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

The data needed to make confident property decisions was scattered across thousands of county records, permit offices, contractor registries, and assessor databases. None of it was connected, much of it was dirty or unreliable, and almost none of it was available through an API.As a result, critical decisions were being made without the full picture.
  • 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.

  1. Founded in Menlo Park, CA

    Started with the core vision of normalizing municipal building permit logs across the United States.

  2. First Enterprise Partnerships

    Delivered customized property insights directly into top tier real estate and loan origination platforms.

  3. PICO™ Launched

    The first national property condition score, transforming unclassified historical permits into a dynamic property baseline.

  4. REACH Program Integration

    Backed by REACH, the strategic technology accelerator program of the National Association of Realtors® (NAR).

  5. Knowledge Graph Scale

    800M+ permits across 110M+ properties. Active production deployments at SoFi, US Bank, Opteon, and Realtor.com.

  6. AI-Native Property Intelligence

    Launched Kukun Model Context Protocol (MCP) Server for real-time generative agent data integrations.

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.
