About Vstorm

Agentic AI for companies that grow by getting stronger.

We call them Small Giants: companies that compete on focus. Vstorm builds the agentic AI layer that lets a focused team operate like one many times its size, in code built for daily use and owned by you.

Mission

We engineer agentic AI that companies own and run themselves, built on open standards we help write.

We have been building AI since 2017.

The destination 01

Small Giants

A company that grows by making its people capable of more. With the right technology, a focused team outperforms organizations five or ten times its size and keeps the speed and identity that made it worth building.

The vehicle 02

AgenticOS

One layer where every agent shares context and builds on what the others know. Buying agents one at a time gives you a chatbot here and an automation there, each solving a small problem, none of them compounding. AgenticOS is the operating layer instead: decisions get faster and knowledge stops living in people's heads.

The road 03

How we work

We map how the company actually runs, redesign one high-impact process around agents, build it with the team and train the people who will run it. A Proof of Value comes before the full build. Software nobody adopts is expensive shelfware.

Antoni Kozelski, CEO and Co-founder of Vstorm
From the CEO

“We help write the open standards that agentic AI runs on. In the Agentic AI Foundation we take part in the working groups on observability and traceability, and our engineers contribute to Pydantic AI, LangChain and LlamaIndex. Then we put those standards to work inside companies, in systems each company owns and runs itself.”

Our journey

Our road to the frontier of agentic AI engineering.

Since 2017 we have engineered AI systems that our clients own: language models before they had a name, agent harnesses from the first usable LLMs, and agentic AI today.

  1. Founded

    NLP and machine learning, before LLMs

    Vstorm starts with natural language processing, data engineering and machine learning, building systems companies use every day.

  2. Agentic harness engineering

    From NLP and ML to agentic harnesses

    With GPT-3.5's launch in November of that year, we start engineering the harness around the model: the tools, context and checks that let it do real work for a client.

  3. Recognition

    Deloitte Technology Fast 50 Central Europe

    Vstorm enters the Deloitte Technology Fast 50 Central Europe, the ranking of the region's fastest-growing technology companies. Agentic AI engineering was the driver of our success.

  4. Track record

    In production before the frameworks were stable

    Our first agentic systems went live in production in July 2025, handling more than 100,000 queries a month. That was before the frontier agentic frameworks released their 1.0 versions: Pydantic AI 1.0 on September 4, 2025 and LangChain 1.0 on October 22, 2025.

    2025.
  5. Standards

    The first agentic AI engineering company to shape open standards

    In December 2025, days after its launch, Vstorm became the first agentic AI engineering and services company to join the Agentic AI Foundation. OpenAI, Anthropic and Block co-founded the Foundation under the Linux Foundation as a neutral home for open agentic standards such as the Model Context Protocol (MCP) and AGENTS.md, to name a few. The Foundation builds open standards for agentic AI with input from practitioners who run these systems in production, and Vstorm contributes from its live implementations.

    2025.
  6. Open source

    Built in production, shared as open source

    Every production system we build teaches us something. Many of those lessons solve problems other engineering teams face too, so we publish them as open source: 30+ public repositories, 4,000+ GitHub stars, more than 10M PyPI downloads and 1.8 million downloads a month. The success of our open source rests on its reliability and on the developers who use it.

  7. Upstream

    Our open source in a frontier agentic framework

    In July 2026, a frontier agentic framework merges technology from four of our open-source libraries into its official framework. Teams that build on it now use capabilities that started in our client work.

  9. Award

    We received the Open Agentic AI Innovation Award

    On 23 October 2026, Vstorm received the Open Agentic AI Innovation Award at the Agentic AI Foundation's first Annual Technical Excellence Awards, presented at AGNTCon + MCPCon North America in San Jose. The award recognises organisations that deployed or advanced AAIF's open standards in production, research or public tooling with real-world impact.

  10. Agentic AI at scale

    50+ workflows agentified

    More than 50 complex, multi-step workflows run in production for our clients worldwide, with agents we have built handling millions of queries since launch. We work with leading companies to change how their operations and business models run.

    Now.
    The Vstorm core team

Path forward.

We will keep contributing to the open standards of agentic AI and to the frontier harness frameworks. Working on them from the inside is how we understand the technology, share what we learn with the community and help shape where agentic AI goes next.

Then we bring those standards and practices to our clients, so the new ideas reach their business and change how it runs.

What we value

Our values.

01

Ownership.

You know what your role needs and do it before anyone asks.

  1. If you can make a decision that unblocks the work, you make it.
  2. You finish what you start, flag delays early, own your mistakes and bring a fix.
  3. Before time off, you hand over.
02

Excellence.

When there is room, you go past the standard.

  1. On something new, you say "I don't know, but I'll find out" and test it yourself.
  2. You tell clients plainly what will not work and turn feedback into growth goals.
  3. Engineers learn the business; everyone else learns AI for their role.
03

Collaboration.

Different roles, one goal.

  1. You consult others and share what you know.
  2. Hard things get said directly and with care.
  3. If a doc or async thread will do, we skip the meeting; when we meet, there is an agenda and notes.
  4. Engineers have reserved time to work with other teams.

We are hiring. Engineers and operators building agents that clients run every day.
