No rate card chase, no email chain. Search by audience, book at the owner’s price, upload once. Setup takes minutes, not weeks.
Type the audience, not the address. Halo finds where those people actually are, hour by hour.
Every listed site ranked by audience match, with the owner’s price shown up front.
Many owners, one insertion order, one invoice. Upload your creative once and we check it fits every format.
Proof of play lands on the booking, and the people who saw it can be reached again online.
Halo is the audience engine inside Winboard. It tells you who was actually in front of a space, what else they do, and whether you can reach them again. It reads anonymised, opted-in device movement around any geofenced place at a global level, matches it to census, spend and vehicle data, and profiles every listed space by daypart. Retargeting through Halo then takes the people who were there and reaches them again across Meta, TikTok, Google, YouTube, Pinterest and programmatic display, reported against the same booking.
See what a Halo report looks like. An anonymised sample location insights report for a real site: catchment, dwell, audience profile by daypart and the retargeting audience it produced. No personal data, no sign-up.
View Sample ReportWe remove barriers, middlemen and manual admin, letting brands focus on creativity and owners focus on opportunity. We own no screens and no sites: owners set the rate, approve every campaign and keep the relationship.

Halo already profiles every listed site by daypart. For owners that becomes something to sell on top of the space: an audience profile on every rate card, a location insights report under your brand, and a royalty each time the audience from your sites is bought for retargeting. Paid three ways on the same inventory.
How it works for owners →Winboard runs on the infrastructure you already trust.
Any business or brand that wants to get in front of a specific audience in the real world, and any owner of a space that audience passes through. Agencies use it to buy the long tail on one order; owners use it to sell space and audience data.
Whatever the owner has set. Every listing shows its rate before you enquire, and the live rate guide shows typical pricing by format and city. There is no platform fee for the buyer.
No. Winboard owns no inventory. Asset owners list their own sites, set their own rates and approve every campaign. Your existing deals are untouched.
Create an asset owner account, add the site with its specs and rate, and approve bookings as they arrive. No listing fee, no exclusivity, pause any time. Start here
The whole market in one search. The audience in the plan from day one. The admin off your desk.
