Tidying guru Marie Kondo believes that if it doesn't spark joy, you should get rid of it. In our AI business, we get little joy out of unnecessary expenses, so we make it a habit to declutter them on a regular basis. Any artificial intelligence (AI) or machine learning (ML) business owner will tell you that AI can be an expensive habit. Left unchecked, the costs of those pet projects, support services and data-storage needs can take over your profit & loss (P&L) statement with all the exuberance of a pile of unread New Yorkers. This is especially true as your business starts to rapidly scale, and the result can leave you sitting less than pretty.
