Background
Mark Stierman is a real estate investment banker with roughly three decades of experience in real estate mergers and acquisitions, recapitalizations, valuations, and capital raising. He spent nearly 28 years at Robert A. Stanger & Company, Inc. — the Shrewsbury, New Jersey independent investment bank known for valuation and advisory work in real estate, private equity, and alternative investments — where he rose to Executive Managing Director. At Stanger, his work included financial advisory on mergers, acquisitions, and recapitalizations, along with strategic-planning and product-structuring consulting and valuation of real estate portfolios, real estate–related securities, debt instruments, and operating companies.
In April 2023, Piper Sandler & Co. announced that it had hired Stierman, together with Peter Fish, as Managing Directors on its Real Estate Investment Banking team within the Financial Services Group. Based in Piper Sandler's New York office, Stierman focuses on advisory and capital-raising assignments for private real estate operators and real estate fund sponsors.
Stierman holds a Bachelor of Business Administration from Texas A&M University and a Master of Business Administration in finance from Rutgers University.
Investment Thesis & Focus
- Operates as an investment banker / financial advisor rather than a principal angel investor, per all located sources.
- Focus area: advisory and capital-raising for private real estate operators and real estate fund sponsors (his stated mandate at Piper Sandler).
- Deep expertise in real estate M&A, recapitalizations, product structuring, and valuation of real estate portfolios, real estate securities, debt instruments, and operating companies (from his Stanger tenure).
- Sector concentration is real estate and alternative investments, not early-stage technology or seed-stage startups.
Notable Investments
- No verified startup/venture portfolio companies were found. Stierman's documented deal work is advisory (sell-side/buy-side M&A, recapitalizations, capital raises) in real estate, executed on behalf of clients at Robert A. Stanger & Co. and now Piper Sandler, rather than personal angel investments. Specific named transactions were not publicly attributed to him in the sources reviewed.
