Angi (formerly Angie’s List) is an American home services website owned by Angi Inc., a subsidiary of IAC. Founded in 1995, Angi allows users to search for contractors for home improvement work. The platform's value heavily relies on customer reviews. Despite actively seeking reviews, only a small percentage of users provided them. To address this, Angi made 20,000 calls monthly to previous users, asking them to write reviews. However, this resulted in merely a 5% response rate, necessitating a more effective strategy.
