About DeviDevs

We build the AI agents and automations your business runs on, with Claude Code, and we secure them. Based in Bucharest, working with teams across Europe.

Our Mission

Tell us the work that eats your team's week. We build the agent or automation that does it, ship it in about two weeks, fixed-price from EUR 10,000. Claude Code is the engine: it lets us build production-grade software roughly 5x faster, so you get something real, not a demo. We run our own company on a stack of 200+ of these components, so we know what breaks under real load. Then we harden it: prompt injection, access control, and EU AI Act compliance, because an AI system that leaks or ignores the law is a liability, not an asset.

As AI adoption accelerates, the teams that win are the ones who ship agents that actually run in production and hold up under load. We build those, then defend them against prompt injection, data leakage, and adversarial attacks, and keep them compliant with the EU AI Act. Building and securing the same system, by the same team, is what we do.

What We Do

AI Agents and Automation

We build the AI agents and automations your business runs on, with Claude Code as the engine. Production agent stacks, integrations into your tools, handover with docs and a roadmap. EU AI Act readiness built in.

AI Security

Security audits, prompt injection defense, LLM red teaming, and threat modeling to OWASP AI Top 10. We secure every agent we ship and the AI systems you already run.

Claude Code Workshops

Hands-on workshops, one or three days, where your engineers ship a working agent and leave with a roadmap. The cheapest way to start building with us.

Why We Started

DeviDevs was born from a simple observation: small and medium businesses were being left behind in the automation revolution. Enterprise-grade tools existed, but they required enterprise budgets and teams.

Meanwhile, AI was becoming critical infrastructure, but security expertise was scarce and expensive. We founded DeviDevs to bridge this gap.

As a focused consultancy, we offer personalized service, rapid iteration, and direct access to the experts building your systems. We believe powerful automation and robust AI security shouldn't be exclusive to Fortune 500 companies.
