Interest in artificial intelligence in healthcare soared in 2019 with investors pouring $4 billion into the sector across 367 deals, according to a new report.

That's up from nearly $2.7 billion invested in healthcare AI in 2018 across 264 deals, technology market intelligence company CB Insights reported last year.

In general, AI startups raised a record $26.6 billion in 2019 with a total of 2,235 investment deals, according to CB Insights' latest AI global funding report.

Healthcare led AI investment, topping the $2.2 billion raised by financial and insurance AI. Companies working on AI in retail and consumer packaged goods brought in $1.5 billion in 159 deals.

In the third quarter, healthcare AI companies raised almost $1.6 billion across 103 deals, CB Insights reported.

The surge in funding was led by mega-rounds of financing reaching at least $100 million. Babylon Health, a U.K.-based AI chatbot that also links up to provider practices, falls into this category and raised $550 million last year.
