Bigger clients have a much larger sales cycle, but if you ever get a 'whale' account, they could serve you for years. I always went after the hardest to get whale accounts and it's such a huge payoff.

Last one will be much better so that we have experience of both the kinds of clients.

Don't mix both because in most cases they have very different needs 😄 And coming from someone who has almost lost his company when 'rona started. It's better to have as many different clients as you can get, that way it's easier to diversify and build a more redundant system 😄
