The brief
Erin Wester, Optimal Blue’s chief product officer, frames AI as a response to concrete lender problems—not a technology project pursued for its own sake.
FHA’s planned acceptance of VantageScore 4.0 and FICO Score 10T alongside Classic FICO gives lenders more options, but also adds implementation complexity across platforms.
Optimal Blue’s AI Labs connects customer needs with machine-learning capabilities, while emphasizing that lenders need understandable tools they can trust as AI evolves quickly.
The Virtual Economist pairs proprietary lock-volume data with a tightly controlled AI interface, offering market analysis without the unreliable agreeableness of general-purpose systems.
The conversation closes with Optimal Blue’s annual summit, where lenders, partners, and industry leaders compare practical experiences across the mortgage and capital-markets ecosystem.
