APIs from Xignite are helping four Finovate alums bring their technologies to the Apple Watch.

Betterment, Motif Investing, Personal Capital, and SigFig all have taken advantage of Xignite APIs to provide their Apple Watch-wearing customers with tools to help them stay on top of their investments and finances. The features enabled by the APIs range from real-time news alerts on stocks and the ability to place live stock trades, to monitoring spending and conducting portfolio maintenance.

Personal Capital CTO Fritz Robbins called Xignite’s APIs a “key piece” in its ability to provide its customers with timely, accurate information. Xignite CEO Stephane Dubois added that his company’s cloud platform was uniquely positioned to serve the “billions of devices coming online every day.”

Xignite CEO and founder Stephane Dubois demonstrated FactSet Fundamentals API at FinovateEurope 2015 in London.

“We are proud to be enabling these firms to make this leap into different technological ventures with our comprehensive and unique delivery of market data through our APIs,” Dubois said.

A leading provider of market-data cloud-solutions, Xignite’s reputation as the data provider behind fintech’s most dramatic disruptors is well earned. Earlier this month, CNBC took a look at some of Xignite’s clients, putting six of them (including five Finovate alums) on its CNBC Disruptor 50 list. Among the winners of the Benzinga Fintech Awards in April, 17 of the nominees and 11 of the winners used Xignite’s cloud-based financial market data (on its own, Xignite won “Best in Show” runner-up.) Recent partnerships with BMO Financial Group, ChartIQ, and MSCI this spring have helped Xignite significantly expand the range and variety of market data it can provide to its clients.

Xignite demoed its FactSet Fundamentals API at FinovateEurope 2015 in London, and participated in the inaugural FinDEVr event in San Francisco in the fall of 2014. Founded in 2006, Xignite is located in San Mateo, California.
