What kind of help can I expect from the XX Mentors?
Besides your Lead Investor, a pool of XX partners are also available to help.
In the spirit of under-promising and over-delivering, you should not expect help from any particular XX partner who is not your Lead Investor. These are all busy people - many of which are actively running their own companies - who are making different time commitments.
However, these are all experienced founders who love helping other founders. If you make a reasonable ask every now and then, there is a good chance someone will help. If you form a real human connection with one, they will likely help even more.
