Vespper (YC F24) builds infrastructure that lets AI agents produce real Microsoft Word documents. Its product is a docx MCP (Model Context Protocol) server that turns raw agent output into clean, tracked, review-ready .docx files - aimed at regulated, legal, and compliance workflows where the final artifact has to be a Word doc with tracked changes, not a chat window. The two-person, Tel Aviv-based team originally launched an open-source, 24/7 AI on-call engineer for incident triage before pivoting into agent document infrastructure.

x1 is the world's most powerful AI app studio, built for iOS.

With modular studios for product design, branding, onboarding, monetization, and growth, x1 is what happens when someone finally takes AI-assisted app development seriously.

Zeroframe is the company behind Andoria, an AI-powered customer onboarding agent that learns how web applications work and generates personalized walkthroughs for users who get stuck.
