Thanks! I haven't used Pulsar, but the general answer is that mentions.us is focussed on sending you alerts for notifications, whereas more sophisticated social listening tools provide a lot more analytics (e.g., sentiment analysis).

If your company just wants alerts when their keywords are mentioned on social media then mentions.us should work great for them. If you work for Coca Cola then you likely need something very different from your social listening tool!

Thanks for clarifying, we're a small org and so the few mentions we get could be analysed manually I'm sure. I will flag it to the marketing team!
