Plixi

Plixi is the leading Instagram growth service allowing users to grow their audience organically, using patented audience growth technology. The job it does: running campaigns, content and ads for clients who do not have an in-house team.

It makes the most sense for small and mid-sized businesses. They also list Advertising, Machine Learning, Social Media Management and Social Media Marketing, so expect those to show up in the feature set. They are a small team, 11 to 50 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

Plixi is based in San Diego, California. Their site is plixi.com.

Things worth asking about: who does the work day to day, reporting cadence, and contract length. Ask for a trial on your own data, not a canned demo.

If you have worked with Plixi, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
