A small team should be able to sell everywhere without becoming the glue.
A brand that sells on Shopify, Amazon, TikTok Shop, and Walmart does every job four times: four catalogs, four inventory counts, four ad consoles, four inboxes. Most founders end up holding it all together themselves.
Marline gives that work to agents, and keeps the decisions with the person who owns the store.

The name
Said MAR-lin, like the fish
Marline is thin, tarred twine. Sailors wind it tight around the end of a rope, or around two ropes laid side by side, so they hold together and don’t fray.
A store that sells on four channels pulls apart unless something binds it. The agents do the winding, turn after turn. A person decides what gets bound.
The mark is two cords and three turns. The turns are copper, the color this site saves for your decisions.
How Marline is built
People make the calls that commit.
Money, live listings, and new relationships with customers and suppliers go through a person. Every time, in every module.
Show the work.
Every proposal comes with its numbers and its reasoning. Every action goes in one log a person can read.
Autonomy is earned, and it can be taken back.
An agent starts with read access and no autonomy. It earns the right to act alone one narrow task at a time.
Prove it with examples, not claims.
Until Marline has customers, this site shows the mechanism on example data and says so. No invented numbers.
Sell on more than one channel?
Join the waitlist and we'll write when access opens. Or write to the founder directly.
