Jim Serafin

CEO

Jim is responsible for operational oversight across all divisions of Cartesian. He also directly leads all North American operations.

Jim’s information technology services career began in the 1980’s as a senior technology engineer at EDS, servicing large systems development efforts at large telecom clients. After spending 9 years progressing from senior technology leadership into account executive leadership at EDS, Jim founded the technology services firm Emerald Solutions in 1997 and grew it to over 100 employees in 3 years before selling the business (2001) to the private equity backed technology firm SBI Holdings, Inc. He integrated the firm into SBI Holdings and was CEO and President of the Corporate Performance Management and Integrated Marketing divisions of the company. While there, Jim led the acquisition and integration of over 20 public and private firms into the enterprise and built the eventual business into a $200M entity from 2001 to 2006. In 2007, Jim sold the Corporate Performance Management division to another services firm, Enterpulse, and was named President and Chief Operating Officer from 2006-2008. He was responsible for sales, marketing, and operations across the US. The firm concentrated on delivering large-scale CRM initiatives, large data stores programs, and ERP solutions across multiple industries, and was a key strategic partner for such firms as Oracle and Interwoven in these domain spaces. Growth was achieved across a diverse F1000 suite of businesses concentrated in the US. The firm was sold to an offshore technology firm looking to establish a US-based presence in 2008.

After leaving Enterpulse, Jim founded and operated multiple diverse enterprises, leveraging his technology background expertise and M&A experience. In 2008, Jim founded a fuels distribution business concentrated on the East Coast and focused on “wet” and “dry” delivery services. Simultaneously, he founded and operated a building maintenance and electrical services firm providing life cycle build, repair, and maintenance services for the imbedded infrastructure of large multi-state companies. The company services diverse clients such as Ahold USA (Giant Markets Division), Weiss Markets,  Raymour&Flanigan (commercial real estate and retail divisions), and Sheetz MiniMarkets (over 500 gas stations located in 5 states). After exiting his partnership in these firms in 2016 to join Cartesian, the companies continue to operate and grow as independent private firms.

Jim graduated with Honors from Villanova University (Mathematics) and Lehigh University (Mathematics).

Consultant

I decided to work at Cartesian because of the work culture that is offered. Everyone on the team has been very supportive of each other from helping bring newer hires up to speed on the work being done to lending a hand on a project they may have had experience with previously. It has created a collaborative environment that allows everyone to grow their skills and learn.
