Moderne

Moderne builds tooling for large-scale code analysis and automated refactoring across enterprise software portfolios. Its technology parses repositories into a Lossless Semantic Tree (LST) — a type-attributed, format-preserving, incrementally compiled model of source code derived from the OpenRewrite open-source project — and applies deterministic transformations called recipes against that model. Recipes rewrite matched patterns and re-emit source while preserving comments and formatting, and can be composed into larger transformations that run identically across one repository or, per the company, 100,000.

The product set includes the Moderne Platform, a private-SaaS application where users run recipes, create pull requests and generate reports across repositories without writing code; the Moderne CLI, a local Git-like command line tool for building LST artifacts and running or testing recipes across many repositories; Moderne DX, an air-gapped or on-premises refactoring CLI/IDE deployment for highly secure environments; an IntelliJ IDEA plugin for cross-repository code search and recipe development; Moddy, a multi-repository AI agent that pairs LLMs with LST data to find and execute recipes from natural-language requests; and agent tooling including Prethink recipes and a Moderne MCP server that expose the code model and recipe library to coding agents. Typical use cases are framework and language-version migrations, cloud and database platform moves, remediation of security vulnerabilities and CVEs, organization-wide type-aware code search, and code-quality standardization.

Architecturally, customers publish serialized LST artifacts to an artifact repository through mass ingestion; an on-premises Moderne Connector bridges the customer network to the Moderne API gateway over RSocket, sending encrypted LST and custom-recipe artifacts, with the encryption key retained in the customer environment. The gateway uses Apollo Router to federate GraphQL schemas across Moderne microservices, and can proxy requests to LLM providers for AI features. Moderne states it is SOC 2 Type 2 compliant and can provision a private SaaS in a customer's chosen cloud provider or region.

Founding story

Moderne was co-founded by Jonathan Schneider (CEO) and Olga Kundzich (CTO), former colleagues at Pivotal Software, which VMware acquired in 2019. The product is based on OpenRewrite, the large-scale automated refactoring tool Schneider developed during a stint at Netflix, which the company describes as a de facto standard for code migration and maintenance.

Business model

Moderne sells an enterprise software platform, delivered as a private SaaS tenant in a customer-selected cloud provider or region, with complementary local CLI, IDE plugin and an air-gapped/on-premises deployment option (Moderne DX). It maintains a catalog of prebuilt recipes while allowing customers to author and run their own, and has built a go-to-market organization including sales leadership and reps.

Traction

Moderne reported growing its customer base by 250% in 2024, with customers including Allstate, Choice Hotels, Walmart, top North American banks and Scentbird. It cites a catalog of over 7,000 recipes in the Platform (described elsewhere as tens of thousands across 40+ domains and 10+ languages) and a reference outcome of one Log4Shell recipe fixing 38,000 call sites across 400 repositories with zero regressions. Total disclosed funding is $50 million and headcount is approximately 40.

Latest developments

Moderne has repositioned its platform around agent-facing tooling, describing the Lossless Semantic Tree as a "code genome" and offering Prethink recipes and a Moderne MCP server that supply coding agents with resolved codebase context and the recipe library, plus Moddy, a multi-repo AI agent. Recipes are being moved from Maven Central to the Code Genome Project, requiring customers to configure access for releases to resolve. The company was named a Leader in the first Gartner Magic Quadrant for AI-Augmented Code Modernization Tools, is hosting an AI Software Factory Summit on February 22-24, 2027, and is hiring across engineering, product and go-to-market. Stated priorities after the Series B include extending into application security and investing in large-scale agentic AI experiences.
