For smaller-scale businesses that can't afford to have the best-in-class ecosystem (e.g. Hubspot, Salesloft, ZoomInfo, etc...), Apollo has all the fundamentals: enrichment, outbound prospecting, rudimentary deal and pipeline management. Review collected by and hosted on G2.com.
The platform seems like it was built by teenagers that have never used enterprise software or who have never done volume prospecting. It does a lot, but it does a lot in a half-baked almost-there way. They've clearly prioritized volume of features over refining things to a high quality level. I use Apollo because of this - it does a lot of stuff OK, and there aren't too many other vendors that have the same breadth. But every day there are things that drive me crazy. It's a junkyard of almost-finished products.
I have mixed reviews on support - when the live reps engage, I've had good experiences - one exchange actually turned into a minor feature request that they implemented in less than a week - that was pretty awesome. But I hate the AI support agent - it's not trained very well on the Apollo capabilities. I'm assuming that the teenagers haven't really built good documentation as a foundation.
