Every company, from digital startups to bricks-and-mortar companies, need to develop mobile apps and APIs to compete in the digital economy. Despite the increasing demand from consumers for more and more powerful mobile apps, the resources required to deliver them are largely beyond the scope of most companies.

One month after announcing $20 million in new financing, API company Apigee is looking to solve this problem by launching a self-service version of its enterprise API platform. These are the same tools used by AT&T, eBay, Gilt Groupe, Netflix, and Walgreens for delivering, managing, and analyzing their APIs and apps. Users will be able to access Apigee’s complete set of services at no cost, up to 3.5 million API calls per month — beyond that, the enterprise version starts at $9,000 per month based on traffic and storage capacity.

“Apps are quickly changing the way we all interact and do business – and APIs bring apps to life with rich streams of data and Web services,” says Apigee CEO Chet Kapoor. “We’ve now taken this technology and simplified it so that any organization – from a developer in a garage to a Fortune 50 company – can launch like a startup and scale like an enterprise.”

The now free enterprise-grade features include: “Gateway Services, for safely exposing, managing, and scaling APIs; App Services, for building apps with APIs; Developer Channel Services, for creating a developer community around APIs and apps; and Analytics Services, for generating critical business insights from API data,” according to the company.

Apigee has been growing rapidly with nearly 20 percent of the Fortune 100 using its services and over 100 billion API calls per month running through its platform. The company’s recent funding in July brought its total financing to $72 million. Investors include Focus Ventures, Bay Partners, Norwest Venture Partners, SAP Ventures, and Third Point Ventures.

Adding some context to the argument that all companies need apps, Apigee released a survey of 2,200 individuals this week highlighting the importance of mobile apps for to the upcoming holiday shopping season. The findings show that 57 percent of mobile app users would consider purchasing their holiday gifts this year on a mobile device. Also, 82 percent of mobile app users see benefits of shopping via mobile app and 54 percent suggest there could be consequences for retailers that don’t have a mobile app.

“These findings demonstrate that the app economy is having a big impact on the way we live, and people are increasingly demanding a lot more from the apps they use every day,” says Kapoor. “APIs are the ‘magic ingredient’ in mobile apps, and Apigee’s new API platform is helping build a digital world where we all shop, communicate, and connect across apps on trillions of mobile devices.”
