These key hires reinforce the company’s commitment to building best-in-class technology with a world-class team to support its next phase of growth.

With intuitive workflows, real-time reporting, and seamless PMS and POS integrations, it’s setting a new standard for hospitality accounting software.
“As we continue to grow, we’re focused on two things: investing in the right people and building the right products,” said JoAnn Kintzel, CEO of M3. “Klavs and Allison bring deep expertise in scaling organizations through periods of rapid growth, and their leadership will be instrumental in helping us expand both our platform and our team in a smart, sustainable way.”
“Blackstone is proud to support M3 through this pivotal growth phase,” said Ramzi Ramsey, Senior Managing Director at Blackstone. “With Klavs and Allison, M3 is expanding a leadership team equipped to accelerate innovation and unlock the next wave of growth in hospitality technology.”
