Having enjoyed two notable entrepreneurial successes by the age of 43 (The Harborside Financial Center and Emmes & Company)  Michael Sonnenfeldt created a unique peer-to-peer learning group for entrepreneurs, like himself, who had recently experienced liquidity events and were eager to learn best practices from other similarly successful entrepreneurs, for preserving wealth, while also exploring issues of relevance, legacy, family, philanthropy, and the big “What’s Next.”

What began as a single group of six entrepreneurs in New York City grew into TIGER 21, the premier peer-to-peer learning network for high-net-worth wealth creators. TIGER 21 has over 1100 members participating in over 100 groups across the United States, Canada, and Europe, and is expanding into Asia and the Middle East.

Collectively, TIGER 21 members manage personal investments of over $140 billion.

The ranks of TIGER 21 Membership are filled with some of the world’s most successful entrepreneurs.  The target market for TIGER 21 is Members with between $20 million and $1 billion of investible assets. At a numeric average of $120 million per Member, the community represents a level of accomplishment roughly equal to 1 in 10,000, which is roughly equal to the rarefied air occupied by major league football, basketball and baseball players.

In 2019, the private equity firm Education Growth Partners acquired a significant minority stake to enhance member offerings and support TIGER 21’s expansion around the world. Sonnenfeldt continues to serve as Founder and Chairman and remains the majority equity holder. In 2020, TIGER 21 was recognized for its industry thought leadership by Family Wealth Report at its Seventh Annual Awards ceremony.
