Business and corporate advisers to growing companies - with corporate advisory, FD Services, outsourced accounting and HR services


We have worked with many finance teams over the years and would rate the Isosceles team as best-in-class.   Due to Isosceles’s focus and expertise,’s financial statements, reporting infrastructure and controls were in excellent shape.  As a result, a rigorous diligence process driven by a top tier private equity firm (and their long list of external advisors) was seamless from start to finish.  Together with Pagemill, we formed a formidable, results-oriented team

Matt Sachse, Managing Director, Technology Investment Banking, Pagemill Partners

Isosceles supported us from our humble beginnings right through to being a global leader in our market. We worked with some great Isosceles people throughout this time and have always very much appreciated the skills, the support and the many hours of hard work they brought.  Having a key supplier relationship for 18 years is rare, and especially when that ranges from the strategic to the daily, tactical, work.  Together we met and solved many technical and business challenges, and always in a spirit that made our relationship at all levels a real pleasure.  Isosceles has played a big role in our success for which the shareholders, executives and indeed the whole team are very grateful.

Alwyn Welch, Chairman,

It is difficult to find a company like Isosceles that is able to effectively, efficiently, and with a great personal touch deliver such a breadth of financial services. Our work with Isosceles has had a tremendous impact on our business and has definitely generated a positive ROI.

Kenny Dunn, Founder and CEO, Eating Europe

Isosceles is an integral part of QiO’s journey, from our basic finance needs to accounting, payroll and tax activities in six countries, they provide outstanding responsiveness and teamwork to meet our needs.

Baz Khuti, Founder and CEO, QiO Technologies

Isosceles have provided a tremendous level of support throughout.  They ran an effective process and identified an international buyer outside of our immediate network of business.  Their blend of corporate finance and accounting skills proved invaluable.

Dr. Tim Wallis, Managing Director of Ridgeway

Isosceles was exceptionally easy to work with from the very first meeting.  They are an instrumental part of the team.  We look forward to expanding our relationship and working together for many years to come.

It is very reassuring to have the Isosceles HR team on hand with knowledge and resources to help us with any HR issues at any time in the UK and beyond.

Clive Bellmore, CEO, Europe & Africa, Back Office Associates

Isosceles feel like part of our team. They got the HR service up and running very quickly and it’s a real support to have their expertise.

Neil Clark, CEO, PrimeVigilance

Expansion into Europe is a key strategic goal for our company.  With so many decisions to make it is great to have an experienced partner like Isosceles to take the compliance headaches away allowing us to focus on the big commercial decisions
