Calisto Pro is the operations platform built on CalistoOS, the quality-first operating system for properties. It unifies people, properties, devices, and workflows so boutique hotels, property managers, and real estate agencies can deliver consistently excellent stays, showings, and deals from one calm, connected platform that now includes digital keys, smart signals, and around-the-clock human support.
CalistoOS is the quality engine under every Calisto product. Calisto Pro is the operations platform your teams log into every day. Ops sits at the center with Sync, Navigator, Assure, Deals, Purview, Sign, Key, Signal, and 24·7 working together as one stack.
Every booking, inspection, viewing, and contract is a promise to a guest, owner, or client. CalistoOS provides the quality-first operating system. Calisto Pro turns that engine into an operations platform where your teams work every day, and Calisto Key, Signal, and 24·7 extend it into the real world with digital access, live signals, and humans who can act on what the system sees.
CalistoOS is the infrastructure that powers every Calisto product: shared data, standards, automations, and integrations. It keeps property records, people, workflows, and quality rules consistent across your entire portfolio and provides the common language for Ops, Sync, Navigator, Assure, Deals, Purview, Sign, Key, Signal, and 24·7.
Calisto Pro is the application layer your teams see every day. Ops, Sync, Navigator, Assure, Deals, Purview, Sign, Key, and Signal sit on one shared foundation so a change in operations is reflected in channels, guest journeys, inspections, transactions, access, and monitoring without duplicate tools or re-entry.
Calisto 24·7 is the always-on support layer that turns a standard SaaS into a service your guests and owners feel. When a lock fails, a signal fires, or a guest calls after hours, 24·7 sees bookings, keys, signals, and history in one place and can respond with confidence on your behalf.
CalistoOS is the quality-first operating system. Calisto Pro is the suite of products built on top of it. Ops is your core operations workspace. Sync connects channels. Navigator curates the guest and client journey. Assure protects quality. Deals and Purview manage transactions. Sign handles e-signature. Key, Signal, and 24·7 take you beyond software with digital access, live signals from the property, and around-the-clock human support.
The core operations workspace inside Calisto Pro. Shared calendars, unified CRM, tasks, tickets, and simple reporting for every stay, inspection, and showing across properties, portfolios, and offices, all powered by CalistoOS.
Connect OTAs, portals, and websites to a single source of truth. Rates, availability, and listing content stay aligned while bookings and inquiries flow back into Calisto Ops with full channel attribution.
Give guests, owners, buyers, and sellers a clean, branded portal or app for trips, viewings, documents, statuses, messaging, and upsells. Navigator reads from Calisto Ops and works with Calisto Key for digital keys and smooth arrivals.
Standardize inspections, photos, scoring, and condition reports across properties. Issues become tasks in Calisto Ops and every room, unit, and listing has a quality history your owners, brands, and guests can trust.
Pipelines for listings, mandates, offers, and contracts that live in the same system as your operations. Track milestones and commissions while keeping every deal tied to the right people and properties in Calisto Ops.
The client-facing workspace where agents and brokerages send curated listings, organize documents, track next steps, and run e-signing—so clients always know what's happening, what's signed, and what comes next.
Property-smart e-signature for rental agreements, sales contracts, and disclosure packets. Templates pull data from Ops so documents populate automatically with the right property details, guest names, and deal terms.
Turn bookings, showings, and service visits into digital keys that just work. Calisto Key connects your smart locks to Ops, Navigator, Signal, and 24·7 so guests, owners, staff, and vendors get the right access at the right time with a full audit trail behind every door.
Bring sensors, devices, and smart home data into the same story as bookings and quality. Calisto Signal watches for unusual patterns, battery issues, and device health and turns them into clear signals, tasks, and alerts in Ops, Assure, and 24·7.
A human team that sees what Calisto Pro sees and can act on it at any hour. Calisto 24·7 works from the same bookings, keys, signals, and quality records as your internal teams so lockouts, after-hours calls, and urgent issues are handled with context, not guesswork.
Calisto Pro is designed for phased adoption. Most teams begin with a single portfolio, hotel, or office in Ops, then layer on Sync, Navigator, Assure, Deals, Purview, Sign, Key, Signal, and 24·7 where they bring the most visible step up in experience and control.
Start with the portfolio, hotel, or office that matters most. Bring calendars, contacts, tickets, and core workflows into Calisto Ops so your team feels one calm center for the day-to-day.
Add Sync to connect channels and portals, and Navigator to give guests, buyers, tenants, and owners a modern portal or app. The same records in Ops now power distribution and experience.
Introduce Assure to standardize quality, Deals and Purview for transactions, Sign for e-signature, and Key to control digital access. Everything connects to the same bookings and properties in Ops.
Add Signal to watch what devices see, and 24·7 so guests and owners have a trusted human team that can respond at any hour using the same context your internal teams see.
Whether you run a 30-room hotel, a regional property management company, or a brokerage that handles luxury homes, Calisto Pro is for operators who want every guest, owner, and client to feel they chose the right partner.
Replace a patchwork of PMS, inboxes, and manual logs with one operations platform for rooms, tickets, quality, and access. Guests enjoy smooth arrivals, digital keys, and fast support.
