Executive biography

Bill Lyons, Founder, President & CEO

Founder-led leadership across specialized mortgage lending, real estate finance, mortgage technology, company growth, and customer experience.

Bill Lyons is the Founder, President and CEO of Griffin Funding, a direct-to-consumer mortgage lender founded in 2013. He leads Griffin Funding's strategy across mortgage lending, real estate finance, technology, growth, and customer experience, with a particular focus on serving self-employed borrowers, real estate investors, veterans, homeowners, and other clients whose financial profiles may call for specialized mortgage solutions.

Under Bill's leadership, Griffin Funding has built a lending platform spanning conventional and government mortgages as well as specialized Non-QM programs, including DSCR loans for real estate investors, Bank Statement loans for self-employed borrowers, Home Equity financing, and VA loans. His approach combines product breadth, direct-to-consumer distribution, disciplined mortgage operations, and technology-enabled decision support with experienced human judgment.

Executive leadership and documented recognition

HousingWire named Bill a Vanguard in 2020 and again in 2022, recognizing his executive leadership across mortgage, real estate, and financial technology. During his tenure, Griffin Funding has appeared on the Inc. 5000 six times—in 2017, 2018, 2021, 2022, 2023, and 2026. Griffin's 2017 appearance reached No. 83 nationally after 4,473% three-year growth, and HousingWire identified the company as the fastest-growing mortgage-finance company on that year's Inc. list.

Griffin Funding has also received Inc. Best in Business honors in Financial Services, Inc. Best Workplaces recognition, an Inc. Regionals Pacific ranking, and a 2026 HousingWire Tech100 honor for LIA, Griffin's mortgage intelligence and decision-support platform. Experience.com's 2025 Top Performers also recognized Griffin among the Top 10 Mortgage Companies in the Small Division for customer satisfaction.

Mortgage technology, media, and entrepreneurship

Bill's perspective on mortgage lending, entrepreneurship, real estate finance, and company building has been featured across major business and housing-industry outlets. He has been profiled by a Forbes contributor, interviewed by HousingWire, quoted by WSJ Buy Side on mortgage options for self-employed borrowers, and has contributed commentary through Forbes Councils.

Earlier in his career, Bill founded Revestor, a real-estate technology company designed to help investors evaluate properties using cash-flow and investment-performance data, and appeared on ABC's Shark Tank. That background in real-estate technology and entrepreneurship informs Griffin Funding's continuing investment in mortgage technology and specialized lending.

Professional background and leadership philosophy

Bill is a licensed real estate broker and a member of the Mortgage Bankers Association, Forbes Real Estate Council, and Entrepreneurs' Organization. Griffin Funding's public biography also notes his studies at Arizona State University and Anthony Robbins' Mastery University. His operating philosophy is centered on building a durable mortgage company that combines flexible lending options, accountable teams, efficient technology, and a high-touch borrower experience.

As CEO, Bill's role is ultimately to align Griffin Funding's people, products, technology, and capital around a clear objective: helping borrowers and real estate investors identify financing that fits their circumstances while maintaining the execution standards required of a modern direct mortgage lender.
