SellHax is a marketplace for buying sponsored articles, press releases, newsletter, podcast and creator placements on verified publications, with payment held until each placement is live and AI visibility tracking. Publishers set their own prices and prove they own their sites. Buyers see every price up front, with one service fee shown as its own line. An AI planner builds a media list from your goal and budget, and SellHax checks every week whether assistants like ChatGPT and Claude mention your brand. Founded in 2025 in Hyderabad, India.
