2024: a free/cheap Chrome extension validates demand (~1,000 installs). 2025: Facebook's automation crackdowns made the extension model risky, forcing the pivot to a fully managed server-side service at $149/mo — the extension listing now literally warns users and upsells the Professional plan. Growth stack since: keyword-targeted SEO blog, comparison pages, llms.txt, in-product referral credits, and eating their own dogfood (the Growth plan includes the team responding to Facebook posts within 60 seconds — the same channel they prospect with). High-touch model: 157 subs at ~$167 average, 85% margin.
The original product is now the funnel: the Groups Watcher extension (~1,000 users, 4.4★) still monitors Facebook groups with keyword alerts, but its own listing warns that Facebook may restrict personal-account automation and steers installs to the $149/mo server-side Professional plan.
49 blog posts targeting lead-gen keywords ("lead-alert-software", "how-to-get-leads-from-facebook-groups"), 14 integration docs (Zapier, Slack, webhooks), 3 comparison pages and an llms.txt for AI crawlers — 82 URLs total.
The company prospects with the channel it sells — demand was validated "through their own lead generation work and testing with hundreds of clients" (company claim, unverified), and the thesis on the about page is that "the business that responds first to Facebook group posts usually wins the lead". TripAdvisor and national HVAC businesses are showcased as clients.
Referrals pay in product, not cash: 10 group credits (framed as ~$1,800/yr in value) per referred Professional signup, both parties must hold active subscriptions, attribution is manual — a retention-flavored referral loop for a high-ticket service.
