About
Proof
Proof is a social proof platform that shows recent purchase notifications, live visitor counts, and customer testimonials on your storefront to reduce purchase hesitation at the moment of decision. The psychological mechanism is well-established: seeing that other real people are buying or viewing a product reduces the perceived risk of purchasing. The implementation is a lightweight script and the no-code setup takes minutes. Proof works best on product pages and checkout flows where doubt is highest, and is most effective for stores with genuine transaction volume to display (a store doing five orders a day should not show a live ticker). For brands with consistent daily sales looking for a low-effort conversion lift, it is one of the easiest tools to justify on ROI.
Justuno
Justuno combines pop-ups, product recommendations, and upsell banners in a single platform with an AI personalisation layer that adapts what each visitor sees based on their behaviour and profile. The recommendation engine is the strongest feature: it surfaces relevant products at the right moment in the customer journey, which drives average order value without requiring manual merchandising rules. The pop-up builder is competent but not the most intuitive in the category. Justuno is better suited to brands that want a unified personalisation tool rather than separate point solutions for pop-ups and recommendations. For stores generating over $2M annually with enough SKU depth for recommendations to be meaningful, the AOV lift from the recommendation layer typically delivers strong ROI.
