@HN: I tried to summarize the biggest lessons learned that came to my mind - pretty sure i missed a lot.
Please add here which recommendations to startups you would have - i add them to the post afterwards!
My startup focuses on peer-to-peer mentoring so a lot of what you described in the post applies to what we try and implement in our group setting. Thanks for the tips!
but at the events they usually try to get mentors that fit to the startups but keep the format as mentioned in the article.
during the acceleration time they usually pair them with specific mentors/advisors - but this usually needs to be pulled by the teams as well. (seedcamp and 500 do this very intensively imho)
