Their thesis, in full

Montreal-based venture studio and early-stage VC affiliated with Sagard. Diagram builds and invests in fintech and climatetech companies across Canada and the US, from pre-seed to Series A, either leading rounds or investing alongside other backers. Its distinctive model is co-building companies from zero alongside founders, in the tradition of a true venture studio rather than a passive investor. Its most recent vehicle is an $80M CAD ClimateTech Fund closed in 2024. Notable studio companies include Dialogue (acquired by Sun Life) and Collage (acquired by People Corporation).

What they bring past the cheque

  • Venture studio support
  • Sagard ecosystem

  • ClimateTech vehicle

Questions they usually ask

Have an answer ready for each one before the first call.

  1. When does Diagram act as a pure investor versus a venture-studio co-founder?
  2. What does Sagard's broader ecosystem (asset management, financial services) unlock for portfolio companies?
  3. How does the dedicated ClimateTech Fund interact with the main fund for follow-on rounds?

Follow-on

Diagram maintains follow-on capacity across its core fund and a dedicated $80M CAD ClimateTech Fund, supporting both standard and climate-specific rounds.
