Chose Apollo.io
I just did the trial so this question in not relevant.
Chose Apollo.io
Apollo is much cheaper compared to the others. The filter options are much better in Apollo.
Chose Apollo.io
So we have evaluated Seamless AI, Enrich AI, and Snov.io before finally deciding to settle for Apollo. These platforms have better UI and some, like Snov, have good email sending capability, but they all lag when it comes to their database; they do not match up to Apollo. …
Chose Apollo.io
because it does the work of an outbound/outreach platform, as well as a prospecting platform – all in the same place.
Chose Apollo.io
Seamless's API access requires a minimum 10K annual spend so it was out of reach based on my budget
Chose Apollo.io
As there are more credits in Apollo and it is user-friendly than the others. And mostly, I liked the accuracy of the data it provided, which is generally accurate and directed to the right person, primarily used in B2B sales from the user's perspective. I prefer this …
Chose Apollo.io
Honestly, all of the above do something or other quite well. There are three main reasons we have stuck with Apollo.io, namely: Apollo.io seems to have the most trustworthy data about companies, as we have checked their records at times; Apollo.io seems to just have the latest …
Chose Apollo.io
After reviewing it the data Apollo.io provides is more accurate than almost all other tools, versus zoominfo who is the main competitor the data might be a little bit better on zoominfo however the automation tools makes it the best choice for a startup like us, we needed a …
Chose Apollo.io
Apollo is inexpensive of all the above tools. Data accuracy of other tools like lintel and infotelligent is much much better but they are expensive also. One needs to be careful while using data from Apollo because email bounces can damage your domain reputation. I suggest you …
Chose Apollo.io
It was chosen before I arrived at the company. Either way, Apollo is the best available tool on the market based on the features and services it provides.

There is a lot of room for improvement in the UI as it is not as intuitive to manage as it seems initially.

Chose Seamless
Seamless is easier to use than both of these and provides much more accurate contact information. You can also set up an advanced search to prospect much more effectively than Apollo.io and LinkedIn Sales Navigator. It has a much better UI and actually has customer support, …
Chose Seamless
There are many differentiators; the best can be INTENT data. Seamless.ai's Intent data is very strong and accurate. This helps in prioritizing hot leads through signals and track when prospects change roles which can also help in timely engagements with these leads. It is also …

Apollo.io
Apollo.io played big role for us in saving $$$ by bringing data mining, AI Email Writing and acting as CRM altogether...for small to medium organization they can surely rely on Apollo.io...and it is doing things mostly right with some room for improvement for sure. Sales and Marketing team saves time in getting their emails drafted based on prompts, list of contacts they can fetch in minutes of time, earlier we used to have seperate tool just to mine data, then we used to upload the CSV file to email marketing tool, then we used to draft email...for all these process we were using three different tools - Apollo.io brought everything under one umbrella.

For small businesses that don't have big budgets for marketing automation, VisiStat is an ideal first step. For companies that have sophisticated systems in place, VisiStat will augment your analytics and provide a deeper dive into your website activity. Since the implementation involves adding javascript to your site, the user should be familiar with how to do this

Seamless AI is very well suited for the first round of prospecting, or when going after a very publicly known and traded company. A good example would be popular brand names in the country. Whereas it does show limitations for smaller companies, it cannot yield deep data in the same way as others might. However, it is agile, very fast, and compatible. I highly recommend it to any sales force.

Pros
Apollo.io
  • Firstly, finding the details of the potential customers that is there name, designation email and phone number since these are the most important cases most of the times I can get this data in Apollo.io
  • I can pull the bulk data of the targeted organization, or I can pull the emails based on the location and job titles
  • Apart from the email capture, the thing which helpful is that the email sequence can find emails and send emails in Apollo.io itself and also the report and the dashboard are so clean
  • Friendly UI and UX Apollo.io was the first tool which I used. Since then I'm still using Apollo.io for easy understanding

  • De-anonymizes website activity at the account (company) level.
  • Identifies net new target accounts.
  • Displays click path, time on page, time per session, and engagement level of each de-anonymized website visit.
  • Gives great daily insight on watchlists you've set up.
  • Delivers every possible de-anonymized visit with little filtering for accuracy.
  • More on the watchlists. I really love that you can receive immediate alerts on website visits from accounts you've listed on your watchlists. This way, you never miss the window of opportunity to reach out to your key targets while they are currently on your site.
  • Salesforce integration is good. KickFire pushes most recent website visits, pages visited, website click path, activity percent change, and more to the given account in Salesforce. You can then create reports and run them regularly to see which accounts are surging in website activity. This is also great for account prospecting, and for planning your sales outreach plan of attack. You can see which bits of your website content are most interesting to the company, and which products they are most interested in.

  • Refresh Rate of Seamless.ai is quite good. A quick way to know this is see if a lead has changed jobs recently on LinkedIn, how quickly does it get refreshed in Seamless
  • Search Capabilities are decent. Not as strong as some of its competitors, but would do the job for sure.
  • Exporting lead lists is a great feature and a boon for saving a lot of time. Direct CSVs can be exported and fed into the CRM.

Cons
Apollo.io
  • There are certain features about prospecting that require updates. For example, if people switch organisations, it should be automatically requesting the new email or new contact data for a particular contact in order to be updated in the system
  • The lead databases that are created if their new addition should automatically be updated in the list that I created with Apollo.io

  • Enrichment / Data Quality: Phone Number quality can be way better than it is right now. Even email addresses are incorrect a lot of times.
  • Industry Filter: There are just way too many industries. Some of them definitely can be grouped / combined to help land at search results faster.

The team wants to solve probelms, but we are finding that they don't know how to solve the more technical issues quickly. I suspect that they don't have a mature process for escalations, and they don't have a usable knowledge base article repository. They seems to push emails around to let us know that people are working on the issues to find solutions, but this takes weeks and oftentimes still leaves us without a resolution.

All of these platforms are good and offer valuable tools, but where Apollo.io is different is how this one platform does the job of several different ones. It is nice not having to use multiple platforms to get things done and makes integration and analytics issues occur less often. It is user friendly and constantly working to improve.

I covered this pretty extensively in the cons. The key differentiator here is that KickFire serves up almost all the data (or so it seems) to the end client. The client then has to do their own work on interpreting it. This is good because it means we don't miss out on any website activities, but it's bad because we get a lot of false positives. 6sense uses the confidence score approach I mentioned in the Cons section, which means the match rates of the data we get are much higher. Our experience with Clearbit comes from other tools that are built on it (Bombora, Drift, etc.), and it has not been great. We've seen many more inaccuracies with Clearbit.
