Like many other recent reviews, my experiences are very similar. Its so hard to identify root causes of any of the issues raised before but if I had to settle on one its that growth of the company, whilst not disastrous is not where anyone would want it to be. The problem lies in the fact that the strategy Pion have had for the past 3-4 years has not been effective nor clearly communicated. Invariably, the feeling we get is that someone in the leadership team has read a book or article and that then becomes the strategy or the terminology that becomes flavour of the month. This then defines the products, projects and other initiatives everyone works on. For the size of the company I have never seen such a top-down approach that doesn't factor in team level feedback or ideas. It feels like they know it all and do not really care what the staff feel about company direction. What this ultimately results in is all the problems every other review has cited as pain that everyone feels : Flip-flopping between projects or moving on to new things before product-market fit has been realised, no clear measures of success and measuring outputs rather that real outcomes, the sales team feeling pain of high-pressured targets, rude leadership who bully staff in the office (just to name a few off the top of my head), and of course the latest redundancies to product management and engineering. These have ultimately happened because of the original issue I have mentioned, poor direction and decision-making. Leadership have not taken the fall at all for the predicament the company has found itself in and as result it's left people who have survived feeling very unloved, demotivated and looking to leave. The attitude of leadership is that they feel they know it all and some have even told me "this is how we built the business up until this point and this is how we will continue to grow", which doesn't really sound compelling to me.
If you're into personal development I could not recommend a worse company to work for. The budgets are non-existent and they will not consider the balance of a team and work out if anyone is likely to hit a ceiling soon based on the role you and others are in, again this is a classic example of lack of strategy and poor foresight that will hurt them in the medium-long term.
The fundamental reason you're seeing so many low star reviews right now is the pain everyone is feeling from leadership who can't come up with a compelling strategy with ambitious, measure-able goals. The company will sadly continue to drift unless they change direction. It's sad that they will lose a lot of great people from across multiple disciplines.
