Executive Team

Gareth Burton
I joined Orbus as CEO in September 2022 following an extensive career within international technology companies and SaaS businesses. I previously held the position of CEO at ThinkProject, as well as other senior roles at Motorola and BT. I have also had a number of board-level IT positions within the oil and gas, mining and construction sectors, and have 10 years experience as a CIO, working for companies such as Laing O'Rourke and Baker Hughes.
Throughout my career, I have led large digital transformation programs and will use this experience to lead Orbus Software into the next stage of its growth. I passionately believe that there is a huge opportunity for companies to digitalise today, but they need the visibility to truly transform. That is where Orbus Software comes in.

Paddy Deller
I joined Orbus Software in 2023 as the next step in an exciting and varied finance career that has taken me all over the world. From international postings in Bermuda, to growing ActiveOps business by 350%, my journey has given me experience in a broad range of finance disciplines that I am excited to lean on at Orbus.
As CFO of any business, you have the opportunity to work with the finance team to deliver a solid and efficient financial operation that supports many different areas of the business. I have experienced some of the rewards and challenges of working in a similar-sized SaaS software business, so I hope to bring additional context to the Orbus journey.
I am thrilled to join such an energetic and enthusiastic team of people. During my career so far, it has always been my colleagues that have had the biggest impact on my work, and I am excited to join a great team with big ambition.
Outside work, you’ll probably find me playing tennis or trying my hand on the golf course. Meeting up with friends and enjoying a good meal at the local pub also always goes down well!

Oliver Hecquer
I first joined Orbus Software in 2016, and have been working as Chief Customer Officer since early 2021.
My career to date has been a fantastic adventure.At various points you would have found me manning the grill station at a posh NYC restaurant, calling real estate agents across Australia to develop the sales capability at a budding telecom, unpicking tuition payments-gone-wrong for international students at a now billion-dollar start-up, consulting for Accenture, or, since 2016, building Orbus’ market-leading customer teams across Professional Services, Customer Success, Support and Customer Ops.
I've learned a lot on my journey so far and am passionate about helping our customers and internalteams cut through “noise” to deliver real value, both for themselves and their organizations, while having plenty of fun along the way.

I joined Orbus Software as Global SVP of People in September 2024, bringing over 15 years of experience in strategic HR leadership across high-growth startups, global enterprises, and SaaS businesses. My focus is on aligning people strategy with business outcomes by building the structures and culture that help companies scale with clarity, purpose, and resilience.
Prior to Orbus, I ran a leadership and HR advisory practice and worked as an executive coach, partnering with CEOs and executive teams to lead through high-growth, high-change environments where clear people strategy makes the difference.

My work spans talent strategy, executive development, compensation design, post-acquisition integration, and organizational effectiveness. At the core of my approach is the belief that strong business outcomes start with people feeling seen, trusted, and challenged to grow. At Orbus, I am focused on building a high-performance, high-trust culture to support the company’s next stage of growth.
