Extole

Extole is an enterprise platform for running referral, loyalty and incentive programs, used by Discover, Bose, Ancestry, Cinemark, Athleta, ASICS, Lovesac, Wine.com, Princess Cruises, Tatcha and a cluster of fintech names including Tally, DailyPay and Go2Bank.

Its distinguishing feature is running many programs at once rather than one. Flow Builder creates each program, Reward Bank manages the incentives across all of them, and personalisation targets different offers to different segments, which is how a large brand runs a refer a friend program, a loyalty tier and a seasonal incentive without three vendors.

The developer surface is unusually complete for this category: a full REST API with OpenAPI specifications, native SDKs for iOS, Android, JavaScript and React Native, CLI access, a mobile app, and an MCP server that lets teams operate the platform through AI assistants including Claude and ChatGPT. That last one is rare in marketing software and genuinely useful for reporting and campaign checks.

Compliance covers ISO/IEC 27001 certification, GDPR, CCPA and the EU-US Data Privacy Framework, with scoped permissions and audit logging, which is what gets it through procurement at banks. Pricing is not disclosed and engagements are enterprise scale. Its documentation and OpenAPI spec are public, so engineering can scope an integration before you talk to sales.
