Our story
The questions came first. Then we built the data layer.
Val Buresch, CMB, spent years helping multi-billion-dollar lending businesses use data to understand markets, risk and communities. Greg Oliven, CTO, brought the engineering, cloud and analytics expertise to connect those sources at scale. Together, they built the data foundation behind Polygon Research.
Mortgage expertise
Val brings mortgage-banking judgment to questions of growth, fair lending, capital markets, performance and risk.
Data and technology
Greg architects the cloud, analytics and software that turn billions of records into usable mortgage intelligence.
Research and education
Our work as a data partner to NAHREP and other organizations informs sourced studies, interactive insights and courses that build analytical capacity.
Original methods
We build new ways to see the market
We develop transparent methods when the market needs a clearer measure. Each is documented, sourced and available in the same analytical environment our customers use.
PAI
We designed the Polygon Affordability Index, the first affordability index built on complete HMDA data and actual mortgage transactions.
Non-QM
We created an industry-first, transparent loan-level framework that classifies the full HMDA universe as QM, Non-QM or out of scope for market intelligence.
Source
