Indie hacker Marc Lou announced the first paying customer for his new product Stalkr, a social listening tool for startups. Stalkr tracks mentions of your brand, product, competitors and keywords across X, Reddit, YouTube and LinkedIn, helping teams reply, fix bugs, find product ideas and catch testimonials early. It offers 100 free mentions with no credit card required, and the landing page shows a live mention feed. Another fast ship-to-revenue one-person-company case study.
