Each workload (model, agent, service) runs inside its own enclave with built‑in policy enforcement, default‑deny networking, short‑lived secrets, per‑workload messaging and end‑to‑end audit. ACRA is cloud‑agnostic and can run on AWS, Azure, on‑prem or air‑gapped. [valarian.com](https://www.valarian.com/) ## Market Standing - **Valuation / Market Cap**: Not disclosed (private company) - **Key Metric**: **Total Funding – $70M** (Series A of $50M led by New Enterprise Associates, bringing total to $70M) [valarian.com](https://www.valarian.com/) - **Notable Investors / Partners**: New Enterprise Associates (lead), plus “leading defence and national security investors”; also backed by operators from Palantir, Darktrace and US Special Operations. [valarian.com](https://www.valarian.com/about) - **Growth Signals**: Deployed across multiple continents; “100s of enclaves deployed”; headcount grew ~18.5% YoY (from 19 to ~24 employees); actively hiring across engineering, compliance and security roles. [linkedin.com](https://linkedin.com/company/valarian) ## Competitive Advantages - **Customer‑held keys**: Even Valarian cannot access customer systems after deployment — governance is enforced by the infrastructure, not by privileged access. [valarian.com](https://www.valarian.com/) - **Model‑independent**: Customers can run any model (open‑weight or frontier) without vendor lock‑in and without the model provider training on their data. [valarian.com](https://www.valarian.com/) - **Built by operators with real‑world experience**: The team includes backgrounds from US Special Operations, Palantir, Darktrace, secure communications and high‑assurance systems, giving them credibility in environments where failure has real consequences. [valarian.com](https://www.valarian.com/about) - **Air‑gap ready**: ACRA is cloud‑agnostic and can operate in disconnected, air‑gapped environments — a rare capability designed from day one for government/defence deployments. [valarian.com](https://www.valarian.com/) ## Strategic Focus - **Current priorities**: Scaling the platform for wider enterprise and government adoption; continuing to harden ACRA as the posture layer for AI workloads; expanding the team (engineering, security, compliance) to meet demand from regulated sectors. [jobs.lever.co](https://jobs.lever.co/valarian) - **Direction for growth**: Maintain “sovereign control” positioning — enabling customers to own their inference, data and access policies regardless of cloud or infrastructure substrate. ## Why Work Here - **Culture**: Hybrid work setup with a London HQ (flexibility where it matters, structure where it counts). [valarian.com](https://www.valarian.com/careers) - **Compensation & benefits**: Competitive compensation, equity, and employer‑enhanced pension contributions. [valarian.com](https://www.valarian.com/careers) - **Engineering environment**: Work on deep infrastructure (Kubernetes, SPIFFE/SPIRE, Cilium, Istio, Vault, NATS, OpenTelemetry) in a high‑trust, high‑impact domain that spans government, defence and regulated enterprise. Engineers are expected to own meaningful pieces of the platform from day one. - **Notable perks for job seekers**: Opportunity to work on a product that deals with cutting‑edge AI governance and national‑security‑grade isolation; small but growing team (24 people) where contributions are highly visible. ## Sources 1.
