For founders building massively scalable, science and technology-based startups.

The Prime (General Technology) Stream at CDL-Toronto was launched in 2012 and will accept its 8th annual cohort in 2019, doubling its size to admit 50 ventures. The stream brings together many of the CDL network’s most experienced entrepreneurs, investors, and scientists from diverse fields including enterprise software, nano-materials, fin-tech, consumer products, and augmented and virtual reality. CDL startups work with these 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 2019 and June 2020. CDL is a non-profit organization. There are no fees for participation and CDL does not take any equity. Learn more about the CDL program.

“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.”
