Kelli Sayres
Business Development

Kelli Sayres joined the Business Development team at Andrew Davidson & Co., Inc. in 2026.

Prior to joining AD&Co, Kelli spent more than two decades at PolyPaths, a fixed-income software provider specializing in mortgage and option-adjusted analytics.  Her first role there was to write the user manual, after which she worked her way up from client support associate to product manager to senior managing director of the company, guiding both day-to-day operations and long-term strategic vision.  Throughout the years, she has donned many hats, including financial modeling, quantitative and technical support, quality assurance testing, documentation, product design, model validation, sales, and marketing.  After PolyPaths was acquired by Numerix in 2023, Kelli served as Head of Product, developing a fixed-income roadmap and facilitating the integration of PolyPaths’ people, processes, and product into the larger firm.

Kelli holds an M.S. in Computational Finance from Carnegie Mellon University, along with a B.S. in Mathematics and a B.A. in History from Stanford University.
