Luke Alexander is a sales trainer and software founder based in Miami, Florida. According to his author page on the Kendo AI website, he worked as a remote high-ticket closer before founding Closer Cartel, a training brand that teaches appointment setting and remote closing for coaching and online-business offers. An October 2023 interview on the Beyond The Wealth podcast describes him as coming from one of the poorest areas of Ohio and moving to Miami, where he runs his companies.
His ventures, as listed on the Kendo AI author page, are Closer Cartel, Closify (a platform connecting companies with sales reps, which he co-founded; tryclosify.com now presents it as DealFuel), AI Insiders, and Kendo AI, an AI sales roleplay and call-scoring platform whose about page gives 2024 as its founding year. The footer of the AI Insiders website states that AI Insiders is a DBA of Closer Cartel LLC.
He publishes on YouTube as @LukeAlexxander (45.8K subscribers and 260 videos, read on September 14, 2026) and on a second channel, @lukealexanderai (6.96K subscribers), which the first one links to. He is also active on X and Instagram as lukealexxander. His recent videos have moved from sales careers toward AI tools and building software businesses.
His current paid offer is AI Insiders. The sales page at joininsiders.ai does not publish a price; the only way in is to book a call. It says members get training on building AI SaaS or service businesses, an AI sales prospecting system, a preconfigured AI agent, more than 120 modules, and coaching. The page claims the team scaled its own SaaS to $1M in annual recurring revenue and lists member income figures; none of these numbers has an independent source. His earlier program, Closer Cartel 2.0, remains on a Teachable school with a curriculum covering the sales process, objection handling, follow-up and finding closing jobs, and a Closer Cartel group is still live on Whop showing 528 members joined. No price for it appeared on either page, and closercartel.com returned a 404 error on September 14, 2026, so it could not be confirmed whether Closer Cartel is still open to new buyers.
Claims about his results come from his own material: the Kendo AI author page says he has trained more than 5,000 sales reps, and the Closer Cartel Whop page says more than 4,000 students. No independent source verifies either figure. The articles about him found in Digital Journal and Men's Journal read as promotional placements, and this profile does not treat them as independent press. A web search on September 14, 2026 combining his name and Closer Cartel with FTC, lawsuit and court found no enforcement action or court case. His year of birth and formal education were not found in any of the sources reviewed.
