Virstack LLC

Virstack is a software company that builds AI products and delivers custom AI agent implementations for businesses. We call our approach Engineering Guided AI. Experienced engineers own the architecture and review the code, so responsibility for what we ship never gets handed off to AI. Our AI tooling is guided by our own skill files, built from decades of hands-on engineering experience, which lets us move fast without cutting corners. We build across web, desktop, mobile and cloud. Our work includes voice AI agents that handle real customer conversations, AI governance and cost control tooling, retrieval augmented chatbots, document processing pipelines, and full-stack platforms on Node.js, TypeScript, MongoDB, AWS and Flutter. Alongside client work, we build and launch our own products, from AI cost governance platforms to mobile apps on the App Store. We also offer cybersecurity services through our partnership with TPx, so clients get a single partner for building and securing their systems. Whether a client needs an AI agent in production, an existing app taken over and modernized, or a new product built from scratch, Virstack brings the speed of AI with the accountability of real engineering.
