An AI-enabled SaaS platform brought to production in 20 weeks

Cognisity is an AI-native PropTech company that connects permits, deeds, property data, market signals and satellite imagery to uncover missed taxable value across county property tax rolls. Its mission is to give local governments audit-ready, defensible data for accurate and accountable assessments. Cognisity partnered with Nimble.LA to build that product from the ground up, starting from a market thesis and no code.

Ownership transfers, new construction and major improvements all trigger tax reassessment, and legacy county systems cannot detect them across millions of property parcels. Assessors fall back on manual review, backlogs grow and taxable value goes unrecovered.

Cognisity had the market thesis and the county relationships. It needed a production-grade product fast, built on explainable AI that would hold up under public-sector audit and in front of senior California assessors.

• AI product development, concept to production
• Agentic development with risk-tiered delivery (ADLC)
• Detection models for ownership transfers, new construction and major improvements
• AI parcel prioritization and automated sales comps FMV worksheets
• Explainability, confidence scoring and statutory citation chains
• Data engineering at scale (medallion architecture, AWS Glue, Step Functions, Athena)
• Full-stack development and SOC 2-ready infrastructure (React, Node.js, Terraform, ECS)

Nimble.LA delivered a production-grade SaaS product in 20 weeks, with a proof of concept in the first ten and the full platform in the second ten. The system covers all 58 California counties and processes 500 million records, and Cognisity is now expanding into Oregon and Texas on the same foundation.
