Custom AI agent development

Custom AI agent development on your own stack.

Some agents cannot run on a managed platform. The data may have to stay in your cloud account, or the job may need your internal database and APIs. We build those agents on your infrastructure. You get a written design before the build starts, one fixed price, and the code in your repository.

01In practice

What a custom build gives you

Custom work is for jobs that managed hosting cannot take on. The agent is ready for your security review, and your engineers can take it over after handover.

Runs in your cloud

It runs in your cloud account and region, behind your network rules, ready for a security review.

Connects to internal systems

It works with your database, internal APIs and older systems that have no ready-made connector.

Tested and monitored

Each build ships with tests, evaluations on real cases, monitoring and alerts, so you find out when a change breaks something.

You own it

The source code, documentation, infrastructure and accounts are in your name, and you pay us no licence fees.

02What's included

What a custom build includes

Every custom build goes through these stages, and each one is scoped and priced in writing before work starts.
Discovery and written design
We agree the architecture, data flow, risks and what the agent may do on its own in writing before building anything.
The build
Python or TypeScript, with LangGraph, CrewAI, n8n, Make or vendor tools you already pay for. We choose the model for each step by cost and quality.
Integrations
Your APIs, database, webhooks and internal tools, with least-privilege keys and secrets kept in your vault.
Evaluation and guardrails
A test set of real cases run before every release, approval queues for risky actions, spend limits and an audit log.
Deployment
On AWS, Google Cloud, Azure or your own servers, with CI, monitoring and alerts set up.
Handover
The repository, documentation and runbook, and a working session with your engineers.

03How it runs

How a custom build runs

Scope and price arrive in writing within 2 business days of your brief. We start building after you sign off the design.
  1. 01Day 0

    A 30 minute call

    We discuss the job, the systems involved and your security and data constraints, with the engineer who would build it. The call is free.
  2. 02Within 2 business days

    Written, fixed-price quote

    The quote sets out scope, milestones, timeline and price. Larger builds are split into milestones you approve one at a time.
  3. 03Build

    Milestones and demos

    Each week you see working software running on your data, with evaluation results you can read and approve.
  4. 04Launch

    Deploy and hand over

    The agent goes live in your environment with monitoring, docs and a runbook. Maintenance is optional.

04Fit

Who it's for

Where a different service fits better, we link to it.

A good fit if

  • Data must stay in your own cloud account or region
  • The job spans internal systems with no ready-made connector
  • The agent has to pass a security or compliance review
  • You want your own engineers to own the code later

Not a fit if

  • The job is a standard workflow that would run on Qoren, which is faster and cheaper. See done-for-you agents
  • You want a prototype with no plan to run it in production.
  • You are not yet sure which workflow to start with. Start with consulting

05Price

A fixed price, quoted after a call

The price depends on your systems and rules, so we set it after the call. You get one fixed figure in a written quote within 2 business days. We do not bill by the hour.

06FAQ

Questions

How much does it cost to build a custom AI agent?

It depends on the systems it touches, the guardrails it needs and where it runs. We give one fixed price after a call, in writing within 2 business days. If a standard version of the job would run on Qoren, we tell you, because that starts at $2,000 per workflow.

What does an AI agent development company actually deliver?

Working software in production. From us that means a written design, the agent and its integrations, an evaluation suite, a deployment with monitoring, and the code, documentation and accounts handed over to you.

Which frameworks and models do you build with?

Python or TypeScript, with LangGraph, CrewAI, n8n or Make where they fit, and models from OpenAI, Anthropic, Google or open-weight providers chosen per step for cost and quality. We use what your team can maintain.

Can you deploy on our own infrastructure?

Yes. That is the main reason to choose custom development. We deploy into your AWS, Google Cloud or Azure account, or your own servers, inside your network and region.

Can you work with our engineering team?

Yes. We can build alongside your engineers, follow your code review and deployment process, and hand over in a working session so they can own it.

Who owns the code?

You do, from the first commit. It lives in your repository, runs on your accounts and carries no licence fee to us.

Will you sign an NDA?

Yes. We sign a mutual NDA before you share anything sensitive.
