Outcome: Working MVP with user authentication and core features.
Week 3: Launch Preparation
Marketing Setup:
## Launch Checklist
1. Landing page (Vercel-hosted Next.js)
2. Email collection (Tally forms → Mailchimp)
3. Social media content (Buffer scheduling)
4. Analytics tracking (PostHog events)
5. Documentation (Notion workspace)Content Creation:
- Write launch blog post (Notion → export → deploy)
- Create social media graphics (Canva)
- Schedule launch day posts (Buffer)
- Setup email welcome sequence (Mailchiip free tier)
Tools Activated:
- Tally (waitlist forms)
- Mailchimp (email marketing)
- Buffer (social scheduling)
- Canva (design assets)
- Notion (documentation)
Outcome: Complete launch funnel ready to drive signups.
Week 4: Launch & Iterate
Launch Day Workflow:
# 1. Deploy production version
git checkout main
git merge develop
vercel --prod
# 2. Activate monitoring
# - PostHog session recordings ON
# - Sentry error tracking ON
# - Supabase logs monitoring
# 3. Social media blitz
# - Buffer publishes scheduled posts
# - Monitor engagement in real-time
# - Respond to feedback via Gmail
# 4. Data collection
# - Tally forms capture signups
# - Mailchimp sends welcome emails
# - PostHog tracks user behaviorDaily Iteration Cycle:
- Check PostHog analytics (user behavior)
- Review Sentry errors (fix bugs)
- Read user feedback (Gmail + social)
- Document learnings (Notion)
- Plan next features (GitHub Projects)
- Ship improvements (Vercel auto-deploy)
Outcome: Live product with active users and data-driven improvement loop.
Integration Flow Examples
Flow 1: Code to Production
Complete deployment pipeline from code to live site with monitoring.

# 2. Commit and push
git add .
git commit -m "feat: add user dashboard"
git push origin main
# 3. Vercel auto-deploys (triggered by push)
# 4. Supabase migrations run automatically
# 5. PostHog tracking activates on new pages
# 6. Sentry monitors for errors
# Result: New feature live in ~2 minutesFlow 2: User Signup to Engagement
Complete user acquisition and onboarding flow.

## Content Pipeline
1. **Draft**: Write blog post in Notion
2. **Review**: Share Notion page for feedback
3. **Export**: Download as Markdown
4. **Deploy**:
- Add to `content/blog/`
- Git push triggers Vercel build
5. **Distribute**:
- Buffer schedules social posts
- Mailchimp sends to subscribers
6. **Measure**:
- PostHog tracks page views
- Analytics measure engagement
- Notion documents learningsKey Integration Points
GitHub ↔ Vercel ↔ Analytics
Setup:
# Connect GitHub repo to Vercel
vercel link
# Add PostHog environment variables
vercel env add NEXT_PUBLIC_POSTHOG_KEY
vercel env add NEXT_PUBLIC_POSTHOG_HOST
# Every push triggers:
# 1. Vercel build
# 2. PostHog tracking activation
# 3. Analytics data collectionTally ↔ Mailchimp ↔ Gmail
Email Workflow:
// Tally webhook sends to Mailchimp
// Mailchimp automation:
// - Day 0: Welcome email
// - Day 2: Feature introduction
// - Day 7: Ask for feedback
// Gmail receives:
// - User replies (manual response)
// - Mailchimp notifications
// - Feedback submissionsBuffer ↔ Analytics ↔ Notion
Content Analytics Loop:
1. Schedule posts in Buffer
2. Posts include UTM parameters:
- `?utm_source=twitter&utm_campaign=launch`
3. PostHog tracks traffic from social
4. Review analytics in PostHog
5. Document insights in Notion:
- Which platforms drive signups?
- What content resonates?
- Optimal posting times?
6. Refine Buffer strategy based on dataPro Tip: Setup weekly review ritual using this stack:
- Monday: Check PostHog analytics (what happened?)
- Wednesday: Review Sentry errors (what broke?)
- Friday: Document learnings in Notion (what did we learn?)
- Sunday: Plan next week in GitHub Projects (what's next?)
Real-World Example
SaaS Product: "DevTimer" (Time Tracking for Developers)
Month 1 Results:
- 127 signups (Tally → Mailchimp → Supabase)
- 89 active users (PostHog tracking)
- 12 bugs fixed (Sentry → GitHub → Vercel)
- 23 features shipped (GitHub → Vercel)
- $0 infrastructure costs
Tools in Action:
- Cursor AI: Wrote 70% of initial codebase
- Supabase: Handled all user data and auth
- Vercel: 847 deployments (every push)
- PostHog: Tracked 12,000+ events
- Sentry: Caught 12 critical errors
- Buffer: Scheduled 60 social posts
- Mailchimp: Sent 400+ emails
- Notion: 150+ pages of documentation
Reality Check: The free tier limits will appear around Month 2-3:
- PostHog: 1M events/month (upgrade to $0-20/month)
- Mailchimp: 1,000 contacts (upgrade to $13/month)
- Supabase: 500MB database (upgrade to $25/month)
Total cost at scale: ~$58/month for 1,000+ users
