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.

Sales automation is the most suited use case of Clay. You could generate GTM motions that are auto triggered by the signals, so you could actually create workflows that are triggered on specific signals. For example, a company gets new funding, you can reach out to the company within in a matter of minutes and you can track a lot of news that's happening on Google or using RSS feeds. You can patch that news into Clay and then manipulate that and get insights out of it. The second best use case is the data enrichment or data cleanup. Usually companies have CRMs with messy data. You can import that. Clay has native integrations with Salesforce, HubSpot, Pipedrive, Marketo, and you can import those lists into Clay and then clean the data, enrich the data, and then push that forward, update the data in the CRMs. That's the second best use case that I use it for and would recommend it for.

RainKing is less appropriate when you don't have the funds or resources to pay for it. You could easily Google the information that you're looking for, or use CrunchBase, but it's extremely time-consuming. RainKing makes this very easy and the data seamlessly sends to Salesforce with the proper integration. RainKing is very appropriate when you have a large team of folks that need to source leads/accounts simultaneously and need licenses to do so - it's worth the money with a larger team.

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

  • Pros, I think there are a lot of pros, so I mentioned a couple of them already, so being able to use different data providers. I think being able to massage the data, I call it a data orchestration where I can get different points of inputs of data. I can throw everything in Clay and then I can make all the changes before I use them for campaigns, for email, for LinkedIn, for whatever reason I'm going to use my data, but it's really easy to enrich, it's really easy to do research. It's really easy to build agents that tie to each row in your dataset, like there are a lot of things that you could use it for that are huge pros.

  • Being able to search for companies that are currently evaluating solutions in your space.
  • The contact information for people and related people is also great, I have used dozens of other data solutions and prefer Rainking.
  • Rainking also gives you the ability to create lists of your ideal buyer and download them which was great for my team and I pull new contacts to prospect!
  • I can't get over how impressive the org chart info is in RainKing, it allowed myself and my team to find other involved prospects and get a good feel for organizations.

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

  • A max column limit. I run into the column limit all the time and kind of have to figure out using multiple tables. Just bugs really. I mean if you start getting too crazy on it, I feel like takes a long time. You can't really identify that it's working or if it's not. So that kind of slows things down a little bit.

  • Account manager - really unresponsive, not interested in helping with renewal, making the case to our execs
  • The Discover/RainKing team was not interested in helping us expand the way we are utilizing the tool, provide additional training, etc
  • Contacts department designation lacks in accuracy, we frequently found significant mismatches

I think it's actually before the launches today, I would say eight, but after they launch, what's the name of the product? I dunno if it was the web intent or the sculpture. 10, because I think that the sculpture was the missing part of plates till now.

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.

So in a sense, there is a large community, and because of the community you also learn multiple workflows and how to use it better. You can kind of democratize or source knowledge more easily on how to use the product, and also transfer it so other people can use it more easily. So in a sense, that works.

I've used SalesNavigator and Zoom Info. I actually think that Ranking is a great solution if you can use it in tandem with SalesNavigator. When it comes to pulling lists, in my opinion, Ranking does it best. Now that it has the database combined with Discoverorg, it's even more powerful to use.

Return on Investment

  • Without Clay we would probably have our agency, but not with the level of sophistication we have right now or really one of our USP that we are certified by Clay. That's how we get a lot of inbound leads as well. So that of course leads to a very healthy ROI. If we look at inbound.
  • I think negative as terms in negative ROI, I think this is a nice one to touch on. Expectation management for tooling such as Clay is extremely difficult because people see a lot of stuff happening on LinkedIn from the top 1% of Clay experts and they look at us and "hey, we want the same thing," basically. That's quite a challenge. So that's really a good conversation to have with your potential client as well. Like, "Hey, I know, tell me what you've seen. We're going to see what we can do if that's reasonable or not." Set realistic expectations there and don't expect to go from zero to 100 within a very small time window. So that was something we had to learn. We had a lot of unrealistic expectations for what we can do. We can improve your business, but we can't do it with a factor of X or in a period of eight weeks.

  • I don't have that information readily available to quantify the positive impact. However, I will say that I've found a lot of good prospects via RainKing to target my outreach efforts to. I definitely feel like the product pays for itself.
