A trustworthy, no-nonsense, opinionated experimentation platform **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software **Reviewed Date:** June 25, 2026 **What do you like best about Confidence by Spotify?** It is very clear that the confidence team has deliberately decided to nail the fundamental features with a clear goal in mind - everyone should be able to plan, run and analyse experiments without having to rely on a data scientist - which is exactly what has happened at Mentimeter. Now that teams are able to self serve the execution, data scientists/analysts are able to focus on finding opportunities and estimating impact. I highly value the research based heuristics that are embedded in the experimentation platform, it gives a clear signal on when to ship and when not to. Thanks to their commitment to OpenFeature compatible SDKs, feature flag implementations are super smooth and vendor lockin is reduced. Last but not least, the support from the Confidence team has been instrumental, everything from statistical concepts, metric design and technical troubleshooting is usually less then an hour away. **What do you dislike about Confidence by Spotify?** Nothing to be honest but I would love to see CMS-integration in the future to enable content designers to easily run experiments without developer intervention. **What problems is Confidence by Spotify solving and how is that benefiting you?** Making feature management and experimentation self serve which has immensely increased adoption. ### 2. The Most Reliable AB Testing Platform We've Used **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software **Reviewed Date:** June 25, 2026 **What do you like best about Confidence by Spotify?** We've been using Confidence for the past two years, and it's become an essential part of our experimentation workflow. It allows us to run multiple experiments in parallel with confidence, and for the first time, we truly feel we can trust the results of our AB tests. Beyond the product itself, the Confidence team has been incredibly supportive and responsive whenever we've needed help. Their partnership has made adoption smooth and successful. Overall, Confidence is the best experimentation platform we've used, and we'd highly recommend it to any team serious about running reliable, scalable experiments. **What do you dislike about Confidence by Spotify?** Honestly, we don't have any major complaints after using Confidence for the past two years. The product has been reliable, the experimentation capabilities are excellent, and the support team has consistently been responsive and helpful. **What problems is Confidence by Spotify solving and how is that benefiting you?** Confidence solves one of the biggest challenges in experimentation: flexibility. Unlike many experimentation platforms, it's modular and doesn't force you into a single way of working. We were able to integrate it with our existing data infrastructure, choose the statistical methods that best fit our needs, and adapt it to our experimentation workflow rather than changing our workflow to fit the tool. That flexibility, combined with reliable experiment analysis, has made it much easier for us to scale experimentation. ### 3. Finally, a platform that's just right **Rating:** 5.0/5.0 stars **Reviewed by:** Omar M. **Reviewed Date:** June 24, 2026 **What do you like best about Confidence by Spotify?** It's "just right". Confidence has all the right features and none of the bloat. Before we found it, we cycled through countless products, and there was always something broken, missing, or some use case they couldn't handle no matter how much extra patchwork we threw at it. With Confidence, everything "just worked". We run all our feature flagging and experimentation on Confidence. The architecture is solid and gives you the right tools you need to run reliable experiments at scale. The seamless warehouse integration saves us huge amounts of time on experiment analysis, and it works really well with our event streams, so we can set up guardrails and metrics without any ETL. Being able to deploy sidecars on our own infrastructure has given us real control over our scalability and uptime. Being able to have reviews and comments on experiments has been fantastic for our analysts, helping others across the org avoid mistakes and making it far more scalable and self-service to set up experiments company-wide. We're now also exploring Confidence's MCP to automate our entire experimentation setup. We were an early adopter and the Confidence team has been amazing at responding to our feedback and watching how much they've improved it over the past years has been inspiring. They are a passionate group of people who continue to build a really well thought-out product. **What do you dislike about Confidence by Spotify?** I'm not sure I have any, we have everything we need to be honest **What problems is Confidence by Spotify solving and how is that benefiting you?** The core problem Confidence solves for us is running experiments and rolling out features at scale — including targeting specific user cohorts with features and content. It allows us to do this with self-service tooling and easy collaboration, which means teams can move independently. For many of our teams, it's become essential to how they operate day to day. ### 4. It's a great platform in which improves constantly! **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Banking **Reviewed Date:** June 23, 2026 **What do you like best about Confidence by Spotify?** Confidence tries to keep the statistical details on a reasonable level, if you don't have too deep knowledge within statistics you can still use the platform since you get alerts and recommendations which tells whether your feature should be shipped or not. The bootcamp i would say is one of the best parts as well. **What do you dislike about Confidence by Spotify?