Key Metrics for E-Commerce Startups at Series A

These are the 6 metrics that institutional investors evaluate for E-Commerce startups. DDR automatically extracts and benchmarks these from pitch deck data and OSINT sources.

Customer Acquisition Cost (CAC)
Meta/Google: $30–$100 consumer | <$300 for premium
Must be recoverable within 2–3 purchase cycles
Customer Lifetime Value (LTV)
LTV:CAC ratio >3x required | >5x is healthy
Subscription models dramatically increase LTV
Repeat Purchase Rate
>40% within 12 months for consumables | >25% for durables
One-time purchase brands cannot scale profitably on paid ads
Gross Margin
30–60% depending on product; supplements/beauty = higher
Gross margin determines how much can be spent on marketing
Return Rate
<15% for apparel | <5% for consumables
High return rates compress margins significantly
Blended ROAS (Return on Ad Spend)
>3x for profitable growth | >5x for efficiency
Must account for full customer journey, not last-click

Red Flags in E-Commerce Pitch Decks

DDR detects these 4 sector-specific red flags automatically when screening an E-Commerce startup pitch deck. Each flag is severity-weighted based on impact to investment thesis.

CRITICAL
Business entirely dependent on Meta/Google paid advertising with no organic
If >90% of revenue comes from paid ads with no organic, word-of-mouth, or retention, the business is a margin-compression machine as CAC rises.
CRITICAL
Gross margin below 30%
Below 30% gross margin, there is insufficient room to fund customer acquisition, marketing, and operations. Most D2C brands need 50%+ to be viable at scale.
HIGH
LTV:CAC ratio below 2x
Below 2x LTV:CAC, the business cannot sustainably acquire customers. Either CAC must decrease or LTV must increase through repeat purchases or AOV growth.
MEDIUM
All manufacturing concentrated in a single country/supplier
Single-source manufacturing creates existential supply chain risk. COVID demonstrated how a single disruption can destroy an e-commerce brand.

Key Questions to Ask the Founder

  2. Walk me through your unit economics: CAC by channel, LTV by cohort, gross margin by SKU
  3. What happens if Meta's CPMs increase 30% next quarter?
  4. How many suppliers could make your core product and how quickly could you switch?
