Home Who We Are

We are curious

At Plum we love to dismantle things and understand how each gear works, both on the tech and the business side

Plum Research started in 2015 as Siphonics
- a side project at Red Sky.

Our aim was to solve ongoing B2C software subscription churn and find a new monetization strategy within the music business.

Siphonics aimed to assist the music revolution with its data and support the transition from downloads to streaming. While still at Red Sky, we decided to do business as Plum Research. In 2016 we were recognized as one of the world’s 20 hottest music startups by MIDEMLAB in Cannes.

Since 2016 Plum started its transition towards televison, film and gaming by providing top Hollywood studios and global broadcasters with rich audience measurement data.

In 2017 we closed our first high ticket multi-year deal with a blue chip client and secured a funding round from Tar Heel Capital Pathfinder.
