Kevin O'Leary Calls Pay-Per-Customer Social Media Video Services "the Best Side Hustle There Is"

Kevin O'Leary says the best side hustle available right now is using a phone to make short videos that bring customers to local businesses, according to TheStreet. In a December 2025 post on X, the "Shark Tank" investor said creators can charge businesses $100 for every buying customer they acquire through social media.
At $100 per buying customer, reaching $10,000 would take 100 conversions, or roughly three to four a day for a month, according to the article. O'Leary said many business owners have no idea how to use social media, and that understanding how to make content for it is "the best side hustle there is."
The article notes that customer acquisition costs for local services often run past $100, and that home service trades such as HVAC, plumbing and roofing frequently see costs of $150 to $350 through paid channels. It adds that results depend heavily on the business, the offer and how well conversions are tracked, and that low-margin products may not support a $100 fee.
