For founders pursuing commercial opportunities that exploit the recent drop in the cost of accessing space and enable humanity to benefit from space-based technologies. 

The Space Stream at CDL-Toronto brings together astronauts, entrepreneurs, investors, and scientists from fields related to space exploration and transportation, satellite communications, Earth observation, automation, and robotics. CDL startups work with these mentors to sharpen objectives, prioritize time and resources, raise capital, build networks and engage with experts working on the frontiers of research.

The startups attend five 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. Learn more about the CDL program.

Who Should Apply?

The Space Stream is particularly suited to coachable startup companies who are applying artificial intelligence and other advanced technologies to exploit commercial opportunities related to space and space-based services. 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. Companies from more than 15 countries have participated in the program.

Example Innovation Areas:

  • Satellite communications
  • Earth observation
  • Positioning, navigation, and timing
  • Software and AI systems
  • Robotics and automation
  • Computing and data processing
  • Materials and energy solutions
  • Space logistics and manufacturing
  • Satellite hardware (i.e. sensors, antennas, chips, propulsion)
  • Planetary exploration and interplanetary transportation

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

“We are explorers and it is inevitable for humans to travel beyond our planet and build civilizations elsewhere. This is a challenge that is important for continuity of life for our species. CDL Space is the first coordinated effort by an entrepreneurship program to support the formation and scaling of next-generation space ventures that will help us realize this future.”
