Challenge: As a predominantly digital brand, Casper needed to update its commerce platform
to deliver a consistent yet personalized buying experience for shoppers across all channels. Casper’s ideal solution was to add Salesforce Commerce Cloud to its existing Salesforce suite. However, Salesforce Commerce Cloud was a new service for the company. A fast and seamless integration would require specialized knowledge and consultative support.
Solution: Without the needed technical expertise in house, Casper sought out Toptal to simplify the platform integration and help construct a headless architecture for omnichannel versatility. The new Salesforce Commerce Cloud solution delivers a unified commerce experience across all devices, with a flexible ecosystem for building customer-centric experiences.
Impact: Casper’s infrastructure design now powers a hassle-free shopping experience that feels natural and voluntary for the buyer.
