As part of the series, Tech Partnership Founder Chris Hopwood sat down with Siobhan Clarke, a Chair and Non-Executive Director with more than 25 years of global experience across digital, AI, science and energy.
Siobhan’s career spans senior roles at Cisco and BP with over a decade of board experience across public, private and not-for-profit organisations in the UK and US. She’s guided companies through M&A transactions, CEO transitions and scale-up challenges across sectors as varied as energy, technology and venture capital.
Our Executive Interviews are designed to give leaders of tech businesses perspective from those who’ve seen the patterns of growth, change and leadership play out over decades. Siobhan’s experience cuts across all of them.
Our conversation explored what she’s learned from scaling technology businesses, what defines great leadership and why she believes every CEO needs a coach.
Understanding What Makes Companies Grow
When asked what separates businesses that grow well from those that stall, Siobhan begins with context. Her perspective is shaped by years spent where software, hardware and energy systems converge.
Across those worlds, two patterns stand out: clarity of value and shared understanding. “The best companies know exactly where they create value,” she said. “And that clarity isn’t confined to the boardroom, it runs through the entire organisation.”
When every team, from engineering to finance to IT, understands how their work contributes to that value, alignment becomes instinctive and growth follows. When they don’t, the business may keep moving, but it starts to drift. Drift is where good companies quietly lose their way.
Strategy Lives in Everyday Language
When Siobhan joins a new board, her first instinct isn’t to look at reports. It’s to listen. “I pay attention to how teams talk about strategy,” she said. “Do they use consistent language? Do they sound confident about direction?”
Misalignment rarely announces itself. It hides in how people speak – in hesitations, contradictions and cautious half-answers. “You can tell a lot from how people talk about senior leadership,” she said. “Is there trust and respect, or frustration and distance? Those patterns always surface long before they appear in the numbers.”
A strategy that isn’t clearly understood is as dangerous as one that’s wrong. When people understand the goal and strategy, execution gathers pace and purpose.
Every CEO Needs a Coach
The advice Siobhan most often gives to founders and CEOs is simple. Get a coach.
Coaching, she believes, is one of the most underused levers in leadership. “If you meet a coach once a month, that’s time devoted purely to thinking about yourself as a leader – not about the business or the board or investors. Just you.”
That independence is what makes it powerful. “A good coach helps you see your blind spots. They hold up a mirror, not a map,” she said. “It can feel exposing at first. You’re trusting someone with the thoughts you’d never share elsewhere. But leaning into that vulnerability changes how you show up as a leader.”
The leaders who resist coaching, she added, are often the ones who need it most. “Control feels safe, but it’s often just fear dressed as leadership. Once you see that, everything changes.”
The Art of Letting Go
Few transitions test founders more than stepping back. As teams grow, the instinct to stay involved in everything can quietly erode the trust they’ve worked so hard to build.
“The pattern I see,” Siobhan said, “is leaders hiring great people but struggling to let go. One week they think they’ve found the perfect person, two months later they’re questioning everything.”
The best leaders, she argues, strike balance. They hire people who are better than themselves in defined areas, let go of the how but stay accountable for the outcomes.
“Some founders let go too much,” she said. “Others can’t resist dictating every move. The skill is holding the reins lightly. Trusting capability while staying accountable for outcomes.”
Don’t Lose Commercial Momentum
For many high-growth companies, Siobhan sees a familiar trap…talking replaces doing.
“There’s a difference between understanding your market and signing customers,” she said. “Too many teams talk about opportunities instead of closing them.”
Sales and marketing, she added, often reflect the same issue. Both active and well-intentioned, but moving in parallel. “Each activity needs a clear purpose and outcome, or it just becomes noise. One of the classic errors is when Sales and Marketing operate on separate islands rather than a genuinely unified team.”
Her experience writing The Founder Handbook, a practical guide for early-stage companies, reinforced the point. “It’s about learning to turn discovery into traction. Whether you’re selling software or services, the principle’s the same – you have to translate insight into progress.”
Preparing for the Next Phase of Growth
When advising CEOs preparing for their next stage, Siobhan encourages them to look beyond financial metrics. “Growth isn’t just about numbers. It’s about systems,” she said. “The people, the talent and the dynamics that make strategy work.”
She frames it around three questions:
- Connect — Are you joining up the right people, teams and ideas?
- Empower — Are you giving others the authority and trust to act?
- Ignite — Are you creating the energy and motivation that keeps the system moving?
This framework comes from Third House, an organisation she’s affiliated with that develops “intentional leaders.” Their work helps leaders align the individual, the role and the wider system they influence. “When you understand how those interact,” she said, “you make better decisions.”
Preparing for growth means facing reality with honesty – seeing where talent is missing, where culture is fraying and acting before the cracks widen. “You can’t scale dysfunction,” she said. “You either fix it or it multiplies.”
Closing Thought
Throughout the discussion, Siobhan returned to one idea: leadership is a conscious act. Growth, culture and performance all depend on deliberate choices. Knowing where you add value, when to seek help and when to let go.
“Businesses that grow well do so because they understand themselves,” she said. “They know their place in the system, and everyone inside the organisation knows how they contribute to it.”
