Pulse has now been installed more than 5 million times by mobile users across all supported platforms, the startup also tells Mashable.
"Pulse is an instant-on experience without requiring registration," says co-founder Akshay Kothari. "5 million users have opened the app and started using it."
ESPN, for the first time ever (according to Pulse), will be syndicating its content to mobile by way of Pulse's apps for iPhone, iPad and Android. Coverage pushed to Pulse will include ESPN Headlines, MLB, NFL, NBA, WNBA and NCAA football and basketball news and analysis.
Pulse says it's taking the partnership as an opportunity to rework its Pulse Sports category. "The new Pulse Sports is broken down by sport, enabling you to customize your experience by season or by your favorite sport," Cristina Cordova, a member of Pulse's business development team, writes in a blog post on the news.
The addition of ESPN comes less than two weeks after Pulse inked partnerships with The Atlantic and The National Journal to beef up featured content in its news, politics, business and culture verticals.
