Meet the Team

Bill Berry


Bill has over 30 years’ experience in the telecommunications industry and is a leading expert on the use of GSM communications in a machine to machine (M2M) environment, particularly in the electricity industry.

He brings valuable experience to the team, both in terms of secure communications infrastructure design and his history of building successful technology and communications businesses.

In his early career, Bill managed the Industrial OEM Division at Dataflex Design which was subsequently acquired and grew to over £42m revenue.  Seeing the growth in Dataflex and the future opportunities in data communications, Bill led a buyout of the Industrial OEM Division from which he built his company, ASL Holdings.

Following ten years of successful growth, ASL was acquired in 2013 by Halma PLC, a FTSE 250 company.  Bill remains its CEO under its new ownership.

Simon Nash


Simon was originally CFO for the Cresatech group, but has since taken on the wider role of CEO. He is a Chartered Global Management Accountant and a fellow of the Chartered Institute of Management Accountants.

After an early career as an electronics engineer, Simon changed direction after joining a fast track management development programme.

After graduating in business studies he qualified as an accountant in 1993. His first Finance Director role was for software specialist PWA Group in 1995, where he led it through significant growth, including a VC fundraising and its subsequent sale to Great Plains Software (now Microsoft Business Solutions).

In 2004, Simon created SRN Associates, a financial management consultancy focusing on growing technology companies, through which he helped over 20 companies develop and implement growth strategies; a role that has also included corporate finance transactions ranging from acquisitions, corporate restructuring, fundraising and M&A work.

He has worked with established names, such as SunGard, Great Plains, Halma, and Microsoft as well as a wide range of VC and private equity backed companies.

Outside the office, Simon is a keen runner, and enjoys reading, music, playing keyboards (badly), and travelling with his wife Alison, and his (almost adult) kids.

John Wybrew OBE


John has had an extensive career in the energy industry. In the late 1970s, he managed Shell/Esso’s gas production operations in the Southern North Sea before moving to the position of Technical Director of Shell’s major oil and gas exploration and production company in Brunei.

He then moved to head up the Planning and Economics Division of Shell’s E&P Co-ordination in The Hague.  In the 1980s, he was seconded for three years to the Prime Minister’s Policy Unit as Mrs Thatcher’s adviser for energy and transport, returning to join the Board of Shell UK as Planning and Public Affairs Director.

His later career included a period of eight years as Executive Director of British Gas and a Director of National Grid Transco (now National Grid).  John also served as a Non-Executive Director on the Board of the UK Energy Regulator, Ofgem, from 2004 to 2012. In 2004, he was also Special Advisor to a House of Lords Sub-Committee inquiry into the security of future gas supplies. He chaired the British Energy Association from 2005 to2007, and still chairs the Foundation for Management Education.

Since then, he has had a portfolio of interests, until 2009 including chairmanship of a Government-backed Sector Skills Council set up to anticipate and tackle the skills needs of the gas, electricity, water and waste management industries, for which he was awarded an OBE.

Today, he is active on the boards of one or two new and developing businesses in the energy sector. He holds a first class Honours degree in engineering from Cambridge.
