For startup founders, particularly those in early- to mid-stages of development, appointing an influencer (one with tangible business experience, of course) to be part of your content team is a marketing tactic that's very rarely used.
Temporarily hiring an influencer to promote your product is one thing, but what about hiring one to be a full-time employee? For startups, traction is difficult. For influencers, steady income is unlikely. This makes the role a potential match made in heaven for the startup, which will receive immense brand exposure simply from the influencer letting their audience know where they're working.
