Jonatan de Boer

After having fulfilled various roles in marketing and sales, Jonatan de Boer brought the fast-growing German startup 'Mediakraft' to the Netherlands in 2013. As a MultiChannel Network (MCN), this company bundled hundreds of YouTube channels, creating an interesting proposition for YouTubers and for advertisers. In addition, Mediakraft produced several proprietary formats on YouTube and initiated extensive influencer marketing campaigns and video productions on Instagram, Snapchat and TikTok.

Jonatan sold Mediakraft's Dutch and Belgian  division in 2016 to television producer MediaLane. From this acquisition, the company emerged as a social studio. Customers such as Coca-Cola, The Walt Disney Company, Talpa, Telenet, NPO and Vodafone were provided with innovative productions and influencer marketing campaigns. In 2018, Jonatan left MediaLane to join Los Angeles-based tech startup 'Bird' to lead their Northern European operation until Bird's IPO in 2021. Jonatan now advises media companies and public figures on their digital media strategy, content, formats and positioning. Including social media, podcasts and VOD.
