About Ænix

The open-core company that created Cozystack

Ænix is an open-core company with two legal entities: AENIX s.r.o. in the Czech Republic for EU contracts and AENIX INC in Delaware, USA, for US contracts. About 20 people work in the EU and Central Asia. Ænix created Cozystack, a CNCF Sandbox project licensed under Apache 2.0, and is one of its maintainers together with maintainers from other companies. On top of Cozystack, Ænix sells three platforms: Ænix Public Cloud Platform for hosting providers and other organisations selling cloud, Ænix Private Cloud Platform for enterprises replacing VMware and running cloud for themselves, and Ænix AI Platform for GPU and AI workloads. It also sells enterprise support for teams that run Cozystack themselves. AENIX s.r.o. holds ISO/IEC 27001:2022 certification.

What we do

We build cloud platforms for organisations that need real cloud infrastructure on their own terms — for regulatory reasons, commercial reasons, or both.

Our customers fall into a few buyer profiles, each matched by a platform:

  1. Hosting providers, MSPs and regional clouds (Public Cloud Platform) — providers modernising beyond VPS and adding managed Kubernetes, databases, object storage and GPU to their price list
  2. National clouds, telcos and other operators at scale (Public Cloud Platform) — multi-region commercial clouds
  3. Regulated enterprises (Private Cloud Platform) — banks, insurers, public administration, telcos and healthcare replacing VMware under DORA, NIS2 and sovereignty mandates; developer self-service is included
  4. AI-heavy organisations and GPU clouds (AI Platform) — companies running inference and training on their own GPUs, and providers selling GPU capacity

Plus enterprise support for Cozystack for teams running the open-source project on Hetzner, OVH or leased bare metal who want the maintainers on call.

Every support tier includes the proprietary Ænix commercial modules (billing system and WHMCS integration). The price list, from $1,250 per month per 10 nodes, is the Ænix Public Cloud Platform subscription; a team running Cozystack itself buys the same subscription and can simply leave the commercial modules unused. Private Cloud Platform and AI Platform programmes are quoted per RFP. See pricing.


Why open core

We created Cozystack as an open-source CNCF project because cloud infrastructure that aims to be sovereign, auditable and customer-controlled must be built on a foundation customers can verify and own:

  • Auditable end-to-end — an open-source supply chain you can assess under DORA Article 28 (ICT third-party risk) and NIS2 Article 21(2)(d) (supply-chain security)
  • Customer-controlled — your hardware, your jurisdiction, your encryption and retention policies
  • Vendor-neutral at the foundation — no architectural lock-in to Ænix
  • Long-horizon viable — the Apache 2.0 licence outlives any single commercial vendor

The Ænix platforms are the commercial layer for organisations that need a complete cloud product (hosting panel, billing, portals, payments, support, productized installer) without building it themselves. The open-source foundation remains free for anyone to run.

This is the open-core model, as with Confluent on Kafka or GitLab CE/EE: the open project keeps its integrity, and the commercial product adds billing, portals, support and delivery on top.


Cozystack and CNCF

Cozystack is a CNCF Sandbox project. Its CNCF Incubation application, filed in October 2025, is in due diligence with the CNCF Technical Oversight Committee.

  • Conformance: CNCF Certified Kubernetes distribution; accepted into the CNCF Kubernetes AI Conformance programme in September 2026 — see the Kubernetes conformance evidence
  • Architecture: Talos Linux + Kubernetes + KubeVirt + Cilium + LINSTOR + Tenant CRD + Cozystack Dashboard + VictoriaMetrics + VictoriaLogs
  • Licence: Apache 2.0 — anyone can run it
  • GitHub: github.com/cozystack/cozystack
  • Documentation: cozystack.io/docs — vendor-neutral project documentation
  • Community: #cozystack on Kubernetes Slack, Telegram, GitHub
  • Maintainers: Ænix engineers together with maintainers from other companies, plus community contributors

Per CNCF community norms, cozystack.io stays vendor-neutral — no commercial calls to action and no funnel links to aenix.io. The boundary protects long-term community trust.


