Company profile
researched Aug 2026Elastisys is a Swedish company that develops Welkin, a Kubernetes-based application platform aimed at organizations with strict requirements around control, compliance, and digital sovereignty. Welkin is built on Kubernetes and other cloud native technologies and is positioned as cloud-agnostic, able to run in public cloud, private cloud, on-premises, and air-gapped environments without vendor lock-in. The platform automates tasks such as security hardening and resilient infrastructure provisioning, and supports GitOps workflows, policy as code, and auto-scaling.
The company frames Welkin as a foundation for critical systems subject to regulatory regimes including NIS2, the Cyber Resilience Act (CRA), and ISO 27001, and markets it as a compliant environment for hybrid, multi-cloud, and edge deployments as well as for AI workloads handling sensitive data. Alongside the platform, Elastisys provides expert support and professional services covering platform migration, consulting, and instructor-led training in Welkin and Kubernetes (including Linux Foundation course material such as LFD459).
Founding story
According to the company, the impetus dates to 2011, when the team saw organizations across Europe struggling with complex infrastructure and difficult compliance requirements that diverted attention from innovation; the aim was to build a platform enabling organizations to operate modern applications in any environment.
Business model
Elastisys sells its Welkin platform in two delivery models: Welkin Enterprise, a self-managed deployment with vendor support and full administrative control for in-house DevOps teams, and Welkin Managed, a fully managed offering hosted on selected clouds with 24/7 monitoring and response plus automatic updates and scaling. Pricing is quote-based ("request pricing"). Add-on services include platform migration, consulting, Welkin training, and Kubernetes training. The company publishes a total-cost-of-ownership calculator comparing Welkin deployments against building and operating Kubernetes in-house, using inputs such as deployment model, support hours, CPU cores, and add-ons like PostgreSQL, Valkey cache, RabbitMQ, and ArgoCD GitOps.
Revenue is generated from platform license or service fees for Welkin Enterprise and Welkin Managed subscriptions, plus fees for migration, consulting, and training services.
Traction
The company's website presents customer testimonials from a healthcare-sector software vendor CTO using Welkin Enterprise, a chief architect at a B2B communication services provider using Welkin Managed, and participants in its training and consulting engagements.
