# Deprecationfuel

*/Startups/Deprecationfuel*

## Startup Overview

This development tool maps and replaces deprecated library dependencies across entire code repositories. Instead of merely flagging outdated versions, it executes the structural code changes required to migrate away from obsolete packages. The system analyzes dependency trees, identifies breaking changes, and rewrites the affected codebase to utilize the target library's new syntax.

Engineering teams typically rely on manual updates or basic alerting systems like Dependabot and SonarQube, which notify developers of deprecations but leave the actual code rewrite to human engineers. This manual process stalls feature development when teams face sweeping, multi-file refactoring tasks. By automating complex cross-repository rewrites, this platform eliminates the engineering hours spent on routine dependency maintenance. The service charges only for each successful migration rather than per seat or repository, aligning costs directly with removed technical debt.

## Startup Founding Hypothesis

## Startup Offer

**Proof**:
- Target: Engineering organizations clearing multi-year technical debt backlogs in under 45 days.
- Target: DevOps teams upgrading major framework versions with zero manual syntax rewriting.
- Target: Principal engineers reclaiming 10+ hours a month previously spent fixing broken APIs.
**Tiers**:
- Name: Direct Migration · Price: ~$10–$25 per successful migration · Inclusions: Automated replacement of deprecated methods for public registry libraries, spanning up to 10 files per pull request.
- Name: Complex Refactoring · Price: ~$50–$90 per successful migration · Inclusions: Multi-file AST transformations, including interface adjustments, parameter rewriting, and associated unit test updates.
- Name: Enterprise Volume · Price: ~$2,000–$4,000/month · Inclusions: Unlimited automated migrations across up to 100 repositories, including mapping capabilities for proprietary internal libraries.
**Guarantee**: You are only billed for migrations that compile; if the generated pull request fails your existing continuous integration (CI) test suite, you are not charged.
**Business Function**: ProvideService
**Objection Handlers**:
- Objection: Dependabot already handles our dependency updates. Rebuttal: Dependabot only bumps version numbers; Deprecationfuel rewrites the actual codebase to fix the broken methods and interfaces that result from the bump.
- Objection: Automated refactoring might introduce subtle business logic bugs. Rebuttal: Deprecationfuel maps Abstract Syntax Trees (AST) strictly based on library documentation and will only submit PRs designed to pass your existing test coverage.
- Objection: We cannot grant read/write access to a third-party SaaS. Rebuttal: The platform is designed to deploy as an isolated, self-hosted runner or scoped CI workflow with tightly bound branch permissions.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- 14-day scoped CI workflow pilot: Deploy on a single repository with known technical debt, targeting 15 successfully compiled pull requests that replace deprecated methods without manual developer intervention.
- 30-day self-hosted runner pilot: Map a custom internal library across 5 dependent microservices, aiming to completely upgrade the internal API usage while maintaining a 100% passing test suite.
**Target Metrics**:
- Target: 95% continuous integration test pass rate for automatically generated refactoring pull requests
- Aim: 40 developer hours saved per major framework upgrade by eliminating manual parameter rewriting
- Target: 100% of deprecated methods replaced within a single 30-day technical debt sprint
- Target: 0 manual syntax corrections required for direct migrations of standard public registry libraries
**Target Case Studies**:
- Mid-market financial software engineering department: Mapping proprietary internal libraries to transition a legacy codebase to a new framework version, generating compiling pull requests for hundreds of interface adjustments.
- Enterprise SaaS DevOps team: Clearing a multi-year technical debt backlog by automatically rewriting deprecated API calls across dozens of microservices following a major automated dependency bump.
- Growth-stage startup platform engineering group: Executing multi-file AST transformations to replace an unmaintained public registry library across their monorepo without breaking existing continuous integration tests.
**Testimonial Targets**:
- Staff Engineer: Valuing the strict AST-based mapping that ensures refactoring pull requests pass existing test coverage without altering underlying business logic.
- VP of Engineering: Expressing confidence in the pay-per-compiling-migration model, noting that the engineering budget only pays for code that actually builds.
- DevOps Lead: Highlighting the security of the isolated CI runner deployment, emphasizing that the tool strictly respects tightly bound read/write branch permissions.

## Startup Top Risks

**Risks**:
- Severity: existential · Description: Automated multi-file refactoring introduces silent runtime errors into customer codebases, causing catastrophic outages and immediate loss of trust. · Mitigation Status: in-progress
- Severity: high · Description: The pricing model based on successful migrations leads to revenue disputes when customers reject pull requests due to stylistic preferences or edge-case test failures. · Mitigation Status: unmitigated
- Severity: high · Description: GitHub integrates advanced multi-file AST refactoring directly into Dependabot for free, instantly commoditizing the core value proposition. · Mitigation Status: unmitigated
- Severity: moderate · Description: The mapping engine fails to parse highly customized or undocumented internal library usages, restricting the addressable market to simple public open-source dependencies. · Mitigation Status: in-progress
