Show IH: Free tool to turn "Join Now" into "Join 4500 IndieHackers"

I'm launching OnVoard Pulse at ProductHunt today. Pulse is a free tool that allows to turn ordinary-looking call-to-action (CTA) like "Join Now" into something like "Join 4500 IndieHackers".

How it works is that you can use Pulse to connect to major platforms like Mailchimp, Shopify and fetch social proof stats. From there, you can use our Site Modifier script to add a transformation layer on top of your site and create a strong CTA.

This works especially well when you are using lead-capturing forms with vendors like OptinMonster, Privy, and Sumo since all of them don't have ways for specify dynamic variables (like number of subscribers) when you are creating your form.

I think this can be incredibly useful - what do you folks think?
