Meet our Global Leadership Team
Simon Paris
Chief Executive Officer
As CEO of Unit4, my priorities are to drive value, engagement and results for our customers, partners, employees and stakeholders, and through those priorities, drive long-term, sustainable SaaS growth. I am a passionate believer in the principle of "doing well by doing good", and a firm believer in how technology and software can have a positive impact on people’s lives.
Throughout my career, I have been a strong advocate for diversity and inclusion, developing young talent, and encouraging both a growth and a "customer 4 life" mindset.
Outside of work, I hold an MBA from INSEAD and a BA (Hons) from the European Business School. On a personal note, I have been fortunate to live in several countries, including Spain, France, and the United States. My wife and I are blessed with three children and together we like to travel and embrace different cultures and enjoy sport. I am also a "hopeless" fan of classic cars.
Jean de Villiers
Chief Customer Officer
The customer journey and experience is a critical component of a brand’s development and successful growth. I am a passionate believer in the power of combining well-motivated teams with agile methods to drive rapid and ongoing value for our customers and the stakeholders that they represent. Being a part of their journey and success is fundamental to our future growth and success. To that end, I am focused on building holistic, integrated, expert and agile teams to enable amazing customer journeys.
When not engaged with our customers and teams, I am a keen surfer, mountain-biker and rugby fan.
Claus Jepsen
Chief Technology Officer
I’ve been fascinated by technology since age 14: from my first Tandy TRS Model 1, through to developing cloud-based, super-scalable solutions and bringing innovative technologies such as AI, chatbots, and predictive analytics to ERP. We really can now have better, non-invasive and pervasive solutions — to improve People Experience and help us focus on what we truly love.
My spare time is spent with family and friends. I can often be found road biking to stay in shape, and I love experiencing different cultures through traveling.
Jennifer Sherman
Chief Product Officer
I am on a mission to improve the experience of work for as many people on this planet as I can. For me that means delivering tools and technology that enable people to make smarter, more effective decisions and to be as efficient as possible with our most valuable resource: time. It also means building and supporting great teams of people, so that they can have successful and productive chapters of their career while delivering great solutions to their clients and communities. I am an advocate for diversity of people, thoughts and ideas as we all work together to move technology and work forward.
Outside of work, my passion for lifelong learning drives me to be on the constant lookout for new classes to take; the more esoteric the better. From glass blowing to jam making, from Arduino programming to storytelling, if someone offers me a course on a new skill, I will probably sign up.
I have a BS and MS from Stanford University in Industrial Engineering and Engineering Management. I am a TEDx speaker, a certified judge with the Kansas City Barbeque Society, and I am currently two weeks away from my bread baking diploma.
Johan Reventberg
Chief Revenue Officer
I’m passionate about making a real difference for our customers and people, with our innovative and industry-leading technology. I believe my main strength as a leader is to help sales-oriented teams and individuals discover and achieve their potential and, in doing so, helping to realize expected business, as well as personal outcomes. This is why I am at Unit4 and I’m really enjoying the ride.
I believe that the principles of empowerment, transparency and focus generate trust and results, that true diversity builds winning teams and that competitiveness is a core foundation for all businesses.
Most of my passions outside of work are sport related and can be experienced on or near a mountain, in both the winter and summer time, and preferably with the whole family. Life should be enjoyed, and practicing the ‘good-life’ outside of work with family and friends all over the world is a top priority for me.
Matthew Bagley
Chief Financial Officer
For me, the most important asset of a company is its people, and I am passionate about nurturing and developing talent – not just in my teams but across the whole company. I enjoy building high-performing finance teams that are true business partners to the company’s senior leaders and are critical to efficiently scaling high-growth technology companies.
When I’m not working, I love to spend time with my family, travelling, enjoying good food, and I’m also a keen golfer.
Tania Garrett
Chief People Officer
I believe the key to business success is a shared cause and purpose, genuine leaders and world class people. Throughout my career I’ve had the great fortune to be part of businesses where I’ve been able to help shape each of these elements. I’m passionate about helping people achieve a shared sense of success in their own development and business performance whilst driving engagement and loyalty through fully aligned business and people strategies.
When not working, my husband and I enjoy spending quality time with family and friends at the beautiful south west coast of the UK. We love to travel enjoying sun, snow, cities and mountains in equal measure.
Michelle Eisenberg
General Counsel
I am passionate about legal services driving business success. Whether it’s through advising on contracts, intellectual property, SaaS transformation, compliance or privacy, the legal function is well placed to provide input on strategy and can help connect the dots, to see the path ahead more clearly. I’ve been fortunate, throughout my career, to build and foster effective global legal teams in fast-paced technology companies and believe that both internal and external interactions with Legal should always be a pleasure.
Unit4 has a powerful combination: transformational technology that focuses on improving our customers’ experience; and our own people, who care deeply about the same mission. I am excited to be part of a company that aims to make a real difference for our people and communities.
I take an active interest in supporting diversity and inclusion initiatives; I enjoy long walks with my dogs and spending quality time with my family and friends.
