Ana’s first meeting with Elizabeth was at Coupa Café, a hip coffee and sandwich place in Palo Alto that had become her favorite haunt outside the office. After filling her in on her background and her travels to Asia, Elizabeth told Ana she envisioned building a disease map of each person through Theranos’s blood tests. The company would then be able to reverse engineer illnesses like cancer with mathematical models that would crunch the blood data and predict the evolution of tumors.