Certifications

  • ISO/IEC 27001:2022 — AENIX s.r.o., certificate SIC.MS.008.ISO/IEC27001.5719, valid through 26 February 2027. Certificate details and scope →
  • CNCF Certified Kubernetes and CNCF Kubernetes AI Conformance — for Cozystack, the engine of all three platforms. Evidence →
  • There is no SOC 2 report. The platforms themselves are not certified; they supply controls and evidence for your own ISO 27001, DORA, NIS2 and GDPR work. Compliance evidence →

Our story

Our story

We started as a team of platform engineers building cloud infrastructure for service providers and regulated enterprises. The pattern we kept seeing: customers wanted a real cloud (multi-tenant, billing, portals, GPU, managed services) but did not want hyperscaler dependency or VMware lock-in. The existing open-source options (raw Kubernetes, OpenStack at scale) required years of platform-engineering investment most customers couldn’t make.

So we built Cozystack — a Kubernetes-native multi-tenant cloud platform — as the foundation we wished we’d had years earlier. It became a CNCF project. Then we built the commercial layer on top, as three platforms matched to who consumes the capacity.

Cozystack runs in production at hosting providers and regional clouds, and Ænix delivers platform engagements for banks under NDA. Nine case studies are published with architecture and figures, anonymised where contracts require it.


How we engage

Ænix engagements typically follow this sequence:

  1. Discovery call (free, 30 min) — confirm fit, scope, regulatory context and which platform matches
  2. Platform Readiness Assessment (14 days focused or 28 days full, fixed price) — current-state audit, gap analysis, platform recommendation, migration roadmap
  3. Launch or build — Public Cloud Platform at provider scale goes live in weeks once hardware is ready, with the productized installer. Private Cloud Platform: a 3–12 month build depending on scope. Multi-region national or operator programmes: a 3–6 month pilot, then 9–18 months to full multi-region
  4. Managed operations (ongoing retainer) — optional after deployment

For governments and sovereign cloud builders, engagements run through public-sector procurement (RFI / RFP) and are priced through the procurement process itself.

Ænix is the open-core company that created Cozystack — a CNCF project (CNCF Sandbox; CNCF Incubation application in due diligence), Apache 2.0 — and builds the three Ænix platforms on it.

Frequently asked questions

What does Ænix do?

Ænix builds and supports cloud platforms on Cozystack: a public cloud for hosting providers and other organisations selling cloud, a private cloud for enterprises replacing VMware, and an AI platform for GPU workloads. It also sells enterprise support for teams that run open-source Cozystack themselves.

Where is Ænix based?

AENIX s.r.o. is registered in České Budějovice, Czech Republic, and handles EU contracts and EU public-sector procurement. AENIX INC is registered in Delaware, USA, and handles US contracts. The team of about 20 people works in the EU and Central Asia.

Who founded and leads Ænix?

Ænix was founded by Andrei Kvapil and Timur Tukaev. Andrei Kvapil is CEO and Timur Tukaev is COO.

Is Cozystack an Ænix product?

No. Cozystack is a CNCF project under Apache 2.0. Ænix created it and is one of its maintainers, with maintainers from other companies. What Ænix sells is a subscription — support, commercial modules such as billing and the WHMCS integration, and engineering services — not a licence to Cozystack.

Does Ænix hold any certifications?

Yes. AENIX s.r.o. holds ISO/IEC 27001:2022 for its information security management system, valid through 26 February 2027 — see the ISO 27001 page. There is no SOC 2 report. Cozystack is a CNCF Certified Kubernetes distribution and was accepted into the CNCF Kubernetes AI Conformance programme in September 2026.

Why three platforms and not one?

Because the commercial surface differs, not the technology. Selling capacity to customers needs billing, payments, a customer portal and tenant suspension. Running cloud for your own organisation under a regulator needs audit logging, air-gapped installs, control mapping and developer self-service. Running GPUs needs allocation, sharing and per-tenant usage measurement. One engine, three surfaces — and they combine.

How big is Ænix, and can it support a large programme?

About 20 people. The platform is a product, so a large build is mostly configuration and migration rather than bespoke construction, and the engineers who maintain Cozystack upstream are the ones who work on customer clusters. For a large programme Ænix staffs a named delivery team for each phase.
