North East-based technology consultancy Test Driven Solutions (TDS) is celebrating a period of exceptional growth and success as it continues its expansion across the UK and internationally, with a new office opening in Edinburgh early next year and plans underway to launch a base in Latin America in 2026.
Founded in 2020 by Sam Clark, TDS has rapidly established itself as one of the UK’s fastest-growing software consultancies, specialising in software development, testing, platform engineering, and user-centred design.
Since its first revenue just five years ago, the company has grown from a six-figure start-up in year one to an eight-figure global business five years later, reflecting exceptional year-on-year growth and rapid international expansion, all built on organic, self-funded growth, without any external investment.
This growth has been driven by the company’s quality-first approach, high technical standards, and a culture that puts people at the heart of everything it does. What began as a one-person start-up has grown into a global business of more than 160 people, with offices in Newcastle, Poland and Canada. Together, these teams provide around-the-clock support, helping TDS deliver cutting-edge solutions for clients across financial services, the public sector, and beyond.
As part of its next stage of growth, TDS has introduced a senior leadership team with several key appointments joining the company over the past few months:
These appointments reflect TDS’s commitment to strengthening its foundations while pursuing ambitious expansion plans. The upcoming Edinburgh office will build on the company’s strong presence in the North and Scotland, supporting new and existing clients while creating new opportunities for local talent. The planned Latin America base will further extend TDS’s international footprint, offering clients global delivery capabilities.
Looking ahead, TDS plans to continue growing its team and expanding its global presence, exploring new markets and industries while building on the strong foundations that have driven its success to date. The company’s long-term goal is to be recognised as the UK’s go-to consultancy for organisations seeking high-calibre, technically excellent software delivery teams, while maintaining the culture and values that have been central to its success.
Sam Clark, Founder and CEO of Test Driven Solutions, said: “When I founded TDS, my goal was to build a consultancy that truly cared about its people, one where quality, culture and collaboration came first. The growth we’ve achieved over the past five years has been incredible, but it’s been built on our values and our people.
“As we enter this next phase of expansion, I’m proud to welcome our new leadership team, who bring the experience, insight and drive needed to take TDS to the next level, while staying true to who we are. The opening of our Edinburgh office and our expansion into Latin America mark an exciting new chapter in our journey, and I’m confident the best is yet to come.”
The new leadership team shares that vision and enthusiasm for the future of TDS. Together, they bring a wealth of experience across technology, finance, operations and commercial growth, each focused on strengthening TDS’s position as a trusted partner for clients and a great place to work. Their collective priorities include expanding the company’s service offering, embedding innovation through AI and emerging technologies, enhancing operational excellence, and ensuring that TDS continues to grow sustainably without losing the culture and authenticity that define it. With this blend of strategic insight and shared purpose, the leadership team is united in driving TDS toward becoming one of the UK’s leading consultancies for quality-driven technology solutions.
A core part of TDS’s people-first approach is its commitment to nurturing talent and inclusivity. The company’s graduate scheme gives recruits hands-on experience across development, testing and DevOps before specialising in one area, creating a clear progression career pathway. TDS also champions neurodiversity and individuality in the workplace, a value that’s especially close to founder Sam Clark, who was diagnosed with autism a few years ago and has made it his mission to ensure every employee can thrive in an open, supportive environment.
With nominations for Technology Business of the Year at the Lloyds Banking Group 2025 Business Awards, TDS’s momentum shows no sign of slowing. The company continues to focus on sustainable, people-first growth, offering clients exceptional service through its team of highly skilled consultants, and creating an environment where local talent thrives.
