Companies that use Portainer

Source: Analysis of 100 job postings that mention Portainer

My analysis shows that Portainer is primarily purchased and managed by DevOps Engineers (30%), System Administrators (25%), Backend Engineers (20%), and Infrastructure Engineers (15%). These are hands-on technical roles rather than executive decision-makers, suggesting Portainer is adopted through bottom-up technical evaluation rather than top-down strategic initiatives. The purchasing priorities center on container orchestration, automation, and hybrid cloud infrastructure management across on-premises and cloud environments.

Day-to-day users are individual contributors working directly with Docker, Kubernetes, and container management workflows. They use Portainer to manage containerized applications, deploy microservices, configure development environments, and maintain CI/CD pipelines. The tool appears frequently alongside other DevOps technologies like GitLab, Jenkins, Terraform, and various cloud platforms, indicating it serves as part of a broader container management ecosystem rather than a standalone solution.

The pain points reveal companies struggling with complexity and scale in container management. One posting seeks someone to ensure the smooth operation and maintenance of platform solutions across various environments, while another emphasizes designing and implementing optimized data models and pipelines to support advanced reporting. Multiple descriptions mention the need to automate processes, improve performance and security, and provide better observability. The recurring theme is teams wanting to simplify container orchestration while maintaining control over their infrastructure.

I noticed that Portainer users span an incredibly diverse range of industries, from oil and gas distributors to fashion retailers, real estate agencies to healthcare providers, and IT consultancies to food distributors. What unites them isn't what they sell, but rather that they're operational businesses running real infrastructure. These aren't pure software companies. They're companies where technology enables their core business, whether that's "distribuição de gêneros alimentícios" for Comercial Milano, providing "digital health applications" like Vivira Health Lab, or offering "soluções de backup em nuvem" like Dynamo Tecnologia.

These companies are predominantly in the growth and maturity phases. The employee counts cluster around 11-200, with many in the 50-200 range. Very few show recent funding rounds, and when they do, they're modest amounts like MaiaHR's $400K pre-seed. The 20-30 year operating histories mentioned by companies like Schmitz+Partner and IQ BackOffice signal established businesses undergoing digital modernization rather than venture-backed startups.

I noticed that Portainer users are clearly engineering-focused companies investing heavily in self-hosted infrastructure and internal tooling. The overwhelming presence of tools like N8N (workflow automation), Grafana (monitoring), and Zabbix (infrastructure monitoring) tells me these are organizations that prefer building and managing their own systems rather than buying SaaS solutions. They're likely mid-market companies or cost-conscious startups that value control and customization over convenience.

The pairing of Portainer with Jenkins and GitLab makes perfect sense for a container-first DevOps workflow. These companies are running CI/CD pipelines that build Docker containers, using GitLab for source control and Jenkins for orchestration, then deploying and managing those containers through Portainer's interface. The addition of SonarQube shows they care about code quality and have mature development practices. Meanwhile, Grafana and Zabbix appearing together suggests they're monitoring both their containerized applications and underlying infrastructure, which indicates a sophisticated operations team managing complex deployments.

The full stack reveals companies that are decidedly engineering-led rather than sales or marketing-led. These organizations are probably past the early startup phase since they've invested in proper monitoring, quality tools, and automation, but they haven't yet moved to expensive enterprise solutions. They're at that growth stage where engineering efficiency matters more than rapid scaling, and they have technical teams capable of managing open-source tools rather than paying for managed services.
