Greitas Kodas — Lithuanian for “fast code”

We engineer software. Agents included.

Greitas Kodas is a senior engineering studio. We design, build, and secure software of every kind — including the kind that works on its own: production AI agents and agentic systems — for companies across the EU & US. Since 2015.

02 Services

Six processes.
One senior team.

The flagship is the newest process in the table. The other five have been running — and paying their way — since 2015.

01

Flagship

AI Agent Development

Production agents that plan, act, and deliver — built on Claude and modern LLM stacks, wired into your tools via MCP, evaluated and monitored like real software. Not demos: systems with owners, logs, and rollback plans.
02
Agentic Process Automation
Manual workflows become supervised agent pipelines — with humans exactly where they matter, and nowhere they don't.
03
Custom Software Development
Whole products, platforms, APIs, and pipelines — built fast, built right, and maintained like we still own them.
04
AI & Software Consulting
Architecture reviews, hard build-vs-buy calls, and pragmatic AI strategy — from engineers who still ship.
05
Legacy System Modernization
We untangle aging systems: clean APIs, safe integration surfaces, lower run costs — ready for whatever you plug in next, agents included.
06
Cybersecurity & AI Security
Classic hardening plus LLM-specific threat models: prompt injection, data exfiltration, agent permission boundaries.
07Slot reserved for whatever you're about to bring us.

03 About

A studio named after its own deadline.

Greitas Kodas means “fast code” in Lithuanian — a name that doubles as a service-level agreement. We are a small team of senior engineers only, shipping production software for EU & US companies since 2015 — much of it for security and developer-tooling teams who read the code before they pay for it.

Some of the fastest code now runs itself — under supervision. We build agentic systems the way we build everything else: production standards, no black boxes, and accountability for whatever ships under our name — written by us or run by our agents.

Since 2015

Humans + agents

Values

01
Ship, then iterate
Working software in weeks, then relentless iteration in production. Motion beats meetings.
02
Own the outcome
We're accountable for results, not billable hours — and that includes what our agents do.
03
No black boxes
Everything we hand over is documented, observable, and yours to inspect down to the last prompt.
04
Fast by default
It's in the name. Lean code, lean process, quick answers — speed is a habit, not a sprint.
