Consider not marketing yourself as an X alternative when launching? That might fly in slide decks and investor meetings. But I don't know what Datadog is, and I certainly don't care, won't look into what DataDog is just so I can be qualified to learn about your product.
I guess it may be the case that you really know who your target is, but why miss the majority of the market and position yourself as pepsi on the same stroke?
Datadog is industry standard at this point, if you dont know what splunk or datadog is you are likely not their ICP and their marketing is not targeting you.
Even if it won't work for everyone — some people (including me) are looking for Datadog alternatives, so this is the easiest way for them to speak to their ICP.
