About CloudMosa

Founded in 2009, CloudMosa operates as a technology firm specializing in high-performance web browsing solutions that utilize cloud computing to enhance speed and security. The company was established by Dr. Shioupyn Shen, a former engineer at Google and Microsoft, who now serves as the CEO. His background in computer science and experience at major tech companies spurred the development of CloudMosa's core innovations. The company has achieved significant milestones, including reaching 100 million global users for its Puffin Browser by November 2018 and surpassing 200 million downloads across Android and iOS.

CloudMosa's primary offering is the Puffin product suite, which is built upon its proprietary "Cloud Avatar" remote browser technology. This technology processes webpages on cloud servers before delivering a rendered, lightweight version to the user's device. This server-side rendering model is designed to increase browsing speed, reduce data consumption by up to 90%, and provide a layer of security by isolating the user's device from direct contact with potentially malicious web content. The product lineup includes the Puffin Web Browser, Puffin Secure Browser, Puffin TV Browser, and specialized solutions like Puffin Cloud Learning. These products cater to a diverse client base, including individual consumers, educational institutions, and enterprise customers.

The company's business model is centered on subscriptions and strategic partnerships. For consumers, CloudMosa offers both free, ad-supported versions and paid subscription tiers for its browser applications on mobile and desktop platforms, which unlock premium features like ad-blocking. For enterprise clients, the firm provides secure browser solutions that balance employee productivity with business security. CloudMosa also collaborates with telecom carriers and phone manufacturers, such as HMD (Nokia), to embed its technology on devices, particularly in emerging markets. This strategy aims to bridge the digital divide by enabling internet access on low-cost hardware. In 2015, the company raised significant capital in a Series A funding round to expand its global data center infrastructure.
