Kostecki Labs

AI from silicon to model

On your infrastructure, not in someone else's cloud.

We design neural networks, fine-tune LLMs, build chatbots, virtual assistants and dedicated AI systems — on your own hardware too, for companies that can't or don't want to keep their data in someone else's cloud.

You're talking to an AI assistant. The conversation stays with us — it doesn't go to any other third-party AI.

What we do

From low-level neural networks to running LLMs

We build AI, not just use it. That's why we pick solutions for your problem, not for whatever happens to be trendy.

Dedicated AI models

We design and train models from scratch — for specific use cases where off-the-shelf solutions fall short. Classification, prediction, computer vision, NLP. For your data and your problems.

For: manufacturing, insurance and medical companies, research institutions.

Fine-tuning large language models

We adapt LLMs to your domain and data — legal, medical, financial, technical. A model that understands your terminology, your clients, your documentation. Runs at your place, not at the vendor's.

For: companies with proprietary documentation and specialised domains where generic LLMs are too shallow.

Hardware for private hosting

We spec, configure and deploy infrastructure to host models at the client's site. From single GPU servers to clusters. Inference, fine-tuning, RAG — all on your hardware.

For: IT in regulated companies, security departments, organisations where public cloud is a non-starter.

Embedded AI and edge computing

Neural networks on microcontrollers. Autonomous control systems. Inference on resource-constrained devices. Our background: aviation, UAVs, lunar missions.

For: robotics, defense, aerospace, IoT, industrial automation.

Who we work with

Who we work with

We work with companies that have sensitive data, non-standard needs, or regulatory requirements that rule out public cloud.

  • Regulated industries

    Finance, law, healthcare, insurance. Where professional secrecy, GDPR and sector regulations demand keeping data under your own control.

  • Industry and manufacturing

    Automation, quality control, predictive maintenance, production-line data analysis. AI that runs on the factory floor, not in the cloud.

  • Defense, aerospace, dual-use

    Embedded AI for autonomous systems, UAVs, sensors. Operational and legal requirements that rule out external infrastructure.

  • Companies with sensitive IP

    Design offices, R&D, research. Your know-how shouldn't be training someone else's model.

Product

Cognis

Secure on-prem AI system for your company.

The full power of large language models in the closed environment of your server room. Your documents, correspondence and company knowledge never leave your internal network — not to the American giants, not to any cloud.

How we work

How we work

Five steps from the first email to a working solution.

  1. 01

    Discovery call

    20–30 minutes. We understand your problem and advise whether AI makes sense at all. Free, no strings attached.

  2. 02

    Scope and quote

    A concrete scope of work, a concrete quote, a concrete timeline. No "it depends" and no hidden costs.

  3. 03

    Prototype / proof of concept

    We start from the smallest working solution. We validate assumptions before we invest in a full rollout.

  4. 04

    Production deployment

    On the target infrastructure, with full technical and operational documentation.

  5. 05

    Support and development

    Long-term collaboration, ongoing support, or handing everything over to your team. The choice is yours.
