How much time do I need to commit to being a mentor?

It depends on how much time you’re ready to contribute. Mentors participate on a flexible basis, engaging with startups ad-hoc as needed and desired, for whatever time period you choose. We ask that all mentors be available for at least one hour per month. Requests may vary from month to month, and our team is flexible if there are temporary changes in your schedule. You can learn more about expectations for our mentors here.

You will match with startups in a few different ways:
  • We will proactively connect you with startups based on your skills and what our startups need.
  • You find startups of interest. If you’d prefer, we wholeheartedly invite you to look at the list of startups, message folks on Slack, be an active community member, join social hours, and meet startups organically. Feel free to reach out to anyone you think you can help. This is an open, welcoming community.
  • Startups can request to connect with you through our introduction platform. Based on your interest and availability, you will have the option to accept or reject the request.
