How To Sell AI Agents And Assistants

AI agents and assistants are the most valuable things you can sell, because they

do the most work. An assistant holds a conversation and works with the user

step by step; an agent runs autonomously and hands back a finished result.

If you have built one that genuinely works, here is how to turn it into a

listing buyers will pay a premium for.

Agents vs assistants — sell the right thing

An assistant works with the buyer: multi-turn, conversational, great for

coaching, support, and writing partners.

An agent works for the buyer: you give it a goal and it runs the steps

on its own — research, outreach, data jobs.

Both are premium listings. If you are deciding which you have built, the

[AI building blocks guide](/learn/ai-building-blocks) draws the line, and the

[AI agent marketplace](/marketplace/agents) shows live examples.

Step 1 — Build something that reliably works

A buyer is paying you to skip the hard part: getting the thing to work

consistently. Before you list, make sure your agent or assistant handles the

common cases and the messy ones without going off the rails. Reliability is

the product.

Step 2 — Document the runbook

The biggest difference between an agent that sells and one that does not is

transparency. Buyers want to see exactly what it does before they trust it:

The steps it runs and the tools it calls.
The model you tested it on.
The token cost per run, so there are no billing surprises.

A clear, tested runbook is what turns "interesting demo" into "I'll buy it."

Step 3 — Test it on real inputs

Run your agent or assistant against realistic inputs, not just your happy-path

example. Note where it does well and where it needs guardrails. Buyers reward

listings that are honest about scope — it sets expectations and earns reviews.

Step 4 — Price and publish on Sigrix

Agents and assistants command higher prices than prompts because they do more

work. Price for the value of the job done, publish on Sigrix, and let the

platform handle discovery, checkout, and payouts. Buyers get an editable copy

they own and can adapt.

Tips that make agents sell

Lead with the job done, not the tech. "Tailors your resume to any job

post" beats "multi-step LLM pipeline."

Show the runbook. Visible steps build the trust that closes the sale.
State the model and token cost up front.
Start with reviews in mind — deliver well early, and proof will let you

raise prices.

[Start here](/sell).

How much can I charge for an AI agent?

More than a prompt — agents do multi-step work, so they are priced for the value

of the whole job. Price for the outcome, and let early reviews support higher

prices over time.

What is the difference between selling an agent and an assistant?

An assistant is a multi-turn chat helper that works with the buyer; an agent

runs autonomously and returns a finished result. Both are premium listings; you

sell the one you have actually built.

Do buyers get to edit what they buy?

Yes. On Sigrix a buyer owns an editable copy of the agent or assistant, so they

can adapt the goal, steps, and guardrails to their own workflow.
