What AT Computing does

AT Computing is a Netherlands-based IT training and consultancy firm founded in 1985, focused exclusively on open source technologies. The company delivers instructor-led training courses spanning Linux/UNIX administration, DevOps toolchains (Docker, Kubernetes, Ansible, Terraform, HashiCorp Vault), programming languages (Python, C, C++, Fortran), and emerging GenAI/LLM deployment topics. Training is delivered through AT Cloud Labs, a proprietary browser-accessible hands-on lab environment with GPU support, alongside the AT Computing Academy learning platform that hosts course materials, slides, and exercises. The company also provides expert advisory services covering digital sovereignty, open source strategy, and GenAI implementation.

The firm operates through two legal entities under parent Complementair Groep: AT Computing B.V. handles all training activity under director Marcel Kornegoor, while AT Experts B.V. delivers secondment and consultancy services under director Dennis Kruyt. All public and in-company training enrollment is routed exclusively through sister company Vijfhart IT-Opleidingen, while consultancy is sold directly to organizations per half-day, per project, or via prepaid "strippenkaart" session cards. Workshops are priced at discrete rates (e.g., 999 EUR per HashiCorp Boundary workshop), and longer training programs run at per-day unit pricing.

AT Computing positions itself as vendor-independent and serves two primary customer segments: individual IT professionals and developers seeking to upskill in open source technologies, and organizations requiring bespoke training aligned with their environments or vendor-independent strategic advice on digital sovereignty and GenAI adoption. The team comprises 15 specialized open source "gurus," and the firm maintains strategic partnerships with The Linux Foundation (for official Kubernetes certification pathways) and the Dutch Open Source Business Alliance.

Scale indicators2 records

Expansion highlights5 records

Broad incumbents

• Global Knowledge: One of the world's largest IT training providers offering vendor-authorized courses across AWS, Microsoft, Google, Cisco, and open source technologies. Comparable as a premium instructor-led IT training provider for enterprise customers, but with much broader portfolio and global delivery scale.
• A Cloud Guru (Pluralsight): Large online technology learning platform covering cloud, DevOps, security, and AI. Comparable on cloud and DevOps curriculum scope, subscription-priced and self-paced, representing the online alternative AT Computing must differentiate against for self-directed learners.
• Red Hat Training: Official training arm of Red Hat offering vendor-specific Linux, Ansible, OpenShift, and Kubernetes courses. Comparable on the Linux and DevOps curriculum axis, but vendor-locked and premium-priced, providing AT Computing an opening as a vendor-neutral alternative for organizations seeking multi-vendor open source training.
• SUSE Training: Official training provider for SUSE Linux Enterprise and Rancher Kubernetes management. Comparable on the Linux and Kubernetes curriculum axis, vendor-locked to SUSE/Rancher, complementing AT Computing's vendor-neutral positioning for enterprise customers standardizing on SUSE.
• New Horizons Computer Learning Centers: Global IT training franchise delivering vendor-authorized and general IT courses to enterprise and individual learners. Comparable as a multi-vendor IT training operator, but US-headquartered and broader in scope, while AT Computing is open source-specialized and Netherlands-anchored.

Direct peers

• Vijfhart IT-Opleidingen: Sister company and exclusive distribution channel for AT Computing's training courses. Offers a broader IT training catalog across vendors and technologies but shares training DNA, target audience (Dutch IT professionals), and corporate parent (Complementair Groep). Direct comparison point for channel economics and curriculum overlap.

Others

• DevOpsDays Netherlands / Open Source community events: Community-driven open source and DevOps event ecosystem in the Netherlands and Europe where AT Computing's 'gurus' present and recruit. Relevant as the grassroots community channel that shapes demand for AT Computing's paid training and consultancy, rather than a direct commercial competitor.

Emerging players

• The Linux Foundation: AT Computing's strategic partner and the dominant provider of Linux and Kubernetes training globally, including official CKAD/CKA certification prep. Comparable as a Linux/Kubernetes training authority, but operates at much larger scale and offers free or low-cost e-learning that competes with AT Computing's paid classroom model.
• KodeKloud: Online DevOps and cloud training platform specializing in hands-on labs for Docker, Kubernetes, Ansible, Terraform, and CI/CD. Comparable on the DevOps curriculum axis, but delivers at low price points via subscription, representing the online-native competition against AT Computing's classroom model.

Regional players

• HappyStack / Computrain: Dutch IT training providers (Computrain is part of the same NCOI group ecosystem) offering IT and business training in the Netherlands. Direct regional peers competing for the same Dutch IT professional audience, but with broader portfolios including project management and business skills alongside technical courses.
