Startup Valuation Glossary 2026: 40 Key Terms

This startup valuation glossary defines the 40 terms you hit across a raise, in the order you meet them: pre-money and post-money valuation, the valuation cap on your SAFE, liquidation preferences on the term sheet, and the dilution math on your cap table. Two 2026 anchors are built in, starting with the median founder keeping about 56% at seed.

Most valuation glossaries are alphabetical dumps. This startup valuation glossary is a map of the raise instead: the 40 terms below are grouped by when you actually hit them, from setting your number, to the SAFE, to the term sheet, to the cap table, to the exit.

Each definition is written to be quoted verbatim, by you in a founder chat or by an answer engine. Two 2026 realities are built into the entries that matter: how little of your own company you keep by Series A, and how common down rounds have become. Both are sourced inline below. Read it in order once, then jump to the phase you are in and check your ask against seed valuation benchmarks for 2026.

What is a valuation cap?

A valuation cap is the maximum company valuation at which your SAFE or convertible note converts into equity, regardless of the priced round's actual valuation. Raise on a $10M cap, then price the round at $20M, and your early investors still convert as if the company were worth $10M, roughly doubling their shares per dollar versus new investors. The cap is the reward for early risk. Caps held relatively stable through Q1 2024 even as priced valuations moved (Carta).

Terms for setting your number

Before any paper exists, you argue over pre-money vs post-money valuation and how many fully diluted shares that price buys. These eight terms are the vocabulary of that first negotiation.

• Pre-money valuation: What your company is worth before the new investment goes in. It is the number you negotiate; everything else is derived from it. For a reference point, the median European early-stage valuation was €4.4M in H1 2024 (PitchBook).
• Post-money valuation: Pre-money plus the money raised. A $16M pre-money on a $4M round is a $20M post-money, and the investor owns 4/20, or 20%.
• Pre-money vs post-money: Which number a term is quoted against decides who absorbs the option pool and how much you own after close. Confirm it in writing.

• Fully diluted shares: Every share that exists if all options, warrants, and convertibles convert. It is the correct denominator for ownership percentages in a raise (Carta).
• Cap table: The ledger of who owns what, by share count and percentage, measured fully diluted.
• 409A valuation: An independent appraisal of your common stock's fair market value, used to set option strike prices, deliberately lower than your preferred (VC) price.
• Revenue multiple: A valuation shortcut, ARR times a market multiple. A sanity check, not a negotiating anchor at seed where revenue is thin.
• Comparables (comps): Recent financings of similar companies at your stage and sector, used to justify your ask.

Terms on your SAFE and convertibles

The valuation cap definition above lives inside an instrument, and these seven terms are the words on the SAFE itself. Get them right before you sign: the SAFE vs priced round choice sets your dilution for 18 months.

• SAFE: Simple Agreement for Future Equity. A short contract that converts into shares at your next priced round instead of pricing the company today.
• Post-money SAFE: The Y Combinator standard and the format you will most often see; it states the investor's exact ownership at conversion, which makes dilution predictable (Carta). See pre-money vs post-money SAFE.
• Pre-money SAFE: The older format where dilution from other SAFEs is shared, so your final ownership stays fuzzy until conversion.
• Discount rate: A percentage, commonly 10-20%, off the priced-round price that a SAFE investor gets for coming in early. It applies instead of the cap, whichever is better for them.
• MFN (most favored nation) clause: A term that lets an early SAFE holder adopt the best terms you later grant anyone else. Details in the MFN clause in a SAFE.
• Convertible note: A SAFE's older cousin, debt that converts to equity, carrying interest and a maturity date the SAFE dropped.
• Conversion: The moment a SAFE or note becomes actual shares, at the priced round, using the better of cap or discount for the holder.

Term-sheet terms that decide your economics

The term sheet is where a liquidation preference, a board seat, and your option pool get set, and where founder-friendly and founder-hostile terms diverge. These nine words carry most of the money.

• Term sheet: The non-binding summary of a priced round's economics and control terms. Signing it starts diligence, not the wire.
• Priced round: A financing that sets an actual per-share price and issues preferred stock, usually Series Seed or Series A.
• Lead investor: The fund that sets the terms and price and usually takes the largest check plus the board seat. Everyone else follows the lead.
• Preferred stock: The share class VCs buy. It sits above common (your shares) and carries the rights below.
• Liquidation preference: The guarantee that preferred holders get their money back first at an exit, before common. Standard is 1x non-participating; anything more is a red flag at seed.
• Participating preferred: A harsher preference where the investor takes their money back and also shares the rest with common. Push back at seed.
• Anti-dilution provision: Protection that re-prices an investor's shares down if you later raise at a lower price. Broad-based weighted average is normal; full ratchet is punitive.
• Pro rata rights: The investor's right to buy enough in future rounds to keep their percentage. Expect your lead to want it.
• Option pool (ESOP): Shares reserved for future employees. When it is created pre-money, founders pay for it in dilution, not investors.

