Ok, so I decided to try out this tool for less than the usual price of a Lifetime deal here at appsumo (< $49)
You can check out the actual widget on my website (mrdzyn.com)

What I like
🌮 You get unlimited participants (and unlimited campaigns for any website)
🌮 It's easy to get a campaign started (currently they only have 2 templates - Referral Program and Quick Referral. In this case I tried Quick Referral. Quick Referral rewards are at the moment limited to PROMO CODES (they target ecom owners) but you can choose FILE or LINK. You can select how many "rewards" to give away only after performing the tasks (choose one or all -- Share, Video (does not work when I tried, Survey, Newsletter (subscribe as an ambassador)). Choose Popup, Widget, and Integrations. I chose SURVEY for this demo before you get the "Reward"
🌮 integrates with all websites and ecom platforms (shopify, magento, woocommerce)
🌮 Statistics for all campaigns
🌮 Ambassadors listing

What needs to improve
🌮 I can still see the BRANDING on the footer (GIRAFI) -- I thought there was no BRANDING?!
🌮 Design for popups and widget needs to be improved further (more customizations)
🌮 integrations with other platforms (i.e. Sendfox, to send subscribers / ambassadors)
🌮 The "reward" link is not looking as good

Overall, I think this is a really good tool, wish them more success!

Cheers,
