On Device Opens Direct API Access to Brand Lift Measurement Data
The Development
On Device launched its Brand Lift Data API on October 6, 2026, giving clients direct programmatic access to its brand lift measurement datasets. The API connects advertising exposure data to verified brand outcome metrics — awareness, consideration, preference — without requiring clients to retrieve results through On Device's own reporting interface. The move positions On Device as a data infrastructure provider rather than purely a measurement vendor, enabling brand lift signals to be ingested into clients' own analytics stacks, media mix models, and activation platforms. The launch is framed explicitly around the 'outcomes era,' signalling a deliberate repositioning as measurement budgets shift toward performance accountability even for brand-level metrics.
Our Take
The structural problem with brand lift measurement has never been the methodology — it has been the custody of the data. When the measurement vendor controls the interface, the data stays siloed, arrives late, and gets summarised rather than interrogated. On Device's API move breaks that custody model. Brand lift data can now feed media mix models in near real-time, sit alongside performance signals in a data warehouse, or trigger optimisation rules mid-flight. That is a material change in how brand investment can be managed. The timing is deliberate: as AI-driven media buying accelerates, the demand for brand signals that can actually inform automated decisions — not just validate them retrospectively — is growing fast. Vendors who can supply that signal programmatically will take share from those who cannot.
What Changed
Marketers can now pull verified brand lift signals directly into their own data environments via API, making brand perception metrics a live, portable input for modelling and optimisation rather than a periodic report reviewed after campaigns close.
Marketing Impact
Marketing science and data teams gain the ability to incorporate brand lift signals into predictive models and attribution frameworks without manual data exports. Media teams can use the feed to inform in-flight budget allocation decisions rather than treating brand lift as a post-campaign diagnostic.
Competitive Implication
Measurement vendors still operating report-based delivery face disintermediation as API-accessible brand data becomes the expectation. In-house analytics teams with existing data infrastructure gain disproportionate benefit; agencies without warehouse capability will struggle to exploit the access.
Strategic Outlook
Expect competing brand lift vendors to accelerate API roadmaps in Q1 2027 as client RFPs begin requiring programmatic data access as a baseline requirement. On Device has set a new interoperability standard that will compress the window for incumbents to respond.
The Exploit
Action Item
Data and marketing science leads running media mix models should contact On Device now to integrate the Brand Lift Data API before Q4 2026 campaigns close — capturing live brand signal alongside performance data for the first clean MMM run of the period.
