Investment in artificial intelligence companies has soared, with healthcare AI companies raising $864 million in the second quarter of 2019, according to CB Insights.

Among them, healthcare startup Viz.ai, which is using AI to help medical professionals spot early signs of stroke. The company's platform has attracted interest from investors, and it recently scored $50 million in series B funding. The funding round was led by Greenoaks with participation from Threshold Ventures and CRV along with existing investors GV, formerly Google Ventures, and Kleiner Perkins.

Viz.ai uses deep learning algorithms to identify a suspected large vessel occlusion, a particularly disabling type of stroke, in a CT scan and alerts the stroke team specialist. By alerting the right doctor at the right time and synchronizing care, Viz.ai has the potential to significantly reduce the time to treatment and greatly increase a patient’s chances of a good outcome, according to the company.
