TL;DRResumen
Unit economics — the revenue and cost associated with a single customer — evolve dramatically as a company scales. Understanding what "good" looks like at each stage prevents premature scaling and helps founders make better capital allocation decisions.Cómo evolucionan los unit economics desde pre-seed hasta Serie C: qué métricas importan en cada etapa, cuándo los unit economics negativos son aceptables y el camino a la rentabilidad.
What Are Unit Economics?
The direct revenues and costs associated with a single unit of business — typically a single customer.
Key metrics: CAC, LTV, Gross Margin, Payback Period, NRR
Stage 1: Pre-Product-Market Fit (0–$500K ARR)
Unit economics are often negative or undefined — acceptable at this stage.
Focus: Finding the ICP, validating willingness to pay, understanding churn drivers.
Acceptable metrics: High and variable CAC, high churn, potentially negative gross margin
Key question: Are there any customers who love the product enough to pay and stay?
Stage 2: Early Traction ($500K–$3M ARR)
PMF is emerging. Unit economics should be improving but not yet optimized.
Target metrics: Gross margin 50%+, monthly churn < 5%, CAC payback less than 24 months, LTV:CAC greater than 1.5:1
Focus: Identifying the repeatable sales motion, reducing churn, improving gross margins
Stage 3: Growth ($3M–$20M ARR)
The sales motion is repeatable. Unit economics should be healthy and improving.
Target metrics: Gross margin 70%+, monthly churn < 2%, NRR > 100%, CAC payback less than 18 months, LTV:CAC greater than 3:1
Focus: Scaling the sales team, expanding into new segments, optimizing the funnel
Stage 4: Scale ($20M–$100M ARR)
Unit economics are strong. Focus shifts to efficiency and market share.
Target metrics: Gross margin 75%+, NRR > 110%, CAC payback less than 12 months, LTV:CAC greater than 5:1, Rule of 40 greater than 40
Focus: Operational efficiency, international expansion, product expansion
The Rule of 40
Revenue growth rate + EBITDA margin > 40%
Example: 60% growth + (-20%) EBITDA margin = 40 — acceptable
Example: 20% growth + 15% EBITDA margin = 35 — below benchmark
Key Takeaways
Key TakeawaysPuntos Clave
- Unit economics evolve dramatically across growth stages — benchmarks differ at each stage.
- Pre-PMF: focus on learning, not efficiency.
- Growth stage: target LTV:CAC greater than 3:1, NRR greater than 100%, gross margin greater than 70%.
- Scale stage: target Rule of 40 greater than 40, NRR greater than 110%, CAC payback less than 12 months.
- Premature scaling before unit economics are healthy destroys value.

¿Qué son economía unitaria??
The direct revenues and costs associated with a single unit of business — normalmente a single customer.
Key metrics:CAC, LTV, margen bruto, Payback Period, NRR
Stage 1: Pre-ajuste producto-mercado (0–$500K ARR)
economía unitaria are a menudo negative or undefined — acceptable at this stage.
Focus: Finding the ICP, validating willingness to pay, understanding churn drivers.
Acceptable metrics: High and variable CAC, high churn, potentially negative margen bruto
