Career
Nalluru is an alumnus of the Indian Institute of Technology Kanpur (IIT Kanpur). Prior to founding Moss, he worked at Microsoft, where he contributed to developer tooling related to the Azure SDK. His work at Microsoft included contributions to the Azure Developer CLI and the development of retrieval augmented generation (RAG) patterns using Azure OpenAI Service and Azure AI Search SDK. He also had experience working at AI-focused startups.[2]
Nalluru co-founded Moss alongside Sri Raghu Malireddi in 2024. The company was initially known as InferEdge before rebranding to Moss. Both co-founders previously worked at Grammarly before leaving to build the company.[3]
Moss provides a real-time semantic search runtime built in Rust and WebAssembly. The platform is designed to serve voice agents, AI copilots, and chat interfaces by enabling sub-10 millisecond retrieval times. According to the company, the system runs natively across browsers, mobile devices, and servers, requiring no additional infrastructure from users. Moss addresses a latency problem common in conversational AI products, where delays during information retrieval can disrupt the user experience. The company reports that its approach achieves 70–90% token savings compared to conventional retrieval methods.[4]
The platform is categorized within the developer tools, SaaS, and AI sectors. According to the company's website, Moss is used by over 500 teams, with clients and users at organizations including Grammarly, HubSpot, Microsoft, Zomato, Stanford University, University of California, Berkeley, and Carnegie Mellon University. As of its Y Combinator listing, Moss has three employees.[5]
