Founders
Hello! We are Dimitris (left) and Stelios (right), the founders of Warestack!
We have been working together for the past 11 years, and in 2024, we founded Warestack!
What is our story?
Warestack’s journey started with a shared passion and a real-world challenge. Dimitris first met Stelios at the Technical University of Crete, where Stelios supervised his undergraduate thesis and introduced him to the fascinating world of distributed systems. Later, Dimitris moved to London to pursue a PhD, with Stelios continuing as his mentor. During this time, they worked closely together and experienced a major pain point: managing code changes across multiple environments was complex and often led to wasted time, confusion, and slowdowns for development teams.
Determined to find a solution, they started building Warestack. Since started Warestack, the mission has been simple: make it easy for teams to follow best practices for code changes. Warestack integrates with popular tools like GitHub, GitLab, and Jira to streamline every little code change of development teams — maintaining quality standards for pull requests, deployment reviews, workflow runs and more.
