Wealthbox eyes next growth phase with $200M Sixth Street investment

Wealthbox, the top-rated CRM platform focused on the advisor market, is poised to improve its standing in the market with a monster round of private equity financing.

The fintech firm has secured a $200 million majority investment from Sixth Street Growth, the growth investing arm of Sixth Street, to support its continued expansion and product development.

According to a statement from Sixth Street, Wealthbox plans to use the strategic financing to accelerate the development of its CRM technology, incorporate new AI features, deepen enterprise functionality, and broaden its integration with other components of the advisor tech stack.

“This partnership with Sixth Street is a defining moment for Wealthbox,” said John Rourke, chief executive and co-founder of Wealthbox. “We’ve spent years building a modern, elegant CRM that advisors truly enjoy using. With Sixth Street’s backing, the new funding will allow us to move faster than ever to extend our leadership in the market and deliver even more value to advisory firms of all sizes.”

The $200 million infusion from Sixth Street represents a strong vote of confidence, standing an order of magnitude above other strategic financing deals announced in the fintech space over the past year, including the $20 million Series A round for Jump in February, the $15 million financing announced by Boosted.ai in November, and the $35 million funding round for Facet in October.

Sixth Street's investment comes as Wealthbox continues to gain momentum in the advisor CRM category. The 2025 T3 Inside Information software survey found Wealthbox ranks second overall among advisor CRMs, and is emerging as the top-of-mind choice for firms looking to switch platforms.

Survey data showed that nearly 14 percent of Redtail users are considering a move to Wealthbox, compared to just 4 percent of Wealthbox users who are eyeing Redtail. The survey also found Wealthbox to be more popular among less-experienced advisors and smaller firms, holding 25 percent of market share among advisors with five years or less in the industry.

Although Wealthbox’s user base currently skews toward smaller RIAs, the company has signaled its intent to move further upmarket. The new capital is expected to support that trajectory, along with the rollout of new artificial intelligence features aimed at improving advisor productivity and firm-wide efficiency.

“Wealthbox’s platform combines user-friendly simplicity with powerful capabilities, underpinned by a deep commitment to customer satisfaction, and we believe that it offers a valuable, advisor-centric CRM solution for the wealth management channel,” said Michael McGinn, partner at Sixth Street and co-head of Sixth Street Growth.

Wealthbox is owned by Starburst Labs and is used by thousands of RIAs and advisory firms to manage client relationships, streamline operations, and support business growth. The platform is known for its intuitive user experience, modern interface, and integration with other industry tools.

Sixth Street has invested more than $10 billion across over 70 technology companies through its Growth franchise.
