John Cimba takes the helm as CEO to continue the company’s mission to redefine the payments experience

ORLANDO, Fla. – February 9, 2026 Stax Payments, a leading payment technology provider, has appointed John Cimba as Chief Executive Officer of the company, succeeding outgoing CEO Paulette Rowe.

Cimba currently serves as an operating partner with Stax’s control investor, Greater Sum Ventures, guiding growth and operational strategies across its software portfolio. Before that, he served as CEO of PropertyTek, a software and integrated payments platform for the property management industry. Previously, Cimba led full-service marketing agency GLC from 2007 until its successful sale to private equity.

Cimba will focus on leveraging Stax’s momentum as a newly minted end-to-end processor and will drive the company’s mission to eliminate transactional friction between businesses and the customers they serve.

Cimba will lead alongside Stax’s executive leadership team, including Chief Administration Officer David Winters, Chief Financial Officer Kevin Wall, Chief Technology Officer Mark Sundt, Chief Transformation Officer Adam Gray, and Chief Marketing and Customer Success Officer Jenn Reichenbacher, among others.

“John is a collaborative and results-focused leader who has scaled multiple equity-backed platforms. We’re confident in his leadership to build on Stax’s momentum in a competitive fintech environment,” said Ross Croley, founder and CEO of Greater Sum Ventures, a growth equity firm whose portfolio of companies collectively process more than $60 billion in payments annually. “We’re also grateful to Paulette for the significant achievements during her tenure, notably the increased autonomy, agility, and innovation at Stax.”

Under Rowe’s leadership, Stax has expanded its multi-channel offerings and completed a multi- year evolution to become an end-to-end processor. Built on industry acquisitions of APPS and BlockChyp, Stax’s new capabilities unify the payments process, from origination through API and gateway to tokenization, clearing, and settlement. This single-source solution provides a direct connection to all major U.S. card networks and brings the full transaction flow in house, enabling a level of data orchestration and control difficult to achieve when relying on separate third-party relationships.

Cimba added, “The remarkable team at Stax has built impressive technology that stands out in the dynamic world of fintech. This is an exciting time in the company’s history as it integrates the entire payments lifecycle and delivers even greater value to its customers and partners.”
