Risks

How this goes wrong

Wrong problem or bad timing

Low willingness to pay or incumbents already satisfy the job.

Watch these

  • WTP signal
    Leading
    % interviews agreeing to paid trialHealthy: ≥ 20–30%Act at: < 10%
  • Trial→Paid
    Lagging
    % trials converting to paidHealthy: ≥ 40–50%Act at: < 25%
  • Activation
    Leading
    Users hit ‘aha’ action in 1 sessionHealthy: ≥ 30–40%Act at: < 25%

What to do

  • Narrow ICP; re-interview; pivot to more painful sub-job.
  • Ship a single ‘aha’ flow; remove steps; block features behind the ‘aha’.
  • Price test early; require card for trial on premium ICPs.

Churn if onboarding is weak

Users don’t reach value in 5 minutes; poor empty states or guidance.

Watch these

  • Day-7 retention
    Lagging

  • Churn (logo)
    Lagging
    % of accounts cancelling/moHealthy: ≤ 6–8%Act at: > 10%

What to do

  • Onboarding checklists, inline coach marks, opinionated defaults.
  • Templates/sample data to ‘see success’ instantly.
  • Proactive success emails + in-app nudges to the ‘aha’ event.

Technical debt if rushed

Speedy MVP without guardrails leads to outages and slow iteration.

Watch these

  • Error rate
    Leading
    Errors per 1k sessionsHealthy: < 5/1kAct at: ≥ 10/1k

  • Deploy lead time
    Diagnostic
    Code → prodHealthy: < 1 dayAct at: > 3 days

What to do

  • Error tracking + uptime from day 1; feature flags + small PRs.
  • Simple queues/retries; circuit breakers on external APIs.
  • Weekly refactor slots; write tests for bug fixes, not all code.

Competitive moats are hard to build

Pure features are easy to copy; distribution and data matter.

Watch these

  • Unique data volume

    Events/insights only your app hasHealthy: Growing MoMAct at: Flat 2+ months
  • Partner integrations
    Diagnostic
    Live, co-marketed integrationsHealthy: ≥ 2–3Act at: < 1

What to do

  • Lean into opinionated workflows; create switching costs with data + templates.
  • Build 2–3 integrations your ICP already uses; co-market their launches.
  • Focus on speed, support, and outcomes (case studies) as enduring moat.
