A commitment to our clients

NCCEH Ipad ImageDecisions about the software and how to evolve the project all rotate around what would benefit our clients the most. What will help them reach their goals, expand their programs or better communicate?

Tendenci was built from years of listening to our clients - and we've never stopped paying attention!

One of the core company books is Good to Great and the Social Sectors. We believe that to provide the best service to our clients, we must understand how nonprofits work. That's why our employees sit on multiple NPO boards, from education to the arts.

A little company history

Schipul - The Web Marketing CompanyTendenci's story is intertwined with Schipul - The Web Marketing Company. In 1997, Ed Schipul quit his fulltime 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 web sites 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 as a professional service division of Tendenci, assisting nonprofits with marketing design and effective web site strategies.
