2024 Rising Star: Tyler Lewris

Tyler Lewris

As Principal Data Scientist, Tyler Lewris has been a driving force behind Polly’s technology innovation. Lewris has successfully guided his team in building and scaling Polly’s sophisticated data architecture, which has provided the foundation for the company to bring new, purpose-built data applications and machine learning algorithms to market. Lewris’s passion for data democratization not only empowers Polly customers to make informed, data-driven decisions amid unpredictable market shifts, but pushes the boundaries of what is possible in data and analytics across the mortgage industry at large.

Lewris’s influence on Polly’s reputation as a data authority and changemaker in the mortgage capital markets space cannot be overstated. He joined the team at an inflection point, bringing an incredible amount of purpose and passion to his role and the application of cutting-edge data science and machine learning techniques. Data has always been core to the ethos of Polly, a standard that Tyler has not just upheld, but exceeded as the company continues to pioneer groundbreaking technologies that revolutionize and reshape the industry. 

Lewris was instrumental in Polly’s recent partnership expansion with HousingWire in February 2024, emphasizing both companies’ mutual commitment to increase the granularity, transparency and overall visibility of mortgage rate data. For the first time, HousingWire’s Mortgage Rates Center now includes actual, real-time rate data, uploaded on an hourly basis during market hours, and powered by Polly. It is because of Polly’s advanced data science and diverse datasets that this game-changer is even possible. Further, it is Polly’s architecture — directly impacted by Lewris’s contributions — that enables this level of quality and real-time data transparency.

What is the best piece of advice you have ever received?

The best advice I have ever received is rooted in the Japanese word ‘kaizen,’ which means continuous improvement. The idea that life is not about achieving perfection, but the relentless pursuit of progress. I believe this philosophy is the driving force between innovation and change, which is true across the mortgage industry, and absolutely evokes our mission and purpose at Polly. It is this belief in perpetual progress that makes me so grateful to collaborate with the high-caliber of talent at Polly, all of whom share this same mindset. It is what enables us to innovate and foster positive change and transformation across the industry, together.
