Our Story

From startup to industry leader in 3 years.

Maven Cost Segregation was founded in 2023 by Sean Graham, a registered CPA and active real estate investor who saw a gap in the market: most cost segregation firms were either too conservative (leaving money on the table) or too sloppy (exposing clients to audit risk). Sean built Maven on a different premise, aggressive and compliant aren't mutually exclusive.

By combining CPA-level tax knowledge with detailed engineering methodology, Maven quickly earned a reputation for delivering studies that maximize deductions while remaining fully defensible under IRS scrutiny. Word spread fast through the real estate investing community, from BiggerPockets forums to CPA referral networks.

In just three years, Maven has grown from a small team in Detroit to over 50 employees across 5 offices nationwide, delivering 5,000+ studies and identifying more than $750 million in accelerated depreciation for our clients. With a collective 100+ years of cost segregation experience on our team, our 100+ CPA partners trust us because we speak their language, and because our studies hold up.

"I've known Sean for a while now, and when it came time to do a cost segregation study, there was no question I'd turn to him and his team at Maven. They were incredibly knowledgeable and walked me through the process step by step, helping me understand the real value of doing a cost seg."

"It was an absolute pleasure working with this company. They provided quick, impressive results in a timely manner. Kayleigh was incredibly knowledgeable and communicative.

J
James McDonald

"We had a great cost seg experience with Sean and team. They saved us honestly. We'd been under the false impression for years that a cost seg wasn't worthwhile for our STR given its high land value.
