Pros

Good laptop Rewarding work when you can actually get anything done Decent pay though there seems to be a lot more penny pinching happening now

Cons

Micro-management Lots of egos Company direction changes with the wind Senior people are fired/leaving at an alarming rate (head of product, product owners, tech lead, etc.) Products have been over sold and are under delivering, genuine fear of funding disappearing because of this Product advantage has been lost due to poor delivery

Hey, thanks for taking some time out to share your experience of Sero with others, it’s super important to us that people get their say and we’re sorry to hear your experience wasn’t as great as it could have been. Appreciate you sharing your pros, glad the equipment provided was at a good standard and the salary was perceived as fair. In terms of the company changing directions, as a scale up we work in a fast paced, dynamic organisation where priorities will change rapidly in order to establish ourselves as a real competitor in the market that can adapt and meet requirements – we know this style of working won’t be for everyone. Being a scale up also means growth, in the last 6 months our team grew by 27% and in that same time we saw a turnover of 8% which is in line with the UK average of 16.8% turnover per year. As much as it makes us sad to see our team members need to move on for a variety of reasons, this is very much a part of growing and finding out everyone’s strengths and preferences. We look forward to the continued growth at Sero as we are about to receive our next round of funding and will take lessons learned on board for this next stage. It’s sad to hear that you think the Sero team members are no longer feeling positive about the work here, we have regular conversations, surveys and forums to check in but understand things fall through the gaps. We encourage all our team members to talk to the People Team or their managers at any point with concerns and thoughts for improvement. Thank you for sharing your insights, we will use them to form some of our next steps. Best of luck to you for the future and thanks for your time and effort whilst with us!

Pros

- Genuinely flexible working. Not just lip service. - Strong benefits package, including healthcare and generous time off. - Great office location and a team of capable, passionate people outside of leadership.

Cons

- When the business faced challenges, none of the senior decision-makers responsible for the issues were held accountable. Instead, cuts were made lower down, targeting junior to mid-level roles, to protect upper management and their expensive perks. While the benefits were generous, they should never have come at the cost of good people losing their livelihoods. Senior leadership should have taken accountability and fallen on their swords, rather than shifting blame onto junior teams. - Poor internal communication made collaboration slow and frustrating, even with a flexible setup. - Leadership routinely made promises to customers that weren’t technically feasible, with little understanding of delivery. Teams were pressured to support these claims, even when they were clearly unrealistic. - A strong emphasis on being a "good" company (e.g., B Corp status) often felt like a smokescreen for unethical practices — including data manipulation, dishonesty with clients, and internal retaliation when feedback was given. - Feedback culture was performative. Input was requested, but when it was honest, it was met with defensiveness or worse — consequences. - There’s a lot of talk about "family" and "everyone mucking in", but in reality this masks a top-down culture where accountability is lacking and appearances matter more than outcomes.
