I'm doing a startup that is in a very early stage and in a niche sector. I think that VCs in this niche could potentially be interested in meeting me, and I would also benefit a lot just by running what I'm doing by them - I have general VCs reach out to me all the time because they somehow gathered that I'm doing a startup, but no one in my niche. Is it worth reaching out to the niche VCs even if I'm not ready to raise funds? Or would they not want to meet me if that is the case?
