Pyrobid lets a website or newsletter sell its own ad space under its own brand. Each publisher gets a self-serve advertise page in their name and colours, on a Pyrobid subdomain or their own domain with Pro. Businesses register there, pick a slot or a newsletter send, pay and upload their ad, and it waits for the owner's approval before it runs.
Owners set the price of each slot and keep everything advertisers pay on Starter and Pro, because Pyrobid is a flat monthly subscription with no commission. Payment works the way the owner already gets paid: vouchers turn a bank transfer, PayPal or an invoice into ad credit, and cards run through the owner's own Stripe if they connect it.
Existing AdSense or other ad code keeps filling anything unsold. Banner, sticky, interstitial, native and newsletter formats, targeting, frequency caps, viewable-impression billing and live reports are built in. One tag on any site, or the free WordPress plugin. $29.99 a month after a 14-day free trial.
