Though the over one-year-old startup’s cofounders and team are Indian, it’s headquartered in Delaware and is meant for the American market.

The company already has top oncologists from Memorial Sloan Kettering Cancer Center (MSK) and the American Institute of Cancer Research (AICR) on its board.

The fact that the company doesn’t yet have a solid business model hasn’t stopped venture capitalists from circling, either.
