LUMO partners with SunSeekr to bring real-time sun and shade data to its digital billboard network
Digital billboard company LUMO has partnered with SunSeekr to integrate real-time sunlight and shade data into its advertising network. This technology allows brands to trigger specific creative content based on the precise solar exposure of individual billboard locations.
Why it matters
It represents a significant advancement in programmatic digital out-of-home (DOOH) advertising by moving from general weather data to hyper-local, context-aware marketing.
SunSeekr models the sun’s path against building geometry and terrain to calculate where light is falling at any point at any moment. Applied to LUMO’s locations, it produces a continuous solar profile for each site covering sun angle, direct exposure, shade transitions and the hours a screen sits in direct light.
The app launched in London in 2025 and has since grown to more than 350,000 users, reaching #1 in the UK App Store’s Lifestyle category. Its sunlight technology has already been used commercially by global brands including Aperol, which used SunSeekr to connect consumers with sunny hospitality venues across the UK.