** I think it still requires people knowing statistics quite well to be able to do experiments and interpret the results. I'm not saying its an issue of Confidence, A/B-testing is just complex by nature. But with that said I think there are still things that could be done in Confidence to make it easier :-) It's quite hard to calculate MDEs and NIMs for the teams even though the sample size calculator exists in the bootcamp, do you think something could be done there? As an administrator, I'm been struggling with the operational part, for instance if data has not been exported correctly into Confidence during the weekend. The lineage part has developed, so that is great, but the ideal would be to look up the fact table, see if its used in any active experiments, and then be able to do the retrigger from the fact table, not go to every experiment. The MCP server really helps with the lineage as well, so thats great. I love that Confidence develops so fast, but sometimes it's hard to keep up. Do you think you could have a popup or splash or news sections in the UI? That informs the user of the new cool stuff you have added? :-) Even though I appreciate the change log in our shared slack channel with you! **What problems is Confidence by Spotify solving and how is that benefiting you?** Making it so much easier shifting the focus from "just shipping features" to "scientifically proving impact", helps us to understand our customers on another scale. ### 5. A bit steep learning curve but good potential for AB testing at scale **Rating:** 4.5/5.0 stars **Reviewed by:** Charikleia A. **Reviewed Date:** June 22, 2026 **What do you like best about Confidence by Spotify?** Really good customer support that really takes on feedback and responds really quickly. Easy to support and organise lots of experiments across different areas and heave everything in one place. Constantly improving and adding more services - including in the AI space. **What do you dislike about Confidence by Spotify?** Seems easy to use at start but lots of small things here and there resulting in an initially unexpected steep learning curve of how to use it right. Not all pitfalls are easy to notice before you actually have done and failed with few experiments. But customer support is really quick, helpful, and takes on feedback to kill bugs, improve performance and create new features. **What problems is Confidence by Spotify solving and how is that benefiting you?** I am a product analyst in a tiny data team, so the problem it solves from my end is that the data team is not a bottleneck for lots of concurrent tests running across different areas that would traditionally need analysts to help setup and analyse. In that way the data team can focus on fewer more 'interesting' or complex cases and follow ups instead. ### 6. Powerful, scalable and attentive to our needs **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Accounting **Reviewed Date:** June 25, 2026 **What do you like best about Confidence by Spotify?** Not having a build a separate infrastructure to measure outcomes of experiments, the tool connects to data that we already produce. This can be behavioural data from frontend analytics tools but also transactional data from backend systems. **What do you dislike about Confidence by Spotify?** It does have a quite high learning curve where I at times can be uncertain on the best ways of actually setting up and monitoring experiments - the tool is flexible but that also comes with a complexity. **What problems is Confidence by Spotify solving and how is that benefiting you?** We want data driven decision making in product development and this tool is an enabler for that. It gives us a controlled way of testing new features, rolling out value adding winners to our customers and at the same time not rolling out features that do not add value. ### 7. The whole package - from tools to education modules, makes experimenting possible **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Investment Banking **Reviewed Date:** June 25, 2026 **What do you like best about Confidence by Spotify?** I find that Confidence provides a really strong user interface and a great depth of features that make experimenting highly accessible. It does an excellent job of accommodating a wide variety of workflows by packaging everything—from feature toggling and rollouts to A/B testing, segments, analytics, and educational modules—into one seamless experience. **What do you dislike about Confidence by Spotify?** I have not found anything to dislike yet. **What problems is Confidence by Spotify solving and how is that benefiting you?** Confidence solves the massive challenge of feature management and experimentation, which was incredibly tricky and manual to handle without a proper tool. It allows us to safely roll out new features in controlled stages. By pairing this with robust A/B testing capabilities, Confidence gives us the infrastructure to experiment safely and make data-driven decisions without the usual friction or technical overhead. ### 8. Great product - has everything I need **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software **Reviewed Date:** June 26, 2026 **What do you like best about Confidence by Spotify?** For me it's the responsiveness of the team at Spotify. Whenever we miss something, we basically say the word and then we have a solution that works for us right away. **What do you dislike about Confidence by Spotify?** I've been using it since very early days though so of course there has been some quirks here and there along the way, but overall everything is moving in the right direction. **What problems is Confidence by Spotify solving and how is that benefiting you?