What OneCity does
OneCity, operated under the legal entity NZT Ltd (registered in England and Wales, headquartered in London at 124 City Road), is a spatial data analytics SaaS platform serving property developers, investors, and entrepreneurs in South Africa. The platform, branded OneCity Insights, aggregates cadastral, zoning, environmental, and market data from multiple municipal GIS portals, the Deeds Office, planning documents (including SPLUMA, the Johannesburg Spatial Development Framework 2040, and Nodal Review), and property marketplaces into a single interactive map at map.onecity.dev. It enables users to filter sites by planning constraints, zoning, and incentives; rank them using proprietary indices (Development Impact Gauge, Public Transport Accessibility Index, Local Amenities Index, and Parcel Shape Index); and generate instant Site Reports and 600-meter Area Reports for due diligence.
The underlying technology stack combines spatial analytics with computer vision — leveraging Microsoft's Building Footprints AI dataset cross-validated against GeoLIS footprints to estimate existing built-up coverage against permitted coverage — and pedestrian-network routing for 15-minute accessibility calculations. Current coverage spans the City of Johannesburg (181,753 identified opportunities for single-family detached housing, with 2,452 flagged as high-potential) and the City of Ekurhuleni (~600,000 plots, ~250,000 opportunities, ~12,000 high-potential sites), with content marketing via the monthly 'Unlocking Johannesburg' newsletter on Medium driving top-of-funnel awareness.
The business model is a self-serve SaaS subscription delivered through a product-led growth motion; pricing is not publicly disclosed and access is currently gated through a website waitlist, indicating an early commercial stage. Customer segments span five personas — primary users are property developers and entrepreneurs/investors, with secondary users including property owners, real estate agents, and community/NGOs. Strategic partnerships include TUHF21 (affordable housing), Catapult Connected Places, Innovate UK, and Wits University's School of Architecture and Planning. The company is led by founder and CEO Yuriy Milevskiy, operates with 1-10 employees, and has disclosed only a single small funding round ($34,818 in August 2021).

OneCity competitors and assessment
Company assessmentDirect peers
- LandInsight: UK-based SaaS platform that helps property developers and planners identify, evaluate, and progress land opportunities through the UK planning system. Closest direct comparable to OneCity — same core workflow of finding, scoring, and triaging development land using spatial data, though focused on UK rather than South Africa.
- Reonomy: US property intelligence platform that aggregates ownership, debt, transaction, and zoning data to help commercial real estate professionals identify and analyze properties. Highly comparable in workflow (property search, site qualification, off-market identification) and in its model of layering proprietary scoring onto aggregated public/market data.
- HouseCanary: US residential real estate analytics platform providing valuations, market forecasts, and property intelligence to investors and developers. Comparable in its data-aggregation-plus-scoring model for residential development decisions and in serving small-to-mid property developers as a core customer segment.
- Local Logic: Location-intelligence platform providing walkability, amenity, and neighborhood-scoring data for real estate developers, brokers, and planners. Directly comparable to OneCity's Public Transport Accessibility Index and Local Amenities Index approach, though focused on North American and Canadian markets.
- UrbanFootprint: Urban planning and scenario-analysis SaaS used by cities, developers, and consultancies to model land-use, housing, and infrastructure scenarios. Comparable to OneCity at the urban-planning and policy-analysis layer, particularly in scoring and ranking sites by planning outcomes.
Broad incumbents
- SkyWatch: Satellite imagery and geospatial data platform that aggregates Earth-observation data for use cases including real estate, agriculture, and infrastructure. Comparable in the geospatial-data layer that OneCity builds on (e.g., Microsoft Building Footprints) but serves multiple industries rather than specializing in property development.
- Esri: Dominant GIS platform (ArcGIS) that provides the underlying mapping, spatial-analysis, and cadastral capabilities that OneCity's workflow depends on. A broad incumbent whose LandVision/ArcGIS Real Estate offering overlaps with OneCity's parcel-level analytics in larger markets; risk that it expands into emerging-market property intelligence.
Emerging players
- Geophy: AI-powered real estate analytics platform using machine learning on property and location data to produce automated valuations and asset insights. Comparable in its data-modeling approach to property and in serving institutional investors and developers, though at a different stage and in different geographies.
Regional players
- PropData: South African residential property data platform providing suburb-level market analytics, transaction history, and rental yields. Regional comparable in the same geography as OneCity, serving a similar property-investor audience but at suburb/market level rather than parcel-level development opportunity level.
- Lightstone: South African property data and analytics provider covering deeds registry, transaction history, valuations, and market intelligence. Most relevant regional comparable in the same geography as OneCity; operates as a broader data-and-insights incumbent rather than a land-development workflow tool.
