Swimm
Swimm helps engineering teams understand, document, and modernize complex codebases using a mix of static analysis, AI agents, and senior engineers. The platform maps dependencies, data flows, and business logic across repos, then turns that understanding into documentation, migration plans, and deliverables teams can verify.
Swimm offers three service tracks: API-first architecture to extract reusable backend services, an agentic development context layer that feeds validated codebase knowledge into tools like Copilot and Cursor, and large-scale migrations for .NET, Java, monolith-to-microservices, and mainframe modernization. Engagements run through a four-stage model (Assessment, Specification, Modernization, Enablement) with fixed pricing per stage.
The company is SOC 2 and ISO 27001 certified, supports on-prem and air-gapped deployments, and works with customer-managed LLMs. Swimm has analyzed over 100 million lines of code and supports legacy languages including COBOL, JCL, and PL/I alongside modern stacks.
Deterministic static analysis maps dependencies, entry points, data flows, and cross-repo relationships
Agentic context layer builds a validated knowledge base for Copilot, Cursor, Claude Code, and internal agents
Large-scale migration services for .NET, Java, monolith-to-microservices, and mainframe systems
Four-stage engagement model with fixed price per stage and validation evidence at each step
SOC 2 and ISO 27001 compliant with on-prem, cloud, and air-gapped deployment options
Combines deterministic static analysis with AI agents and human expert validation
Supports legacy mainframe languages and large enterprise codebases
Fixed-price staged engagements reduce risk on modernization projects
SOC 2 and ISO 27001 certified with flexible deployment models
Enterprise-focused with custom pricing, not self-serve for individual developers
Full modernization services require a sales engagement rather than instant signup
