The short answer
A BASECAMP* 37SIGNALS charge is a project management and team collaboration subscription from 37signals LLC.
Why it shows up like this
A line item on your bank or credit card statement reading BASECAMP* 37SIGNALS indicates a software subscription charge from 37signals LLC for the Basecamp Project Management Platform. The company develops team communication software that combines message boards, to-do lists, group chat, and file storage into a shared workspace. Descriptors on banking portals typically display as BASECAMP* 37SIGNALS, 37SIGNALS LLC, BASECAMP.COM, or BASECAMP PRO.
This charge appears when an active workspace renews or after a 30-day free trial period ends and converts into a paid subscription. Billing depends on the plan you selected: a per-user tier priced at $15 per user each month, or Basecamp Pro Unlimited at $299 per month billed annually. If you do not manage Basecamp yourself, a coworker or contractor may have used your card to coordinate client projects.
To review the billing history or cancel the service, sign in at launchpad.37signals.com. Open the Adminland menu in the top right corner and navigate to Upgrade, invoices, and payment details. From that screen, you can inspect your active user count, download invoice receipts, or click Cancel your account or put on pause to stop all future billing.
37signals LLC maintains a flexible refund policy. If an automatic renewal processed after you stopped using the platform, send an email to support@basecamp.com with your account details to request a prompt refund. If you do not have an account and suspect card fraud, notify your credit card issuer to dispute the unauthorized charge and request a new card number.
