Optimizing AI interference MoreLess
Wafer is a startup developing an AI-native operating system by forking Android. The company, led by CEO Sam Hall, aims to create a hardware-agnostic OS that supports various AI agent form factors, positioning apps as data providers or back-ends. This strategy places Wafer at the OS-level of AI assistant development, a layer being explored by other major AI companies, to gain deeper access to user data across different applications.
The company's approach is to weigh the trade-offs between the distribution challenges of building lower in the tech stack against the significant advantages of data access. By focusing on an OS-level integration, Wafer is targeting the opportunity within Android's open ecosystem for custom, AI-first computing experiences. This could potentially provide non-Google Android original equipment manufacturers (OEMs) with the technology to build AI-native smartphones. The company is backed by Susa Ventures.