** Confidence makes us able to very granularly AB-test, feature flag and roll out new features. It makes it very easy for us to target specific app versions so we can align rollouts on different platforms with very basic (or very advanced) rulesets. ### 9. Feels more like a partnership than just a SaaS. **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Consumer Services **Reviewed Date:** June 18, 2026 **What do you like best about Confidence by Spotify?** 1. Easy-to-use UI with lots of helpful features 2. Ease of integration via OpenFeature 3. APIs for programmatic access 4. (last but not least) Confidence team is very responsive and constantly iterating. **What do you dislike about Confidence by Spotify?** Not sure it's a "disadvantage" but I don't know what the experience would be like working with Confidence as a very small entity with minimal funding, e.g. if I was a one-person team bootstrapping a small startup. **What problems is Confidence by Spotify solving and how is that benefiting you?** Confidence, as a platform, seems pretty battle-tested. I really like how it's tied into our GCP backend directly so we can own the data. ### 10. Finally I could see the outcome of my experiments **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software **Reviewed Date:** June 25, 2026 **What do you like best about Confidence by Spotify?** It's an easy way to get control over rollouts, experiments and see their actual outcome. **What do you dislike about Confidence by Spotify?** Flag rules can sometimes be a bit tedious to set up. It would be nice if the system to add rule templates that can be reused on flag creation. **What problems is Confidence by Spotify solving and how is that benefiting you?** It allows us to do controlled roll-outs/experiments of new features while keeping us informed about what effects our changes actually have on user behaviour. This has normally been something that takes a lot more effort to achieve. ### 11. Improved speed & quality of experimentation **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in E-Learning **Reviewed Date:** June 23, 2026 **What do you like best about Confidence by Spotify?** Highly opinionated on experiment outcomes. Like having a group of phd statisticians hired at the company. **What do you dislike about Confidence by Spotify?** Different design in how to setup experiments compared to previous tools so we needed to change how we target/expose users to different treatments. But got a lot of support from the team to change wow with targeting as smooth as possible **What problems is Confidence by Spotify solving and how is that benefiting you?** Interpreting experiment outcomes and helping people conduct proper statistical analysis. ### 12. Easy, fun and educational **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Investment Banking **Reviewed Date:** June 26, 2026 **What do you like best about Confidence by Spotify?** Educational material. Many smart functions to make complicated things easier. Nice UI. Easy to collaborate. **What do you dislike about Confidence by Spotify?** Sometimes hard to understand the underlying problem when something goes wrong. **What problems is Confidence by Spotify solving and how is that benefiting you?** Understanding how the users use new functions, what has a positive effect on the user experience and what doesn´t. ### 13. Advanced in a good ways. When first starting it feelt overwelming, but no it feels powerful! **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Financial Services **Reviewed Date:** June 22, 2026 **What do you like best about Confidence by Spotify?** Robust and keeping me on the right track when it comes to testing. **What do you dislike about Confidence by Spotify?** It's hard to learn. It's not a "plug and play" experience **What problems is Confidence by Spotify solving and how is that benefiting you?** Testing and experimentation in the right way! ### 14. 10/20 **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Banking **Reviewed Date:** June 25, 2026 **What do you like best about Confidence by Spotify?** Learning about users behaviour and by making more and more detailed experiments. **What do you dislike about Confidence by Spotify?** Lack of separation between test and prod environment. **What problems is Confidence by Spotify solving and how is that benefiting you?** Secure rollouts and A/B testing personalized marketing material. ### 15. Polished packaging of stasticial sound controlled experiments with effective metrics integration **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Financial Services **Reviewed Date:** June 18, 2026 **What do you like best about Confidence by Spotify?** The quick support and the documentation that underpins the advanced statistics. **What do you dislike about Confidence by Spotify?** Changes are made to the service outside our control **What problems is Confidence by Spotify solving and how is that benefiting you?** Roll-out and experimentation for our end users ### 16. Good structure for ab tests explaining statistical significance **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services **Reviewed Date:** June 25, 2026 **What do you like best about Confidence by Spotify?** Help about statistics to explain to our users **What do you dislike about Confidence by Spotify?** Sample size caluculator seldom works or i dont understand it **What problems is Confidence by Spotify solving and how is that benefiting you?** Ab testing, testing metrics ### 17. Streamlines the A/B testing process **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Health, Wellness and Fitness **Reviewed Date:** June 25, 2026 **What do you like best about Confidence by Spotify?** built-in sophisticated statistical methods **What do you dislike about Confidence by Spotify?** easy to miss errors in resulting metrics SQL - it's under the hood **What problems is Confidence by Spotify solving and how is that benefiting you?** ab testing ### 18.
