We build products, not projects.
We're a team of engineers, designers and strategists who treat code as a tool for change. We build software that is fast, elegant and deeply practical — all at once.
AI at the core
We don't bolt models on at the end — we design systems where LLMs are first-class citizens of the architecture.
Velocity without compromise
Short iterations, deploy automation and observability from day zero. We ship to production many times a day.
Full stack ownership
From interface, through API and cloud infrastructure, to the data model — we take responsibility for the entire chain.
Compliance & security
KSeF, GDPR, social security, e-invoicing — we work with Polish regulations and know them inside out. It's the difference between a prototype and a production system.
Software you can actually watch work.

What we build.
Every Codentra product is the answer to a concrete business problem. We build them with the same philosophy — AI at the core, exceptional ergonomics, full compliance with Polish law.

Modern stack
without compromise.
We pick technologies that won't let us down in two years. We invest in tooling that gives us an edge in speed and quality.
AI Engineering
LLM agents, RAG, function calling, fine-tuning, evaluations. We embed AI where it genuinely creates an edge.
Full-stack development
Frontend, backend, databases, queues, integrations. One team from the first line of code to production.
Cloud & DevOps
CI/CD, infrastructure as code, monitoring, SLOs. Production-grade stability from the very first deploy.
Product design
UX, motion, design systems. The kind of interface you want to stay in longer than you need to.
From idea to production.
Four clear stages, one point of contact, transparent progress.
Discovery
We understand the business, its users and constraints. We define a measurable product goal — before writing a single line of code.
Prototype
In 2–3 weeks we deliver a working version of the product's core. Real, clickable, tested with users.
Build
Iterative development of the full feature set. Daily deploys, continuous testing, transparent progress.
Ship & scale
Production launch, monitoring, optimization of AI and infrastructure costs. We stay with you long term.

Discover ContivoFrequently asked questions about working with Codentra
What does Codentra do?
Codentra is an AI software house based in Świdnica, Poland. We design and build custom software — web applications, SaaS platforms and internal tools — and implement AI-based solutions in businesses. We are the makers of Contivo, an AI accounting system for accounting firms.
What is Contivo?
Contivo is Codentra's own product — the first AI-native Polish accounting system for accounting firms, available at contivo.pl. AI reads and posts documents, and the system handles KSeF, JPK, ZUS DRA, HR and payroll and fixed assets in one cloud platform.
Do you only work with companies in Poland?
Our headquarters is in Świdnica, Poland, and we work with companies across the country. Most of our collaboration happens remotely, so location is rarely a constraint.
How long does it take to build custom software?
It depends on scope. We work iteratively: after discovery we deliver a working prototype of the product core within 2–3 weeks, then build out full functionality in short cycles with frequent releases.
What does an AI implementation look like?
We start by identifying processes where AI will have a measurable impact — such as document handling, answering customer questions or searching company knowledge. Then we build a prototype, measure answer quality and integrate the solution with your systems.
Is company data safe during an AI implementation?
Yes. We design GDPR-compliant solutions with control over where data is processed. We know Polish regulations — KSeF, JPK, ZUS — because we work with them every day in Contivo.
Which technologies do you use?
A modern web stack (including TypeScript, React and Next.js), cloud infrastructure with CI/CD, and large language models (LLMs) with techniques such as RAG, function calling and AI agents.
