risk level indicator at Medium level

The Legal Risk Score of a Co-Founder Agreement Template is Medium

Our legal team have marked this document as mediun risk considering:

  • The requirement for unanimous consent for significant decisions, including additional capital contributions and amendments to the agreement, could lead to operational gridlock if co-founders disagree.
  • The assignment of all intellectual property to the project without provisions for compensation beyond equity share may not adequately reward individual contributions, especially if the project's value does not increase as expected.
  • The non-binding nature of the agreement means that the commitments made are not enforceable in court, which could result in uncertainties and reliance on good faith among co-founders.
