Topo

Cut enterprise codebase onboarding from weeks to minutes

Engineering teams waste over $30k per new hire in lost velocity while developers spend weeks deciphering undocumented, sprawling codebases.

Topo transforms complex multi-repo architectures into interactive, visual execution blueprints in seconds. By instantly highlighting route handlers, ORM data relationships, and cross-service dependencies, leaders eliminate architectural drift and accelerate feature delivery. Engineering teams eliminate regression risks and conduct effortless technical audits without digging through endless directories.

Our vision is to establish the universal living blueprint for modern enterprise software systems.

Problem
  • When I onboard new engineers to our core codebase, I want them to ship production code within days, but they spend over 120 hours clicking through nested route directories and ORM models.
  • Why Now: Microservices and modular monolithic frameworks like Next.js and FastAPI have exploded in routing complexity, rendering static documentation instantly obsolete.
  • When I conduct technical due diligence for an acquisition, I want a complete visual map of data flows, but our auditors bill $50k while manually reverse-engineering legacy services.
  • When I plan a breaking database refactor, I want to trace all impacted API routes, but engineers routinely miss hidden dependencies causing catastrophic production outages.
  • Existing Alternatives: Stale Confluence diagrams, manual codebase walk-throughs, grep searches, and unmaintained Mermaid.js markdown files.
Solution
  • High-Level Concept: Interactive Google Maps for modern enterprise software codebases.
  • Instant multi-framework AST analysis that maps endpoints, middleware, services, and ORM schemas into layered interactive canvases.
  • Execution flow simulator that visually traces user requests from client actions through server routes to database writes.
  • Automated architectural drift alerts inside pull requests whenever code modifications violate defined system boundaries.
Distribution
  • High-growth Series A-C CTOs and Engineering Managers managing teams with 20+ developers.
  • Direct integration partnerships with GitHub Marketplace and GitLab App Directory for one-click repository authorization.
  • Executive outreach to boutique technical due diligence and engineering consultancy firms.
  • Targeted technical teardowns of popular open-source repositories shared directly with engineering leadership communities.
Pricing
  • Value Ladder: Free for public open-source repos
  • Pro at $29 per developer monthly
  • Enterprise at $999 monthly for unlimited private repos with SSO.
  • One Metric That Matters: Time-to-first-commit for newly onboarded engineers.
  • SAM/SOM: 45k mid-market engineering organizations spending $12k annually yielding a $540M addressable market with $1.8M Year 1 ARR target.
Scale Costs
  • SOC2 Type II compliance infrastructure with air-gapped local parser execution containers.
  • High-throughput distributed graph database infrastructure supporting 50M+ node AST relationships.
  • Continuous synchronization compute pipelines processing enterprise monorepo webhooks.
