Every unanswered phone call can cost a business a customer. While many companies accept this as part of everyday operations, Indian-origin entrepreneur Apurva Shrivastava saw it as a problem worth solving. Drawing on lessons he learnt while helping in his parents' small business, he co-founded Avoca, an AI startup that answers customer calls for home service companies. Today, the company is valued at $1 billion (around Rs 8,300 crore).
