Lumen, also known as Lumen Research, is a privately owned company headquartered in the United Kingdom. Founded in 2013, the company employs approximately 60 individuals. It specializes in ad measurement and verification. Functioning as an attention technology company, Lumen utilizes eye tracking to optimise media buying and creative development processes.
On July 27, 2026, InMobi Advertising announced the launch of FRAME Attention, a certified high-attention media product for mobile in-app video and connected TV (CTV), validated by Lumen Research. This product aims to allow advertisers to purchase campaigns based on attention rather than traditional viewability metrics, addressing limitations in digital video buying. Previously, on July 26, 2026, Lumen Research, in partnership with Mail Metro Media and Havas Media Network UK, released a study indicating that digital environments with lower ad loads drive more attention, enhancing brand recall and purchase intent. This followed the initial launch of InMobi Advertising's FRAME Attention on July 24, 2026. Lumen Research validated this offering, which promises a minimum floor of 8000 Attention Per Mille ("APM") and reportedly delivers 3.5 times more attentive seconds than equivalent YouTube video ads, available globally to brand advertisers and agencies.
