Zumasys is a software company headquartered in the beach town of San Clemente, California. With team members spread across North America, we specialize in providing application software solutions built on Pick MultiValue technology.

  • We assist our customers in furthering the development of their business-critical applications.
  • We modernize applications and extend their functionality with our rich history in databases, connectivity tools and cloud computing.
  • We acquire Independent Software Vendors (ISVs) and help them move to an on-demand hosted delivery model i.e. Software-as-a-Service (SaaS).

Beyond the amazing products, it is our people who make the difference.

Zumasys team members are obsessed with efficiency, and we love helping customers use technology to unlock the full potential in their businesses. We design the world’s most adaptable software for a variety of vertical markets including distribution, manufacturing, retail, and higher education. We draw upon our rich history as former owners of databases, connectivity, and productivity tools to modernize applications and unlock their full potential. Zumasys also employs a services team of business analysts and developers who help customers enhance their critical business applications.


In September 2000, Paul Giobbi co-founded Zumasys with his late business partner Joe Cupp. Initially Zumasys began as a hardware reseller but quickly grew into a vibrant, fast-growth technology company with nearly $30M in revenue.

In the early 2000s, Zumasys became a pioneer in cloud computing, offering a service that allowed companies to move their business-critical applications to a hardened data center and to run on a 100% virtual server platform.

15 years later the company expanded into database software solutions with its acquisitions of AccuTerm, jBASE and OpenQM.

More recently, Zumasys began acquiring Independent Software Vendors (ISVs), helping them enhance their vertical market applications and moving them to a Software-as-a-Service (SaaS) business model.

Zumasys ultimately sold its cloud and IT infrastructure business to NexusTek in 2018 and sold its databases and tools to Rocket Software in 2021.

Today Zumasys focuses exclusively on developing vertical application software and accounting systems. We protect the decades of investment that our customers have in their applications and we help to prepare them for the future.

Even though technology changes, our mission remains the same.

We Are Powered By Purpose

Our vision is to be the most trusted and respected partner in the communities we serve. By sharing the power of purpose, we inspire people to pursue “happyness” and redefine how businesses contribute to society. Elevating the needs of our stakeholders (not just our shareholders), has facilitated our consistent growth and wide recognition of our unique cultural programs.

Our workforce is almost completely virtual. Our developers are self-regulated and have incentives to continually innovate and delight our clients through the excellent software solutions that we deliver. We hire and incent our people exceptionally well, allowing us to set the direction for our team members and then stay out of their way. We entrust people to operate with independence and make common sense decisions.

Through our Happyness is a Choice program, we’ve given away more than $1M to 300 nonprofit organizations and individuals globally.

We are founders, entrepreneurs, executives, and empowered people who act like owners. We embrace open-book financials and autonomy. We are a family of creative and unique professionals who take care of each other with our award-winning corporate benefits and incentives.
