Challenges
Kato already ran a powerful web platform, but its mobile experience trailed behind, limiting adoption for brokers and agents who work on the move, while the steps of a commercial property deal, from marketing and matching to negotiation, e-signing, and closing, were spread across disconnected tools rather than one workspace. On top of that, the platform had to scale reliably as adoption grew, modernize aging frontend modules that slowed new feature delivery, and keep listings visible everywhere by feeding them automatically to a wide range of external property marketplaces – all without disrupting live deals.

Delivery Approach
Kato already had a powerful web platform — the challenge was extending it into a seamless, mobile-first experience without disrupting live deals. Intobi delivered that expansion through a phased, cross-platform approach.
Discovery
Intobi began by understanding how commercial property professionals move through a deal and where a lagging mobile experience and fragmented tools slowed them down, then defined an expansion that brings web-grade capability to every device.

All-in-one deal platform
Kato now covers the entire lifecycle of a commercial property transaction in one workspace — a single tool that handles marketing, matching, tracking, negotiation, e-signing, and closing, streamlining the entire commercial property workflow.
More user-friendly platform with expanded features
Intobi redesigned the interface and added new tools to make every task faster and simpler: an intuitive mobile-plus-web UI lets users switch devices without relearning workflows, and an expanded toolset — CRM widgets, task automation, and smart notifications — keeps the entire transaction in one hub.
Improved frontend of the platform
Customer-facing upgrades increase reach and insight without extra effort: email campaigns and insight reports let users launch targeted outreach and view real-time engagement metrics in one dashboard, while marketplace integrations automatically feed listings to OnTheMarket, Property News, PropertyPal, BPI Expresso, Imovirtual, Idealista, and eGO Real Estate.
The core platform's backend architecture
Intobi reinforced the engine powering Kato so it scales smoothly as adoption grows: data-rich Chart.js dashboards turn raw KPIs into at-a-glance trends, bulk publishing to Radius rankings keeps portfolios visible on industry benchmarks, and Mapbox GL geolocation delivers high-precision maps and spatial search.
Results
The mobile expansion and platform overhaul delivered measurable gains in adoption, reliability, and revenue: a migrated React module that loads faster and is easier to maintain, a larger blended team shipping features continuously without disrupting live deals, and expanded capability that lifted revenue per customer by 20% alongside stronger platform engagement.
