Feder is business data monitoring. Analytics, CRM and ad tools count whatever reaches them. Feder checks root events like payments, bookings and form fills at the source, learns each business's own normal, flags breaks or quiet periods, and says "Still learning" instead of guessing. It works with tools like Google Analytics, Stripe and HubSpot. Read-only: you approve each app, disconnect any time, and it doesn't replace your tools. Free checks weekly. Circle checks daily, with daily alerts and 24 months of history, and starts with 14 days free.
