Teams can install it with a copy-and-paste code snippet, and GrowSurf says a referral program can be launched within a day. It lists 61 integrations, including Stripe, HubSpot, Salesforce, PayPal, Zapier, and webhooks, alongside a REST API, webhooks, SDKs, API libraries, embeddable elements, and an MCP server.
