Marline gives agents the tools to run inventory, listings, ads, customers, wholesale, and supply. You approve the calls that matter.
Every channel has its own catalog rules, its own inventory count, its own ad console, and its own inbox. Most founders end up as the glue between them.
The AI tools on offer mostly sit in a chat window and wait to be asked. The work still lands on you.
Two best sellers will run out before the next shipment lands. Reorder, or slow the ads?
A Walmart listing was suppressed overnight for a missing attribute.
A seasonal campaign is still spending two weeks after the season ended.
The TikTok Shop photos for a new product show the wrong color.
A boutique buyer wants a line sheet and net-30 terms by Friday.
A supplier pushed the ship date back nine days.
Each module gives an agent the integrations, written procedures, and limits it needs to own one job. They share one catalog, one inventory count, and one activity log.
One catalog, four storefronts.
Keeps one catalog in sync across every channel. Writes and repairs listings to each channel’s rules, and catches suppressions before they cost a day of sales.

The math is simple. Keeping it current for every SKU on every channel is the work.
An agent earns autonomy one task at a time. It never starts with it.
Marline connects to your storefront, marketplaces, ad accounts, inbox, and inventory. Agents start with read access.
Each agent works from skills: written procedures for one job, like fixing a suppressed listing or planning a reorder. It does the work and stages the change. Nothing goes live yet.
Proposals reach you one at a time, with the reasoning and the numbers behind them. Approve, edit, or reject. Your edits become rules the agent follows next time.
Evals test each agent against real past decisions. When its work passes those tests and your reviews, you can let it act alone on low-risk tasks. You decide when, and you can take it back.

Claude
Pricing, budget shifts, supplier problems, anything ambiguous. Claude weighs the evidence and writes a recommendation with its reasoning.
Commitment
You
Spending money, changing live listings, and anything that reaches a customer or supplier in a new way. A person signs off.
For brands that sell on more than one channel, run with a small team, and want agents doing the operational work without giving up control of money, customers, or live listings.
