Pros

Good Solutions and good people.

Cons

The leadership abandoned customer centricity by hiring someone who did not appreciate or understand customer advocacy. This individual stated that he knows if a customer is happy and would retain our solutions by the first month. This is the kind of irresponsible management of the head of operations. This is the kind of leadership that is crippling this company with decent technology.

Thank you for taking the time to share your feedback with us. We’re not sure if you’ve accidentally left a review for the wrong company as we do not recognise several points in relation to our company and structure. For example, we do not have the role of Head of Operations nor have we had employees based in California City. However, in the event that the review is meant for us, we appreciate your honesty and are glad to hear your positive notes regarding our solutions and the talented people at Hazelcast. We take all concerns regarding customer centricity and leadership very seriously. Providing value to our customers is a core priority, and we acknowledge your perspective on how leadership decisions impact that mission. We are actively working to improve how we share our vision and support our teams through these shifts. Your insights are valuable as we work to strengthen our strategy and management approach. If you'd like to share more specific thoughts or further discuss your experience, we would welcome you to contact the people team directly. We appreciate your contributions and wish you the best in your career."

Significant issues.

Pros

- A product that works well and fits various use cases. - A notable customer base with recognizable names. - Open source prospects to call on that have a history with the product. - Some name recognition with developers. - One company-wide day off after each quarter’s end.

Cons

- Open source version is too good: the open source product is too performant for Hazelcast’s own good. It’s so reliable that an open source user can run mission critical workloads on it with no downtime. Therefore there is no reason to buy Hazelcast Enterprise. - Major customer churn: the churn is very serious. - No clear vision: too many people and ideas competing internally, too many leaders working against each other, too much turn over in key leadership positions and too many false dawns on meaningful changes. - Low Pipeline: it’s nearly impossible to build pipeline at Hazelcast. There’s so little compelling info given internally that it’s hard to make a compelling case externally to prospects about the value it brings. New deal size is about 50k and that keeps the pipeline very low. In order to maintain a healthy pipeline you need a huge number of opportunities, which come infrequently. Most of the pipeline generated here are recycled opportunities from past closed/lost deals. There is a community of open source users who refuse to buy Enterprise Hazelcast and reps tend to reopen recycle these frequently until they finally decide to move to Enterprise. There are a very small handful of accounts or opportunities where you can sell 7 figure deals, large banks only. Too many factors work against building meaningful pipeline. - No partnership team: there are no significant cloud or service partners to speak of. There’s nothing driving revenue to Hazelcast via any partnership, all the selling is done by Hazelcast alone. Most successful companies have a healthy partner ecosystem that sends some revenue their way, Hazelcast doesn’t. - No onboarding process: there is no formal onboarding which explains what has worked, what the value of Hazelcast is, how the tech works (in depth), who the customers are, successful use cases, what kind of ROI the product delivers, etc. You learn bits and pieces over time that were better explained during onboarding. Hazelcast has the responsibility to equip you with the info you need to do the job, and instead, they put that responsibility back on you. There are frequent complaints from leadership about how unequipped their teams are but no action taken to help them close the gap. - Communication is lacking: a lot happens at the leadership level that isn’t disseminated down to the people on the ground. There’s little communication on a team to team basis which makes each team feel like they’re in a silo.

Pros

Hazelcast has a strong open source following which is a good and bad problem in that the software is used everywhere yet we have not determined a way to make money from it in a “sticky” way.

Cons

Notably we have lot a number of key accounts and continue to do so. The innovation speed has fallen through the ground with a single unexciting product release targeted for 2025. The company is rudderless and increasingly soulless. Very few inspiring people on the team with the weakest CEO I have observed in my career. The company has lost its way and feels irrecoverably damaged through inter department and leadership skirmishes. The world of technology is exciting everywhere but in Hazelcast in 2025.
