Meet the stewards
of the Stone Three

Stone Three is led by a group of passionate individuals, who ensure staff fulfillment and client satisfaction at all times.


Eugene Jansen


Chief Executive Officer

Eugene has been part of Stone Three since 2009. He is responsible for turning our vision and strategy into reality, employing his keen commercial focus and belief that people should be allowed to focus on what they are passionate about and good at.

He believes that building sustainable partnerships, working with awesome people, being flexible and having fun along the way are all vital to success.

Francois Swanepoel

  SwaneChief Technology Officer

Francois was a co-founder of Stone Three (originally called Stone Three Signal Processing). It was his Masters project, a particle size analyser using acoustic technology, that started it all back in 2000.

Francois is all about the technology. He loves nothing more than working with his team to solve a complex software challenge. And if something new has hit the market, Francois will be one of the first to know about it.

His motto is: “Always delight your clients – it’s the only way you’ll stay in business.”

In her role as resident coach, it’s Debbie’s job to encourage the development of our people and ensure that  they’re happy, productive and growing – hence her informal title: ‘Chief Happiness Officer’.

Debbie has always had a heart for helping people. Before joining Stone Three she studied radiography, specialising in Ultrasonography. She joined the team in 2001 as a part-time financial administrator. Over the years, her love for the company and its people has grown exponentially, to the point where she now heads up Team Dynamics.

Dirk Wagener

DirkBusiness Development Manager

Dirk is our “man on the ground”. He works closely with our new clients during the initial phases of the relationship, building trust and helping them define their requirements through workshops and brainstorming sessions. He is also an engineer and supports the development team, acting as the go-to-guy for technical operations.

Always willing to roll up his sleeves and get stuck in, Dirk is also deeply involved in Stone Three’s marketing and business development activities. His philosophy is: “Do business from the heart and the rest will follow.”
