Sowell Management, an Arkansas-based registered investment advisor with $6.5 billion in assets under management and advisement, has launched Cache River Private Wealth to serve its growing sector of clients with net worth of $5 million and above.
Cache River Private Wealth will provide “family office lite” services to what founder Bill Sowell refers to as “high net worth plus” client households worth at least $5 million. The new division will coordinate services across investment management, tax and estate planning, as well as multi-generation family legacy and philanthropic initiatives to fill a “disconnect” that clients traditionally experienced when mixing advisors, tax and legal teams.
“Clients tended to have their attorneys on one hand, whether those were attorneys for their businesses or for estate planning, and then they had their accountants, and then they had financial advisors,” said Sowell. “And a lot of times they really didn't collaborate or coordinate to a large degree, and each were trying to accomplish certain things with a client that may or may not have been in concert with what the other part of the team was doing.”
Sowell founded his RIA in 2001 and now serves as chief strategy officer since Daryl Seaton succeeded him as CEO in January. Sowell says about 20 to 25 percent of Sowell Management’s current client base would meet the $5 million threshold for Cache River.
“For Cache River Private Wealth, we will specifically be recruiting advisors who have books that have at least 30 to 40 percent of their client base that fit that $5 million-plus bucket for clients,” said Sowell. “The reason that's important is it's a different conversation with clients that have net-worths of over $5 million versus clients that are smaller. Not that those are insignificant, but it is a different conversation.”
According to Sowell Management's latest Form ADV filing from March 2026, the firm employs around 100 advisor representatives and serves over 6,000 individual clients. Cache River Private Wealth follows several other new family office service units introduced by RIAs this year, including new practices from Farther, Wealthspire, and Summit Wealth Group.
Sowell Management remains majority-owned by Bill Sowell and his wife, Cindy, who is the firm’s executive vice president. At $6.5 billion in assets, the firm is on the larger side of RIAs operating without any outside investment, but Sowell said his firm could be open to private equity investment in the future.
“To say something like that's down the road, it's certainly possible,” said Bill Sowell. “At this point we've just focused on continuing to build and grow our firm. We've done a phenomenal job. We've got a great growth track record.”
