StackOne is a game-changer – we launched 6 enterprise HRIS integrations in a few weeks. It is the only platform we tested that enabled us to customize the unified API to fit our use-case across so many integrations. And the real-time API makes reading and writing much easier than other tools that have a sync delay.

StackOne has made launching new integrations much faster, and it only took a few days to implement. The documentation and support are amazing, and I’m impressed by how quickly the team are building new features!

StackOne powers the majority of Screenloop’s ATS integrations. It’s the best platform to support reading and writing a high number of data points across a lot of integrations. Our time to release a new integration dropped significantly and there is no data stored on their end. And the support is awesome!

The experience with StackOne has been phenomenal. The product is easy to use for our technical team, the support is world-class and the team is incredibly responsive to our growing needs. I’m delighted that we bet on them for such a critical part of our infrastructure.

StackOne has become a crucial part of our integration strategy. We wanted to augment our existing optimization integrations with a new hub that gives us broader reach and puts us at the core of our enterprise customers' content workflows without the pain of building them all in-house.

CTO, Phrasee
We’ve seen major improvements in data quality since we migrated to StackOne from another integration platform that was not real time (since StackOne always reads from the source of truth). The transition was super easy thanks to the support from the StackOne team!
