If you’re a first-time founder and an investor asks what your business is worth, you need to come ready with an answer before opportunity passes you by, and the formula is actually quite simple:
Work out what stage you’re at, run at least two of the five valuation methods that suit that stage, then build the case for the things that no formula measures. Your team, your proof, your momentum.
We’ll cover all the steps below:
Step 1: Work out what stage you’re actually at
Before you touch a formula, be honest about where you are Valuing a startup that hasn’t launched yet is a completely different exercise to valuing one that is consistently generating revenue. Proof of performance has weight that concept pitching can’t replicate, so you need another angle.
Pre-revenue, you have no trading history. Nothing to extrapolate from. Without a ‘cake’ investors can only value your ingredients: what you’ve built, what it cost, and how similar bets have gone in the space as of late. Don’t see this as underselling yourself, it’s simply meeting your business where it’s at.
Post-revenue however, you have numbers, so they can value the machine instead of the promise.
Are you pre-revenue or operating? / have customers paid you money? Yes or no. The answer knocks three of the five options off your list.
Step 2: The 5 startup valuation methods
These five methods come straight from the Startup Toolkit: A Step-by-Step Guide for Founders, written by our founder, Peter Deans, who spent decades as a financier sitting on the other side of that table.
1. Cost-to-Duplicate
What would it cost someone to build exactly what you’ve built, from scratch, today?
Add up development costs, prototype spend, IP, assets. Think of this as your base to market.
The catch is, this values your effort, not your upside. It ignores your brand, your customers and your growth entirely. Nobody builds a business to be worth what it cost them, so treat it as a baseline, not a target.
2. Book Value
Your net assets. Total assets, minus liabilities. This works for asset-heavy businesses with machinery, inventory or property on the books.
That said, most startups have almost nothing on a balance sheet. Your value sits in the idea, the code, the people and the traction, and none of that shows up here. If you’re a software startup, book value makes you look like you’re worth a laptop and some loose change.
3. Comparable Transactions
What did investors recently pay for startups like yours?
You look at similar businesses in your industry funded or acquired lately, and you triangulate. This is the market-rate method, and investors reach for it constantly. A great thing to note here is ‘similar’ is doing a lot of the work in that sentence. The same industry is not the same business.
4. Revenue Multiple
Your revenue (or your ARR), multiplied by a factor drawn from similar businesses in your sector. A great hybrid way to value.
KEY TAKEAWAY: the revenue multiple method does not work if you’re pre-revenue. Zero times any multiple is still zero.
5. Discounted Cashflow(DCF)
You forecast the cash the business will throw off, then discount it back to today’s money using an interest rate. It’s the most “proper finance” option on the list.
The catch: it’s far less common for a startup not yet generating revenue or cash flow. Forecasting cash flows for a business that’s never had any isn’t modelling. It’s fan fiction. And every assumption gets challenged.
Method | Works when | What it actually measures |
|---|---|---|
Cost-to-Duplicate | Pre-revenue | What you’ve spent so far |
Book Value | Asset-heavy businesses | What you own, minus what you owe |
Comparable Transactions | Any stage | What the market is paying |
Revenue Multiple | Revenue only | What your sales are worth |
Discounted Cash Flow | Predictable cash flow only | What your future is worth today |
Step 3: Never run just one
Investors commonly use more than one method. They’re looking at a ballpark figure, not hunting for a number. For example,three methods that land in the same neighbourhood brings confidence. Three methods that produce figures wildly apart, seed doubt. Run the exercise yourself before the meeting and you’ll never get blindsided.
The other factors
Whatever the methods spit out, the final valuation gets heavily influenced by factors no formula captures. These five do most of the work:
Factor | What investors are quietly checking |
|---|---|
The team | Can these people actually pull it off? |
Industry growth | Is the market they’re in getting bigger? |
Revenue potential | Can this grow AND make money? |
Proof-of-concept | Has anyone outside the building proved it works? |
Momentum | Is the line going up? |
Your team: A strong, experienced founding team is one of the biggest factors for startup investors, and it counts most when the business hasn’t started operating yet. They want a mix of leadership and management skills, relevant technical and industry experience, and ideally a track record of ventures that worked, lean in hard here if you’re pre-revenue.
Industry growth projections: Investors want to be in sectors that are growing. Thorough market analysis showing real trends, unmet needs and a sizable target audience makes the opportunity credible. A great business in a shrinking market is a hard sell.
Revenue and profit potential: Not revenue. Potential. Your number is shaped by how confident investors are in your road to growth and profitability.
Proof-of-concept: Any market validation moves your number. A working prototype, a successful PoC or pilot, positive customer feedback. It reduces perceived risk and proves your thing solves the problem you said it solves. This is why validating a product idea pays you back twice. Once in the build, once in the valuation.
Momentum: If you’re already trading, show the line going up and to the right. Customer acquisition climbing. Revenue growing. Strategic partnerships signed. Product milestones hit. Momentum is the difference between “this exists” and “this is going somewhere.”
“Businesses that can generate strong, continued year-on-year revenue growth become valuable businesses.” Peter Deans, author of Startup Toolkit: A Step-by-Step Guide for Founders
The market gets a vote too
Yep, just like the weather, Investment appetite and general market conditions change and influence valuations. In times of financial and economic stress, valuations are lower, even with all your same figures.
Know your range. Know your floor. Know when the number on the table is the market talking rather than your business.
Before your next investor conversation
1. Confirm your stage. Pre-revenue or operating.
2. Run at least two methods that suit it. Not one.
3. Write the qualitative case down. Team, market, potential, PoC, momentum. One page.
4. Have your cash flow forecast ready.
5. Decide your walk-away number before you’re in the room.
