I've been on the site, https://network.hashtag.be, and clicked on the extension icon, because you have to log in to use the extension. But it's a paying site, you can request a free trial, and they'll get in touch with you, as they say. The purpose of the site is not clear to me, how long it'll take to them to contact me is not clear (they asked my phone number!), the price of the full service is not clear, and the deadline and the features available in the demo are not clear. Too many things are in the a fog. Be transparent with the users, you'll have more of them.
