As Vice President of Growth at Mention, Guillaume Cabane sought to enhance both the quantity and quality of signups by leveraging the Clearbit Enrichment API, resulting in a significant 54% increase in signup conversions. This API allowed for the automatic population of signup forms using just an email address, reducing user drop-off rates and improving user experience. Beyond increasing signups, the integration also enriched the data collected during the signup process, enabling more effective lead qualification by providing detailed information about new users, such as company size and funding. This allowed the sales team to prioritize high-value leads more efficiently and move away from manually searching for promising signups. The implementation of this API provided a seamless, automated solution for improving both customer acquisition and lead quality.
