Distinct shells carrying a filed role for this person — not every shell they have ever touched.
SEC-verified vehicles of the same sponsor, predating these roles and carrying none of them. The badge counts them; the figure beside this one does not.
Mergers closed across all 7 — these vehicles and the franchise's earlier ones together.
Announced but not closed, and still hunting — again over all 7.
No closed vehicle here has both a stored price and a filed trust value to score it against.

Steven Tannenbaum is an American investment professional and independent director who serves on the board of directors of Inflection Point Acquisition Corp. VI (NASDAQ: IPFX), a special purpose acquisition company that completed its initial public offering in March 2026, raising $253 million in gross proceeds. The SPAC, led by Chairman Michael Blitzer, CEO Kevin Shannon, and CFO Adam Saks, seeks a business combination with a North American or European business in disruptive growth sectors. Tannenbaum was appointed to the board upon the completion of the offering and serves alongside fellow independent directors William Denkin, Christopher Kellen, Carolyn Trabuco, and Jae-Hyun Park. The company is headquartered in Miami Beach, Florida, with its sponsor being Inflection Point Holdings VI LLC, and Cantor Fitzgerald & Co. served as sole book-running manager for the IPO with Academy Securities, Inc. as co-manager.
Since 1995, Tannenbaum has served as President of Greenwood Investments, Inc., a Boston-based firm that acts as the general partner of several investment partnerships focused on investments in public and private equities as well as the development of commercial real estate. He is also identified as the firm's founder and portfolio manager. Under his leadership, Greenwood Investments has built a multi-decade track record across asset classes, combining public market investing with private equity and real estate development. The firm is based in Boston, Massachusetts.
Tannenbaum began his career in 1984 as an energy futures contract trader and a member of the New York Mercantile Exchange. From 1987 to 1993, he managed physical oil and oil futures trading activities for Astroline Corporation and Tricon, USA, building deep expertise in commodities and energy markets during a formative period for energy derivatives trading. He earned a Bachelor of Science degree in Business Administration from the School of Management at Boston University in 1981. His extensive investment and managerial experience across public equities, private equity, real estate, and commodities trading formed the basis for his selection to the Inflection Point Acquisition Corp. VI board, where his broad market expertise is expected to support the SPAC's identification and evaluation of target businesses in disruptive growth sectors.
This record is keyed to SEC CIK 0001121942 — the identifier this person files under in their own name. Every vehicle above is a filing made under that CIK, so “the same person on two shells” is a fact about an SEC identifier rather than about a name that happens to match.
Roles are the strings the filings used, in the order they were filed. Nothing on this page ranks them, infers seniority, or offers a reason why any two of these names recur — a recurrence is a count, and the filings that produced it are linked beside every row. We also hold 35 institutional-holder rows on these vehicles, under 16 distinct name strings, and none of them is counted across vehicles: that table has no CIK column, and matching holders by name would merge firms that are not the same firm.
