"Great product and team"

Quick to implement, very responsive and solution oriented team. We had been looking for a solution like this for a while and StackOne stand out for ease of use, incl. documentation, and overall functionality. We managed to set-up and run a successful POC within 1 week, confirming compatibility with our platform and key functionality. Review collected by and hosted on G2.com.

What do you dislike about StackOne?

So far nothing, hoping to see the number of connectors expand quickly the coming year(s). Review collected by and hosted on G2.com.

I don't have a specific dislike, but one thing we discussed on the last call that had already been addressed is more insight into the priority of integrations on their side. Review collected by and hosted on G2.com.

"Great API aggregation platform with incredible support"
What do you like best about StackOne?

The API is very sane and I don't need to care about peculiarities of all the HRIS and ATS APIs. The support is wonderful. Most times, you get all the help you need in a couple of days. The new UI to debug request is also great. Review collected by and hosted on G2.com.

What do you dislike about StackOne?

Breakages in the API do happen every so often. This is expected as StackOne aggregates a ton of third-party APIs but it's still a nuisance. Review collected by and hosted on G2.com.

"Fantastic, supportive team with very capable technology"
What do you like best about StackOne?

Integrating with StackOne has been remarkably smooth and efficient. Their API documentation is excellent, and the StackOne Hub is intuitive and user-friendly. The implementation team has been highly responsive and supportive, consistently helping us enhance our solution. Review collected by and hosted on G2.com.

What do you dislike about StackOne?

Nothing specific comes to mind. In the past, it was sometimes challenging to determine which endpoints were available in each ATS. However, with the launch of a new dashboard, this process has become much easier, making it a seamless experience! Review collected by and hosted on G2.com.

Because it connects multiple platforms, sometimes there are still integration issues which can take time to resolve, but this is more an issue of the industry rather than StackOne as a company. Review collected by and hosted on G2.com.
