Purl Applications Limited provides two software platforms to the out-of-home (OOH) market that helps both buyers and sellers share and understand their inventory, audiences and guaranteed deals.
Our productsdooh.direct facilitates the exploration of OOH inventory and audiences by creatively building ‘Plots’ of inventory, maps, tables and audience data/visualisations that enables discovery of the right frames that reach the right audiences at the right times to satisfy an OOH media brief.
A ‘Plan’ is a workspace that allows the user to select certain inventory from their ‘Plot’ exploration and assemble a targeted campaign plan based on nationwide Media Owner inventory and live availability. This plan can be shared as an interactive proposal to any third party for trading or information purposes.
dooh.direct is supplied with a basic trading facility for API deal-based availability checking and ordering with Media Owners supporting OpenDirect guaranteed programmatic trading . All orders can then be matched against posting and playout logs provided by our media owner partners.
Purl facilitates the exploration of OOH inventory and audiences by creatively building ‘Plots’ of inventory, maps, tables and audience data/visualisations that enables discovery of the right frames that reach the right audiences at the right times to satisfy an OOH media brief.
A ‘Plan’ is a workspace that allows the user to select certain inventory from their ‘Plot’ sandbox and assemble a targeted campaign plan based on live OOH pricing and availability directly from Media Owner inventory systems.
Once a ‘Plan’ is finalised, ‘Orders’ are generated for each of the targeted media owners. Thanks to a direct API connection with the media owner trading systems, the required OOH inventory can be checked for availability and then optioned and/or booked instantly for guaranteed delivery.
A user can load creative into this workspace to be approved by Media owners that is then linked to draft/optioned/booked Purl campaigns for immediate and dynamic allocation to Media Owner CMS systems and inventory.
The direct delivery of Media Owner ‘proof-of-play logs’ directly into Purl enables the complete audit of the campaign requirements, bookings and ads served being achieved in a single system. The fulfilment of a campaign is then enriched with audience data, visualised, monitored and reported in a single dashboard that can be shared with client, trading and operational partners.
Agencies and Media Owners that currently partner with our platforms include:
