Perplexity Partners With Valarian on Sovereign AI

Perplexity has partnered with Valarian, a London-based sovereign infrastructure company, to let organisations run Perplexity’s AI tools inside their own computing boundaries. Under the deal, which Valarian announced on 20 October 2026, Perplexity’s “answer, research and discovery capabilities run under the customer’s own policy, against the customer’s own data, on compute the customer chooses.”

The deal targets the governments, banks, defence organisations and infrastructure operators that have been wary of sending sensitive work to an externally run AI service. Neither company gave pricing, a customer count or an availability date.

In brief

Perplexity’s AI tool suite will be deployed through ACRA, Valarian’s sovereign execution environment, on infrastructure the customer chooses.
Valarian says that compute can be the customer’s cloud, dedicated GPUs, multiple clouds or hardware the organisation physically owns.
No pricing, customer numbers or launch date were given.

How it works

Valarian describes two layers. Perplexity provides the “experience layer”: the agent harness, tools and interaction model. Valarian provides the execution layer: policy, runtime boundaries, workload orchestration and compute.

Through ACRA, organisations can serve and swap models, choose the tools they deploy, and set policies on what agents can access. Valarian gives an example: one group of agents could call frontier models through external APIs for low-sensitivity research, while another runs inside an isolated enclave against a local model with access to confidential data. Both would sit under the same control layer.

Perplexity published a blog post on the partnership the same day.

What the companies say

“The first era of enterprise AI was about access. Organisations raced to put intelligence in front of their people, and most did it by renting someone else’s environment,” said Max Buchan, Valarian’s chief executive and co-founder. “The next era will be about owning your intelligence, and this partnership gives the institutions that need it most a way to start now.”

Nate Kupp, Perplexity’s vice president of engineering for enterprise and infrastructure, said: “Perplexity’s enterprise customers are concentrated in industries where the data is the business: finance, science and law. For many of them, the usefulness of AI was settled a long time ago. What’s held them back is where it runs and who controls it.”

Joseph Clifford, chief technology officer at diagnostics company Randox, said in the release that Valarian’s product is “a key fit for peace of mind” for securing patient data.

Who Valarian is

Valarian was founded by Max Buchan and Josh McLaughlin and serves enterprise and defence customers. In July 2026 it raised a $50 million Series A led by New Enterprise Associates, bringing its total funding to $70 million, the release says. Perplexity, founded in 2022, says it answers more than 1.5 billion questions a month; that is its own figure.

Our read

Running a popular AI product inside a customer’s own boundary is fast becoming the price of entry for regulated buyers. The deal gives Perplexity a route into sovereign deployments without building that layer itself, and gives Valarian a well-known product to run on its platform. Without prices, customers or dates, though, it is still an architecture announcement rather than proof of adoption.
