AI agent development company

Your processes, redesigned for agents

Agents that take the manual work out of one workflow, tested on your data against a target agreed before the build. The code and decision logic are yours by contract.

Why agent pilots stall

Most agent pilots stall on the process around them.

We redesign the process, prove it on your data, and you decide go or no-go on measured results.

  1. 01

    Where it stallsThe old workflow gets an agent on top.

    What we do We redesign the work first: fixed rules stay in code, agents take the judgment calls, people keep the decisions that matter.

  2. 02

    Where it stallsThe pilot ends with a demo and no decision.

    What we do A Proof of Value on your data ends in go or no-go, with measured accuracy and running costs.

  3. 03

    Where it stallsYour logic ends up locked in a vendor's platform.

    What we do You own the code, data and decision logic by contract, and the model stays swappable.

How we work

A redesigned process your team owns

One team, from the first workshop to a system your people run.

  1. 0103

    Your process, redesigned

    We map the process, cut the steps that only move data, keep fixed rules as code and keep people where judgment matters.

    • Human checkpoints in the redesign
    • Go/no-go Proof of Value
    • Accuracy and running costs measured

    Built from parts we already run

    Agents where the work needs judgment, code where it must be exact. Our engineers contribute to the open standards agents run on, so your system keeps up as they change.

    • Components we already run
    • Integrations, guardrails and evaluation suites
    • Every agent action monitored

    Sovereign by design

    The agent runs in your environment on hosted or open-weight models, and the model stays replaceable.

    • Your code, prompts and evaluations
    • Runbooks and team training
    • No license or platform fee
Engineering in the open

We help build what agentic AI runs on

Open standards, open-source tooling and published research, all public, so you can check our engineering before you hire us.

Shaping agentic AI

The first agentic AI engineering company to join the Agentic AI Foundation

The Linux Foundation formed it around Anthropic's MCP, OpenAI's AGENTS.md and Block's goose. AWS, Google and Microsoft are platinum members. In its own words: “Together, we're shaping the future of agentic AI.”

Open source

We build open-source agent tooling that other engineering teams install

9M+ PyPI downloads
3,900+ GitHub stars
31 public repositories

Framework contributors

When the framework breaks, we fix it at the source

We maintain our own open-source agent framework and contribute fixes to the frameworks our agents run on, through official partnerships with their teams. Breaking changes reach us before they reach your codebase.

Research

Our engineers and PhDs publish peer-reviewed research

Peer-reviewed papers on agent architectures, evaluation and AI security, and an open benchmark anyone can rerun against our results.

Track record

Frontier AI teams now build on what we shipped first

Our client agents were in production before most of today's agent frameworks had a stable release. You get a team that already knows what breaks between a promising demo and a system people rely on every day.

Ways to start

Each path starts with a free call with a founder or senior AI engineer. A build goes ahead only after its Proof of Value meets the agreed threshold.

FAQ

Questions about AI agent development

What do AI agent development services include? +
The full path, from choosing the workflow to handing code and runbooks to your team. In between: the agent architecture, a Proof of Value on your data, the full build with integrations and guardrails, and deployment with monitoring. You can also bring us in for one part of that path, such as an audit of an agent you already run.
Should we build a single agent or a multi-agent system? +
Start with one agent when the workflow is bounded and the data sources are manageable, because it is faster to build and easier to audit. A multi-agent system is worth the extra complexity when the work is too broad for one agent or needs several specialists running in parallel. We make that call in the first phase of the engagement, before any build.
How is a custom AI agent different from RPA or an automation platform? +
RPA and workflow platforms follow fixed rules and break when the input or the process changes. An AI agent chooses the next step or tool based on the situation, so it can work with unstructured documents and handle exceptions. That flexibility needs evaluation, guardrails and monitoring, and we build them in from the start.
How long does AI agent development take? +
The first milestone is a Proof of Value on your own data, so you see whether the agent works before committing to a full build. The timeline for the full build depends on the integrations, the state of your data and your compliance requirements, and we estimate it once the Proof of Value is done.
What does a Proof of Value include, and what does it cost? +
One workflow, a working agent on your real data and edge cases, and an evaluation suite that measures it. Before it starts, your experts and our engineers agree the success threshold. From your side it needs access to the data and systems of that workflow and a named owner. It ends in a go or no-go decision backed by measured accuracy and running costs. Its cost depends on the workflow and the systems it touches, and it keeps your first commitment limited.
How much does AI agent development cost? +
Cost depends on the number of workflows, the systems the agent connects to, and your hosting and compliance requirements. Starting with a Proof of Value keeps the first commitment limited and shows the running costs of the agent before the full build.
Do we own the AI agents you build? +
Yes. The code, the IP and the decision logic are yours by contract. Code, configuration and runbooks move to your infrastructure, and the system keeps running without us. The model is the one you choose, hosted or open-weight, and it can be swapped. Vstorm charges no license or platform fee for the agent itself; model and hosting costs are yours and visible from the Proof of Value onwards.
Can the agent run on our own infrastructure? +
Yes, in infrastructure you control, with a hosted or an open-weight model; we scope that per project. The model is designed as a replaceable component, so changing it does not mean rebuilding the system.
Which frameworks and models do you use? +
We choose per project and write down why: Pydantic AI, LangChain, LangGraph or LlamaIndex for the agent, and a model per task, hosted or open-weight. Our engineers contribute to the open standards and frameworks agents run on, and we publish our agent tooling as open source.
What happens after the agent goes live? +
An agent that works on day one can drift as your data and workflows change. We set up monitoring and feedback cycles at launch, and can keep maintaining models and integrations afterwards, or train your team to do it.
Which companies do you work with? +
Enterprises and technology companies with an agent system to build, in Europe, the United States, the United Kingdom and the Middle East.
