Knowlify

Knowlify is a Y Combinator-backed, AI-native ad agency that produces about 25 finished video ads a week (AI UGC, animation, AI commercials) and can manage Meta campaigns on Facebook and Instagram, or supply creative only.

Knowlify is an AI-native ad agency for companies that advertise on Facebook and Instagram. Instead of selling software, it operates as a service: a small team produces finished video ads at a pace of roughly 25 per week and, if the client wants it, also runs the agreed Meta campaigns. The company is backed by Y Combinator and started life as a self-serve explainer video app, which now remains available only to existing customers. The creative output falls into three styles. AI UGC covers testimonial-like, straight-to-camera ads built around the real product. Pixar-style animation uses original characters and short story beats, and makes up about half of what the team produces. AI commercials recreate scenes, sets and product shots that would normally need a crew and a location. AI handles much of the production, while people direct the concepts, edit the footage and check every ad for how it reads in the feed. The engagement follows a fixed rhythm. A 20-minute kickoff call covers product, audience and goals, written direction (angles, hooks, scripts) arrives within about 48 hours for approval, and the first batch is promised on day 5. New batches then arrive weekly, informed by test results, with minor revisions returned within 24 hours. Clients keep ownership of their ad account and every finished ad, media spend is paid separately, and there are no per-creative charges or annual contracts. A 90-day guarantee offers a refund if the ads do not earn more than was paid, subject to the written agreement. Knowlify suits B2B and B2C companies running paid social that need more video variants to test than an in-house team can produce. It is a poor match for a single hero brand film, for very small budgets, or for teams that already have an editor and only want self-serve software. Against creator marketplaces, freelancers and AI video tools, its distinguishing trait is that one team owns scripting, production, quality control and, optionally, the campaign results that shape the next batch. Pricing is quoted privately per scope.
