Sometimes, when you meet with your investor, if there’s no specific agenda, your investor really just wants you to teach them things you’ve learned about your business. It’s for several reasons: sheer curiosity (the golden driver of any good VC), to hear how your business is doing (legitimate portfolio update), and because they actually learn through their founders - this is literally how they level and build (second-hand) experience.
From a social capital perspective, VCs like to have real information to share in conversations. Not specific privileged information that should be kept confidential, but information that was earned through blood, sweat and tears (and no, it is not a cost they want to bear themselves) and therefore is more valuable.
Have a cool acquisition you just pulled off? Had to fire a cofounder? Learned something interesting about the power dynamics within your B2B sales meetings? Tell them! If they’ve been there before, they can give you insight you wouldn’t have thought of otherwise. If they haven’t been there, they want to know! If they both haven’t been there, and don’t really care… yeah I’m sorry they’re probably just not worth their salt. Not much you can do at this point.
