About Kukun
The Property Knowledge Graph for Real Estate AI
Every property has a history: permits, improvements, and changes in condition. For too long, financial decisions overlooked it. Kukun has spent twelve years building the graph that connects it all.
The Origin
Founded on a Frustrating Insight
2014
Valuation Misalignment
Banks valued houses without knowing about $60K home remodels, leading to inaccurate valuations.
Underwriting Risk
Insurance carriers assessed risk without seeing unpermitted additions that could affect safety and premiums.
Speculative Portfolio Decisions
Investors acquired portfolios without a single objective property condition score to benchmark real risk.

Property has a history. Kukun built the infrastructure to make that history useful.
The only connected, address-level record developed for 12+ years, queryable in a single API call.
Twelve Years of Building
The Graph Took Time Because Property Data is Hard
Building a true Nationwide Property Knowledge Graph requires continuous municipal harvesting, deep geographic normalizations, and rigorous auditable pipelines. Here is our journey.

How Kukun Operates
A Small Team. A Very Large Graph
Kukun remains structured to build things of lasting scale. The team focuses entirely on data-engineering, geographic normalizations, and delivery infrastructure.
Infrastructure Thinking
We don't build features or portals; we construct the underlying data plumbing for enterprise real estate platforms.
Accuracy Over Volume
Dirty permit logs are useless. We clean and de-duplicate every record through a multi-pass validation pipeline.
Connected, Not Collected
We tie municipal building records directly to assessor files, creating a unified property-level history.
Integrations In Days
Our unified APIs and comprehensive documentation mean developers go from raw keys to production in days.
The Graph is Ready When You Are
API keys issued same day. Enterprise contracts close in days, not months.
