SquareDev is an AI and data agency building secure, autonomous AI agents, LLM tooling, and open-source ML monitoring for workflows, document search, and customer support.
SquareDev builds secure, autonomous AI agents and intelligent automation for internal workflows and customer engagement - domains where an agent with tool access, document search, and customer-support reach is effectively an untrusted-input surface. Founded in 2018 and based in Greece with work across Europe and internationally, the agency focuses on making LLM-powered systems safe and robust rather than merely functional: the SquareDev AI platform gives developers frameworks, workflows, and infrastructure for building AI applications on large language models, with an emphasis on controlled behavior and reliability.
The technical stack spans AI agents, LLMs, machine learning, ML monitoring, intelligent automation, data-driven decision making, developer tooling, and system integration. Concrete deliverables include an open-source machine learning monitoring platform and open-source developer tools for building AI applications - monitoring being the part that surfaces model drift and degraded behavior before it reaches production workflows. Verticals covered include internal workflows, document search, content generation, customer engagement, and customer support.
Backed by over €2 million in AI research investment from parent group Quality & Reliability Group, SquareDev runs an active research program tied to European research projects and collaboration with universities and enterprises. The company operates on a hybrid working model and maintains a continuous-growth posture, with open-source contribution treated as part of the day job rather than a side channel.
