Proof helps you build instant credibility with your website visitors by showing them that other people are already buying and using your products. Instead of relying on static testimonials, you can display real-time notifications of recent signups, purchases, and active visitor counts. This creates a sense of urgency and trust that encourages new visitors to take action. You can easily install the software by adding a small pixel to your site and then customize how your notifications look to match your brand. The platform allows you to track how these alerts impact your conversion goals through a simple dashboard. It is designed for marketers and e-commerce store owners who want to turn more of their existing traffic into customers without increasing their ad spend.

The platform integrates directly with your existing tech stack to supercharge your performance marketing. By focusing on first-party data and identity resolution, you can decrease your reliance on third-party cookies and expensive retargeting ads. It is primarily designed for mid-market and enterprise e-commerce brands looking to maximize their owned-channel conversions and build long-term customer relationships.