Cap-table and dilution terms

Every share you issue moves these seven numbers, and they compound round over round. This is where a good headline valuation quietly turns into a smaller stake than you expected.

• Dilution: The drop in your ownership percentage each time new shares are issued. Walk the numbers in dilution at seed.
• Option pool shuffle: Creating or topping up the option pool before the money goes in, so the dilution lands on founders, not the new investor. Negotiate the size, not just the price.
• Founder ownership: The founding team's fully diluted stake. Median is about 56% at seed and 36% by Series A (Carta); use it to sanity-check your own cap table.
• Vesting: Earning your own shares over time, typically four years, so a co-founder who leaves early does not walk with a full stake.
• Cliff: The minimum tenure, usually one year, before any vested shares are earned. Leave before the cliff and you get nothing.
• Acceleration: A clause that vests unearned shares on an event, usually an acquisition (single trigger) or an acquisition plus termination (double trigger).
• Waterfall: The payout order at exit: preferences and participation first, common last. It decides what your equity is actually worth.

Down-round, bridge, and exit terms for 2026

When the market tightens, this vocabulary shows up on your term sheet, and in 2026 it shows up more often than founders expect. These eight terms cover the scenarios nobody plans for.

• Down round: A raise at a lower valuation than your last. Flat and down rounds were 28.4% of US deals in H1 2024, so this is no longer an edge case (PitchBook).
• Flat round: A raise at the same valuation as your last. Not a failure, often a pragmatic bridge in a tight market.
• Bridge round: A small raise, usually a SAFE or note, to reach the next priced round or a milestone.
• Cram down: A punitive recapitalization where existing investors force terms that heavily dilute non-participating holders, often founders and early angels.
• Pay-to-play: A term forcing existing investors to join a new round or lose their preferred rights. Common in down rounds.
• Drag-along: A clause that forces minority holders to go along with a sale the majority approves. It stops one holdout from blocking an exit.
• DPI (distributions to paid-in): Cash actually returned to a fund's investors divided by cash they put in. It is the number your VC's own investors judge them on.
• MOIC (multiple on invested capital): The total value of an investment divided by the amount invested, realized or not. A 5x MOIC means five dollars out for every one in.

From your number to a funded round

Knowing every term on this page still only gets you to a number. The other half of the job is running enough of the right investor conversations in parallel that a second term sheet appears, because a competing offer is what moves the valuation, not a better argument about your pre-money. Causo matches you to the investors most likely to fund your stage and sector and drafts the outreach, so you can run that many conversations without spending three weeks list-building. Once an offer lands, revisit the liquidation preference and option-pool entries above, where a good headline number quietly gets worse.

FAQ

What is a valuation cap and how does it work? A valuation cap is the highest company valuation at which your SAFE or convertible note converts into equity. If you raise on a $10M cap and the priced round comes in at $20M, your early investors convert as though the company were worth $10M, doubling their shares per dollar versus new investors. The cap protects early backers for taking on more risk. It is the single most important economic term on most seed-stage SAFEs.

What's the difference between pre-money and post-money valuation? Pre-money is your company's value before the new investment; post-money is pre-money plus the money raised. A $16M pre-money on a $4M round makes a $20M post-money, and the investor owns 4/20, or 20%. You negotiate the pre-money, but the post-money is what sets ownership, so always confirm which number a term is quoted against.

What does 'fully diluted' mean on my cap table? Fully diluted means counting every share that would exist if all options, warrants, and convertible instruments converted into stock, not just the shares issued today. It is the correct denominator for measuring ownership percentages during a raise, which is how Carta treats it for dilution math. A percentage quoted on issued shares alone will overstate what you actually own.

What is a down round and how does it affect founders? A down round is a financing at a lower valuation than your previous one. It dilutes founders more per dollar raised and can trigger anti-dilution provisions that hand earlier investors extra shares. Down rounds are not rare anymore: flat and down rounds made up 28.4% of US VC deals in H1 2024, per PitchBook. The practical damage depends on whether your prior term sheet used weighted-average or full-ratchet anti-dilution.

How does a SAFE valuation cap change my ownership after conversion? The cap sets the price your SAFE converts at, so a lower cap means the investor gets more shares and you keep less. On a $10M cap, a $500K SAFE converts into roughly 5% of the company; if the priced round values you at $20M, that investor still converts at the $10M cap, taking about twice the equity a new $500K check would buy. Stacking several capped SAFEs compounds this, so model total SAFE conversion before you sign the priced round.
