Our story
12 years of partenrship¶
We are Stelios Sotiriadis and Dimitris Kargatzis and we first crossed paths in 2013 at the Technical University of Crete. Stelios was a postdoctoral researcher; Dimitris, an ambitious undergraduate in computer engineering. Their shared passion for solving complex systems problems sparked a partnership that’s lasted over a decade.
In 2018, Dimitris joined Stelios again—this time at Birkbeck, University of London—to pursue a PhD under his supervision. But their collaboration quickly moved beyond academia. By 2019, they had co-founded a small consultancy helping London tech companies build and optimize internal DevOps processes.
Stelios led strategy, delivery, and architecture—drawing on his experience managing large-scale R&D projects at IBM, Huawei, and Autodesk. Dimitris led engineering—building infrastructure, automating CI/CD, and deploying resilient cloud-native systems. Within a year, their company was generating real revenue by helping engineering teams automate DevOps workflows and scale operations.
Share vision¶
We shared a simple, powerful goal:
By 2022, we were embedded in fast-moving engineering orgs across sectors. The issue wasn’t bad code—it was broken process. Teams were duct-taping scripts, manually stitching logs, and running post-mortems for incidents that could’ve been prevented.
In 2024, after interviewing 50+ development teams, one insight became clear:
There was no tool to govern the DevOps process the way observability tools govern production.
We built Warestack¶
A tool that doesn’t just track what changed—but how, why, and under what conditions it changed.
Warestack monitors the developer journey:
- Who made the change
- What rules were followed—or bypassed
- What downstream impact it caused
Today, we’re scaling that vision—transforming how teams govern DevOps at scale.
Because the best deployment isn’t just one that works, it’s one where everyone knows what happened, how it happened, and why it was allowed.
