Schipul | A Little Company Culture History

Schipul & Tendenci Tendenci's story is intertwined with Schipul - The Web Marketing Company. In 1997, Ed Schipul quit his full-time job as a software consultant for a large petroleum corporation and started his own web marketing company. Armed with a Political Science degree from Texas A&M, a background in programming, and a fascination with social trends, Ed and his wife Rachel Schipul - started building websites that helped people communicate. Years of custom requests from his nonprofit clients led to the initial construction of Tendenci, a platform of tools that most organizations need, or could use, to increase both their communication and revenue streams. Read more about Ed Schipul.

In 2004, Tendenci received its official name and was sold by Schipul to clients around the world, filling a need for affordable membership management and association website marketing software. Other membership software applications were either too costly, too technical, or not robust enough to manage the complex transactions for membership management, email marketing, event management, and donations management. Tendenci was developed to solve these problems and provide a simpler, better, and cheaper solution.

In 2012, Tendenci was released as an open-source AMS SaaS product to extend its reach even further, allowing developers around the world the ability to download and build on the Tendenci platform. In November 2013, Schipul officially changed its name to Tendenci to focus on the expansion of the software and the developer community. No clients were harmed in the making of this move - Schipul remains a professional service division of Tendenci, assisting nonprofits with marketing design and effective website strategies.
