The investment is expected to accelerate Franklin, TN-based HubSync’s product roadmap and customer service, as well as enable continued growth and innovation.

“This investment is a testament to the strength of our platform and team,” he added. “We look forward to partnering with Thoma Bravo to drive further growth and transformation of the tax and accounting landscape.”
