Navneet Singh used to work a six-day week and spending two hours of his only day off at the grocery store wasn’t the most appealing idea. “I wanted to spend that time with family,” says the co-founder of Peppertap, an online grocery start-up. He started the firm in November 2014, and the app raised $10 million from Saif Partners and Sequoia Capital in April 2015. It offers more than 15,000 SKUs across staple foods, dairy products, household items, fresh fruits and vegetables.
