In a term-sheet negotiation you will have to give something up. Founders spend that concession on the number, defending the valuation to the last point and waving through the rest as boilerplate. Your best investor is doing the opposite. He is letting you win the price so he can quietly win one clause: the right to follow on, called pro rata.
Read that clause as what it is. It is the right, not the obligation, to buy more of your company in the next round to hold his percentage.1 That is a call option, and you are the one writing it. The decision this article helps you make is narrow and it recurs on every sheet: when you must concede something, concede the thing you can price, and never hand over the option by accident.
Why these three lenses
This is a question about the value of a right that only pays in the future, so a single model will mislead you. A term-sheet checklist tells you the clause exists. It cannot tell you what it is worth to the person across the table, which is the only thing that lets you trade it well.
Three lenses, each catching what the others miss. First, option value: what the follow-on right is worth as a call the investor holds on your future equity. Second, the winner’s curse: why a good investor wants that right more than he wants a cheaper entry price. Third, network centrality: why the same right, granted to too many people, quietly locks your next round shut. The three span three kinds of outcome, a random-payoff lens, an equilibrium lens, and a complex-system lens, so they fail in different directions and you can lean where they agree.
1. The option: you are writing a call on every good year ahead
Strip the language away. Pro rata lets an investor put more money in later, at a price someone else will set, only if he wants to. He exercises when your next round is up and skips it when you stumble. A right to buy, exercised only in the good states, priced later: that is a call option, and its holder is your investor.
The value of a call rises with two things. It rises with the dispersion of the underlying, how wide the range of your possible outcomes is. And it rises with tenor, how many future rounds sit between now and your exit. Early companies on this continent are long on both. Outcome dispersion is enormous, and the road from seed to any liquidity runs through several rounds over many years. That combination makes the follow-on option fat, and a fat option is expensive to write.
Now see it from his fund. A venture manager does not make his return on the median company. He makes it by putting more money into the few that break out, which is why reserving capital to “double down on the winners” is treated as a core skill of a seed-stage investor rather than an afterthought.2 Funds hold back thirty to forty percent of their capital for exactly this, deploying only the rest into first checks.3 The pro rata right is what lets those reserves land in your company instead of a stranger’s. Take the right away and his reserves have nowhere to go.
Pro rata is not a courtesy you grant. It is a call option you write, and its premium is paid in the one outcome you are raising money to reach. A dollar of entry price is linear and settled once. The option pays precisely in the upside, the state that decides his whole fund, which is why he will trade you the number to hold it.
Assumes: your outcome distribution is wide and several rounds separate you from any exit, so the right has real tenor.
Fits because: a right to buy later at a price set later, exercised only in good states, is the definition of a call.
Breaks when: your category has no next-round market, so there is nothing to exercise into and the option is worth nothing.
Counteracts: the founder reflex that defends price and gives structure away.
May reinforce: founder optimism, since a founder sure of the upside underprices the very option that is dear in the upside. Behavioral fold: that optimism is the mispricing this lens already predicts, so it earns no separate card.
2. The curse: why he wants the right more than a discount
A cheaper price today is worth something, so why does your sharpest investor trade it away for a clause? Because your next round is a common-value auction, and he has read the room better than you have.
In a common-value auction, several bidders chase one prize whose true worth nobody knows, and each bids off a noisy private read. The bidder who wins is usually the one whose read was highest, which means the winner has systematically overpaid. Richard Thaler set this out plainly: fill a jar with coins, auction it to a room, and the winning bid reliably exceeds what the coins are worth.6 The name for it is the winner’s curse, and pricing a private company two rounds out is a textbook case of it.
The follow-on right is a hedge against that curse. It lets the incumbent wait until a new lead has done the diligence, taken the risk, and set the price, and then buy in at that mark. He gets to invest in your winner on someone else’s price discovery, which is worth more to him than any discount you could have handed him at the seed. He sidesteps the single largest risk in later-stage bidding, overpaying for the company he already knows, and he does it by holding a clause you thought was soft.
That is the trade you are actually in. He values the right above the number, so a rational split hands you the number and keeps him the right. Which means the concession is worth naming out loud: if you must give ground, give the thing he values and take, in exchange, the thing you value, a clean preference or a board you can live with.
Assumes: your value in the next round is genuinely uncertain and several parties will bid on a shared read of it.
Fits because: the follow-on right converts a blind bid into a bid placed after a new lead reveals the price, removing the curse.
Breaks when: the next round has a single obvious price and no real contest, so there is no curse to hedge and the right is worth less.
Counteracts: the assumption that a discount today and a right tomorrow are interchangeable currency.
May reinforce: the option lens, since dodging the curse is one more reason the call is dear in exactly the states that matter.
3. The network: how small rights sum to a shut door
Everything so far argues the right is valuable, which could read as a reason to hoard it. The third lens is the check on that instinct, and it is where founders do the real damage.
A single pro rata grant is trivial. The problem is that they add up. If your early angels, your seed fund, and two DFIs all hold the right to hold their percentage, then a large slice of your next round is spoken for before a new lead sees the deal. Each grant is a small edge on the cap table. Together they make your existing holders the hubs that all future money must route through, and a new lead who cannot get a meaningful stake will not lead. Super pro rata, the right to increase and not merely maintain, is worse: it lets an early holder expand at the exact moment you need room, and it “severely constrains your ability to bring in new investors.”7
Individually reasonable grants sum to a foreclosed Series A. That is the emergent failure: no single clause is unfair, and the aggregate locks the door. In the African case the door is heavier, because the new lead you need at Series A is often a foreign fund that already requires a local co-investor to share the checking cost, and it will walk if the cap table leaves it no room to earn its ownership.
