Not all influencers have millions of followers. In specialized and B2B markets, a highly valuable influencer may attract a relatively small but intensely loyal following. Your influencer could be a subject matter expert, an industry chief executive, or a prominent customer.
For example, within your company there may be folk who almost certainly do not think of themselves as influencers and yet could generate very valuable content for your campaigns. Or you may know customers with nice things to say, if only they found the words to say them. We can help you with that!
