[Company & Contact](#company--contact) --- ## Company Overview **Legal name**: ONDA Inc. **Founded**: 2016 (10 years of channel operating track record) **Headquarters**: 17F Victoria Building, 327 Teheran-ro, Gangnam-gu, Seoul 06236, Republic of Korea **CEO**: Hyunseok Oh (오현석) **Mission**: Enable every accommodation, regardless of size, to operate and distribute like a major hotel chain — and to be discoverable and bookable in the AI era. ### Key Metrics - **54,416** accommodations connected to ONDA HUB - **615,529** rooms connected - **3,287** active ONDA Plus properties - **75** sales channels under master contract - **2M+** bookings processed annually (**8,988,610** cumulative since 2016) - **<0.003%** overbooking rate (industry avg: 2–5%) - **99.9%** system uptime - **12,000,000** API calls processed per month - **10 years** of channel operating track record ### Core Competencies 1. **Channel Strategy & Management** — master partnership agreements with major global and Korean OTAs; one ONDA contract grants access to all 75 channels. 2. **Real-time Inventory Optimization** — direct PMS synchronization, bi-directional instant updates, intelligent overbooking prevention (<0.003%). 3. **AI / Agent Readiness** — booking engine and Schema.org structured data tuned for ChatGPT, Claude, Perplexity, and other AI agents; native MCP (Model Context Protocol) server. 4. **Hybrid Integration** — Enterprise customers can keep their own PMS/CMS and outsource only the channel infrastructure via the Connectivity (CMS) API. 5. **Technology Infrastructure** — 99.9% uptime, real-time webhooks, enterprise-grade security. --- ## Core Advantage: Direct PMS Integration ### Why PMS-Direct Matters ```mermaid flowchart LR PMS[Property PMS] -->|Direct, real-time| HUB[ONDA HUB] HUB --> CH[Sales Channels] HUB --> API[API / MCP] ``` **Traditional aggregators** cache data from OTAs (delayed, sometimes hours old), estimate availability, and risk overbookings. **ONDA is PMS-direct**: live data from the property's actual reservation system, a single source of truth, real-time inventory state, and an industry-leading <0.003% overbooking rate. ### Data Quality - **54,416 direct connections** — live operational data, not cached estimates - **Bi-directional sync** — instant updates both ways (PMS ↔ ONDA ↔ channels) - **Real-time accuracy** — inventory and rates reflect actual property state - **Verified inventory** — actual room availability, with overbooking prevention --- ## Products & Services ### ONDA HUB (Channel Manager) Next-generation channel manager platform connecting 54,416 properties to 75 sales channels through one integration. Single update → all channels synced; one booking → centralized across PMS and channels. Includes master partnership agreements so a property signs one ONDA contract instead of negotiating each channel individually. ### ONDA Plus (All-in-One for Individual Accommodations) All-in-one operating platform for pensions, pool villas, B&Bs, guesthouses, motels, and small-to-medium hotels. Bundles **PMS + Channel Manager + AI-friendly Booking Engine + AI guest acquisition**. 3,287 active properties. Core modules: Channel Manager, Booking Engine, PMS, and AI OTA guest auto-reply. ### ONDA Enterprise (CRS) CRS-grade reservation solution for hotel chains and multi-property operators. Centralized inventory, cross-property booking, corporate rate management, role-based access, property-level autonomy with central oversight, and custom SLA. ### ONDA Connectivity API (CMS API) Build on top of ONDA's channel infrastructure. Two usage models: - **Add-on (Enterprise)** — hybrid integration: keep your own PMS for operational control, let ONDA handle channels. - **New build (Developers)** — build a channel-manager product in 1–2 weeks instead of a decade (`/developers/connectivity-api`). ### ONDA BookingOn Direct booking marketplace connecting travelers to accommodations, with Google Hotels integration and real-time PMS availability. It has no standalone page on the site — it is covered under Enterprise, and `/booking-on` redirects to `/{locale}/enterprise`. ### Booking Engine White-label, commission-free direct booking website for properties. Custom domain, SEO- and AI-optimized, 25+ guest languages, real-time PMS sync, 1-minute installation via a code snippet. Typical outcome: increased direct bookings and reduced OTA dependency. --- ## API & MCP Integration ONDA provides **REST API + MCP (Model Context Protocol)** so developers and businesses can build hospitality applications on top of ONDA's supply network. **Integration options:** - **Vendor API** — REST API for accommodation suppliers (property registration, inventory, booking processing). Docs: vendor.dapi.tport.dev/docs - **Channel API** — REST API for online sales channels (search supply, process bookings). - **MCP Server** — LLM-native integration for AI agents and chatbots: natural-language hotel search and booking. Compatible with Claude, GPT, and other LLM platforms. - **Connectivity API** — build your own channel manager (see model ② above). **Scale**: 12,000,000 API calls/month, 99.9% uptime. Real-time webhooks for `booking.created`, `booking.modified`, `booking.cancelled`, `inventory.updated`, `rate.updated`. > API/MCP pricing is determined by usage model and is provided during consultation. Connectivity (CMS) API pricing is confidential (B2B2B partner-margin protection). --- ## Distribution Channels ONDA connects properties to **75 sales channels** under master contract, organized into 8 categories: | Category | Representative channels | | --- | --- | | Global OTAs · Metasearch | Booking.com, Agoda, Expedia, Airbnb, Trip.com, Hotels.com, Google Hotels, Trivago | | Korean OTAs · E-commerce | 네이버, 여기어때, Coupang, G마켓 | | Travel specialists · Cross-sell | Travel agency networks, packaged-travel partners | | B2E · Corporate welfare · Partnerships | Employee-benefits and corporate booking marketplaces | | Regional tourism | Local-government tourism platforms | | Pet · Kids · Leisure | Vertical leisure channels | | MICE · Business | MICE and business-travel channels | | Associations · D2C | Industry associations, direct-to-consumer | > Exact channel list and policies are disclosed during a sales inquiry.

English, Japanese and both Chinese scripts are full translations of the whole site — every `/{locale}/…` route resolves under `/zh-Hans/` (Simplified, mainland vocabulary: 酒店 · 渠道 · 软件) and `/zh-Hant/` (Traditional, Taiwan vocabulary: 飯店 · 通路 · 軟體, also serving HK/MO), blog and pricing included. The two Chinese versions are separate translations, not character conversions of each other. Region codes redirect to the script code: `/zh-CN/` and `/zh-SG/` → `/zh-Hans/`; `/zh-TW/`, `/zh-HK/` and `/zh-MO/` → `/zh-Hant/`. - This file is generated at build time from the site's own pricing and metrics sources, so the figures here match what the website displays.
