When a founder walks into the Tank and asks for $100,000 for 10%, they're claiming their company is worth $1 million. When that number can't be defended, the pitch usually turns into an argument about valuation instead of a conversation about partnership. Whether you're pitching Sharks, local angels or a friend who wants to invest, you need a valuation you can explain in two sentences.
Valuing an early-stage company is part science and part negotiation. There's no single correct number. But there are sensible methods, and using more than one gives you a range you can defend.
This guide is educational and isn't financial, tax or legal advice. For a real fundraise, work with a qualified advisor.
First, understand what a valuation is
A valuation is what an investor and a founder agree the company is worth at the moment of investment. It determines how much ownership an investor gets for their money:
Equity % = Investment ÷ Post-money valuation. At a $1,000,000 post-money valuation, $100,000 buys 10%.
For the basics of pre-money and post-money, see how valuation works on Shark Tank. You can test any of the numbers below in the valuation calculator.
Method 1: Revenue multiple
The most common shortcut for small consumer businesses. Multiply annual revenue by a multiple that reflects the business's quality and growth.
Worked example: Trailing 12-month revenue is $400,000. You choose a 2.5x multiple based on solid growth and 55% gross margins.
- $400,000 × 2.5 = $1,000,000
- An ask of $100,000 would be for about 10%.
How to pick a multiple
Multiples vary widely by industry, size and market conditions. Rather than relying on a single number, adjust up or down based on these factors:
| Pushes the multiple up | Pushes the multiple down |
|---|---|
| Fast year-over-year growth | Flat or declining sales |
| High gross margins | Low margins, high cost of goods |
| Recurring or repeat revenue | One-time purchases |
| Diverse channels and customers | One retailer or channel dominates |
| Protected IP or strong brand | Easy to copy |
| Profitable | Large losses |
Method 2: Earnings multiple
If the business is profitable, investors may value it on profit rather than revenue. This is closer to how many established small businesses are valued.
Worked example: Annual pre-tax profit (or a similar measure like EBITDA) is $150,000. Using a 5x multiple:
- $150,000 × 5 = $750,000
Notice that this can produce a very different number from Method 1. A company with $400,000 in revenue and $150,000 in profit is unusually profitable; one with $400,000 in revenue and a $50,000 loss can't use this method at all. That gap is why Sharks so often ask about profit right after sales.
Method 3: Comparables
Look at what similar companies were valued at when they raised money or were acquired. Public information on small private deals is limited, but you can find signals in startup databases, industry news, crowdfunding campaigns and, yes, televised pitches.
Shark Tank is a useful (if imperfect) source of comparables because founders state their ask on air. Watch pitches in your category and note the ask, the stated sales and the final offer. For example, food founders could study Daisy Cakes (Season 2), a bakery shipping Southern layer cakes nationwide, or Wild Squirrel Nut Butter (Season 3), both of which closed deals with Barbara Corcoran. Children's product founders might study SwimZip (Season 5) and LockerBones (Season 5), which closed deals involving Lori Greiner. Home product founders might look at Urbio (Season 4), a magnetic vertical garden system.
Two cautions: television deals reflect negotiations under unusual conditions, and on-air terms can change after due diligence. Use comparables to sanity-check a range, not to set a precise number.
Method 4: Needs-first (the dilution approach)
Many early founders work backwards from two questions: How much money do I need to reach the next milestone? And how much ownership am I willing to give up?
Worked example: You need $150,000 to fund a large inventory order and a marketing test. You're willing to give up 15% to 20%.
- $150,000 ÷ 15% = $1,000,000
- $150,000 ÷ 20% = $750,000
This gives a range of $750,000 to $1,000,000. Now check it against Methods 1 to 3. If your revenue is $80,000, a $1 million valuation is 12.5 times sales, which most investors would find hard to accept for a small consumer business. In that case, you might raise less money, give up more equity or wait until sales grow.
