COMPARE:
Apollo or ZoomInfo for a B2B contact database
A straight comparison of Apollo and ZoomInfo for buying a contact database for outbound, answered on the same seven dimensions as every other compare page here. Mamba Labs builds the Apify actors here, People Finder included, and the page says where it is the wrong answer.
The verdict
ZoomInfo is the bigger, cleaner database on an annual contract. Apollo is the good enough database with a sequencer, on a credit card. Most teams under twenty reps do not need what ZoomInfo charges for.
The same questions, both tools
| Apollo | ZoomInfo | People Finder | |
|---|---|---|---|
| What it actually does | Finds contacts in its own database, then emails them from the same account. | Gives a sales team a searchable database of companies and people, with intent signals layered on top. | Takes a domain and a role filter and returns named people with verified work emails. |
| Coverage and hit rate | A very large contact database, and a sequencer good enough that most users never add a second one. | The deepest United States coverage of any database here, including direct dials at scale. | As many people per company as the public record supports, rather than one lookup at a time. |
| What it costs | Per seat per month, with export credits as the real ceiling on how much data you get out. | An annual contract negotiated per seat, with export credits capped inside it. There is no self serve tier. | Cents per returned person, and an empty company is not billed as a result. |
| How it fits a workflow | Search, save a list, sequence it, all in one interface. Its API and CRM syncs are the weaker half. | Native CRM sync, a browser extension, and a data share that writes into a warehouse. | One call per company from Clay or from a script, and the rows come back ready to send to. |
| Where the data comes from | A contributed database, refreshed from user activity, so accuracy varies sharply by market and seniority. | A licensed and contributed database, refreshed by a research team and by user contribution. | The public web and the company's own pages, with verification run before the row is returned. |
| What it takes to set up | An hour to a first sequence. It is the fastest of these to something running. | Weeks. There is a sales cycle, a contract and an onboarding before anyone searches anything. | Pass a domain and the roles you want. There is nothing else to configure. |
| Where it stops | Coverage outside the United States thins out, and its data is the same data your competitors bought. | You cannot try it, you cannot leave it mid term, and the seat count is what you are really buying. | It works from a company. Handed a single name with no company it has nothing to search. |
The same seven questions are asked on every compare page here, in this order, so two of these pages can be read against each other.
Where each one genuinely wins
- Apollo wins on how it fits a workflow, what it takes to set up. A contact database with a sequencer bolted on, sold as one seat.
- ZoomInfo wins on coverage and hit rate, where the data comes from. The enterprise contact database, sold on an annual contract with a seat count.
- People Finder wins on what it costs. Finds the people at a company and verifies their addresses in the same run.
- Nobody wins on what it actually does, where it stops. Apollo and ZoomInfo give the same answer on those, and we are not going to invent a difference.
Try them yourself
What is best for you
Apollo is where almost everyone should start. It costs a fraction of ZoomInfo, it is self serve, and its sequencer means one tool instead of two. ZoomInfo is the right buy when the targets are enterprise, when direct dials and org charts matter, and when the budget owner wants a contract with a support team behind it. Its data is better on senior people at large companies and no better on the small companies most outbound actually targets. Check your own market before paying for the difference.
