To whom it may concern:
I have known Jen Mack personally and professionally for nearly a decade. We have attended
conferences, meetings, strategy sessions and social business events on 5 continents as friends, business
acquaintances, business partners, and with her as an executive leader at G2. During that time, I have
had the opportunity to observe, interact, and partner with Jen in nearly every conceivable business
situation.
It is my view as one of the Founding Partners at G2, that Jen has been unfailingly professional in all her
interactions and has proven time and again her ability to uniquely build strong industry
relationships. Such executive relationship management is key to any business and is one of the leading
factors that caused us to recruit Jen at G2. It is also the area we will miss her expertise the most.
Moreover, Jen has a proven capability to tackle tough problems with great success. G2 had a ringside
seat during her time at MasterCard as she built the PCI360 program from the ground up, to educate
acquirers, ISOs, and even merchants globally about the rules, risk reduction, and benefits of PCI DSS
compliance. My perspective is that her strategic vision helped accelerate the adoption of PCI globally
and helped educate thousands of industry participants who would have likely been otherwise
uninformed. This innovative approach continues to be successful today.
Separately, when Jen came to G2, one of her first tasks was to examine the growth and success of one
of our biggest service deliverables, PCI2. This service was designed to identify service providers working
with merchants globally. Jen tackled an entire re-branding and technology acceleration project with
energy and zeal. The product was successfully rebranded and new technology improvements suggested
by Jen have radically improved the program deliverables and profitability.
It is hard to summarize the qualities of a seasoned executive I have known for 10 years in a few
paragraphs. I can only do so by recommending Jen for any executive position that can successfully
leverage her unique executive relationship skills, proven problem solving, and exceptional
professionalism. I would be happy to take further inquiries at any time.
