If you are in any type of sales, and meeting with people, it is a must. If you already know you contact well, it doesn't have as much value for that particular meeting. Also I wish there was a way to not sync internal meetings, as it just provides clutter, and I don't need info on those people.
1. Looking up the technologies, analytics tools, and services used by your competitors and industry leaders. 2. Checking what has changed technology-wise on the website of your competitor, since you've noticed an improvement in their rankings or other website improvements. You can even set up alerts to receive emails every time a new change was made to the technology of the website you're interested in (usually your top competitors').
We were considering changing a hosting provider because we were not happy with the speed of our website. So, we used SimilarTech to look up which hosting providers our competitors and some other faster websites were using, to help us make an informed choice.
When the company was considering a new live chat vendor, we also used SimilarTech to see what software some of the best websites on the web are using.
Given the tasks SimilarTech was designed for, I don't really think there are any issues with it. It's hard to think of a situation where I couldn't get the information I needed from SimilarTech.
The thing that Charlie does best is it aggregates everything in one place. It allows me to have a one-stop shop, that I can quickly review prior to heading into a meeting. People are usually amazed with the amount of info that Charlie can give you, and it almost always works its way into my sales call.
Overall SimilarTech had a positive impact, as it saves a lot of time (days) when it comes to research of the competition and new up-and-coming technologies for our website.
Moreover, it helps to monitor updates on the websites of the industry leaders, and to keep up with tech.
