Founders do not lose a company in one decision. They lose it in six decisions that each made sense at the time.
The six: a co-founder split with no vesting, a pre-seed cap set for speed, an ESOP pool created pre-money, a bridge note carrying full ratchet signed in 48 hours, a second pool created pre-money at Series A, and a recapitalisation accepted with a 2x participating preference. None of them is unusual. Together they take a founding team from 100% to 16.5% in three years, with the whole preference stack still ahead of them at exit.
Here is a three-year sequence with the arithmetic shown at every step. The numbers are synthetic. The mechanics are not. Model inputs are listed at the end so the table can be rebuilt or disputed.
Year 0. The split.
You start with 100%. You find a co-founder and split 60/40. No vesting schedule. No cliff. You are moving fast, and asking a co-founder to earn shares over four years feels like distrust.
It is not distrust. It is the difference between a partner who is required to stay and a shareholder who can leave in month nine holding 40% of everything built afterwards. The clause costs nothing while everyone stays. It only has a price when someone goes, and by then it cannot be added.
Year 1. Pre-seed.
Angels put in SAR 500k on SAFEs with a post-money valuation cap of SAR 3.3M. That is 15% at conversion. Quick close, no lead investor, no board structure negotiated properly.
The cap was set to close in a week. It also sets the price of the company for everyone who comes after, and it sells 15% before there is a product. A cap chosen for speed is still a valuation, and the next investor will read it as one.
Note what the share register says at this point: nothing has been issued. Founders hold 100% of issued shares. The 15% exists only in an instrument that has not converted yet, which is why the fully diluted view is the only one that matters.
Fully diluted, modelling conversion:
| Holder | Ownership |
|---|---|
| Founder 1 | 51.0% |
| Founder 2 | 34.0% |
| Angels (on conversion) | 15.0% |
Feels fine.
Year 1. Seed.
A VC leads at $2M for 20%, a $10M post-money valuation. The SAFEs convert. Standard terms: 1x non-participating liquidation preference, broad-based weighted average anti-dilution. And the clause founders skim past: a 10% ESOP created pre-money.
Pre-money pool creation means the pool is sized as 10% of the post-money company but carved out of the pre-money valuation. The new investor’s 20% is untouched by it. The dilution lands entirely on the holders who were already there, which at this stage means mostly you.
| Holder | Ownership |
|---|---|
| Founder 1 | 35.7% |
| Founder 2 | 23.8% |
| Angels | 10.5% |
| ESOP | 10.0% |
| Seed VC | 20.0% |
Still manageable.
Year 2. The bridge.
Growth is real but cash conversion is slow. Receivables build. Payroll is in three weeks. You need money fast, and everyone at the table knows it.
You take a convertible note. SAR 3M, 20% discount, no cap, converting at the next priced round. It also carries full ratchet anti-dilution on the shares it converts into. You sign in 48 hours because you have no alternative and no leverage.
The discount is the visible price. The ratchet is the one that matters, and it does nothing at all for two rounds. Anti-dilution protects the holder who was granted it, on the shares that holder owns, against a later round priced lower. It cannot reach backwards to reprice anyone else. A founder reading this clause in an emergency sees a term that costs nothing today. It is written to cost something on the worst day the company will have.
Year 2. Series A.
Revenue is growing. You raise $6M at $20M pre-money, a $26M post-money valuation. New money takes 23.1%. The seed investor exercises pro-rata inside that $6M, taking $1.5M of the round rather than adding to it. The bridge converts at its discount and takes its place on the table. The lead requires an ESOP refresh: another 5%, created pre-money again.
| Holder | Ownership |
|---|---|
| Founder 1 | 24.3% |
| Founder 2 | 16.2% |
| Angels | 7.1% |
| Seed VC | 19.4% |
| Series A lead | 17.3% |
| ESOP | 11.8% |
| Bridge note | 3.9% |
Nothing dramatic happened in this round. That is the point. Every mechanism worked exactly as documented.
Year 3. The recapitalisation.
Market conditions turn. Q3 revenue misses. The next money available is $4M at $3.2M pre-money, an 88% cut from the last post-money valuation. It comes with a 2x participating preference, senior to everything already issued.
At that price, the bridge’s full ratchet triggers. The bridge holder’s SAR 3M is repriced as though it had been invested at the recapitalisation price, and the additional shares are issued to make that true. The seed investor’s broad-based weighted average provides partial protection and produces far fewer shares. Common stock has no anti-dilution at all, which is the entire mechanism: protection is a right somebody negotiated, and the founders never did.
| Holder | Ownership |
|---|---|
| Recap investor | 50.8% |
| Bridge note | 10.2% |
| Founder 1 | 9.9% |
| Founder 2 | 6.6% |
| Seed VC | 7.9% |
| Series A lead | 7.0% |
| ESOP | 4.7% |
| Angels | 2.9% |
The emergency lender who wired SAR 3M under pressure now holds more of the company than either founder.
What the table shows
The company still operates. Revenue is real. The team is intact. The founders hold 16.5% combined, behind a stack that pays the recapitalisation investor 2x its money and then participates alongside common, with the earlier 1x preferences behind it. Whether the founders see anything at a given exit price depends on the seniority between those classes and on whether each preference participates. It is arithmetic by then, not negotiation.
What went wrong is not one decision. It is the compounding: no vesting on the split, a cap set for speed, a pool created pre-money at seed, a full ratchet accepted with emergency money, a second pool created pre-money at Series A, a recapitalisation signed with a participating preference on top.
Each decision was locally rational. Together they transferred the company.
Founders who understand these mechanics before the first round negotiate differently. They push back on ESOP timing. They model the table at Series B before signing at pre-seed. They read anti-dilution as a live term rather than boilerplate, because it is the clause most likely to be dormant for two years and decisive in the third.
Structure is not paperwork. It is the document that decides who owns the outcome.
Model inputs: pre-seed SAR 500k on post-money capped SAFEs at 15%; seed $2M for 20% at $10M post with a 10% pool sized on post-money and carved from pre-money; bridge SAR 3M at 20% discount with full ratchet, converting at Series A; Series A $6M at $20M pre-money, seed pro-rata of $1.5M taken inside the round, pool refresh of 5% of post-money; recapitalisation $4M at $3.2M pre-money with 2x participating preference. SAR converted at 3.75 to the dollar. Percentages are rounded to one decimal and each table sums to 100%.
