Pros
Amazing culture
Directors are extremely down to earth
COO is absolutely incredible
Solid, well established company
Custom team provides full SDLC experience
Claromentis pro-actively recognises and enables career growth, both financially and with promotions
4 day working week
CEO, Nigel, genuinely cares about the staff and working environment. He once discontinued a contract with a client who had a homophobic agenda out of respect for the LGBTQ members of the Claromentis team. The contract was negotiated and practically already signed and he walked away from it. I actually defended that company on grounds of free speech but the fact a CEO would walk away from money speaks a lot to his strong character.
Cons
Struggles to compete with London salaries
The software is not multitenancy which creates a lot of headaches across the technical landscape
Pension contributions are "qualifying earnings" only - look this up, it's important.
