startup-valuation
Startup valuation methods — pre/post-money, VC method, comparables.
When to Activate
- Valuing an early-stage or growth-stage company for a funding round
- Negotiating pre-money valuation with founders or investors
- Applying the VC method to estimate required ownership for target returns
- Selecting comparable companies and appropriate multiples for startups
- Evaluating a startup valuation for 409A, IFRS, or tax purposes
- Assessing dilution impact across multiple funding rounds
- Challenging or defending a valuation in investment committee materials
Core Concepts
Pre-Money / Post-Money Mechanics
The fundamental equation of venture financing:
Post-Money Valuation = Pre-Money Valuation + Investment Amount
Investor Ownership % = Investment Amount / Post-Money Valuation
- Pre-money valuation: The agreed value of the company immediately before the new investment. Reflects existing shareholders' implied value
- Post-money valuation: Pre-money plus the new capital raised. The investor's ownership is determined by their investment as a fraction of post-money
- Option pool shuffle: If the term sheet specifies that an option pool be created (or expanded) on a pre-money basis, existing shareholders bear the dilution. A 15% option pool on a $10M pre-money effectively values the operating company at $8.5M
- Convertible notes / SAFEs: Convert at a discount to the next priced round or at a valuation cap. The effective pre-money depends on the conversion terms — always model the fully diluted cap table
VC Method
Developed by William Sahlman at HBS. Works backward from the expected exit to determine the required ownership today.
Steps:
- Estimate terminal value: Project revenue or earnings at the expected exit date (typically 5-7 years). Apply an appropriate exit multiple
- Determine target return: VCs typically target 10-30x on early-stage, 3-5x on growth-stage, reflecting the high failure rate
- Calculate required ownership at exit: Required ownership = Investment / (Terminal Value / Target Multiple) — or more directly: Investment * Target Return / Terminal Value
- Adjust for future dilution: If the company will raise additional rounds, the investor's stake will be diluted. Retention ratio = 1 / (1 + dilution per round)^(number of rounds). Divide required exit ownership by the retention ratio to get required ownership today
- Derive pre-money: Pre-money = (Investment / Required Ownership) - Investment
Example:
Investment: $5M
Expected exit value: $200M (5 years, revenue multiple)
Target return: 10x (so need $50M at exit)
Required exit ownership: $50M / $200M = 25%
Expected dilution: Two more rounds, 20% each → retention = (1-0.20)^2 = 64%
Required ownership today: 25% / 64% = 39.1%
Post-money: $5M / 39.1% = $12.8M
Pre-money: $12.8M - $5M = $7.8M
Comparable Company Approach for Startups
Adapting public market comparables for private startups:
- Revenue multiples: EV/Revenue is the primary metric for pre-profit startups. Select comparables based on business model, growth rate, market, and stage
- Growth-adjusted multiples: EV/Revenue divided by revenue growth rate. Normalizes for growth differentials between the subject and comparables
- Discount for illiquidity: Private company valuations typically apply a 20-40% discount to public market multiples (lack of marketability)
- Discount for size/stage risk: Smaller, earlier-stage companies warrant additional discounts for execution risk, customer concentration, key-person dependence
- Sector benchmarks: SaaS (6-15x ARR for high-growth), fintech (5-12x revenue), biotech (pipeline-based, milestone-adjusted), marketplace (1-5x GMV or 5-20x take-rate revenue)
Revenue Multiples Deep Dive
For SaaS and recurring-revenue businesses:
- ARR (Annual Recurring Revenue): The standard base for SaaS valuation. More reliable than total revenue which may include services
- Rule of 40: Revenue growth rate + EBITDA margin >= 40% indicates a well-run SaaS business. Companies above this threshold command premium multiples
- Net Revenue Retention (NRR): > 120% signals strong expansion within existing customers — drives higher multiples
- CAC Payback / LTV:CAC: Efficiency metrics that influence investor willingness to pay premium multiples
- Multiple ranges (as of typical market conditions):
- NRR > 130%, growth > 50%: 15-25x ARR
- NRR 110-130%, growth 30-50%: 8-15x ARR
- NRR 100-110%, growth 15-30%: 5-8x ARR
- NRR < 100%, growth < 15%: 2-5x ARR
Berkus Method
Pre-revenue valuation framework assigning up to $500K for each of five risk-reducing factors:
Factor Value (up to)
Sound idea (basic value) $500K
Prototype (technology risk reduced) $500K
Quality management team $500K
Strategic relationships $500K
Product rollout / early sales $500K
Maximum pre-money: $2.5M
Best suited for very early stage (pre-seed, seed). Provides a structured framework for what is inherently a qualitative judgment.
Risk Factor Summation
Adjusts a base valuation by scoring twelve risk factors:
- Management risk
- Stage of business
- Legislation / political risk
- Manufacturing risk
- Sales and marketing risk
- Funding / capital risk
- Competition risk
- Technology risk
- Litigation risk
- International risk
- Reputation risk
- Potential lucrative exit
Each factor scored: -- (-$500K), - (-$250K), 0 (neutral), + (+$250K), ++ (+$500K)
Start with the average pre-money valuation for similar stage/sector companies in the region, then adjust.
Milestone-Based Valuation
Valuation increases are tied to the achievement of specific milestones:
- Technical milestones: MVP complete, beta launched, product-market fit demonstrated
- Commercial milestones: First customer, $1M ARR, 100 customers, positive unit economics
- Team milestones: Key hires (CTO, VP Sales), advisory board assembled
- Regulatory milestones: Approval, license, certification obtained
Each milestone reduces execution risk and justifies a step-up in valuation. Tranched investment structures tie funding releases to milestone achievement.
Methodology
- Stage assessment: Determine the company's stage (pre-seed, seed, Series A/B/C, growth) — this dictates which methods are most appropriate
- Financial data gathering: Collect revenue (or ARR), growth rate, burn rate, unit economics, and projections. For pre-revenue, gather product and team data
- Method selection: Apply 2-3 methods appropriate to the stage:
- Pre-revenue: Berkus, Risk Factor Summation, comparable seed rounds
- Seed/Series A: VC method, comparable transactions, revenue multiples (if revenue exists)
- Series B+: Revenue multiples, comparable companies, DCF with scenario analysis, VC method as a cross-check
- Comparable analysis: Identify 5-10 comparable companies or transactions. Adjust for growth, profitability, market, and stage differences
- Triangulation: Weigh the outputs of each method. Explain the rationale for the weighting
- Dilution modeling: Model the cap table through the current round and anticipated future rounds
- Sensitivity analysis: Show valuation under different exit assumptions, growth scenarios, and multiple environments

Projected revenue at exit: $80M
Exit multiple (EV/Revenue): 6.0x (median of comparable exits)
Terminal value: $480M
Investment & Return:
Investment amount: $8M
Target return multiple: 8x
Required proceeds: $64M
Required exit ownership: $64M / $480M = 13.3%
Dilution Adjustment:

Required ownership today: 13.3% / 70% = 19.0%
Implied Valuation:
Post-money: $8M / 19.0% = $42.1M
Pre-money: $42.1M - $8M = $34.1M
