Are there any start-ups that specialize in helping other start-ups with their marketing needs? Maybe a start-up running based on a Marketing as a Service (MaaS) model?

Hubspot may be a way to go depending on the stage you are at.

I'm a marketing consultant so maybe I can help point you in the right direction, but... Can you specify what kind of needs you have? "Marketing needs" covers a huge swatch of things.
