Cloud-based HR solutions firm Darwinbox has raised $15 million in fresh funding led by Sequoia Capital, as the company gears up to expand services beyond India into Southeast Asia. Existing investors Lightspeed Ventures, 3one4 Capital and Endiya Partners also participated in the Series B fundraising.
