How to Value a Startup: 6 Valuation Methods for Every Stage

Startup valuation is not guesswork — it is structured evidence. The right method depends on your stage, your metrics, and the intangible assets you have built. This guide covers six proven methods from pre-seed through Series B, with worked examples and the intangible asset overlays that produce stronger valuations.

Why Startup Valuation Is Really About Intangible Assets

When an investor values your startup, they are pricing your future. But that future is built on what you have already created: proprietary technology, customer relationships, a team that can execute, a brand that resonates, data that compounds. These are intangible assets, and they represent over 90% of enterprise value in technology companies.

Most valuation methods capture intangible assets implicitly — through revenue multiples, growth rates, or comparable transactions. But founders who explicitly measure and present their intangible asset portfolio achieve stronger outcomes at every funding stage.

Key Takeaway: Every valuation method below can be strengthened with an intangible asset overlay. The overlay does not replace the method — it provides the evidence that supports a higher number.

Method 1: The Berkus Method (Pre-Revenue)

Created by angel investor Dave Berkus, this method assigns value to five key risk factors, each worth up to £500K, for a maximum pre-money valuation of approximately £2.5M.

Risk FactorWhat It MeasuresMaximum Value
Sound IdeaMarket opportunity, problem-solution fit£500K
PrototypeTechnology risk reduction£500K
Quality TeamExecution capability, domain expertise£500K
Strategic RelationshipsCustomer pipeline, partnerships£500K
Product Rollout / SalesMarket traction, early revenue signals£500K
Opagio Enhancement: Each Berkus factor maps directly to an intangible asset category. Opagio's framework adds structured measurement to each factor — transforming subjective assessment into evidence-based scoring.

Best for: Pre-seed and seed-stage startups with no revenue. Particularly useful for first conversations with angel investors.

Method 2: The Scorecard Method (Pre-Revenue to Seed)

The Scorecard Method compares your startup against a regional median pre-money valuation for similar-stage companies, adjusting for weighted factors.

FactorTypical Weight
Strength of the team30%
Size of the opportunity25%
Product / technology15%
Competitive environment10%
Marketing / sales channels10%
Need for additional investment5%
Other5%

Your comparison factor for each category (expressed as a percentage above or below the median) is multiplied by the weight, summed, and applied to the median valuation.

Opagio Enhancement: Opagio adds an 8th factor — Intangible Asset Score — that captures assets the standard scorecard misses: data assets, organisational capital, and founder network value.

Best for: Seed-stage startups in markets with visible comparable deal data. Strong in geographies with active angel networks.

Method 3: Revenue Multiple (Series A+)

The most widely used method for revenue-generating startups. The formula is straightforward:

Formula Valuation = ARR × Revenue Multiple

The multiple varies significantly based on growth rate, capital efficiency, and market. SaaS benchmarks for 2025–2026 typically range from 5–8x ARR for moderate growth (20–40% YoY) to 15–25x for high growth (100%+ YoY) with strong unit economics.

Growth ProfileTypical ARR MultipleKey Drivers
Moderate (20–40% YoY)5–8xCapital efficiency, profitability path
Strong (40–80% YoY)8–15xNDR > 120%, low churn
Exceptional (80%+ YoY)15–25xCategory creation, network effects
Opagio Enhancement: Revenue multiples are adjusted upward when intangible asset strength is demonstrated. A startup with 140% NDR and proprietary data assets commands a higher multiple than one with identical revenue but weaker intangible foundations.

Best for: Series A and beyond, where trailing revenue data exists. The default method in most term sheets.

Method 4: VC Method / Reverse DCF

The VC Method works backwards from a target exit. It asks: if we want a specific return, what should we pay today?

Formula Pre-Money = Terminal Value ÷ Target Return Multiple

A VC targeting 10x on a company they believe will exit at £100M values the pre-money at £10M today. The sophistication is in justifying the terminal value assumption — and this is where intangible asset evidence becomes critical.

Example: A SaaS startup projects £15M ARR in 5 years. At a 10x exit multiple, terminal value is £150M. A VC targeting 15x returns values the pre-money at £10M. But if the founder can demonstrate that their technology IP, data moat, and customer relationships will support a 15x exit multiple (not 10x), the terminal value rises to £225M and pre-money to £15M — a 50% improvement.

Best for: Any stage where you are negotiating with institutional VCs. Essential for Series A and B conversations.

Method 5: Replacement Cost

Values the startup by estimating what it would cost to rebuild everything from scratch. This is particularly powerful for technology-heavy startups where development investment is substantial.

Replacement cost includes direct development costs (engineering hours, design, testing), plus overhead, developer profit margin, and adjustments for functional and economic obsolescence. The Opagio Valuator uses this method for its detailed intangible asset valuations.

Note: Replacement cost sets a floor, not a ceiling. It captures the cost to recreate, not the value in use. It is most effective when combined with income-based methods to show that your assets are worth significantly more than their replacement cost — proving you have created real intangible value.

Best for: Deep-tech, AI/ML, and IP-heavy startups. Also valuable in due diligence and acquisition scenarios.

Method 6: Intangible Asset Sum (Opagio Proprietary)

Opagio's proprietary method values each category of intangible asset independently, then sums them to produce a total intangible asset valuation. Categories include:

1

Technology Capital

Proprietary software, patents, AI/ML models, trade secrets. Valued using Relief from Royalty or Replacement Cost.

2

Customer Capital

Customer relationships, contracts, backlog, loyalty programmes. Valued using Multi-Period Excess Earnings.

3

Brand & Marketing Capital

Brand names, trademarks, domain names, digital brand equity. Valued using Relief from Royalty.

4

Human & Organisational Capital

Assembled workforce, culture, management systems, training. Valued using Replacement Cost.

5

Data & Digital Assets

Proprietary datasets, digital platforms, network effects, user communities. Valued using Cost or With-and-Without.

Key Takeaway: The Intangible Asset Sum provides a bottom-up valuation that explains why a startup is worth its price — not just that it is. This is the method that bridges the gap between what founders have built and what investors are being asked to pay.

Best for: Any stage where founders want to provide a comprehensive, evidence-based valuation narrative. Particularly powerful at Series A+ and in exit preparation.
