IT consulting and custom software delivery for enterprise modernization
Keystone Solutions pairs IT strategy and software engineering to help enterprises migrate and modernize legacy systems. The tech stack—Java, Spring Boot, Kafka, Docker, Kubernetes—reflects a strong infrastructure-as-code discipline; active adoption of Prisma Access/Cloud and Azure Kubernetes Service signals a pivot toward zero-trust security and container orchestration at scale. Hiring velocity is accelerating with a 19:8 engineering-to-ops ratio and a senior-heavy mix (23 of 40 roles), indicating they are ramping execution on complex cloud and security migrations rather than scaling sales.
Notable leadership hires: Java Technical Lead
Keystone Solutions is an IT services firm based in Brussels founded in 2014, operating with 51–200 employees. The company delivers four service lines: hyperautomation (RPA, AI, ML-driven process optimization), IT consulting (architecture and digital transformation strategy), custom software development, and IT security (risk assessment, incident response, compliance). Core projects center on legacy modernization—monolithic-to-microservices refactoring, on-premises-to-cloud migration, zero-trust network implementation—and workflow automation (digitizing manual processes, centralizing authorization tracking). Clients are mid-to-large enterprises in regulated industries (financial services, public sector) managing significant technical debt and compliance complexity.
Keystone uses Java, Spring Boot, Kafka, Docker, Kubernetes, Azure, AWS, and GCP. Security tools include Palo Alto Networks and Cisco. They actively adopt Prisma Access/Cloud and Azure Kubernetes Service; CI/CD infrastructure spans GitLab, Jenkins, Azure Pipelines, and SonarQube.
Current projects include AKS-based application hosting, legacy monolithic-to-microservices modernization, Azure migration, zero-trust network access, KYC regulatory compliance, and automatic code review infrastructure. Pain points center on legacy modernization, cloud migration, and workflow automation.
