Founded in 2023, Maven Cost Segregation has rapidly grown to 50+ employees by doing one thing differently: delivering the most aggressive, IRS-compliant cost segregation studies in the industry. We're not just another tax firm — we're educators, investors, and engineers who understand depreciation from every angle.
"A maven is someone who is an expert or connoisseur in a particular field. The term implies not just knowledge, but also a willingness to share insights and guide others."
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.
