We’re well positioned to make the lives of digital workers better by elevating work to the outcomes that matter.” Currently PagerDuty users include the likes of GE, Capital One, IBM, Spotify and virtually every other software company you’ve ever heard of. Earlier this year, for example, the company announced its new AIOps services that aim to help businesses reduce the amount of noisy and unnecessary alerts.
