Pros

It goes a long way getting along with the people you work with. I have a lot of trust in the leadership and direction of Jellyfish. The GTM team is working hard. High class team.

Cons

Product needs to move even faster than it is today. CSM org provide little value.

Pros

- The core product is a good idea, but poor execution. The acquisition of a competitor confirms Jellyfish is solving a real problem in a real market. But the broader software market is unwell. I don't think there will be a $ billion + exit in this space.

Cons

- Resource management is a serious problem here. The company preaches frugality as a core value, but the reality is the opposite. For a 200-person startup, the monthly cloud computing bill is staggering, and budget gets burned on unnecessary speakers and consultants that add zero value. - Shipping is unusually slow for a startup. Weighed down by administrative bloat and a dev environment that feels years behind where it should be. The people in the middle aren't removing obstacles; they're creating them. If the right managers were in these seats, this company could accomplish more with a leaner team. Some teams are definitely better but the fact that there is a lot of variance is a sign of an issue. - Lots of internal conflicts. Fights are a regular occurrence. You'll either be in one, witness one, or hear about one. At some point, the wrong people were hired or promoted into leadership (middle and upper), and the cultural damage has been significant. Unless that's fixed I don't think the company will go nowhere. - All of the above flows to product reliability issues. Churn rate is bad.

Pros

The market is heating up. The acquisition of the main competitor (DX) by Atlassian for $1B (!!) a few months ago put a spotlight on our category and also on Jellyfish. The product is mature and also leading the AI measurement race to give engineering leadership the right insights. Remote work (for those outside Boston) is the norm, and everyone is great at it. The majority of senior executives have families so they understand the need for spending time with your kids, providing good work-life balance. Work is interesting, you are at the very bleeding edge of AI transformation and learning every day. If you work here, you'll know everything (whether you want it or not) about AI and how it is changing software development. Great learning opportunity.

Cons

It's a startup that has had to quickly adapt to AI, and the product is undergoing a major transformation. Competition is heating up so we can't rest on our wins and there are aggressive growth targets. Tight budgets for marketing, sales, everything basically. Not that they are skimping but you have to make a case for spending on stuff. Expected at this stage but may put some people off. No office to go to other than Boston. Most customers love Jellyfish, but churn does happen. Comp is average, but typical for startup at this size.
