DRMetrix has eight employees who will join iSpot, which now has 278 employees across Bellevue, Wash., New York City, and Los Angeles — nearly double its headcount at the end of last year.
Earlier this year iSpot acquired Los Angeles-based Ace Metrix, another TV ad measuring company.
Founded in 2013, iSpot now helps more than 450 brands measure TV advertising across various viewing formats in real time. The company raised a $30 million round in 2018 and has reeled in $57 million to date.
iSpot said its revenue growth and retention rates are up over the past year. The number of brands that have annualized subscriptions has doubled since 2019.
“iSpot is constantly investing in the development and acquisition of technologies required to accurately measure the TV advertising of tomorrow,” Sean Muller, founder and CEO of iSpot, said in a statement. “DRMetrix has developed unique and real-time measurement capabilities around creative versioning and dynamic advertising that will become increasingly important as the TV ad market evolves.”
