Identify Startup Growth Metric Red Flags

Business Context

PulsePay is a B2B fintech startup offering expense management software to small businesses. The CEO says the company is "growing fast," but investors are concerned that top-line growth may be masking weak fundamentals.

Metric Scenario

Over the last 6 months, monthly signups increased from 20,000 to 52,000, and MRR grew from $420,000 to $610,000. However, paid conversion fell from 8.5% to 5.2%, 90-day logo retention dropped from 78% to 61%, and CAC rose from $180 to $340. DAU/MAU improved from 22% to 28%, but average weekly active users per paying account declined from 6.4 to 4.9. Referral-driven signups fell from 24% to 11%, while paid acquisition now drives 68% of new users versus 41% six months ago. Sales argues this is normal scaling friction; the board wants to know which metrics are true red flags.

Requirements

1. Define the most important growth metrics you would review first for an early-stage startup like PulsePay.
2. Identify the clearest red flags in the data above and explain why they matter.
3. Decompose growth into acquisition, activation, conversion, retention, and monetization to determine whether growth is healthy or fragile.
4. Prioritize which issues should be escalated immediately to the CEO and board.
5. Recommend 3-5 follow-up analyses or dashboards to validate whether the company has a sustainable growth engine.
