- Tom Blumfield, a group partner at Y Combinator, discusses the importance of metrics for startups.
Importance of Metrics (21s)
- Metrics help make informed decisions and maintain control over your startup.
- Without metrics, startups are like airplanes flying blind.
- Startups should track metrics before launching to understand user engagement and retention.
- Founders impressed investors by comprehending and effectively communicating their metrics.
Pre-launch Metrics & Metric Overload Caution [76.0 & 143.0]
- Investors can tell when founders are in command of their metrics.
- Founders should avoid metric overload before launching and not get swamped with excessive data, as proper analysis requires substantial user volume.
- Founders should also interact with their customers personally, not solely rely on metrics.
Key Metrics Selection (3m17s)
- Start with a few key metrics and choose simple solutions like Posthog for analytics.
- Ensure there’s a consensus on metric definitions within the team to avoid internal conflicts.
- Keeping consistent definitions for metrics over time is crucial, even if performance is not as hoped.
Consistency in Metrics (4m54s)
- Tracking consistent metrics is essential to gauge improvement.
- Different companies may define metrics differently, making comparisons difficult.
- Startups should establish their own consistent internal definitions for accurate progress tracking.
Investor Update Metrics (7m13s)
- B2B companies’ primary metric should be Revenue; vanity metrics like GMV can be misleading.
- Investors appreciate honest communication about metrics like Revenue, burn rate, and Runway.
Retention's Significance (9m17s)
- Retention measures the percentage of customers who continue to use and pay for a product.
- Founders should employ cohort analysis to track retention and understand customer loyalty over time.
- High retention rates enable a “layer cake” effect, building sustainable revenue over time.
- Poor retention results in a “leaky bucket” scenario, hampering business growth.
B2B SaaS: Net Dollar Retention (13m13s)
- Net Dollar Retention (NDR) is a critical metric for B2B SaaS companies, representing customer retention in revenue terms.
- A scenario is presented where a B2B startup with initial ten customers paying $10,000 monthly each expands their income from these customers to $110,000 after upsells, despite some customer churn.
- NDR above 100% indicates growth in cohort revenue over time; below 100% suggests decline.
- Target NDR for early-stage B2B SaaS companies is well over 100% due to likely underpricing, product feature additions, and improved sales skills.
- Achieving high NDR is vital; if it falls below 100%, the company should investigate and address the underlying issues rather than simply aim for new sales.
Cruciality of Gross Margin (16m50s)
- Gross margin, crucial for profitability, is revenue minus the cost of goods sold.
- For software companies, costs that vary with customer numbers, such as usage-based services (e.g., OpenAI credits), are considered cost of goods sold.
- High gross margins (around 95%) were typical for software companies in the past, but with software entering diverse industries, gross margins have become increasingly important.
- AI companies may see reduced gross margins due to costs of using foundation models from providers like OpenAI or Anthropic.
- Lower gross margin businesses must generate more sales to cover fixed costs like office rent and salaries.
- Focus on software solutions with higher gross margins is encouraged where operationally intensive businesses exist.
Challenges of Negative Margin Scaling (21m10s)
- Scaling negative margin businesses (where cost exceeds revenue per transaction) is exceedingly difficult with higher capital costs.
- Negative margins were scaled in the past with abundant capital (e.g., Uber subsidizing drivers and riders to achieve network density).
- Monzo, an online bank, scaled despite initial negative unit economics, later became profitable by reducing external vendor reliance and introducing profit-generating products and services.
- Companies should remedy negative unit economics before pursuing growth.
- Revenue is a core metric for B2B companies.
- Importance of net dollar retention exceeding 100% for the growth and health of B2B SaaS startups emphasized.
- Gross margin highlighted as critical and scaling businesses with negative gross margins is discouraged.
- Track four or five key metrics from launch to avoid "flying blind."
- Focus on meaningful metrics and not vanity metrics like gross merchandise value or unique users.
- Establish clear definitions and consistent measuring systems to prevent counterproductive debates.
- While metrics are important, directly engaging with customers is invaluable for insights and validating intuition.
