NEW UNICORNS: Meet the 14 startups that grew to be worth billions in 2016

Founded: 2003

Valuation: $1 billion

What it does: The Chicago-based technology company provides software to help property managers supervise everything from electrical work to snow-plow contractors to landscaping. The "no-glamour" company allows property managers to keep tabs on multiple properties at once, and it's already signed on customers from Family Dollar to Colony Starwood Homes.

Founded: 2000

Valuation: $1 billion

What it does: ForeScout's technology helps companies monitor all of the devices that are connected to their network at any given time. For many large enterprises, the number of devices can easily run into the millions — things like PCs, employees' mobile devices, virtual machines used for testing new applications, and now IoT devices — which makes it it hard for network administrators to keep tabs on everything happening on their company's network. Forescout's CEO said that when the company first runs its software with a client, it typically finds 20-30% more devices on the network than the client's IT team expected.

Founded: 2012

Valuation: $1 billion

What it does: Cylance built a product that uses artificial intelligence to analyze a file you're about to open, determine if it's malware, and then stop it from executing — all in less than a second. It solves the problem of email phishing scams, which are still a favorite method of hackers, and has over 1,000 customers, it says. Cylance was founded by Stuart McClure and Ryan Permeh, two well-known names in security who are perhaps best known for their work at McAfee.

Founded: 2014

Valuation: $1.1 billion

What it does: Opendoor is betting that homeowners would take a guaranteed sale over a higher price. It calculates a fair market value and pays homeowners before re-selling the home with a 30-day satisfaction guarantee.

Founded: 2006

Valuation: $1 billion

What it does: Anaplan offers a financial-planning cloud app that's as easy to use as a spreadsheet, but also does things Excel can't do, like modeling and letting groups work together. A planner can use it to see how adding more employees might affect sales and profitability, for instance. Its claim to fame is that it's a lot less expensive than planning software from giant SAP.

Founded: 2013

Valuation: $1 billion

What it does: Carbon3D grabbed headlines and attention for its method of seemingly creating shapes out of a liquid resin soup. It's much more complicated than that, but Carbon3D has caught the eye of everyone from Ford to Johnson & Johnson. While Ford imagines a future of speedy customizable parts, like custom-designed cup holders, healthcare operators are looking at Carbon3D for a fast way to create surgical parts. The machines are already being tested less than a year after they launched. In April, it released its M1 printer.

Founded: 2011

Valuation: $1 billion

What it does: Gusto offers cloud payroll, insurance, and HR software for small businesses. It was co-founded by Josh Reeves, who says the company now supports 40,000 customers.

Founded: 2012

Valuation: $1.2 billion

What it does: Flatiron Health is a software company that organizes the world’s oncology information and makes it accessible for doctors, patients, and researchers.

Founded: 2011

Valuation: $1.29 billion

What it does: OfferUp is making waves as a mobile-only hybrid between Craigslist and eBay. The company is said to have surpassed the early days of eBay in terms of sales volume, and its users are spending the same amount of time on OfferUp in a day as they do on Snapchat or Instagram.

Founded: 2014

Valuation: $1.55 billion

What it does: Despite remaining in stealth, Zoox has already raised $290 million for its unseen product. The only hint founder Tim Kentley-Klay has given was at a conference in October, when he described it as "Disneyland on the streets":

“At Zoox what we’re creating...is not a self-driving car any more than the automobile is a horseless carriage. We’re not building a robo-taxi service, we’re actually creating an advanced mobility service,” Kentley-Klay said, according to the Wall Street Journal. “You can really think of it as Disneyland on the streets of perhaps San Francisco, and that means a vehicle which is smart enough to understand its environment but it’s also importantly smart enough to understand you, where you need to be, what you want to do in the vehicle, and how you want to move around the city.”

Founded: 2012

Valuation: $1.6 billion

What it does: Self-driving car startups aren't the only billion-dollar bets around. Quanergy isn't building its own car, but instead specializes in building LiDAR systems — the 3D sensing systems that self-driving cars use to the see the world. Already the startup has struck partnerships with vehicle-makers including Mercedes-Benz and Hyundai.

Founded: 2012

It takes a company's data from virtually any source like Twitter, Facebook, Salesforce, corporate databases, spreadsheets, and over 300 other applications, and turns the data into charts and graphs. If a sales rep wants to see how many likes a post got on Facebook from a certain territory in Nebraska, Domo boasts that it's the place.
