What does an AI agent development company do?

It designs and builds software that carries out a defined piece of work across your systems, such as matching transactions or drafting replies, and hands a person the exceptions. The engineering is mostly in the access, the checks and the audit trail around the model.

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

It depends on the workflow and the systems involved. A few firms on this list publish starting prices on their own sites; most, including New Odyssey, quote after scoping one process.

How to choose

Give the agent a defined job. A firm should be able to say what the agent does, which systems it touches and when it hands over to a person.
Ask what it is built on. An agent on a low-code platform is quicker to start; one built into your own systems is easier to control and audit.
Ask to see the audit trail for one decision, and where a person approves.
Test on your own cases, not a demo. Agree the measure before the build starts.
Ask who runs it afterwards and what that costs.

Where New Odyssey fits

New Odyssey builds agents for back-office operations work: a defined job, scoped access to the systems you already run, approval points and a log of every action. For common workflows we have packaged Pegasus agents; for a workflow of your own we build a custom agent. We are not the right choice for a consumer chatbot or a voice agent, which several firms above specialize in.
