Whistle

What Whistle does

Whistle (legal entity Whistle Messaging, Inc.) is a B2B SaaS company that operates a guest messaging and engagement platform for the hotel and hospitality industry. The firm was founded in 2014, is headquartered in Westlake Village, California with a secondary office in San Diego, and currently runs with 1–10 employees under the parent ownership of Cloudbeds, the hotel management software provider that acquired Whistle to fold its capabilities into its PMS ecosystem. The co-founders, Chris Hovanessian (CEO) and Jonathan Rojas (President), remain in their roles alongside CTO Kevin Riggen, VP of Sales Brandie Jackson, and customer success lead Madison Van Alst.

The core technology is the Whistle Guest Messaging Platform, which enables two-way communication between properties and their guests across the full guest journey — from discovery through booking, pre-arrival, in-stay, and post-stay touchpoints. The platform is modular, with add-on products that include a Digital Guest Book (per-guest portal for registration documents, digital keys, and on-property purchases), Keyless Entry via a FlexiPass integration that automates digital key delivery, Digital Registration for electronic signature collection, and an Upsell & Marketing module that lets properties run personalized campaigns for room upgrades, spa services, and F&B offerings. Whistle's proprietary features are oriented toward ease of implementation and hospitality-specific workflows rather than disclosed AI or ML capabilities, and the firm carries the #1 Best Guest Messaging rating on HotelTechReport alongside HotelTechAward recognition.

Whistle's revenue model is subscription-based SaaS sold through a dual go-to-market motion: an enterprise field sales channel ('book free demo' on trywhistle.com) targeting larger hotel groups and a self-serve PLG motion via app.trywhistle.com for smaller properties. Post-acquisition by Cloudbeds, Whistle's distribution has effectively expanded into Cloudbeds' global hotel customer base, where Whistle functions as the embedded guest engagement module of the parent PMS platform. Pricing is not publicly disclosed. Customer concentration is single-vertical by design — hotels and hospitality operators — with named end-customers not disclosed at the logo level, and with marketing reach extended via Cloudbeds' content properties (HMS Guide 2026, Best HMS Systems).
