Attendance at the virtual orientation session is mandatory. Other offerings are 1:1 and tailored to the founder and occur at the founder’s convenience. Founders may participate in as many or as few offerings as are helpful to their venture’s trajectory and needs. Some group sessions are offered, however the focus is on sharing resources with founders that are personally tailored and highest impact for time invested.
