Pros
Some great people, nice office in good town centre location at UK HQ, some really interesting customers with interesting challenges. Career opportunities are good as new roles which offer opportunities for promotion come up very often for a medium sized business. Generally a pleasant place to work and there is lots of effort going into moving the business forwards (though at times this is hampered by bad decisions and apparent lack of funding).
Kontras
Shortage of QA & Product Management resources. Product is difficult to deliver for customers who require a high level of customisation as the software has not been developed with 'ease of delivery' in mind. There is a culture of "develop first, design never", which has resulted in poor product documentation and ill conceived features.
