ColdCallGym is an AI-based sales training platform designed for reps to practice cold calling with AI-generated prospects via a phone line or browser. Every call is transcribed, evaluated on key skills, and followed by personalized coaching, simulating flight training for sales. The "Go Live" feature allows users to make real cold calls while receiving real-time AI coaching. Since its launch in 2025, ColdCallGym has attracted numerous users and offers a subscription model via Stripe with different membership levels. The business model is freemium SaaS, offering a free trial and several paid plans, and it includes a revenue-boosting "Go Live" add-on. Key metrics highlight over $2,000 in revenue since 2025, hundreds of active accounts, and thousands of practice calls completed. The package for sale includes a comprehensive tech stack, a real-time voice system, AI-powered coaching and analytics, a dedicated phone and SMS system, admin capabilities, gamification features, and integrated marketing tools. Operations are mostly automated, requiring roughly five hours weekly for marketing. The primary customers include sales reps, founders, and agents who convert from free users to paid subscribers. Revenue has been stable, backed by a lean cost base. Growth opportunities exist in upselling "Go Live," enhancing team sales, capitalizing on paid acquisition, expanding content and SEO, forging partnerships, and exploring new verticals. The sale is motivated by the founder's transition to a new full-time project, offering a buyer a ready-to-scale SaaS business with a stable income and strategic growth opportunities.
