I don't know which startup pitches are the best, but here's a list of the worst ones to avoid at all cost :) https://www.inc.com/matt-hunckler/startup-pitches-that-fail-...

Thanks for all the responses :) . I'm also putting together a Telegram group - where founders can get their pitches reviewed by other founders.
