Launched in 2011, Captify offers brands, advertisers and agencies the ability to target consumers at the point of intent by serving display ads based on their searches through Google, Yahoo and Bing.
The agency will work directly with Joseph and Ludwin and Captify’s senior management team, reporting to COO Vincent Potier.
Potier said: "We chose Speed because of its undeniable passion for our business and understanding of the technology market. We’re growing rapidly and need a strong and enthusiastic team with exceptional knowledge of the broad media market, strategic vision and operational excellence."
Work will focus initially on the UK and then Europe, with Speed ensuring that Captify is "talking to the right people, agencies and marketers", said Speed director John Brown.
The appointment follows Captify’s successful seed funding round of £1.2m with Panoramic Growth Equity to fuel growth in the UK and Europe. It is the first time the start-up has sought agency help and follows a pitch involving a number of other agencies.
Meanwhile, the agency has also added to its media portfolio, picking up project briefs to promote the FT-owned Investors Chronicle and sports news agency sntv, a partnership with IMG Media and The Associated Press.
Speed was handed the Investors Chronicle brief without a pitch. It will work closely with the publication's commercial and editorial team to publicise content and profile its journalists to increase brand awareness of the title among a wider audience.
The sntv brief expands Speed’s existing work with the Associated Press. The agency is tasked with profiling executives, communicating its business development and showcasing sntv’s sports focus, heritage, tailored services and global reach.
