Silicon Valley’s largest tech accelerator is funding an experiment in crowdfunded healthcare. Watsi is a nonprofit that has brought healthcare to more than 11,000 people in 24 countries through nearly 22,000 online donations. It is estimated that 20-40 percent of all health spending gets wasted. But Watsi’s crowdfunding model makes transparency a top priority. When a family visits a hospital and can’t afford to pay for the necessary care, they can put their case on the Watsi site. Watsi’s donors will then have the opportunity to make online donations straight to the patient. Funds will be transferred to the hospital’s bank account and directly fund the patient’s treatment.
