Hear what it's all about from our alumni & Investors

  • "The greatest benefit we got were the amazing brand introductions and other connections. The breadth of experience of the team and mentors allowed us to validate our assumptions, and very often to then refine them." - Dibbz
  • "The mentoring process has been a fantastic accelerator for the business. It's much more about the mentor being on our side of the table, partnering with us and working through the issues than a normal supplier/customer relationship." - Miappi
  •  "It has been without question, the best decision and most rewarding experience of my career, and I would wholehearted recommend Collider to any start-up." - LivingLens
  • "Collider accelerates very high quality startups with a strong relevance to our brands." - Marc Mathieu, SVP Global Marketing, Unilever
  • "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."
  • "We received direct access to senior leaders throughout Unilever. The opportunity to validate and challenge our assumptions was transformational for our business. We're now working directly on a global project with the CTO and Beem is the cornerstone of the communication strategy."
