What it means
Think of a term sheet as the deal in outline. It typically runs to two to six pages and covers valuation, the amount being invested, what the investor receives, governance rights and what happens if things go wrong.
The document matters far more than its length suggests. Whatever is agreed at term sheet stage is very hard to reopen later, because both parties treat it as settled and revisiting it reads as bad faith.
In a venture round the economic terms revolve around valuation and share class. Pre-money valuation plus the new money equals the post-money valuation, and the investor's percentage is simply the investment divided by that post-money figure.
The control terms are where inexperienced founders tend to lose ground. Board composition, veto rights over budgets and future fundraising, and information rights can matter more in practice than a few percentage points of ownership.
Protective economics such as liquidation preference deserve close reading. A 1x non-participating preference means the investor takes back its money or converts to ordinary shares, whichever is better, while a participating preference lets the investor do both.
Outside venture capital the shape is much the same. A lending term sheet sets out amount, tenor, margin, fees, security and covenants, while an acquisition term sheet, sometimes called heads of terms, fixes price, structure and conditions before due diligence begins.
In practice
Real-world examples
Example 1
A seed-stage analytics company signs a term sheet at a $6 million pre-money valuation for $1.5 million of investment. Legal drafting takes six weeks, and the only material change from the term sheet is the wording of the information rights clause.
Example 2
A mid-market manufacturer receives heads of terms from a trade buyer offering $22 million, of which $4 million is deferred over two years and linked to earnings. The seller negotiates the deferred element down to $2.5 million before signing, knowing that number would be far harder to move later.
Example 3
A property developer signs a lending term sheet for a $15 million facility at 4% over the reference rate, with a 1% arrangement fee and a covenant capping the loan at 60% of valuation. The sheet is non-binding on the amount but binding on the $50,000 of costs the developer must pay if it walks away.
Think of it
A term sheet is like the floor plan you draw with an architect before building a house. It lets you agree on the number of rooms and the general layout before anyone starts pouring concrete.
Formula
Calculation
Post-money valuation = pre-money valuation + new investment. Investor ownership = new investment / post-money valuation.
A founder-owned company agrees a term sheet at a pre-money valuation of $8,000,000 with a $2,000,000 investment. The post-money valuation is $8,000,000 + $2,000,000 = $10,000,000, and the investor's stake is $2,000,000 / $10,000,000 = 20%.
The term sheet also requires a 10% employee option pool measured on the post-money share count and created before the investment lands. That pool represents $1,000,000 of the $10,000,000 and comes entirely out of the existing shareholders, so the founders fall from 100% to 100% - 20% - 10% = 70%.
The real price of that clause becomes visible if you recalculate. The founders' 70% of a $10,000,000 company is worth $7,000,000, whereas without the pre-money pool they would hold 80% worth $8,000,000, so the pool cost them $1,000,000 of value while the headline valuation never moved.Case study
Seen in the real world
This is an illustrative and fictional example. Verity Sensors, an invented hardware start-up, received two term sheets in the same week, each offering $3,000,000 of investment. One valued the company at $12,000,000 pre-money with a 2x participating liquidation preference; the other offered $9,000,000 pre-money with a 1x non-participating preference.
The founders instinctively preferred the higher valuation. Modelling a sale at $30,000,000 showed why that instinct was wrong. Under the first sheet the investor owns 20% of the $15,000,000 post-money company and would take 2 x $3,000,000 = $6,000,000 first, then 20% of the remaining $24,000,000, which is $4,800,000, for a total of $10,800,000 and leaving $19,200,000 for the founders.
Under the second sheet the investor owns 25% of the $12,000,000 post-money company and takes the better of its $3,000,000 back or 25% of $30,000,000, which is $7,500,000, leaving the founders $22,500,000. The lower headline valuation was worth $3,300,000 more to the founders, and the illustrative lesson is that valuation is only one of a term sheet's economic terms.
Watch out
Common mistakes
- Treating a term sheet as harmless because it says non-binding, when the commercial terms inside it are almost never renegotiated afterwards.
- Focusing on valuation alone while skimming liquidation preference, option pool sizing and board control.
- Signing an exclusivity clause with no end date, which leaves a seller unable to talk to other buyers while diligence drags on.
Questions
People also ask
Is a term sheet legally binding?
Mostly no, but specific clauses such as confidentiality, exclusivity and who bears costs are usually drafted to bind, so read carefully which parts survive.
How long should a term sheet take to negotiate?
For a straightforward funding round one to three weeks is normal, and anything longer usually signals a mismatch on price or control that is better surfaced early.
What is a pre-money option pool and why does it matter?
It is an employee share pool created before new money arrives, and because it is carved out of the existing shareholders it quietly lowers the real valuation the founders receive.
