Kleene Reviews & Product Details

What sealed it for us was that Kleene team was willing to build the forecasting app with us rather than sell us a closed product. They already ran our data warehouse, so the integration story was a non-issue – every piece of data the forecast needed was already in one place, in a shape we trusted. We could shape the feature set against our actual operational reality instead of bending our process to fit a generic SaaS. That partnership model is rare. Beyond the technical build they acted as real sparring partners, and they were good at proposing solutions that addressed what we were actually trying to fix, not just the surface-level ask. Issues didn't sit in a ticket queue – we worked through them in real time. Review collected by and hosted on G2.com.

Kleene is a relatively new product. We're using it and we're happy with it, but there's still room for improvement and continued development — we're glad to be on that journey with them. When you build something new from scratch there are always teething issues, and we had ours, but they were fixed on the go through our meeting rhythm. Review collected by and hosted on G2.com.

Within 1 week we had a functional set of reports in Kleene - the speed to access data is unmatched. We did run a full data migration project which meant it took a couple of months to get fully migrated and running, but we felt the benefits within the first week.

Kleene is incredibly easy to use, great UX and very intuitive. It gives any data analyst access to be a data engineer, it is very accessible to anyone who can write SQL. In particular the pop-out SQL console, the Pipelines and Pipeline editor give you all the tools you need to quickly debug your code and manage your data pipeline.

With Kleene we have saved over 48 hours of work a week in manual reporting (i.e. 3 people x 2 days per week)

Onboarding was seemless, the customer success team are very knowledgeable and friendly. We also had access to their consultants for a few workshops to ensure that we were setting up our pipeline in the best possible way. I highly recommend this!!

We have developed multiple pipelines in Kleene:

- Full marketing: Paid Ads, GA4, Offline marketing e.g. direct mail, Emails and newsletters

- Customer service reporting: Gorgias

- Sales reporting & returns: Shopify, Recharge, Rebound

- Stock reporting: Excel files via SharePoint

- Finance and accounting reporting: Xero

We will always have more to add and expand on, but all our reporting is now consolidated under one app which we love!!

The pricing is extremely reasonable and fair, we have not had to pay for any extras beyond our initial contract value. The only add on is if we add more data connectors. They are transparent and fair. Review collected by and hosted on G2.com.

Feature requests are constant, but there are always new features we can use! They do get updated regularly! Review collected by and hosted on G2.com.

The pricing model stood out to me early on: straightforward, consistent, and offering strong value given the amount of support bundled in. That support proved reliable throughout my time with Kleene; their analysts and account managers were quick to respond, and any issues we ran into were typically resolved within a day or two.

Before long, we were able to completely rethink our reporting setup. Because everything was housed in one platform, we rebuilt end-to-end reporting suites for our two major revenue areas, which ultimately reshaped how the business worked with data and allowed for genuinely strategic, data-led decision-making.

I spent the better part of two years working in Kleene on a daily basis, and the interface, along with its editor, made routine work easy to manage. Transform logic was easy to follow, updates felt safe to deploy, and the overall workflow was far more manageable than what we’d used previously.

In fact, the migration itself was surprisingly quick. One person handled the full shift from Matillion to Kleene in roughly a month. Kleene even developed custom connectors for us, which meant we didn’t need to rely on expensive outside engineering help, especially since we had no internal data engineer.

Nothing, loved the product, would buy again if I moved company in a heartbeat Review collected by and hosted on G2.com.

We are currently working with Kleene on a second data solution, they have listened and understood our issue well, keeping in regular communication and providing updates. Phase one was a huge success, providing us with a straightforward solution that is easy to use in the given timescale saving us time and money. Review collected by and hosted on G2.com.

Nothing negative in our experience to report Review collected by and hosted on G2.com.

Been using Kleene for the past year now.

The solution was already in place when I joined the company and it's felt really easy to familiarise myself with the product.

The EL feature of the tool feels very robust already: it feels effortless to ingest data from various sources and they already have an extensive suite of connectors available.

Customer service is really attentive to our business needs and also easily approachable and reactive when there are reported bugs. (kudos to Daniella!)

As a result, the product is constantly evolving, bringing in new features and redesigning its UI to make it more user-friendly. Even if I don't get to use everything, it is easy to feel there is hard work happening behind the scenes. Review collected by and hosted on G2.com.

One thing that should be developed as a matter of priority in my opinion is the relationship between EL (Extract and Load) and T (Transform). They are still siloed while they should be treated as one pipe in my opinion.

Another smaller comment is that some SQL transforms have not been designed optimally and with scalability in mind by Kleene. Review collected by and hosted on G2.com.

The interface is very easy to use with lots of very helpful features which make using the tool quick and efficient. We have transformed analysis with the transforms tool and it's simple enough to be managed by a non-engineer. The team is always responsive to any issues and constantly push updates and new features. The cost model is different to other tools as you pay by connector, not by data volume so there is no limit on the complexity and depth of analysis you can pull out using Kleene. The team is very friendly and easy to get in touch with. Review collected by and hosted on G2.com.

Sometimes the new features are confusing and require a few iterations of feedback to get right, but on the flip side they are very responsive to all feedback and do take all customers into account. Review collected by and hosted on G2.com.

- User-Friendly: Extremely easy to use and manage, saving us time and money. Without Kleene, managing our data infrastructure would need 10x more resources.

- Robust Data Integration/Orchestration: allows us to seamlessly ingest data from various sources, with the ability to schedule and manage data cleaning scripts using basic SQL on an aesthetic & intuitive user interface.

- Customer Service: Customer service has been exceptional, providing prompt solutions and answers to any of our questions. The product's documentation is also frequently updated and immensely helpful. Review collected by and hosted on G2.com.

Nothing in particular, as any bugs are resolved promptly, and feedback is actively taken into account, with continuous implementation of new features. Review collected by and hosted on G2.com.

Everyone within the company I have dealt with has been the perfect balance of professional, affable and knowledable. Promises have always been kept and there is always a sense that you have been listened to and are valued. Review collected by and hosted on G2.com.

Naturally there has been the odd bug here and there but working in tech we all know that's to be expected. On the odd occasion it has happened there has been a timely fix in place. Review collected by and hosted on G2.com.
