AMBLER, PA — Lansing Street Advisors LLC, an Ambler-based investment adviser and family office, rose six positions to No. 17 on the Philadelphia Business Journal’s 2026 Fast 50 list, marking its second consecutive appearance among the region’s fastest-growing privately owned companies.
The firm advanced from No. 23 in 2025, according to rankings released October 20. The annual list evaluates independently owned companies headquartered in Greater Philadelphia based on average revenue growth over three years.
Lansing Street Advisors, an investment adviser registered with the Securities and Exchange Commission, provides financial services to families. The firm is led by founder and Chief Executive Officer Matt Topley.
The 2026 rankings reflect revenue performance from 2023 through 2025. Eligible companies were required to generate at least $750,000 in revenue, demonstrate consistent growth during that period and maintain independent ownership and a local headquarters.
The Philadelphia Business Journal and accounting firm CLA reviewed companies for eligibility before determining the rankings.
“We’re proud to be building our firm right here in the Philadelphia region,” Topley stated.
The rankings were presented at the Business Journal’s Fast 50 awards event on October 20, which representatives of Lansing Street Advisors attended.
