PayIt is a fast-growing GovTech company on a mission to bring governments and people closer together through our award-winning, SaaS platform. 


When PayIt started, it was difficult (or just plain impossible) to renew a Driver’s License or pay a court ticket in a mobile, quick, or convenient way. PayIt, along with our award-winning government partners, has made processes like going to the DMV or to a county courthouse, one that you can do right from your smartphone or computer. Since then, PayIt has been building an entire business toolkit for local and state government agencies while simplifying doing business with government agencies by consolidating hundreds of services and payments into one connected experience for citizens. Meanwhile, through our secure cloud-based platform, we have reduced friction for the everyday citizen, making digital government services accessible, equitable, and efficient.


We recently received a large growth investment in August 2022 and are well funded, we have picked up awards from Forbes, FAST Design (alongside McDonald’s and Nike), our CEO has won EY Entrepreneur of the Year award, and we have been recognized as a leader in our industry as a GovTech 100 the past six years in a row.
