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.
SellHack is great for anyone who is in sales or whose work requires the need to build lists or to search for missing email addresses. Many businesses and social media sites provide email addresses, but of course depending upon industry many do not, so SellHack is my go to tool when I absolutely have to find an email.
Often I'll be searching for an email address, so I'll go to LinkedIn, ZoomInfo, Sales Navigator. These are all services the my firm pays for me. But inevitably I will need another sure fire source and SellHack is my go to tool, it will find email addresses often when I can't find them anywhere else.
I use Hunter also, but many times I found addresses on SellHack that I couldn't find on Hunter.
I love that you can subscribe and purchase various levels of searches per month, or if you want you can buy x amount of searches that don't expire.
SellHack has a nice Chrome extension that stays on top so when I'm searching I can click on it from the pull down and enter the data and copy/paste the results into my CRM.
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.
I wish they had a roll over feature for unused credits on the subscription.
SellHack is great for list building, and export to popular CRMs like Salesforce.
If you have an email address and you're not sure if it's accurate, SellHack will verify the address and give you a percentage rating on their confidence that the address works (a percentage rating is given for all email searches).
I love their referral program: Give 50, Get 50: Refer a friend and you both get 50 free credits! I've used this many times.
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
Hunter and ZoomInfo are two services that I also use to find email addresses. Generally if I can't find it on one of those SellHack will find it for me, never the other way around. I use them all, but SellHack is my secret weapon.
It's been vital. I've made too many contacts to mention because I was able to source the correct email address for C-suite executives (which are my target prospects).
The cost of the service has been affordable. I work inside sales and so I have to be selective on which tools I pay for because the ROI must fit within my budget. I've used SellHack since day one in this role and I use it every month.
