Moderne, Inc.

Moderne, Inc. is a privately held software development company specializing in automated code refactoring, remediation, and modernization at scale. Founded in 2020 by Jonathan Schneider and Olga Kundzich, the company's mission is to enable mass-scale modernization of code infrastructure, enhance visibility into source code, and automatically fix, upgrade, and secure codebases. Headquartered in San Francisco, California, Moderne aims to free developers to focus on creating new software by automating the maintenance of existing code.

Moderne's core offerings include the Moderne Platform, a hosted SaaS solution built on its proprietary Lossless Semantic Tree (LST) data model, which provides a comprehensive suite of tools for estate-wide code change. This platform integrates a recipe catalog, command-line interface (CLI), integrated development environment (IDE) plugins, and agent tools for AI coding agents. The company's technology is underpinned by OpenRewrite, an open-source automated refactoring tool. Key products such as Prethink provide AI agents with structured knowledge for improved reasoning, while Changelog offers unified visibility across multi-repository software engineering. Moderne also features Trigrep for LST-backed indexed code search and the Moddy multi-repo AI agent. These solutions cater to enterprises with extensive and complex codebases, including Fortune 100 companies like Morgan Stanley, American Express, Allstate, Choice Hotels, and Walmart.

In recent developments, Moderne was named a Visionary in the inaugural Gartner® Magic Quadrant™ for Technical Debt Management Tools in May 2026. The company also launched Prethink in February 2026 to enhance AI code governance and introduced Changelog in May 2026 to bridge source and change control for AI-driven, multi-repository software engineering. In February 2025, Moderne secured $30 million in Series B funding, led by Acrew Capital, bringing its total funding to $50 million. The company's technology, OpenRewrite, has been integrated into major developer tools such as AWS's Amazon Q, Broadcom's App Advisor, and Microsoft's GitHub Copilot, solidifying its position in the market for automating code refactoring and technical debt management.
