Datanyze can be a useful tool for understanding your market. You're able to use Datanyze to see how many people are using your technology as well as who is using your competitors. Receiving alerts on who is adding and dropping you vs your competitors is always helpful. It's a tool that can potentially give back as much as you put in.
Its well suited If you find yourself manually placing contact details in CRMs or you're using multiple tools to find relevant and accurate contact details. Not so relevant if you already sheet of contact details and you can simply import it as a CSV in certain tools
Datanyze used to give really good data on specific person level. You could then look up prospects using the Chrome extension inside of LinkedIn. This made prospecting extremely easy and very efficient. Unfortunately, this no longer exists and it is much harder to do without their data.
I have found that sometimes the data inside of datanyze is not always current. When reaching out to companies they will mention that they were just testing a tool, not fully using it.
There are really no other places to push the data from Datanyze except for Salesforce. This makes it tough when using other tools or CRMs.
Super easy to use, the only thing I wish they would change is that you always need to check the prospects linkedin page to see if there's been an update to their contact (eg. if contact didnt have a mobile number saved, they may now, so you need to check linkedin every single time before reaching out). Other than that, this is by far the best tool for pulling numbers and emails.
I've used products like Builtwith and Wappalyzer and neither compare to the level and organization of data within Datanyze. It's much more robust and easy to access. However, it isn't perfect and sometimes needs to be updated, or removed and re-installed simply for it to function
zoominfo has old contact info, a lot of the time i look at specific people and their companies aren't updated. I get intent emailed to me from zoominfo for job changes and it will be 6-12 months after someone changed jobs so the information is just not accurate enough. apollo only pulls headquarters info, never had an accurate cell number from it so i stopped using it pretty quickly during our eval
I prefer using it from the SalesNav page compared to Zoominfo - seems way more up to date
Allows me to massively scale my prospecting by keeping me in page and I don't have to look up and cross reference on other tools
While it has a smaller set of functionality that I can use it for relative to Zoominfo, the things that it does do I've always felt it did a better job
Really simple UI and doesn't prompt me to sign in every day which I appreciate.
