Internet of things startup Notion is gaining support for its home monitoring sensors with a new $10 million round of venture capital to be announced Tuesday.

The Denver firm, which added insurer Liberty Mutual as an investor last year, said it is now working with “three of the top five home insurance providers,” but declined to name which ones.

Notion’s technology is built into round sensors that can be attached to doors, windows and home appliances. These sensors, which look like hockey pucks, can alert homeowners via mobile app or text when a door is suddenly opened, the washing machine is leaking or the temperature in a room is abnormally hot or cold.

“Insurance providers are rolling out Notion to policyholders to help them reduce losses, increase sales and decrease churn across their portfolio, and create more positive touch points with their customers,” said Brett Jurgens, Notion’s CEO and co-founder. “In exchange, policyholders are empowered to make more informed decisions around the safety and maintenance of their home, and are eligible to receive discounts on their monthly premiums for installing Notion.”

Notion is pursuing a category called “home telematics,” which would be similar to automobile telematics that are used to track a vehicle’s speed and could impact a customer’s insurance premiums. Home insurers could use smart home technology, like Notion’s, to price insurance differently as well.

“Ultimately Notion’s goal is to help homeowners protect what they love with products and services that change what the home is capable of doing — and over time, help insurance companies to offer more customized policies to their policyholders,” Jurgens said. “To get to this place of home telematics, you need a whole bunch of data — and that’s where Notion comes in.”

Investment in internet of things companies last year has more than doubled since 2013, according to a report by venture-capital researcher PitchBook. While the number of deals declined last year to 257, from the prior year’s 335, the amount grew 17 percent to $1.32 billion.

Notion, which has doubled its workforce to 20 in the past year, plans to use the new funding to expand its reach with current customers and new ones, as well as invest in the product and marketing efforts. The company expects to make critical hires in engineering, data science and marketing, plus hire for other jobs.

The new Series A round, which brings Notion’s total funding to $15 million since its launch in 2013, was led by Draper Nexus and TransLink Capital, two venture firms with significant ties to Asia. On its site, TransLink said its expertise is linking U.S. startups to strategic electronic and manufacturing partners in Asia. Mitch Kitamura, with Draper Nexus, and Toshi Otani, with TransLink, also join the Notion’s board.
