All-in-One Sales Solution, Needs Better Sequencing

|Apollo.io
I really like Apollo.io because it's very easy to use, especially the parallel and power dialer features. Since these features were added, our team has switched fully to the Apollo dialer, dropping our other dialers. It makes everything all in one place, so we can find our leads and call them right from the same website. It has also helped us consolidate our tools and processes into one platform, saving us time and money. Setting up Apollo was great and very easy too; we had everyone logged on quickly and got them their local presence and no phone numbers without any hassle since we already used it from the beginning.

Effortless Lead Generation with Seamless Campaigns

|Apollo.io
I really like Apollo.io for its simple way to get contacts to decision makers. The addition of contact scores, company websites, and other details is great. The ability to create sequenced campaigns and actions is a deal breaker for me. I find the onboarding process very simple and I appreciate the wide range of creating automated processes. The AI support in searching for contacts and personas is also a big plus, and I like the possibility to work in a team environment.
