Building on its earlier seed investment of $2.4 million, Neumob, a company that promises to speed up mobile apps, announced a Series A funding round of $8.5 million.

In a blog post, CEO and co-founder Jeff Kim (pictured) said the funding will be used to recruit more people, acquire business customers and bring technical enhancements to existing technologies.

The company says it reaches half a million users and recently launched Neumob Mobile App Accelerator.

“Now, app developers can increase the speed of their apps by factors of 2-10x by incorporating our SDK into their apps,” explained Kim.

“We have already done some amazing things in a short period of time by delivering SDKs for iOS and Android devices as well as building out our 49-PoP global network,” he said.

“So many businesses need us. They’re launching mobile apps all over the place, trying to squeeze in tons of functionality, but struggling to keep their apps as fast as their websites. That’s where we can help,” he added.

Kim wants to let app creators know “we’re here for them” and said the company is “putting some of its resources into building mobile’s biggest megaphone to get the word out.”

The funding round was led by Accel Partners, and they were joined by Shasta Ventures, Eniac Ventures and Lightbank Ventures.
