Pros
Like most other reviewers, I will say "the people" because there isn't much to like about the company.
Cons
Featurespace is a quagmire of outdated and poorly architected software, technical debt, poorly defined or understood processes, toxic client relationships, poor communication, and career stagnation. Featurespace positions itself as a cutting-edge machine learning technology company. The reality is that the majority of projects do not involve machine learning. The technology is made up of cobbled together, outdated components which are often EOL, making it hard to implement and support, and even more challenging to stand behind to clients. Management claims that Featurespace is a company with a good culture; however, the only detectable culture is passing the responsibility for a task to the next silo along. Communication and knowledge management are worse than poor, with senior management refusing to write announcements down. Finding information is a grim treasure hunt because not only is documentation fractured and incomplete, but also information on a given topic can live in one of several different pieces of software (not to mention that one of those places is an in-house tool of low-quality). Management does not know what a healthy relationship with a client looks like - they capitulate to unreasonable requests instead of having difficult conversations that involve the word "no". This means that project teams cannot steer projects towards a healthy way of working, because they are undermined by senior management if they push back. Career and salary progression is minimal to non-existent. "Progression" in many roles is being given a small title and pay bump with no additional responsibilities or learning opportunities. Featurespace occasionally recognises some of its problems and tries to address them, but almost invariably fails to implement quality change for one reason or another. Layoffs were made earlier this year and I'd put money on there being more to come.
