HR is more than just a job title to e-volve

We carved out our HR careers working with some of the biggest and brightest organisations in the UK. Regardless of size, everyone we work with shares some common traits. They are vibrant, creative and visionary. These values matter to us and it is that energy that keeps us coming back for more.

After leaving corporate HR life, e-volveHR developed from a seed of an idea, nurtured by our founding directors Sarah Stevens and Lisa Hallewell. Together they have 50 years’ experience working at all levels of HR, in a broad range of companies.

Today, e-volveHR specialises in supporting the technology, gaming, sciences and bio-tech sector. The innovation we see every day is truly inspirational. We are driven by the fact that our HR expertise will contribute to your business growth. From there we could see the next life-changing scientific development or technological advance. 

Our core values


We have earned the ability to be creative, using our experience to think strategically about problems and respond to them with innovative solutions.

Clear Impact

We take the quality of our work personally. Quite simply, if it doesn't add value, we don't do it, it's built into our DNA to measure our success by the impact we have for clients.


Our passion comes from how much we care, about people, about the work we do and the businesses we work with.

Cut through the noise

Pragmatic and to the point, there’s no corporate jargon or HR fluff, we believe in honest dialogue. We don’t do BS, we have integrity and do what we say we will.


Paying attention to the effect of short-term actions on the long-term growth and profit of your business.


Working so closely with our clients that we become part of the team, working in partnership to implement solutions.


Based just outside Oxford, we offer support UK-wide. Typically, our niche of working with fast-paced, growing tech and science companies means we are drawn towards the magic triangle of Oxford, Cambridge and London. In fact, e-volveHR has been referred to as the ‘best-kept secret outside of London’ in HR circles. Wherever you are based take a look at our HR Services to see where we can support you.
