickly becoming essential to scaling AI infrastructure, and optical circuit switching can unlock significant gains in performance and efficiency,” said Srini Ananth, Managing Director at Intel Capital.

The release cites a Dell’Oro Group forecast that cumulative spending on data center switches in AI back-end networks will approach $1 trillion over 2026 to 2030, with scale-up projected to account for more than half of the market by 2030.

Manufacturing and Expansion

Salience says it will keep working with Keysight Technologies and Tower Semiconductor to scale manufacturing for high volume, and will open a second West Coast location as it builds out its Silicon Valley offices.

Earlier today we reported that Japan will fund up to $21 billion for two GlobalFoundries fabs, with GlobalFoundries also moving $955 million of its CHIPS award toward silicon photonics, silicon germanium and advanced packaging.

The Structural Read

As we read it, the investor list is the signal: the release names AMD Ventures and Intel Capital, two chipmakers’ venture arms, in the same round.

As we read it, the demo is the milestone the money follows: the release says the round comes on the heels of its 64-port all-optical switch shown at ECOC 2026.

As we read it, the spend Salience points to is large: it quotes Dell’Oro Group forecasting close to $1 trillion of AI back-end data center switch spending over 2026 to 2030.

Three Implications

GPU BUYERS Salience says its switch architecture is built to connect thousands of GPUs across multiple racks for scale-up performance.

CHIPMAKERS AMD Ventures and Intel Capital both invested, and both are quoted in the release on rack-scale networking and photonics.

MANUFACTURERS Salience says it will keep working with Keysight Technologies and Tower Semiconductor to scale to high-volume manufacturing.

The Business Engineer Lens

This story maps onto the Business Engineer framework The Nine Layers of AI.

The framework puts it this way: “It is a layered industrial stack — and at any given moment, the binding constraint sits at a different layer than it did six months ago.”

As we read it, Salience is pitching the networking layer as the one that binds next: its release says high-performance optical switches are needed to deliver the token economics AI workloads demand.

What Is Not Established

The release gives no valuation, revenue, customer names or shipment dates, and does not say how much each investor put in. Performance claims for the switch are the company’s own; we did not see the ECOC demo.

The Dell’Oro figure is a forecast quoted by Salience; we did not read Dell’Oro’s report.

The Bottom Line

Salience Labs raised an oversubscribed $125 million Series B led by Bullhound Capital, with AMD Ventures and Intel Capital among the investors, according to its 14 October 2026 release. It says the money funds 128- and 256-port optical circuit switches, volume manufacturing and a larger Silicon Valley presence.
