For early-stage founders developing state-of-the-art technological innovations across diverse industries to build companies that scale massively.

Distinct from the specialized streams, the Prime Stream at CDL-Toronto is not focused in a specific field but rather admits ventures in diverse technology areas. Prime ventures include those with strong technical & coachable teams, differentiated technology, and working in multimillion-dollar industries.

CDL startups work with mentors to sharpen objectives, prioritize time and resources, raise capital, and engage with experts working on the frontiers of research.

The startups attend five in-person objective-setting sessions between October and June. CDL is a non-profit organization. There are no fees for participation and CDL does not take any equity.

Who Should Apply?

The Prime Stream is particularly suited for founders pursuing state-of-the-art technological innovations across diverse industries. This stream is tailored towards early-stage companies (early venture or growth) or even projects (pre-incorporation); however, startups at all levels of maturity will be considered.

Example Innovation Areas

  • Enterprise Software and SaaS
  • Retail and Consumer Products
  • Robotics and Sensors
  • Smart Cities and IoT

The list above is not exhaustive. Contact to discuss the program and your venture with someone from the Prime Stream.

Our Mentors

CDL mentors include accomplished entrepreneurs, experienced operators, active angel and venture investors, world-leading scientists, engineers, and economists. Mentors meet every eight weeks in Toronto to help founders set objectives over the program’s nine-month duration.

Companies accepted to the CDL Prime Stream benefit from accomplished entrepreneurs, experienced operators, and active angel and venture capitalists.

Accepted companies have also access to CDL’s Scientists and Economists that help them tackle technical and business challenges.

“As an early-stage startup in a highly competitive space, the wisdom, ideas, and advice offered by the Fellows and Associates have been unequivocally invaluable and helped shape our direction and refine our focus. Many of the Fellows and Associates have also kindly and enthusiastically supported our seed financing, for which I am truly grateful. I would especially like to thank Ted Livingston, who has so generously given countless hours of his time working with me to get Interaptix to where it is today.”
