How it works

Idea to production. In three steps.

AI does the heavy lifting. Senior engineers make every decision that matters.

Who it’s for

Built for founders and product teams.

Here is where it works best, and where it doesn’t.

Support teams

Agents that resolve tickets end to end, with human approval.

Operations and back office

Invoices, orders and data entry automated.

Knowledge-heavy companies

Answers grounded in your documents and data.

Sales and success

Research, follow-ups and CRM updates on autopilot.

Document workflows

Contracts, forms and reports read and processed.

Product teams

AI features built into your existing app.

Not the right fit

Fully autonomous decisions with no human oversight in regulated areas.
Projects without access to the data or tools the agent needs.
Certified compliance from day one, such as HIPAA or PCI audits.
Open-ended research without a defined first release.

How we work

Six stages, one team.

Pricing

Start free. Ship at a fixed price.

Two steps. The prototype costs nothing, and the release costs exactly what we agree.

FAQ

Questions, answered.

Straight answers about cost, timing, quality and ownership.

How much does it cost to build an AI agent?

The price is fixed for the agreed scope and set before work starts. You first get a free working prototype of the core flow in 1 day, then a fixed price and release date for the production version.

How long does it take to build an AI agent?

A working prototype takes 1 day. The production release date is agreed upfront and depends on the scope; AI speed with senior engineering makes it much faster than classic development.

How do you stop the agent from making mistakes?

With guardrails, evaluation sets, human-in-the-loop approval for risky actions and monitoring in production.

Which models do you use?

Claude, OpenAI or open models, chosen per task for quality, speed and cost.

Is our data safe?

Yes. Data stays in your accounts, access is limited to what the agent needs, and nothing is used to train third-party models.

Is the prototype really free?

Yes, with no commitment. After a 30-minute call we build a working prototype of your core flow in 1 day, and then you decide whether to continue to the release.

Will the price go up during the build?

No. The price is fixed for the agreed scope. Anything new you want to add mid-build is priced separately and built only after you approve it.

Who owns the code?

You do, 100%. The source code, repository and accounts are yours, and the release ships to production under your name.

Is AI-written code safe to ship to production?

It ships only after senior review. Senior engineers own the architecture, security and code quality, and automated tests run on every change.
