What Is nexos.ai?

Teams that switch away from OpenRouter usually cite one of two reasons: they want governance controls OpenRouter doesn't offer, or they want their AI traffic to sit under EU rather than US jurisdiction. nexos.ai answers both at once. The Vilnius-based platform gives enterprises a single gateway to more than 200 AI models, wrapped in guardrails, observability, and access controls that a routing API alone doesn't provide.

Tomas Okmanas and Eimantas Sabaliauskas founded the company in 2024. They're the pair behind Nord Security, the group that built NordVPN into one of the best-known consumer security brands in Europe. That pedigree matters here — nexos.ai isn't a weekend side project chasing the AI wave, but a security-first team applying access-control instincts from VPN infrastructure to enterprise AI adoption.

Spectra Tech, UAB, registered in Vilnius, is the legal entity behind the product. It raised a €30 million Series A in October 2025, led by Evantic Capital with participation from Index Ventures. Earlier backers Creandum and Dig Ventures also joined, reportedly valuing the company at around €300 million just six months after launch. Two connected surfaces make up the product: an AI Workspace for employees who chat with models directly, and an AI Gateway for developers who need programmatic access with policy enforcement built in.

Key Features

AI Gateway and model routing

Every supported model routes through a single OpenAI-SDK-compatible endpoint. If your codebase already calls the OpenAI SDK, pointing it at nexos.ai requires no re-architecting — you swap the base URL and keep the rest of your integration intact. Behind that endpoint, nexos.ai handles smart routing by cost or latency, prompt caching to cut repeat-query spend, and centralised API key management across every provider you connect.

Guardrails and access control

This is where nexos.ai earns its "governed" positioning. The platform scans prompts and outputs for personally identifiable information, payment details, and confidential business terms, applying custom enforcement logic that can redact or block a request outright. Role-based access control determines which teams can reach which models, and policy enforcement runs centrally rather than per-integration. For a security-conscious buyer comparing this to raw OpenRouter access, the guardrails layer is the entire pitch.

Observability

Every prompt, output, token count, and triggered guardrail gets logged into a real-time dashboard. Compliance and security teams can review usage patterns, spot latency spikes, or catch runaway spend before it becomes an unexplained budget line. It also produces audit trails for regulatory review, a genuinely useful capability as the EU AI Act's documentation requirements start biting for general-purpose AI system deployers.

AI Workspace

For non-technical staff, the Workspace behaves like a governed ChatGPT: a chat interface over the same 200+ models, with the same guardrails applied automatically. It integrates directly into Slack and Microsoft Teams, with a Home Tab, sidebar, and right-click shortcuts that let people summarise a thread or turn a message into a task without leaving the conversation. Salesforce, Google Workspace, and SharePoint connections extend that into sales and document workflows.

RAG and agents

nexos.ai also offers retrieval-augmented generation grounded in a company's own documents, and no-code AI agents aimed at sales teams that need to pull from Salesforce or Slack context automatically. These feel newer and less battle-tested than the core gateway, but they signal where the roadmap is heading — from routing infrastructure toward a fuller AI operations layer.

Pricing

nexos.ai's Pro plan runs €20 per user per month billed annually, or €25 billed monthly — public pricing, which is unusual for an enterprise AI gateway and worth crediting. A 7-day free trial with €5 of model credits requires no credit card, and every plan carries a 14-day money-back guarantee.

The catch sits in the usage layer. Model calls carry a platform fee added on top of whatever the underlying provider charges — the company's own example is a model priced at $10 per million tokens costing $10.50 through nexos.ai. That markup buys governance, routing, and observability, and for teams juggling several providers manually, it can still net out cheaper than the engineering time saved. But heavy single-provider users comparing nexos.ai against going direct should run the token-volume math first, because the fee compounds at scale.

Enterprise pricing is custom and requires 50 or more seats, adding SSO/SAML, RBAC, audit logs, and dedicated support with negotiated commercial terms.

