Great ELT solution and fantastic customer service **Rating:** 4.0/5.0 stars **Reviewed by:** Romain B. | Mid-Market (51-1000 emp.) **Reviewed Date:** December 11, 2023 **What do you like best about Kleene?** 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 approachableand 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. **What do you dislike about Kleene?** One thing that should be developped 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. **What problems is Kleene solving and how is that benefiting you?** Our business requires us to be flexible and to explore a lot of different directions. Kleene helps us monitor the impact of our decisions by allowing us to gather all our different sources into our data lake and run cross-functional and multi-system analysis. ### 2. Excellent **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Non-Profit Organization Management | Enterprise (> 1000 emp.) **Reviewed Date:** September 26, 2023 **What do you like best about Kleene?** Their support is timely and professional, and they are super friendly and always willing to help. They are continuously growing the platform and improving its capabilities, and in the 2 years I've been using Kleene their app has significantly improved, with tons of new functionality introduced. The app is also quite easy to use. **What do you dislike about Kleene?** Some features are still a bit basic but they are constantly reviewing user feedback and making improvements **What problems is Kleene solving and how is that benefiting you?** They are providing us with a self-service warehousing solution which allows us to more effectively report on our data ### 3. A good product paired with excellent customer support **Rating:** 4.0/5.0 stars **Reviewed by:** Luis N. | Business Intelligence Analyst, Small-Business (50 or fewer emp.) **Reviewed Date:** January 12, 2023 **What do you like best about Kleene?** Kleene has a considerable number of app integrations and the team is always building new connections which maximizes the warehousing main advantage of having all data in one place. Adding to that, setting up new connections and extractions is a simple and effortless process. Automatic data pulling has shown to be reliable, no errors until now. The highlight would be the Customer Support and Development Teams. Throughout the entire journey we have been able to provide feedback and discuss our needs (even beyond classic ETL) with Kleene's Customer Success Team. And they have been super efficient in providing answers and/or solutions. **What do you dislike about Kleene?** The SQL console still needs work. It lacks visual space in my opinion. Double console option (like Bigquery) would be great as well. I've also experienced some periods where Kleene was down, although they were not long. **What problems is Kleene solving and how is that benefiting you?** Having the main data sources in one place, allowing for quicker and more complex analysis coming from mixed-source queries. ### 4. Reliable and very user-friendly. Great functionality for creating a datalake ecosystem. **Rating:** 4.0/5.0 stars **Reviewed by:** Paul F. | Head of Data, Mid-Market (51-1000 emp.) **Reviewed Date:** September 01, 2022 **What do you like best about Kleene?** Connectors for various data sources, ability to transform/pre-process data for reducing computational time. The support from the team is great. **What do you dislike about Kleene?** One downside of using a third party to store and process your data is the response time in case of an emergency. Although, we did not have any issue with that, as Kleene's support team is very responsive to our requests. **What problems is Kleene solving and how is that benefiting you?** Kleene has helped us to reduce the cost from a data engineering point of view with the external connectors. Also, with the pre-processing functionality, we reduce computational time and overall cost. ### 5. Jamie + Dani: Kleene A Team **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Food & Beverages | Small-Business (50 or fewer emp.) **Reviewed Date:** September 05, 2022 **What do you like best about Kleene?** Great personalised service, our analyst has been super responsive and helpful. Kleene has made connection to lots of APIs + building a robust reporting structure very simple, and we are in a great place 12 months down the line. **What do you dislike about Kleene?** We were early adopters, so we were probably guinea pigs for certain aspects of the BYW process, but 100% worth it in my opinion! **What problems is Kleene solving and how is that benefiting you?** Data warehouse creation API connection ETL SQL expertise Experience with the backends of systems our business relies on ### 6. kleene ELT tool **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** August 12, 2022 **What do you like best about Kleene?** kleene is one of the best ELT tool in the industry.
