About Isosceles Finance

Isosceles Finance is a business accounting and HR consultancy, founded in 2001 by the CEO, Mike O’Connell, a Chartered Accountant who qualified with Ernst & Young in London.   

Through work with investors and early stage companies, Mike realised that emerging and growing businesses need an effective accounting function and HR function just as much as well established corporations.   The challenge these organisations face, however, is how to afford the calibre of staff and systems required to help them grow and prosper.

Isosceles was founded to provide clients with affordable ‘best in class’ accounting andHR support in the form of interim, part-time and outsourced accounting solutions and outsourced HR through all stages of evolution from start-up to exit.  In the past seven years we have helped over 90 ambitious businesses realise their potential.

Our clients are largely early stage, funded or rapidly growing companies. Our clients include four recipients of the Tech Track 100 Award.  Our largest client is a fully listed £200m turnover company, and our smallest is an Imperial College spin-out.

 The Isosceles service is not a ‘one size fits all’ – each client has their own service delivered to their individual requirements.  Our service portfolio includes:
