Simplee is part of the growing fintech movement in healthcare and the $330 billion in annual out of pocket medical spend, a total that eclipses online retail spending.

'Many components of our healthcare system are ripe for transformation by technology-minded companies, and payments represents one of the biggest near-term opportunities,' said Ted Maidenberg, co-founder and partner at Social Capital. 'Patient payments are largely broken, and we're excited to expand our investment in Simplee as they bridge the consumer experience gap and set a new bar for how patients engage and pay in healthcare.'

'The patient financial experience is proving a brand differentiation source for healthcare providers in the rising consumer battle for patients,' said Simplee CEO and co-founder Tomer Shoval. 'We are thrilled to have support of investors like Social Capital and American Express Ventures as well as returning investors 83North and Heritage Group as we define the financial technology future of healthcare.'
