Deal Analyzer: AI-Powered CRE Deal Screening

As the lead product designer at Hypha, I’m designing an AI pre-screen that turns a broker’s raw deal package into a fast, trustworthy go/no-go for commercial real estate lenders, with every number cited back to its source.


The first-pass screen that took one to two days now takes minutes: 8X faster speed to decision, 97% error reduction, and 3X more source-linked analysis. Watching the underwriter run it, his reaction said it best: “I love it, and I love being able to capture more data.”

Through a relentless focus on conversion, trust, and usability, my design work has helped drive the platform to 3,000+ customers and $1M+ ARR.

My Design Principles

I'm always working to use design to build a more inclusive, empathetic world. My approach? Find the sweet spot where real user needs meet business goals through great collaboration. I loop in stakeholders and engineers early because good relationships make everything run more smoothly. I care deeply about user outcomes but also sweat the design details - because why choose between impact and craft?

Good design evokes trust

Always design with empathy

Communication is a pillar of successful design

How I Work

Step 1: Problem Definition & Strategic Alignment

Every project starts with research—I dive into industry trends, look for inspiration from adjacent markets that could help us stand out, review what we already know about our users, catalog existing pain points, and pull insights from any relevant data we've collected. Then I bring stakeholders together to ensure user needs align with business goals, which helps us prioritize what matters most and plan our next steps strategically.

Step 2: Design and Refine

Next, I translate our strategy into initial designs, making sure every screen balances business goals, user insights, and technical constraints. I schedule regular check-ins with stakeholders, engineers, and product managers to keep collaboration transparent and productive. We always talk through why we're making specific design decisions and where we can improve from the start—this creates a feedback loop that makes both the designs and our team understanding stronger.

Step 3: Iterate and Test

Handoff is never the finish line for me. Whether it's beta testing, A/B assessments, or user surveys, I'm always seeking ways to keep improving the product. I believe in learning continuously from users and iterating quickly to keep them engaged and satisfied. These insights directly fuel the next iteration, creating an ongoing cycle of product evolution.
