"Ocean.io’s High Success Rate for Direct Phone Numbers"

5/5

What do you like best about Ocean.io?

I’ve been using Ocean.io for a long time in my recruitment work, mainly to find direct phone numbers of candidates and decision makers in the Netherlands. The biggest reason I keep coming back is the success rate on phone numbers. Review collected by and hosted on G2.com.

What do you dislike about Ocean.io?

The API doesn’t return contact details directly, only through a webhook, so you have to build and maintain your own setup just to receive the results. Review collected by and hosted on G2.com.

What problems is Ocean.io solving and how is that benefiting you?

Ocean.io helps me find direct contact details, especially mobile numbers, of candidates and decision makers that are hard to reach through other channels. In recruitment, a direct phone call is often the fastest way to start a conversation, and Ocean.io saves me a lot of time searching for that information manually. Because the results come back with a clear status, I can quickly see which contacts are worth following up on. This lets me reach the right people faster and spend more of my time on actual conversations instead of searching. Review collected by and hosted on G2.com.
