ITRex review

A staged budget with a go or no go gate: $15,000, $30,000, then $100,000 and up.

Verdict

ITRex prints the most honest budget shape on this list for a serious agent: three stages, each with a range. A two to four week feasibility assessment at $15,000 to $40,000 checks the use case, payback and data readiness. A four to eight week proof of concept at $30,000 to $80,000 tests one high value workflow against your measures. Production, with integrations, guardrails, observability and LLMOps, starts from $100,000. Its own page says agents that act across CRM, ERP and internal systems begin at $100,000 and can pass $500,000.

What customers praise

The go or no go criteria come before the money is spent, and the page is candid that a working agent inside real systems is a six figure job. A US office in Sacramento gives a California counterpart.

What customers criticise

These are ranges, not fixed prices, and the final number is set per project. Production from $100,000 is out of reach for many companies under 100 people. The pages read name no client, and much of the engineering is in Warsaw, so ask where your team sits.

Best for

A US company planning an agent that has to act inside its CRM, ERP and its own systems, which wants a staged budget with a go or no go decision before the expensive part.
