Walnut

Walnut helps you transform static product tours into interactive, high-converting experiences. Instead of relying on recorded videos or unstable staging environments, you can capture your product's front-end and create a perfect, clickable sandbox. This allows your sales team to deliver consistent, bug-free demonstrations every time while tailoring the experience to each prospect's specific pain points.

You can also embed these interactive demos directly on your website to generate qualified leads or send them as leave-behind collateral after a call. The platform provides deep analytics into how prospects engage with your demo, showing you exactly which features they care about most. It effectively bridges the gap between marketing interest and sales conversion by letting prospects experience your value firsthand.
