Apollo.io

Web-based

Founder

Really good software if you are looking for leads, in my opinion, it's the best software of its kind.

Senior Data Analyst

The Apollo team's customer support was also something I truly appreciated. They attended to my needs with great care and were quite helpful.

Managing Partner

Apollo.io Contact Validity & Reliability has been Excellent - it supports various filters & social media integration (LinkedIn), which is essential when we cross-reference the contacts.

Director

Easy to use, great filters, fast, powerful. I loved the fact that you can insert personalised fields on emails.

Ease of use and integration. I am happy to use it daily as a great datamining tool.

Excellent platform, great support and advanced features and functionality.

Great product if you're looking for a better way to prospect leads with more granularity & find their emails.

Managing Director

Apollo is very easy to use and provides great information on my prospects.

B2B Marketing

However, after we purchased, I realized that even though they had that "company" when I needed it, a LOT of those companies didn't have any contacts at them so they were worthless to me.

Freelance Content Writer

Recently, my senior at work recommended me Apollo and I fell in love with it since day one.

I love the user interface and ease of use. I AM ABLE TO GET NEARLY 100's of leads every day.

Sales

I love this product and would highly recommend it to anyone with a small sales team and limited budget.

Account Manager

My job is very easy to prospect as a result, and I don't waste my time or other people's time because I know before emailing or calling enough about the company that I know if it is worth pursuing.

No Zapier Integration, so was hard to try to sync up email prospecting in Apollo with the leads I had in my Close CRM without doing some manual work.

The customer service is amazing. Personally met with the [SENSITIVE CONTENT] but their hands-on approach is needed to perfect the system.

Marketing Manager

And the company filters are almost endless: revenue, number of employees, software they use, and many more. That is highly useful in finding very qualified leads, with just a few clicks.

There is no telling when they could place another limit for 1000 or 100 without any prior notice to their current users.

Integration with some of our existing systems could be difficult. That might have been partially due to them being legacy systems.

Seamless.AI

Great experience, and very useful tool. With all the movement in the market lately, I was very impressed with how up to date the info was as i see contacts moving within my industry.

I would say the biggest strength to seamless is going to be the speed at which you could build list off of LinkedIn. The tool is super fast, and that's a huge help when you're scraping big list.

BDM-Cloud Services

They are great and very helpful. SENSITIVE CONTENT] is the best when it comes to wanting his customers to see immediate success using the Seamless tool.

Executive Assistant

The one thing that I found to be the worst is the breakdown of leads by location - for us it's specifically NY - they are missing many counties in their parameters.

Healthcare Solution Specialist

I was super pleased with the support after the purchase. Asked for and immediately received 1 on 1 coaching session.

Enablement

Deceptive sales process. Was not informed of the mandatory 60 day notice to cancel services.

VP of Sales and Marketing

The cost/benefit of this tool is one of its standout attributes. The data accuracy is as good if not better than all the other competitors I have used.

Account Executive

Excellent customer service and assistance. The onboarding was great, and the follow-up really helped.

Seamless ai has one of the best sourcing systems I've ever seen. I cant do my job successfully without it.

Social Media Manager

This thing is really cool and super intuitive. Mostly I love how much time it saves on prospecting.

Sales Operations Manager

The data looks pretty accurate, customer service has been great. I like how much refinement I am able to input to find exactly who I am looking for.

The integration with Sales Navigator is amazing and makes it SO easy to find contacts and import into a CRM.

Director of Partnerships

Limits on the number of contacts per day can be frustrating.

Incredibly easy to use and generated hundreds of emails, phones in minutes versus weeks. Also - awesome integration with LinkedIn Navigator, Google, CRM (I use Salesforce).

Inside Sales

Good Quality Data, Easy to access and navigate.

Relationship Manager

It's rare when it happens, but some contact information is duplicated, or there are missing phone numbers and I have to check the website for the right person, phone number or email address.

Business Development Rep

The ease of use in getting prospect information and how it's integrated with linkedin sales navigator.

AI has been a game changer for our outbound strategy at Zero Cost Advantage.
