These billion-dollar startups more than doubled their value in 2015

There are more than 145 companies worth more than a billion dollars in Silicon Valley.

Of those, 19 more than doubled their value in the last year.

Venture capital database CB Insights tracked the list of the biggest unicorn valuation increases of the year. (Unicorn is Valley parlance for a company worth more than a billion dollars).

Here’s a list of companies that more than doubled their value in the past year, courtesy of CB Insights:

The startup that's trying to shake up the insurance industry has been a favourite of 2015. Google invested $32.5 million in Oscar in September, bumping it to a $1.75 billion valuation.

Doubling its valuation was 'conservative,' the CEO of SaaS startup Sprinklr told The Wall Street Journal. In March, it closed a new round of funding that put it into the unicorn club. The company helps brands like McDonalds manage their thousands of social media accounts by logging into Sprinklr, rather than each Facebook, Instagram, or Twitter account individually.

Before it faced shutdowns in multiple states, Fanduel rode the fantasy sports wave all the way to the bank for a $1 billion valuation.

Slack, the popular workplace chat app, raised $120 million last October at a $1.12 billion valuation. Six months later, it raised another $160 million at a $2.8 billion valuation. It doesn't need that much money, explains Fortune's Dan Primack, but it's happy to raise money when it's easy and brace for a downturn should it come in 2016.

The London-based peer-to-peer money transfer service raised $58 million from Andreessen Horowitz in January.

For too long legacy providers' dominance of the market has allowed consumers to be hoodwinked into paying huge hidden charges for services as basic as currency exchange.'
