Neumob was a technology company that developed application acceleration software for mobile apps, targeting app owners and developers worldwide. Its core product, the Neumob Accelerator SDK, embedded into mobile applications to boost load times by 30-300%, cut errors and timeouts by up to 90%, and reduce bandwidth usage, serving clients like HotelTonight, The Economist, and The Wall Street Journal.[1][2][5] The company addressed critical mobile performance issues on 2G, 3G, and 4G networks using machine learning-driven protocols and real-time traffic optimization, but it ceased independent operations after Cloudflare acquired it in 2017 and the entity was marked as closed.[1][2]
Founded in 2014 and headquartered in Sunnyvale, California, Neumob emerged to tackle mobile app slowdowns in a mobile-first era.[1] Key founders included Jeff Kim (Co-Founder & CEO) and Junho Choi (Co-Founder & CTO), who built early traction with their SDK that delivered measurable gains in app speed and reliability.[1][2] Pivotal momentum came from partnerships with major apps, proving the tech's value in retaining users and driving revenue, which positioned Neumob for acquisition by Cloudflare in November 2017.[2]
Neumob rode the mobile app explosion trend in the mid-2010s, when slow networks and high error rates eroded user retention amid rising smartphone adoption.[2][5] Its timing aligned with surging demand for edge computing and last-mile optimization, as apps competed for engagement on unreliable connections—market forces like data caps and 4G limitations amplified its relevance.[1][2] By integrating with Cloudflare's network, Neumob influenced the ecosystem by extending CDN benefits to mobile, paving the way for unified performance-security stacks and inspiring hybrid acceleration tools still used today.[2][6]
Neumob's legacy endures within Cloudflare, where its SDK enhances products like Argo and Warp, optimizing mobile data flows end-to-end for a "better Internet."[2][6] Looking ahead, as 5G/6G and edge AI evolve, Neumob's mobile-first acceleration principles will shape trends in low-latency apps, IoT, and global connectivity—potentially expanding via Cloudflare's ongoing innovations. This acquisition exemplified how specialized tech fuels broader platform dominance, turning a niche accelerator into enduring infrastructure.
Neumob has raised $11.0M across 2 funding rounds. Most recently, it raised $9.0M Series A in September 2015.
