How long does it take to have a first working AI agent in a company?

A demo takes a few days. An agent that works every day on company data takes a few weeks, almost all of them spent on the difficult cases.

In summary
  • A first agent on a single task usually takes 2-4 weeks: the time for a first working version on the company’s data.
  • An agent in production, connected to the systems and tested by its users, takes 4-8 weeks.
  • Timelines stretch for three reasons: late access to data, ERP systems without an API, decisions left open.
  • These are the timelines Yempik gives for its own projects; a system spanning several departments is delivered in phases.

Week by week

This is how a first single-task agent usually goes.

  • Week 1: choose the task, collect real examples, decide what the agent does alone and what goes through a person.
  • Weeks 2 and 3: first version on company data, tested by the people who do that work.
  • Week 4: fixes on difficult cases, then the decision: go to production, change course or stop.

For production you add final integrations, tests on failed requests, monitoring and initial support.

What slows it down

Rarely the technology. Access to data slows it, when it takes two weeks of email with IT or the ERP vendor; so do process questions nobody answers and scope that grows halfway. The fix is simple to state: a contact with time, access ready on day one, one task.

How to tell it is ready

Before starting, pick one number, such as hours spent on the task, customer response time or errors, and measure it before and after. The agent is ready when it beats today on that number and the people reviewing its drafts trust them.

More questions

Can it be done faster?

A demo, yes, in a few days. An agent doing real work needs tests on the difficult cases, and those take a few weeks of real work.

How much does it cost?

With Yempik the first version starts at €8,000 and the production version at €12,000. Price depends on the number of tasks, the integrations and volume and security requirements.
