Valarian
Valarian builds ACRA, a control layer that lets governments and regulated enterprises run AI and mission-critical workloads on any compute — cloud, on-premises, air-gapped or tactical edge — while holding their own keys and jurisdiction.
Background
Max Buchan founded the company in London in 2020, incorporating it in November 2019 under the name Worldr. His starting point was not defence at all.
After a stint as the first employee at digital asset manager CoinShares, he set out to build a private alternative to Slack and Microsoft Teams, then pivoted from the messenger itself to the layer underneath it: a zero-trust wrapper that kept corporate communications inside the customer's own environment rather than a vendor's. Regulated finance was the first market. The company renamed itself Valarian Technologies in November 2023.
Defence arrived through the door rather than by design. A US government customer asked whether the platform could be extended to national sovereignty, and Josh McLaughlin — a former US Army Ranger and Palantir managing director who opened the firm's Doha office — joined as co-founder and COO in 2023 to build that side out.
Valarian Defence launched publicly in May 2025. The business now runs two tracks, Enterprise and Defence, on one platform. Nick Trim, Darktrace's co-founder and former COO, chairs the board.
Financial footing
- The $50M Series A lead is confirmed and correct
- Valarian announced $50 million in Series A funding on 13 July 2026, led by New Enterprise Associates with participation from Lightbank, XTX Markets, Sequel and LitVC, plus angel investors Nikesh Arora and Gokul Rajaram
- NEA describes it as its first defence and dual-use investment in Europe
- Total raised is $70 million
- No valuation was disclosed
- The prior funding history sits largely under the company's former name, Worldr: a £280,000 InnovateUK grant, a $3 million seed in July 2021 led by IQ Capital and Playfair Capital, and an $8 million round in November 2022 led by Molten Ventures, taking seed funding to $11 million
- A further $7 million strategic tranche co-led by Scout Ventures and Artis Ventures landed in May 2025 alongside the stealth exit
- The company states this brought total seed to $20 million, though the individually disclosed tranches sum to $18 million
- On customers, no named contract, agency or programme has been disclosed at any point
- The company references NATO member states, banks, pharmaceutical firms and airlines, and an early US government contract that prompted the creation of Valarian Defence, but names none of them and discloses no contract values
- Its only publicly named commercial relationship is a February 2026 strategic partnership with Second Front Systems, integrating Second Front's Game Warden platform with ACRA for UK and European defence deployments
- CEO Max Buchan stated in a July 2026 podcast interview that the company signed $43 million in contracts in a single quarter and expects roughly $100 million this year
- That figure is unaudited, single-sourced to the founder, and is not corroborated by any filing or third party
- Backers: New Enterprise Associates (Series A lead, partner Mustafa Neemuchwala), with Lightbank, XTX Markets, Sequel and LitVC/Litquidity Ventures participating, plus angels Nikesh Arora and Gokul Rajaram. Earlier backers include Scout Ventures and Artis Ventures (co-leads of the 2025 strategic seed tranche), Molten Ventures, IQ Capital, Playfair Capital, MD One Ventures, Pretiosum Ventures, Navigate VC and CyLon.
Valarian is private, venture-backed and founder-led, with $70 million raised across its life. The July 2026 Series A of $50 million, led by NEA, is the bulk of it. Lightbank, XTX Markets, Sequel and LitVC joined, alongside angel cheques from Palo Alto Networks chief executive Nikesh Arora and Gokul Rajaram. Before that, under the Worldr name, came a £280,000 InnovateUK grant, a $3 million seed in 2021 led by IQ Capital and Playfair Capital, and $8 million in November 2022 led by Molten Ventures.
A $7 million strategic tranche co-led by Scout Ventures and Artis Ventures closed in May 2025. The company puts total seed at $20 million; the disclosed tranches add to $18 million. No valuation has ever been published, and no revenue figure has been filed or independently verified. Headcount was reported at roughly 31 around the Series A.
Major customers & contracts
No customer, contract or programme has been named publicly — not one, at any stage. This is the single largest gap in the record. The company describes serving NATO member states through Valarian Defence and banks, pharmaceutical companies and airlines through Valarian Enterprise, and its own site claims hundreds of enclaves deployed across four continents, but every one of those references is unattributed. An early US government contract is credited with prompting the creation of the defence division; the agency and value are undisclosed.
The one publicly named relationship is commercial rather than a customer: a February 2026 strategic partnership with Second Front Systems, pairing Second Front's Game Warden accreditation pipeline — itself assured by the UK Ministry of Defence and NATO — with ACRA, aimed at speeding sovereign software into classified UK and European environments. No public award notice naming Valarian appears in UK or US defence procurement records.

Competitive position
Palantir is the named incumbent, and Valarian's entire investment case is built on European discomfort with it — contested UK NHS and MoD deals, a French move to cut ties, stalled entries in Germany and Switzerland. Valarian's architectural edge is that it grants itself no privileged access: keys stay with the customer, deployments are cryptographically unique, and the vendor cannot reach in after launch. Its weakness against Palantir is scale and proof.
Palantir has two decades of delivery, an ontology layer and named programmes; Valarian has roughly 31 staff and, by its own lead investor's description, still has to build the data platform, ontology and application suite. Against the hyperscalers' sovereign-cloud regions from AWS, Microsoft and Google, Valarian's advantage is that it runs above all of them and works air-gapped; the risk is that those same providers are its substrate and can absorb the governance layer.
Battlefield relevance
ACRA is explicitly engineered for austere conditions. It is designed to stand up in minutes, runs on GPUs packed into a ruggedised transit case connected over Starlink or a local network, operates air-gapped, and is built to keep functioning on degraded links — capabilities packaged as ACRA EDGE.
The company says the platform is proven at the edge on portable GPU clusters as well as in cloud and on-premises estates. What is missing is any independent account of it being used. No named exercise, theatre, unit or operational deployment has been disclosed, and no third party has documented ACRA running in a live military operation. No confirmed combat use to date.
