There are always people who are out of touch with the current market (and I don't mean that condescendingly. There's not much value in knowing these things for many people in the space). That doesn't mean things they aren't aware of aren't well known. Of course not everyone knows, but a critical mass certainly does such that it's not really necessary to introduce the company every time it's discussed.

> Absolutely not. In 20 years I've heard the name twice: Once six weeks ago when they emailed me to try to get my team to use their tools (which they failed to describe to me, so I declined), and a second time just now on HN.

I want to second this - today is the second time I heard of them. The first was a job offer on LinkedIn that also failed to describe what Datadog did. It did talk a lot about how it was enterprise scale and important, though.

I declined to look further into it.

...I'm really struggling to understand why you can't/won't figure out what DataDog does the same way any of us figures out what anything does; by Googling it.

You asked your coworkers! That demonstrates an interest, why wouldn't you ask Google?

Well, it was only founded in 2010. So it's been less than 12 years in existence.

And one of the better known vendors in monitoring services.