So the right you should protect for your best investor is the same right you must ration against everyone else. Grant full pro rata deliberately, to the one lead whose capital and signal you actually want in the next round.7 Withhold it, cap it, or sunset it for the rest. The pro rata clause travels bundled with information and consent rights reserved for “major investors,” so who you grant it to is also who sits closest to your governance. The same decision about who holds the right settles who holds the influence, which is why governance folds into this lens rather than standing as its own card.
Assumes: several holders carry pro rata and their claims stack against a fixed next-round size.
Fits because: a new lead needs a threshold stake to justify leading, and central incumbents crowd it out.
Breaks when: your round is oversubscribed enough to satisfy every existing right and still seat a new lead, which is rare.
Counteracts: the hoarding instinct the first two lenses could feed.
May reinforce: the option lens in reverse, since a foreclosed company cannot raise the round the incumbent’s own option was written on.
GEER: the levers, from a pen stroke to a real trade
Ordered cheapest and most reversible first. Stop at the point where the concession starts costing you something real, and make that one on purpose.
- Relabel the term in your own model before the meeting. Write “call option I am granting” next to the pro rata line, not “standard investor right.” Costs a pen stroke and changes how you negotiate every clause after it.
- Attach a major-investor threshold. Limit pro rata to holders above one to two percent of fully diluted equity. It strips the right from the long tail of small holders who cannot meaningfully follow on anyway, and it is a drafting change, fully reversible until signed.7
- Sunset or round-limit the right. Let it expire after the next round or after a fixed term rather than run perpetual. Standard, cheap, and it keeps your later cap table free.7
- Grant full pro rata to your lead, on purpose. Give the complete right to the one investor whose follow-on capital and name you want in the next round, and to no one else by default. This is the deliberate trade the whole piece is about.
- Spend it as your concession. When the deal needs a give, offer pro rata to the investor who values it, and take price, a clean 1x non-participating preference, or board simplicity in return. Only reach this lever once you have priced the option, because past here you are trading something dear.
RADAR: what to settle before the sheet is signed
A dated plan for both sides of the table. Anchors are relative to the day the term sheet lands.
DO NOW, by T+3. Founder: price the follow-on right before you send a single counter, using its two drivers, how wide your outcomes are and how many rounds you have left. Investor: decide the one term you actually need and ask for it in the open, rather than bundling it into a list where the founder cannot see which clause you care about.
HEDGE, by T+14. Founder: put in the major-investor threshold and a sunset as cheap tail insurance against foreclosure, before you know which holders will matter. Investor: accept a round-limited right instead of a perpetual one. A founder you foreclose cannot raise the round your option was written on, so the limit protects your own downside as much as his.9
DEFER AND TRIGGER, by T+28. The irreversible move is conceding pro rata to a specific investor, so pre-commit the trigger rather than deciding in the room. Founder: grant the full right to your lead only when the sheet clears a written bar you set in advance, say a 1x non-participating preference and a board you chose. Trigger: a term sheet that meets the bar, in writing. Investor: exercise super pro rata only when the company still has room for a new lead. Trigger: the next-round lead is secured, not merely hoped for.
CHAIN: what usually happens to the party who does not price the clause
Match the reference class on structure, not on setting. The right comparison is not “African seed rounds.” It is any deal where two parties split a bundle of rights and one of them values a low-salience clause far more than the other prices it. The publisher’s option on an author’s next book. The team option year in an athlete’s contract. The renewal right buried in a commercial lease. Across that class the pattern is steady: the surplus moves to the side that priced the quiet term, and it moves at the expense of the side that treated it as boilerplate.
The base rate here runs against you. Reserve capital is deployed toward winners on purpose. Managers “allocate the greatest reserves to the highest yielding deals” and rebalance as they learn, which means the follow-on right gets used hardest exactly on the companies where your dilution stings most.4 In one worked fund, concentrating reserves into the three strongest companies returned an aggregate 8.6 times on those follow-ons.5 The right is where a good chunk of his return is manufactured, on your cap table, not a decorative line on the sheet.
Two present-state modifiers push the African case further off the base rate. First, few local angels bother to ask for pro rata, so founders grant it broadly when they do, treating a fat option as a free courtesy. Second, the thin follow-on market means the incumbent who does hold the right faces little competition to exercise it, which raises its value to him and lowers your leverage to reclaim it.
Subtract the counterfactual before you blame the clause. A weak company fails to raise its next round whether or not it granted pro rata. The grant’s true cost is only the rounds where you were fundable and got foreclosed anyway, or where you traded the option for nothing because you never priced it. That, not every hard raise, is the damage to lay at this term’s door.
Matrix-break flag. The models assume a priced next round exists to exercise into. If your category has no Series A market at all, the option is worthless to the investor, the winner’s curse has no auction to occur in, and foreclosure cannot happen because there is no lead to foreclose. In that world the whole trade inverts: concede pro rata freely and extract maximum price, because you are giving away an option that can never pay. Check which world you are in before you fight for the clause.
Where this reading runs out
The three lenses price a right. They do not price a relationship. Granting broad pro rata to a merely adequate investor can buy you a bridge in a bad month, or peace on a board, and the option math is blind to both. The lenses also assume the investor is rational about his own call, when some will demand the right out of habit and never fund it, and some will read your refusal of it as a red flag that chills the round before it opens. And they assume you know your own outcome dispersion, the input the whole option value turns on, which at seed you do not.8 Even a fund’s own reserve logic is contested, with some managers arguing the follow-on option should be weighed against the plain opportunity cost of a fresh investment rather than reserved on reflex.9
None of that changes the one move that survives the ignorance. Before your next counter, write a single sentence: name the one term this investor most wants, and the one thing you will take for it. If you cannot fill that sentence in, you are negotiating the price while he negotiates the option, and you will lose the trade you did not know you were in. So write the sentence first, then send the counter.
