Coexis Limited is a software product author based in Rickmansworth, Hertfordshire, a short distance north west of London, with additional offices in the City of London and New York.

Until 1998 Coexis was known as Cumulus, which was founded as a specialist developer and provider of software to the financial markets. Products for bonds and securities settlement were installed in major banks in London, Paris, Zurich, Athens, Moscow, Warsaw, Luxembourg, Hong Kong and New York.

Ten years ago Coexis was a far-sighted proponent of a process-driven approach to software development, documenting our ideas and circulating them to the banking sector. While for many software houses this approach is now the hot issue, for Coexis our early thinking has given us a head start and in Syn software products, we now have mature and deliverable products based on this new approach.

Syn embodies 30 years’ experience of developing mission-critical applications in the regulated investment banking arena. In order to focus entirely on bringing this to market, the company sold its Cumulus product range to ADP in 1998.
