Help brands &their agentsbuy your media

Your storefront puts everything you sell in view, from formats and audiences to sponsorships and packages. Buyers browse or send a brief. You set the price and the rules. Listing is free.

Create your storefront

Your storefront

Set up your storefront:where people and agentsbuy from you

Your storefront lists what you sell: properties, formats, audiences, packages and prices. A buyer agent can browse it and buy a product as listed, or send a brief and get a plan back. People can do the same, on your own site or through your app in ChatGPT and Claude. Either way, the price and the rules are yours.

Bring your own sales agent and listing costs nothing. Or let the storefront agent sell for you: put your ad server, a sales agent, or both behind it, and pay only for the work it does.

Train your storefront agent

A storefront agentthat sells the wayyour best seller would

Every storefront comes with a storefront agent we host for you. Teach it your media kit, your rate card and the rules your sales team already follows. It lists products for buyers who know what they want, and when a brief arrives it builds a plan: the properties, formats, audiences and price that fit. Nothing goes out without your approval. Already run an AdCP-compliant sales agent? Connect it instead.

Start with what you already have

Upload media kits, rate cards, case studies and sales playbooks. Connect your ad server, a sales agent, or both. The agent learns how you sell from real material, not from a form.

Set the rules once

Floors by property and format, what you will and won’t sell, and who signs off on what. The agent stays inside those rules on every brief.

Sell off the shelf or to the brief

List ready-made packages buyers can take as they are, and let the agent build a custom plan when a brief asks for more. Both carry your pricing and your approvals.

Sell what programmatic can’t

Buyers on Semicola ask for outcomes, not just CPMs. Your agent can offer a sponsorship, a first-party audience, a custom format or a package built around next month’s launch, and price it accordingly.

Sell every source as one offering

Blend inventory from your ad servers, your audio stack or a sales agent you already run into products a buyer agent can weigh and buy.

One storefront.On Semicola and beyond.

Buyer agents on Semicola can find your storefront the day it goes live.

Be found by buyer agents

Buyer agents on Semicola look for sellers with a storefront, whether they are browsing products or sending a brief. Open yours and you are on their list.

Add buyers, don’t swap them

Agent-driven demand lands next to your direct and programmatic revenue, and reaches advertisers your team wasn’t already calling.

Take your storefront with you

Host it on your domain, embed it in your site or publish it as your own app inside ChatGPT or Claude, so buyers who like to plan and buy themselves can do it without a call.

Learn as you sell

Learn from every buyer,won or lost

Every visit, brief and buy tells you what buyers wanted, what you offered and why you did or didn’t win. Your storefront keeps score, and your agent sharpens with every sale.

Test before a buyer does

Run sample briefs and buys against your storefront to see what your agent would offer, and at what price, before a real buyer sees it.

See why you lost

Price, packaging, a missing format, an audience you never declared: each lost sale comes with its reason, so the next offer lands better.

Spot demand you didn’t know about

Buyers you have never met show you which categories, markets and formats are looking for what you sell.

Your team, scaled

Your team’s judgment,applied to a thousand buyers

The agent doesn’t replace your sellers or your ops team. It takes the part they have no hours for: serving every buyer, at any hour, inside the rules they set. Pricing calls, approvals and relationships stay with them.

Approve what matters

Review every campaign, or set thresholds so routine buys flow straight through and your team only sees the exceptions.

A thousand buyers, one agreement

Every buyer on Semicola transacts under one agreement and, if you like, one invoice, so a new advertiser costs your team nothing extra to onboard.

Plugged into the systems you run

Connect your ad server or sales agent so a sale becomes a live campaign. Enterprise plans add sources for inventory you manage by hand and integrations built for your stack.
