Building the Tax Operating System – raises $3.6m to help you handle tax on a global scale

Managing taxes is notorious work. And if you are part of a tax team in a hyper growth startup that’s mid-international expansion, coordinating taxes across multiple geographies is no small feat. In the past, tax professionals have had only one viable option to manage taxes: hire a large, expensive firm to help you. This approach is cost-ineffective and merely serves as a stop-gap solution. In steps, a startup that empowers tax professionals to achieve sound tax governance with a “Tax Operating System” consisting of always up-to-date company data, regulatory data, visual analysis tools, and extensive team collaboration. has created a product that serves as the single source of truth for streamlining global tax operations and projects.

Some of the world’s most exciting companies are already using the platform via it’s subscription model and it’s truly disrupting how these teams handle their global tax operations and projects.

We are delighted to have the support of well-respected investors on our mission.

We’re thrilled to support as they expand their development team and accelerate the growth of their subscription tax management platform.
