Section 06: MVP Roadmap & Feature Prioritization

MVP Definition & Core Value Proposition

MVP: Web app for adding and monitoring up to 5 popular APIs, detecting changelog changes via scraping/RSS, and sending email alerts for breaking changes/deprecations.

Core Problem Solved: Developers miss scattered API changelogs, leading to production outages from untracked breaking changes.

  • Must-Have Features: User authentication, API catalog addition (pre-configured 50 popular APIs like Stripe/Twilio), Basic change detection (RSS/scraping), Email alerts (severity-based), Simple dashboard with change history.
  • NOT in MVP: GitHub/code impact analysis, response diffing, Slack/PagerDuty integrations, team collab, advanced AI classification, unlimited APIs.

User Success

  • User adds 3 APIs and receives first alert within 24hrs
  • Dashboard shows clear change summaries; 80% acknowledgment rate

Business Success

  • 100 users acquired Month 1
  • 40% D30 retention
  • 15% free-to-paid conversion

Validation Goals: Test if users add >3 APIs/week and find alerts actionable (NPS >30).

Phased Development Roadmap

Phase 1: Core MVP (Weeks 1-8)

Objective: Launch a functional product validating core value—users monitor 5 APIs and get reliable email alerts for changes. Prioritizes low-code setup for speed, focusing on 50 pre-config APIs to minimize config friction. Unlocks immediate user value: time saved scanning changelogs manually (est. 2hrs/week/user). Targets solo founder build with 30% effort buffer.

  • Functional E2E flow
  • 50 beta users
  • >60% workflow completion

Deliverable: Beta-ready MVP.

Phase 2: Product-Market Fit (Weeks 9-16)

Objective: Add quick wins to boost retention (e.g., filters, digests) and introduce monetization via Stripe. Integrate basic GitHub for impact preview. Validate PMF with retention data; iterate on alert accuracy (>90% true positives). Enables free-to-paid upsell with 50-API limit.

Deliverable: Monetized PMF product.

Phase 3: Growth & Scale (Weeks 17-24)

Objective: Scale with Slack/PagerDuty, response diffing. Optimize acquisition via referrals. Hit $3K MRR.

Success: 1K users, >0.3 viral coeff, $3K MRR.

Phase 4: Expansion (Months 7-12)

Objective: Enterprise: SSO, API diffs, custom integrations. $15K MRR, Series A ready.
