Google Ventures lead a $130 million Series B funding round on big data cancer treatment startup Flatiron. Launched in 2012, Flatiron tracks and aggregates a large number of cancer-patient data to help doctors make treatment decisions.

Google Ventures partner Dr. Krishna Yeshwant stated “Cancer will likely touch all of us at some point in our lifetimes, either as a patient or as the family or friend of a patient. Flatiron has pioneered a way to learn much more about cancer, so that we can improve the way we care for patients and treat the disease.”

“It’s rare to find a team of the calibre assembled by Flatiron Health that combines pragmatic insights from the healthcare industry with the deep technical insight of the IT industry. They are working on one of the biggest problems in healthcare, and their progress has been nothing short of stunning to date.”

First Round Capital and Laboratory Corporation of America also contributed to the Series B financing. It is believed that a large part of the money invested will go toward the acquisition Altos Solutions — an electronic health company that has over 1,300 clinicians using its medical data.  The web-based software offers a workflow that helps clinicians document different aspects of cancer patient care. Collectively its clients see more than 550,000 unique cancer patients each year. The plan is to integrate Flatiron’s OncologyCloud and Altos’ OncoEMR to improve data capture, data flow and improved decision support.
