Dev Heroku developers get push messaging abilities with new Urban Airship app April 24, 2013 6:00 AM Sean Ludwig Smartphone notification startup Urban Airship has launched a new app in the add-on marketplace of platform-as-a-service provider Heroku, a move to give PaaS developers better access to push messaging solutions. Heroku’s add-on marketplace allows developers to add more capabilities to their app development kits with a single click. At the end of 2012, the add-on marketplace had attracted more than 4 million installs. Big companies that offer add-on apps include Amazon RDS, Cloudant, New Relic, SendGrid, and Zencoder. Now Urban Airship joins the bunch. The new add-on makes it so developers can integrate Urban Airship’s push messaging services inside Heroku’s environment. Ideally, devs will be able to add push messaging to the web and mobile apps they produce using Heroku. “A large percent of Heroku’s customers are building mobile apps,” said Heroku CMO Matt Trifiro said in a statement. “Urban Airship in our Add-On Marketplace is an important step in offering best-in-class engagement capabilities to help ensure thriving and vibrant apps.” Portland-based Urban Airship has raised $46.6 million in funding to date from investors including August Capital, Foundry Group, Intel Capital, True Ventures, Verizon, and Salesforce. Current customers include CBS Interactive, ESPN, Groupon, Walgreens, and Warner Bros. Top photo via Urban Airship Marketing technologist? We're studying the big marketing clouds.
