Your visitors are your moat. First-party data is not just post-registration PII but the behaviour and signals that you visitors present on your owned domains. This rich data set of your anonymous and known users has been degraded by the signal loss from third-party cookie restrictions. The way forward is first-party so you can build up that asset of audience data and gain usage again inside your organisation and collectively with partners and publishers to maximise business outcomes. All accurately and securely. 

The building blocks for your organisation:
1. Identity - Deterministically and privately identify 100% of your site visitors, and maintain their identity across all browsers and all of your domains for a rolling 12 months
2. Attribution - lift your data inputs into your attribution efforts. Gain clear and actionable data signals and understand where its effective to place your media investments
3. Data partnerships - connect your total traffic data (known and unknown) with partners for enrichment and / or publishers to segment and advertise to your customers off-network. 
4. Media Optimisation - stream meaningful events from your digital assets to premium publishers, campaigns optimise in real-time, reducing waist and increasing performance all with clear insights into campaign performance to your business KPIs
