I have been working with this software for over 7 years now across multiple projects at different stages from early research phase through implementation into production systems by my clients who include large financial institutions.
They provide excellent support both via phone but also email which makes communication seamless between us all round Europe (I am located near Paris). Their product roadmap always seems very well thought out so it's easy when you're given an opportunity within your project scope to make suggestions about how they can improve their offering further down the line - something we don't get too often! As mentioned above though there isn’t much room here for negativity because everything works really smoothly together without any issues during our long term relationship. We've used them primarily around machine learning/data mining algorithms including deep neural networks where accuracy was paramount along side scalability & speed considerations; however other areas were more general statistical analysis econometrics etc..
