“Spencer Rigby understood our strategy, culture and purpose from day one.”
· Former CEO, WerfenScaling leadership without losing what made it work.
Werfen are in a state of business evolution, requiring talent that can help the organization reach its future state. They require leaders that will gel into their unique culture and support the business through the transformation of people, systems and processes to scale. It’s integral this is achieved without it feeling like a revolution, requiring the perfect type of leader to straddle successful history with new, scalable ideas.
During this process, they have also been going through an entire people function evolution. Without an established Talent Acquisition function, Spencer Rigby has played a large role in improving talent acquisition strategies to deliver longer lasting results while also managing the workflow of how searches are prioritized and performed.
You will see from the placements, that we have touched every corner of the business to deliver the leaders that will shape the future direction of the business, covering almost every function across seniorities from Sr Manager right through to CEO.
The transformation of people, systems and process has to scale the business without it feeling like a revolution, protecting what already works while building what's next.
That takes leaders who gel into Werfen's unique culture and can straddle a successful history with new, scalable ideas.
Werfen was going through a wider people function evolution too. Without an established Talent Acquisition function, Spencer Rigby helped build one, improving strategy for longer-lasting results and managing how searches are prioritised and run.
The placements below show that reach: we've touched every corner of the business, covering almost every function and seniority from Senior Manager through to CEO.
Werfen is the one organisation we don't proactively approach on behalf of other clients — a boundary we hold as a matter of course wherever a partnership runs this deep.
What our partners say.

They invest the time to deeply understand our culture at Werfen and what makes us unique, ensuring every search aligns with our values and the specific needs of each role.

“During the past two years, I have had the pleasure of leveraging the recruiting capabilities of Nathan Rigby and Daniel Spencer. I have found both to be hard working, diligent and reliable when it comes to identifying and presenting candidates for key C Level and Director level roles that are critical to our business. They have great insights to the industries in which they serve and pride themselves on understanding their client's culture and needs.”
“Daniel Spencer and his team at Spencer Rigby were outstanding partners throughout my job search, providing a highly personalized experience at every step of the process. From the beginning, Daniel demonstrated a deep understanding of the companies he represented, their strategies, culture, people, and the purpose behind each role. What I appreciated most was Daniel's communication and transparency. You always knew where you stood in the process, with timely, honest feedback after every interaction.”
“We wanted a recruiting partner who looks beyond the CV, someone who understands motivations, values, and cultural fit as much as the role itself. Daniel takes the time to understand people on a deeper level, not just their experience and qualifications, but what motivates them and where they can truly thrive. By prioritising cultural alignment alongside the core responsibilities of the role, Daniel consistently creates true win-win matches that drive long term success for individuals and organisations alike.”
“Nathan has been a great and trusted partner to work with for multiple roles at our organization. He has been responsive at all hours of the day and night and provided high quality candidates based on our needs. Nathan knows the diagnostic industry and is truly an expert in his field.”
“Nathan delivered exactly what we asked for: high quality candidates with the specific subject matter expertise and experience that we needed. Nathan was very responsive and quickly addressed all feedback that I raised with him. I am so happy with Nathan's work and will definitely work with him again for future hiring needs.”
“After 4 long months of searching for the perfect candidate, Nathan contacted me with one candidate that he believed is the right one for our business. Lateral flow diagnostics is a narrow field within diagnostics and Nathan is well connected in the industry. At all times, Nathan did not chose a side and made sure that we were both updated real time on the details. I strongly recommend Nathan for your hiring needs.”
“Nathan is a talented networker and connected me with great people in the global IVD industry. He is a skilled communicator, and has a brilliant understanding of company needs and market trends, therefore he can connect the best and right people for the right role at the right time.”
“We engaged Nathan to headhunt senior life science candidates for our business based out of Europe and North America. Nathan listened to the brief and only provided top class candidates that wanted to engage. Nathan became in essence our brand ambassador and I cannot recommend him highly enough.”
“Every talent acquisition manager should have a partner such as Nathan Rigby. He is a great listener and participates fully to secure talent for an open position. We collaborated with Nathan on a number of open positions that were tough to fill. He did his best to secure top talent that met the job description to the letter. We greatly appreciate his willingness to be flexible, determined, and thorough.”
