Lumen, also known as Lumen Research, a privately owned company headquartered in the UK, was founded in 2013 and employs approximately 60 individuals. The company operates as an attention technology firm that utilizes eye tracking methodologies to optimize media buying strategies and creative development.
On June 30, 2026, SeenThis launched SeenThis Attention, a new video advertising product independently measured by Lumen Research. The offering allows agencies and advertisers to purchase against verified attentive outcomes using attentive CPM (aCPM) and Cost Per Attentive Second (CPAS) buying models. Previously, on May 26, Lumen Research reported that Trainline advertising delivered double the attention of standard mobile display. This finding stemmed from a partnership where Lumen measured advertising performance on the Trainline app against broader media benchmarks, indicating Trainline's high-attention, high-impact environment. Earlier in May, Teads expanded its partnership with Lumen Research to integrate attention measurement capabilities across its connected TV (CTV) offering. This extension, which included an announcement on May 12, provides Teads with exclusive access to Lumen's CTV attention measurement for HomeScreen placements across the US, EMEA, APAC, and Latin America, building on their existing collaboration in digital environments.
