Industry

Renewable Energy

Introduction

Nexwell Power is a renewable energy start-up with operations in Spain and headquarters in the UK. The company acquires, develops, and operates solar panel plants as part of its mission to tackle climate change. With a footprint across borders, the business faces a unique challenge: hiring finance professionals who can navigate both cultures and work effectively in a dynamic, early-stage environment.

Chief Financial Officer Chris Tawney engaged Artemis Clarke to help recruit a Financial Controller. Having experienced Artemis Clarke’s Candidate Assessment Process himself, Chris trusted that the same rigorous and insightful approach would be applied to this hire.

The Challenge

Hiring for a start-up brings unique demands, especially when the company operates internationally.

Chris needed someone who could:

  • Handle full ownership of systems implementation and accounting
  • Understand the dynamics of working across UK and Spanish teams
  • Fit the start-up culture, where infrastructure is lean and every role matters
  • Ideally speak Spanish, though this was not a mandatory requirement

Our Approach

We began by gaining a deep understanding of the role, team, and cultural dynamics.

What we did:

  • Candidate Assessment Process: Each candidate was evaluated for both technical capability and cultural fit, providing a full picture beyond the CV.
  • Bespoke Longlist: We curated a shortlist of six top candidates, three of whom were Spanish-speaking, adding value without being prompted.
  • Cultural Sensitivity: We prioritised candidates who demonstrated flexibility, start-up experience, and cross-border collaboration skills.

The Result

Chris hired a Spanish national based in London, a perfect match for both the role and the wider team.

The impact:

  • The Financial Controller quickly took over systems and accounting responsibilities
  • Chris was able to step back from day-to-day tasks and focus on strategy

Why It Worked

Unlike high-volume recruiters, Artemis Clarke takes a strategic and tailored approach to every hire. In this case:

  • The shortlist was focused, relevant, and high-quality
  • Candidates were aligned on both technical skill and cultural fit
  • Our process delivered hidden value (e.g. bilingual capability) without needing to be asked

Conclusion

This case study highlights the critical role that tailored recruitment plays in scaling international start-ups. By partnering with a specialist financial recruiter like Artemis Clarke, Nexwell Power was able to secure a Financial Controller who not only met the technical requirements of the role, but also aligned with the company’s culture and international footprint.

For CFOs navigating the complexity of growing teams across borders, having the right financial talent in place makes all the difference. Whether it’s freeing up time to focus on strategy or ensuring smoother operations, the impact of a well-matched hire is immediate and measurable.

Looking to hire a finance professional for your growing business? Artemis Clarke combines financial expertise with a deep understanding of start-up needs—bringing the right people into the right roles, every time.
