Common questions.
Hashnaut is an AI Product Studio and Custom Software Development agency that designs and engineers production-ready web platforms (Next.js, React), native mobile apps (iOS, Android, React Native), and custom AI systems — including citation-backed RAG knowledge assistants, multi-agent workflows, voice agents, and enterprise LLM integrations.
Most initial web, mobile, or AI MVPs launch in 2 to 4 weeks. We operate in focused engineering sprints with weekly live demos, direct access to lead engineers, and continuous deployment so you can validate with real users rapidly.
RAG (Retrieval-Augmented Generation) securely connects a Large Language Model (LLM) to your private company documents, SQL databases, and internal wikis. Unlike generic chatbots, a RAG system grounds every response in your verified data with inline source citations and zero hallucinations.
Yes. Clients retain 100% ownership of all source code, custom models, and intellectual property. We deploy inside your private cloud VPC (AWS, Google Cloud, or Azure) using enterprise zero-data-retention APIs so your proprietary data is never used to train public AI models.
We build with modern, battle-tested technologies: Next.js, React, TypeScript, Node.js, and Python/FastAPI for web and backend platforms; Swift, Kotlin, and React Native for mobile apps; and OpenAI, Claude, Gemini, LangGraph, Model Context Protocol (MCP), PostgreSQL/pgvector, and Pinecone for AI systems.
Yes. While Hashnaut is headquartered in Reston, Northern Virginia (serving the Washington, D.C., Maryland, and Virginia tech corridor), we partner with startups, founders, and enterprise teams across the United States and worldwide.
