About Plum

Plum is an employee insurance and health benefits platform focused on making health insurance simple, accessible and inclusive for modern organizations. Healthcare in India is seeing a phenomenal shift with inflation in healthcare costs 3x that of general inflation. A majority of Indians are unable to afford health insurance on their own; and so as many as 600mn Indians will likely have to depend on employer-sponsored insurance.

Plum is on a mission to provide the highest quality insurance and healthcare to 10 million lives by FY2030, through companies that care. Plum is backed by Tiger Global and Peak XV Partners.
