In Q1 2026, an AI foundational model startup raised its Series A at a median valuation of $300 million. A non-AI startup at the exact same stage raised at $55 million, according to Carta’s latest State of Private Markets report. Same round. Same paperwork. A more than five-times gap in startup valuation.
That gap is the clearest proof of something we tell every founder who walks into RunwayTeam: valuation isn’t calculated. It’s negotiated. And if you don’t understand how to value a startup - what actually moves the number an investor puts on the table - you’re walking into that negotiation blind.
We’ve built the financials and fundraising strategy behind 600+ raises. Here’s what actually sets your valuation, the methods investors use to defend it on paper, and how to build a number that holds up when they push back.
What Startup Valuation Actually Means
Startup valuation is the dollar figure that investors and founders agree your company is worth at the moment of a funding round. It isn’t your revenue, it isn’t your assets, and it’s rarely tied to what you could sell the company for today. It’s a forward-looking number - a bet on what the company could become, priced into the present.
Every valuation conversation eventually boils down to two numbers. Pre-money valuation is the company's value before the new investment closes. Post-money valuation is pre-money plus the new capital raised. If your pre-money is $8 million and you raise $2 million, your post-money is $10 million - and the new investor owns 20% of the company ($2M of $10M).
That relationship is the skeleton of every valuation conversation. Methods, comparables, and narrative all exist to justify where the pre-money number lands - not to replace this math.
Unlike a public company, there’s no market price updating by the second. A startup’s valuation of a startup is set discretely, round by round, and only becomes real when money actually changes hands. Between rounds, the number is theoretical - useful for cap table planning and option pricing, but not a verified fact until the next round prices it again: up, flat, or down.
Why Early-Stage Valuation Is Different
At later stages, valuation has anchors such as revenue multiples, EBITDA, and discounted cash flow. At pre-seed and seed, those anchors barely exist. Most early-stage companies have little or no revenue and no reliable cash flow to discount. There’s nothing for a spreadsheet to compute.
That’s why early valuation isn’t really a calculation. It’s a negotiation shaped by the round size you need, the ownership investors want, how many other investors are competing for the deal, and how convincingly you can tell the story of what this capital unlocks. Two startups with near-identical traction can land on very different valuations because one founder walked in with comparable data and a tight narrative, and the other walked in with a number pulled from a blog post.
This is also where founders get the order of operations backward. The valuation isn’t the starting point of your fundraise - it’s the output. Get your round size, target ownership, and narrative right first, and the valuation follows. That sequencing is exactly what we work through in fundraising strategy sessions, before a client ever puts a number on a slide. Chase a valuation number first, and you build a pitch that has to justify a conclusion rather than support one.
How Investors Actually Set Your Valuation
Start with the math every investor runs first, before any method, before any model. They decide how much they want to invest and how much ownership they want for that check. Divide the round size by the target ownership percentage, and you get the post-money valuation:
Round size ÷ Target ownership % = Post-money valuation
A $2 million raise at a 20% target ownership price valued the company at $10 million post-money and $8 million pre-money. Investors don’t usually start from “what is this company worth” in the abstract. They start from “how much do we want to own, and how much do we want to write.”
That ownership target isn’t arbitrary either. Across the last seven quarters, founders have consistently sold around 20% of the company at the seed stage, according to Carta’s State of Seed data - a remarkably stable figure even as round sizes and valuations have moved sharply. Some AI-heavy rounds compress that toward 10%, but 20% remains the working default most investors anchor to.
Once that math sets a starting range, the qualitative factors decide exactly where inside it you land:
Comparable recent rounds in your sector and stage - real deals, not aspirational ones.
The strength and track record of the founding team.
Early traction or demand signals, even pre-revenue.
The size of the market you’re credibly chasing.
How many other investors are competing for the deal? A round with three term sheets prices very differently from a round with one.
The Main Valuation Methods (and When They Fail)
Once the ownership math sets a rough range, investors - and increasingly, well-prepared founders - use a handful of formal methods to defend the number on paper. None of them is precise. All of them are useful for building a credible narrative around your valuation.
For most pre-seed and seed founders, DCF is closer to theater than analysis - there’s no reliable cash flow to discount yet. The methods that matter most early are the Scorecard and VC methods, used alongside genuine comparables. From Series A onward, multiples and DCF start to carry real weight as revenue becomes the anchor rather than the narrative.
The mistake we see most often: founders treat the method as the source of truth, when it’s really just the language used to defend a number that ownership math and negotiation already roughly set.
Valuation by Stage: Pre-Seed to Series A
Benchmarks shift fast, and they shift by quarter, not by year. The figures below are from Carta’s most recent reporting and should be read as a directional range, not a rule.
Pre-seed: Typically priced in the low-to-mid single-digit millions on a post-money basis, financed almost entirely through SAFEs rather than priced equity. Convertible notes have fallen to a record-low share of pre-seed deals.
