About Us

For over 10 years, Chargify has enabled thousands of businesses to manage the recurring revenue lifecycle. Our vision is to become recognized by our customers as the indispensable system for running a subscription business.

Our Story

In 2009, the founders of Grasshopper saw the need for a service to help SaaS businesses manage their recurring revenue customers. Chargify started out as a team within Grasshopper — focused on the core needs of recurring billing.

In 2011, Chargify received an investment from Mark Cuban, owner of the Dallas Mavericks and one of the investors on the TV show “Shark Tank.” Mark’s investment allowed Chargify to form as a separate company from Grasshopper and achieve profitability in 2012.

Over the past decade, Chargify has expanded its offerings to address the complexities of the entire subscription lifecycle: Recurring Billing. Subscription Management. Revenue Retention. Business Analytics. Revenue Operations.

Chargify Shield

In 2016, Chargify was acquired by Scaleworks, a SaaS holding company. Scaleworks understood how critical billing and revenue management is for modern businesses, how other toolsets are not sufficient for the subscription business model, and how Chargify solved pain points across their portfolio of companies.

Chargify combines great technology, subscription expertise, and a customer service ethos to solve real-world problems and is committed to becoming the operating system for your subscription business.
