What our clients have to say

At Cro Metrics, we've run tens of thousands of experiments for leading brands, using some of the most popular and sophisticated A/B testing tools on the market. I can confidently say that Analytics Toolkit and the AGILE test calculator represent a step above and beyond every one of those tools.

Georgi has deeply mined the statistical literature to develop an approach specifically tailored to the average A/B tester: one that emphasizes speed, accuracy, and clear outcomes. It offers a huge advantage to any experimentation team. Most testing tools, if they invest in developing a statistical approach at all, often lack confidence in their users and aspire to never make them think about test design at all. Instead, AGILE balances approachability with academic rigor for a "best of all worlds" approach. I highly recommend it.

A tool with real value if you know how to use it. Analytics-toolkit's statistical calculator might seem intimidating at the beginning, but it is basically because it tries to provide flexibility, accuracy and optimization in your statistical analysis instead of over-simplification. In iSocialWeb, we mainly use it for testing and evaluation and it is definitely a must in the execution of those A/B tests and the proper analysis afterwards.

The customer support is fast and assesses you with highly-qualified responses. Highly recommended tool.

The Swiss Army knife of any self-respecting digital marketer. If your daily routine touches any kind of data or involves analysis - you need this toolkit to make your life easier and save yourself a lot of headaches.

Analytics-Toolkit is like my own personal treasure chest as it has all the tools I need in one convenient place. 6 months in and I can’t believe what an integral part of my process this toolkit has become. My ROI on Analytics-Toolkit must be in the 1000s. by now. It saves my agency hours of work in our pre & post campaign analysis but more importantly it gives us the confidence that the recommendations we make to our clients are spot on.

We've been using AGILE for a couple of months now, together with our open-source Alephbet/Gimel framework. The new API makes integration straightforward and it works wonderfully for us. We're getting results faster and avoid peeking problems at the same time, so we're much more confident.

Working with Georgi has always been a pleasure as well, and he's always open to suggestions and improvements.

I was pleasantly surprised by the suite of products offered. I had signed up solely for the AGILE calculator, but found great ease and value in using the advanced significance calculators for quick analysis. The interest in sequential testing and therefore the AGILE calculator came from reading your whitepaper, which I think every CRO practitioner should read, irrespective of where they sit on the frequentist - bayesian spectrum.

One of the concerns I had when starting to use the tool was how to communicate its value to a client that is not stats-savvy at all. This was tough, but I pushed through. Probably my biggest concern was how we would integrate the calculator with our automated reporting functions, but your API made this fairly easy.

I most definitely would recommend the toolkit, especially the AGILE A/B Test Calculator. The ability to confidently close experiments early was instrumental in getting insights fast and maintaining test velocity. I would recommend the toolkit to any CRO practitioner looking to get more out of their testing program. I would also recommend the API to more advanced users who have their own automated reporting functions. It was easy to use and allowed for data to be seamlessly pushed to the web.

Some great improvements have been made to Analytics Toolkit since it was released in Beta, and additional tools continue to be built. The value added to our agency by these tools is tremendous.

All of our clients utilize Auto Spam Filters, which are updated and pushed out automatically - we can simply set it and forget it. We regularly use the Google Update Checker, which lets us quickly identify sites that may have been penalized. Our conversion rate optimization team utilizes the Statistical Calculators for their testing.

And the list goes on - the amount we benefit from Analytics Toolkit on a daily basis is well worth its small monthly cost. I would say it provides Inflow with the best bang for the buck out of any tool we pay for.