Seed: Median post-money valuation reached $24 million in Q4 2025, up from $18 million a year earlier and $16 million two years before that - a new all-time high, and still climbing.
Series A: Median post-money valuation hit $78.7 million in Q4 2025, up 37% year-over-year from $57.5 million. At both stages, the AI premium we opened with is now the single biggest driver of where in that range a specific company lands.
Early-stage SaaS is the one category bucking the broader trend - valuations there actually softened in Q1 2026 even as the wider market warmed, a shift worth watching if you’re building in the space. If you’re raising a SaaS round, our SaaS pitch deck guide covers the metrics investors are stress-testing harder than ever right now.
Despite valuations climbing, dilution hasn’t spiked. Median dilution at seed and Series A has held in the 19-20% range - close to the historical norm - and down rounds have fallen to roughly 11% of deals in Q1 2026, the lowest rate since before the 2021 boom, per Carta. Higher valuations and lower dilution are occurring simultaneously, largely because round sizes are growing in step with the price.
How to Justify Your Number (Not Just Pick It)
A valuation only survives first contact with diligence if you can defend it with something more substantial than ambition. Three things do the defending.
A financial model with real assumptions
Not a hockey-stick revenue line pulled from nowhere, but a model where every input - pricing, conversion, churn, hiring pace - is something you can explain and stand behind in a follow-up call. This is the single biggest differentiator between a valuation investors accept and one they negotiate down hard. We cover exactly what belongs on that page in our guide to the financials slide.
Comparable evidence
Two or three recent, similar rounds you can point to - not as proof your number is right, but as proof it isn’t invented. “Comparable Series A rounds in our category priced between $60M and $90M post-money this year” is a sentence that changes a negotiation.
A use-of-funds story that earns the number
Investors aren’t just pricing what you’ve built - they’re pricing what this specific check unlocks. A vague “$3M for growth” invites a lower offer. A precise breakdown tied to milestones earns the higher end of your range. We break down exactly what that slide needs in Use of Funds Slide: The 5 Elements Investors Want to See.
A valuation is only as strong as the model behind it. If your financial model isn’t built yet - or isn’t built to hold up under investor questions - that’s where we’d start.
Common Valuation Mistakes
Anchoring too high without evidence. A number you can’t defend doesn’t just risk rejection - it stalls the round while investors quietly pass, and sets an unrealistic bar your next round then has to clear.
Ignoring the option pool. A 10-20% pre-money option pool is typically carved out of the founders’ side of the cap table, not the new investor’s. Skip this math, and your actual dilution is higher than the headline number suggested.
Treating a higher valuation as automatically a win. An inflated valuation you can’t grow into is a down-round risk wearing a good mood. The number that lets you raise your next round up beats the number that maximizes this one.
No evidence behind the ask. Founders who walk in with a number but no comparables, no model, and no use-of-funds logic are negotiating from a position investors can see straight through.
Confusing valuation with value. The valuation is a financing mechanism, not a scoreboard. The company that actually builds something defensible outlasts the one that simply priced its last round well.
FAQs
How is a startup valued?
An early-stage startup is valued mostly through negotiation, not a formula. Investors start with how much you’re raising and the ownership they want (often around 20%), cross-check against recent comparable rounds, then adjust for team, traction, market size, and the level of competition for the deal. Methods like the Scorecard, Berkus, and VC method formalize that judgment, but the number is ultimately what an investor will pay for the round.
What is the difference between pre-money and post-money valuation?
Pre-money valuation is what your company is worth before the new investment. Post-money valuation is the pre-money figure plus the new money raised. If your pre-money is $8M and you raise $2M, your post-money is $10M, and the new investor owns 20% ($2M of $10M).
How do you value a startup with no revenue?
With no revenue, valuation leans on qualitative signals and market norms rather than financial multiples. Investors weigh the strength of the team, early traction or demand signals, market size, and comparable pre-revenue rounds. The practical anchor is still the ownership math: the round size divided by the investor’s target ownership sets the post-money valuation.
What are the main startup valuation methods?
The most common early-stage methods are the Scorecard method, the Berkus method, comparables (benchmarking to similar recent rounds), and the VC method (working backward from a target exit and return). Discounted cash flow exists but is rarely meaningful before predictable revenue. Most investors blend a few of these rather than relying on one.
Is a higher valuation always better?
No. A valuation that’s too high relative to your traction can stall your round, set an unrealistic bar for the next one, and increase down-round risk. The goal is a defensible valuation you can support with evidence and grow into, not the biggest possible number.
What is a typical valuation at the pre-seed or seed stage?
Valuations vary by market, geography, and sector, but pre-seed rounds commonly price in the low single-digit millions, and seed rounds reached a median post-money valuation of $24 million in Q4 2025, according to Carta. These figures shift every quarter, so benchmark against current data rather than older rules of thumb.
