The marketplaces that need you, and who decides.
Oxpium builds the list of marketplaces that fit your offer, finds who decides, tells you when one of them is hiring or opening a category, and runs the campaign.

Real marketplaces, not directories.
A marketplace has third-party sellers, a page to recruit them and a commission. A comparison site or a directory doesn't. Tell the agent the vertical, the size, the model: it searches professional databases, public sources and websites, and only keeps the platforms that sell for others.

78 B2B marketplaces with third-party sellers.
Third-party sellers
The agent reads every website, looks for a “sell with us” page and “sold by” mentions, and leaves out directories and comparison sites.
A vertical
Industrial B2B, construction, resale, home, auto parts, fresh food: the agent sorts by what each platform actually sells.
A real size
The seller count shown on the website and the headcount from professional databases, to tell a young startup from an established player.
Retailers going marketplace
Online stores that open their catalog to third-party sellers: the agent spots them by their product pages and their seller page.
The person who runs the sellers, and the terms on display.
At a marketplace, who owns the budget depends on the topic: the founder for a platform decision, the seller team for recruiting sellers, the category manager for getting listed. The agent looks for the right person, reads the seller terms published on the website and verifies every email before adding it.

The founder
At a platform under 50 people, the founder still signs the big decisions: the agent finds them, with a verified email and their cell phone.
The seller side
Head of seller acquisition, seller account manager or category manager: the agent looks for the title that matches what you sell.
The website contact
The partnerships or seller support address published on the website takes over when no decision maker comes up in the databases.
The seller terms
Commission, monthly fee, seller count, countries open: the agent reads each platform's seller page and files every answer in a column.
Automations that tell you which platform is speeding up.
A marketplace hiring two seller account managers or opening a category, or a retailer opening its catalog to third-party sellers: that's when needs change. Each automation reruns its search on schedule and adds what just changed to the top of the list.

2 marketplaces are growing their seller team this week.
The seller team is hiring
Every Monday, an automation flags the platforms hiring in seller acquisition, seller onboarding or category management.
A retailer opens up
Every week, large retailers' websites are reread: the ones that add a seller page or “sold by” mentions move to the top of the list.
Headcount going up
On the 1st of the month, the platforms whose headcount grew by 10% or more since last month move to the top, marked with a badge.
Your own watch
Every Friday, the websites are reread for a new category open to sellers, or for any other watch you can write in one sentence.
A campaign that talks sellers, commissions and catalog.
Marketplace teams hear from sellers all day long. What gets through is a message that starts from their platform: an open role on the seller side, a category just launched, the terms they publish. Email from your mailbox, calls from your browser, stops on the first reply.
Subject Your sellers sellers
Each variable is a column of your list, filled in by the agent.
January or September
Tuesday to Thursday, 9 to 11:30 am, and ideally in January or September: that's when platforms set their roadmap for the year.
One signal per message
Every email comes from the list's columns: open role, new category, published commission. The agent rereads the site before each follow-up.
Calls from the browser
You call from the browser, on a mobile number. Every call is recorded, transcribed and then summarized back in the list.
Stops on reply
As soon as a platform replies, the campaign stops for them. You take the conversation from there, and the next follow-up never goes out.
Frequently asked questions
Write “B2B marketplaces in the US for industrial supplies and construction”. The agent searches professional databases and public sources, reads each website to keep only the ones with third-party sellers, and hands you the list with the city, the vertical, the seller count on display, the headcount and the website.
Ask “find the head of seller acquisition or seller partnerships at each marketplace, with their email”. The agent looks them up by title and company and verifies each email. At the smallest platforms the role doesn't exist yet: the founder recruits the sellers.
Tell the agent once: “every Wednesday, reread the websites of the retailers on my list and flag the ones that add a seller page or products sold by a third party”. The ones that just opened up land at the top of your list, with what changed on their site.
A first email built from the open role, then an agent step that reads the platform's categories, finds the ones short on sellers and writes the follow-up about them, and a call to close. Emails go out from your own mailbox, and the sequence stops as soon as a platform replies.
For 150 platforms with their website and seller page read, 120 verified emails and 50 cell phones, count around €25 of data on top of the subscription. An agency typically charges a few hundred euros for a comparable list, delivered once and never updated.See pricing
By the website. The agent looks for a page to become a seller, product pages “sold by” a third party and seller storefronts. A comparison site, a directory or a store that only sells its own stock drops off the list, unless you're precisely after the retailers about to open up.
