Practo, which has expanded to Singapore, the Philippines, Malaysia, and Indonesia, offers practice management software for doctors and hospitals and a doctor search app for general users. “What took us a year in India takes three months elsewhere because we apply the learning [from India],” says Shashank. He claims that 50,000 doctors pay between $200 and $2,000 annually for its software; hospitals pay upwards of $5,000. Revenue grew 10 times to Rs 29.7 crore in FY15. It is on course to enable app-based transactions (such as doctors’ fees), and expects to derive 40% of revenue from them.
