I made & deleted a profile on Facebook ysterday for branding a product. Yelp and google biz as well.

In my experience, it provides little value for startups except in narrow arenas (cause or nprofit/physical consumer product) and is a time sink.

It reminded me of what a pain it was and it was worth having an hour as a sunk cost. If you are raising, it provides a minimal amount of validation and credibility, but time is much better spent elsewhere
