**APIs profiled:** 0

letitrain.com was the corporate domain of The Rainmaker Group Ventures, LLC, an Atlanta-based hospitality revenue and profit optimization software vendor serving hotels, resorts and casinos. Rainmaker sold an "intelligent profit platform" built around three products: guestrev for transient pricing and science-based revenue management, grouprev for group pricing and evaluation, and revintel for business intelligence and reporting, with a demand forecast marketed to operators including Caesars Entertainment, Atlantis Casino Resort Spa and Two Roads Hospitality. The company was backed by Norwest Venture Partners and ran offices in Atlanta, Las Vegas, Singapore and Dubai. The brand is retired: letitrain.com now serves a blanket redirect to Cendyn, the acquiring company, its TLS certificate expired in December 2022, and no Rainmaker developer portal, API reference or machine-readable specification was ever published or archived. This profile is retained as a historical, defunct-provider record with no active API surface.
