About Us

Collider is the first startup accelerator to focus on building startups in the Madtech sector.


Our last three cohorts of startups have been helped along the way by our network of investors (many of whom are entrepreneurs in the sector), brands (such as Unilever, The Nationa Lottery and Puma) and agencies (such as Ogilvy & Mather Group UK, Engine Group and DigitasLBi).

This network has helped them to build their brands, shape product, define pricing and get their first trials.

And now we want to turn up the volume and expose the brightest and the best of these startups to additional expertise, so they can compete on a global stage and cement our reputation as the global leaders in marketing and advertising.

  • "The support network and the potential of the contact base that Collider brings to the table cannot be overvalued. The whole experience has been a vital factor in the success that we have achieved so far with CampaignAmp."
