An AI-powered tool, designed for hair professionals, was launched in August 2025. This tool offers precise hair color mixing ratios, benefiting both experienced stylists and those less comfortable with color mixing. It quickly gained paying subscribers organically, using no paid advertising. Operating with a recurring subscription model, the service has extremely low operational costs. Revenue is primarily generated through monthly subscriptions with automatic billing. Discoverability stems from organic search, social media presence on platforms like TikTok and Instagram, Pinterest boards, and word of mouth. Subscribers find value in the tool for its efficiency during consultations and lack of competition. Operating the business requires around five hours weekly, focusing on customer support and occasional social media content. The tech stack includes services like hosting, email marketing, and AI capabilities, while the business runs autonomously without external staff. Potential growth avenues exist, including paid social ads, email marketing, and partnerships with educational institutions. Other opportunities include introducing referral programs and diversified pricing models. The business, built as a side venture alongside other enterprises, experienced rapid growth. Despite its success, the owner is selling due to commitments to other businesses. Assets transferred in the sale include the domain, codebase, customer data, subscription accounts, and social media presence, along with 30 days of post-sale support. The ideal buyer could be a beauty industry professional, a SaaS acquirer, or a marketer. At $19,000–$22,000, the business has an average monthly profit of $475, minimal technical requirements, and offers significant room for growth.
