Where's the best place to find B2C (Seed to series B) online businesses?

Are there any good lists/resources of serious B2C businesses that people can think of this is for my business referralhero.com

I'm thinking things places like Crunchbase, Slack channels etc. Any newsletters I could join?

I had a trawl through Crunchbase but there was a lot of B2B which isn't as relevant to us.

Our ideal customer is a Seed - Series B online business.