Pre-revenue businesses
Without sales, valuation is mostly a negotiation about potential and risk. Factors that matter include the founder's experience, intellectual property, prototype quality, letters of intent from buyers, waitlists and the size of the opportunity. Pre-revenue pitches face steep skepticism on Shark Tank, because there's little evidence customers will pay. If you're pre-revenue, often the best way to increase your valuation is to make your first sales.
Simple, low-cost businesses can prove demand quickly. I Want To Draw A Cat For You, a website selling custom hand-drawn cartoon cats, closed a deal with Mark Cuban in Season 3. Kisstixx, a paired-flavor lip balm, also closed with Mark Cuban that season. Neither needed to be complicated to get in front of investors.
Putting it together: a step-by-step process
- Gather your numbers: trailing 12-month revenue, growth rate, gross margin, profit or loss. See Know Your Numbers.
- Calculate a revenue-multiple range with a low, middle and high multiple.
- If profitable, calculate an earnings-multiple range.
- Find three to five comparables in your category and stage.
- Run the needs-first calculation for the money you need.
- Find the overlap. Where the ranges intersect is your defensible zone.
- Set your ask near the top of the zone and your walk-away near the bottom.
- Write the two-sentence explanation. For example: "We did $400,000 in sales last year, growing 80%, with 55% gross margins. At $1 million, we're valuing the company at 2.5 times trailing revenue."
Example summary
| Method | Inputs | Result |
|---|---|---|
| Revenue multiple | $400,000 × 2x to 3x | $800,000 to $1,200,000 |
| Earnings multiple | $120,000 × 5x to 7x | $600,000 to $840,000 |
| Comparables | Similar-stage brands in category | $700,000 to $1,100,000 |
| Needs-first | $150,000 at 15% to 20% | $750,000 to $1,000,000 |
| Defensible zone | Overlap of ranges | About $800,000 to $1,000,000 |
In this hypothetical, an ask of $150,000 for 15% ($1,000,000) is at the top of the zone, and a walk-away of about $150,000 for 19% (roughly $790,000) is near the bottom.
How investors will test your number
Expect any serious investor to challenge your valuation from several angles at once. They'll compare it to your trailing sales, ask what profit you made, question your growth assumptions and ask how you arrived at the figure. If you've done the work above, each question has a ready answer: the multiple you used, why it fits, the comparables you studied and the range you're comfortable with. Founders who can show their reasoning tend to have more productive negotiations even when investors disagree with the final number, because the discussion becomes about assumptions rather than about whether the founder is being realistic.
Common valuation mistakes
- Valuing on projections alone. Investors discount future sales heavily.
- Ignoring margins. $1 million in sales with 10% margins is worth far less than with 60%.
- Using a giant company's multiple. Public companies and venture-backed tech startups aren't comparable to most small consumer brands.
- Counting time and money spent. What you invested doesn't determine what the business is worth.
- No range. A single number leaves you nowhere to go in a negotiation.
Next, prepare for the negotiation itself with negotiation lessons from the Tank and review common pitch mistakes.
Reminder: these methods are simplified for education. Actual valuations depend on many factors and should be reviewed with a qualified professional.
Frequently asked questions
How do you value a startup with revenue?
A common approach is to multiply trailing 12-month revenue by a multiple adjusted for growth, margins and risk, then cross-check it with earnings multiples, comparable companies and the dilution you can accept.
How do you value a pre-revenue startup?
Pre-revenue valuation is mostly negotiation based on the founder's experience, intellectual property, prototype, signs of demand and market size. Making first sales is often the most effective way to support a higher valuation.
What is a good revenue multiple for a small business?
There's no universal number. Multiples vary by industry, growth, margins and market conditions. Faster growth, higher margins and recurring revenue generally support higher multiples.
How much equity should I give up for investment?
It depends on how much you need and your valuation. Divide the investment by the post-money valuation to get the equity percentage, and decide your acceptable range before negotiating.