EU Compliance and Privacy

nexos.ai's clearest structural advantage is jurisdiction. Spectra Tech, UAB is registered in Vilnius, Lithuania, and the company states its infrastructure is GDPR-compliant. Its public Trust Center lists SOC 2 Type 2, ISO/IEC 27001:2022, and ISO/IEC 42001:2023 as achieved certifications, each with a downloadable report. That combination puts data processing under EU law by default, which matters for organisations that have spent years untangling Schrems II-driven concerns about routing sensitive prompts through US infrastructure.

The certification stack is unusually complete for a company this young, and the ISO/IEC 42001 credential specifically speaks to AI-management governance rather than general information security. What remains a fair diligence question is the company itself: nexos.ai launched in 2024, so buyers should still ask about roadmap continuity and enterprise pricing directly, since procurement details beyond the Pro tier stay behind a sales conversation.

Who It's Best For

Enterprise IT and security teams replacing an ungoverned patchwork of employee ChatGPT accounts with something they can log, restrict, and audit. If shadow AI usage is the actual problem you're solving, the Workspace plus guardrails combination is the strongest reason to choose nexos.ai over a plain routing API.

European compliance-conscious buyers who want AI infrastructure under EU jurisdiction without giving up model choice. Choose nexos.ai if data residency and audit trails matter more than shaving cents off token pricing.

Developers currently on OpenRouter who need RBAC, guardrails, or audit logging that a pure routing API doesn't provide. If you only need cheap, unrestricted model access, nexos.ai's platform fee makes less sense — go direct instead.

Teams wary of early-stage vendor risk should proceed carefully. A €30 million Series A and Nord Security pedigree reduce but don't eliminate the risk that comes with a company founded in 2024.

The Verdict

nexos.ai solves a real problem: enterprises want the flexibility of multi-model access without losing visibility into what employees and applications are actually sending to those models. The guardrails, observability, and Workspace-plus-Gateway combination genuinely differentiate it from a bare routing API, and the Vilnius HQ gives EU buyers a jurisdictional answer that OpenRouter cannot offer. Real trade-offs remain, though — a young company, a token-price markup that adds up at volume, and Enterprise pricing that stays behind a sales call. Governance-first buyers will find those acceptable costs. Teams chasing the cheapest possible tokens should look elsewhere, perhaps at Mistral AI directly for a single-vendor EU option, or at self-hosted routing through tools in the broader AI developer tools category.

Frequently Asked Questions

Is nexos.ai GDPR compliant?

Yes. nexos.ai is operated by Spectra Tech, UAB, registered in Vilnius, Lithuania, and processes data under GDPR. Its Trust Center lists SOC 2 Type 2, ISO/IEC 27001:2022, and ISO/IEC 42001:2023 certifications, with audit logging of prompts and guardrail actions for compliance review.

How is nexos.ai priced?

The Pro plan costs €20 per user per month billed annually, or €25 billed monthly, covering the full AI Workspace and AI Gateway. Model usage carries a platform fee on top of the underlying provider's token price. Enterprise pricing is custom, typically starting at 50 seats.

How does nexos.ai compare to OpenRouter?

OpenRouter is a US-based model-routing API aimed mainly at developers. nexos.ai adds an employee-facing workspace, guardrails, RBAC, and audit logging on top of gateway routing, operating under EU jurisdiction rather than US law.

How many AI models does nexos.ai support?

More than 200 AI models are reachable through one OpenAI-SDK-compatible endpoint, letting teams switch providers or route by cost and latency without rewriting application code.

Who founded nexos.ai and how is it funded?

Tomas Okmanas and Eimantas Sabaliauskas, the co-founders of Nord Security, founded nexos.ai in 2024. The company raised a €30 million Series A in October 2025, led by Evantic Capital with Index Ventures, Creandum, and Dig Ventures participating.
