What You'll Learn The four mistakes that kill growth-stage companies—and how to avoid them.

Learn From Others' Failures

The same mistakes kill companies year after year. Learn from others so you don't repeat them.

Each pattern includes the symptoms, the root cause, and the fix.

Pattern #1: The Growth Hacking Addiction

The Symptom

The team chases "silver bullets" every week. Always a new trick that's going to change everything.

  • Growth is spiky and unpredictable
  • The team celebrates viral moments but can't replicate them
  • "What's our growth hack this week?"
  • High energy, low sustainable results

The Solution

Shift focus from tactics to systems. Build repeatable growth loops, not one-time hacks.

  • Map your growth loops (Chapter 1)
  • Focus on the constraint (Theory of Constraints)
  • Measure loop velocity and strength
  • Accept that sustainable growth is boring
Root Cause

Early on, scrappy hacks worked. At scale, they create chaos. You need systems now, not stunts.

Pattern #2: The Vanity Metric Trap

The Symptom

Dashboards look great while the real numbers stay flat.

  • "We hit 100,000 sign-ups!"
  • Revenue is flat despite growing traffic
  • Activation and retention are ignored
  • Team optimizes for applause, not value

The Solution

Implement the Cascade Effect analysis. Force every metric to be tied to downstream value.

  • Use the Funnel Cascade Optimizer (Chapter 2)
  • Report "Downstream Impact" for every initiative
  • Optimize for LTV, not sign-ups
  • Ask: "Does this create customers who pay and stay?"
The Test

For any metric you're celebrating, ask: "If I doubled this and nothing else changed, would the business be better off?" If doubling sign-ups doesn't improve revenue or retention, sign-ups are a vanity metric.

Pattern #3: Infrastructure Debt Collapse

The Symptom

The tech foundation crumbles as you grow.

  • Site goes down during marketing campaigns
  • Deployment frequency drops from daily to weekly
  • Engineers spend more time firefighting than building
  • "Don't touch that code—it'll break everything"

The Solution

Fix tech debt before you scale, not during.

  • Use the Infrastructure Scaling Planner (Chapter 5)
  • Respect microservices trigger points
  • Build 100%+ infrastructure headroom
  • Schedule "tech debt sprints" before growth pushes

The Tech Debt Calendar

Before any major push (fundraise, launch, big campaign), schedule a tech debt sprint:

Timing Focus Duration
Before fundraise Stability, monitoring, documentation 2-4 weeks
Before major launch Load testing, auto-scaling, caching 1-2 weeks
Quarterly maintenance Dependency updates, security patches 1 week

Pattern #4: Cultural Dilution

The Symptom

The company doesn't feel like the same place anymore.

  • "It doesn't feel like the same company"
  • Politics and bureaucracy increase
  • Early employees leave
  • New hires don't understand the mission
  • Decisions slow down as hierarchy grows

The Solution

Use structure to keep culture intact as you grow.

  • Implement Squads and Tribes (Chapter 5)
  • Respect Dunbar's Number (~150 people)
  • Document culture explicitly, not implicitly
  • Create rituals that reinforce values
  • Give teams autonomy within clear boundaries
The Culture Preservation Playbook
  1. Codify Values: Write down what you believe, not what sounds good. Make them specific and actionable.
  2. Hire for Values: Use structured interview questions that assess cultural alignment.
  3. Create Rituals: Weekly all-hands, monthly retrospectives, quarterly off-sites. Rituals maintain connection.
  4. Maintain Small Teams: Keep squads under 8 people. The "two-pizza rule" exists for a reason.
  5. Celebrate the Right Behaviors: What you publicly praise is what people will do.

The Prevention Checklist

Use this weekly hygiene checklist to catch failure patterns early:

Growth Hygiene Practices

Weekly
  • Review North Star metric (1-2 metrics that truly matter)
  • Check leading indicators for each growth loop
  • Monitor infrastructure health score
Monthly
  • Audit each growth loop: strength, velocity, friction
  • Review funnel cascade analysis
  • Check burn multiple trend
Quarterly
  • Identify and address the single biggest constraint
  • Conduct culture check (employee survey, exit interviews)
  • Review LTV:CAC and NRR trends
Bi-Annually
  • Conduct architecture review and tech debt assessment
  • Evaluate org structure (is it still serving you?)
  • Run hypergrowth readiness assessment

The Common Root Cause

The Underlying Pattern

All four failures come from the same root cause: chasing short-term wins instead of building systems.

  • Growth hacking addiction: quick wins over sustainable loops
  • Vanity metrics: impressive numbers over real value
  • Infrastructure collapse: fast shipping over solid foundation
  • Cultural dilution: fast hiring over careful integration

The fix is always the same: build systems, track what matters, and skip the shortcuts.

Key Takeaways

Remember These Truths
  1. Growth hacking is a phase, not a strategy. Replace tactics with systems.
  2. If a metric doesn't connect to revenue, it's vanity. Follow the cascade to LTV.
  3. Tech debt has compound interest. Pay it before you scale, not after.
  4. Culture doesn't scale automatically. Use structure to preserve what matters.
  5. Prevention is cheaper than cure. Weekly hygiene beats quarterly crisis management.
