What founder protections should I negotiate in a term sheet?
By SuLe · Updated 1 July 2026
The founder protections worth negotiating are a founder-majority board, a tight list of reserved matters, fair leaver terms, sensible vesting with acceleration on a sale, and weighted voting on key resolutions where it matters. Control leaks through governance and consent rights far more than through your share percentage, so that is where to concentrate.
Key facts
- Keep a founder-majority board at seed — board composition drives control more than the cap table alone.
- Keep reserved matters tight and thresholds sensible, so investors do not gain a veto over routine decisions.
- Negotiate fair good-leaver/bad-leaver terms and a vesting schedule you can live with.
- Consider vesting acceleration on a sale so an exit does not strand your unvested shares.
- Weighted voting on specific resolutions is permitted in the UK (upheld in Bushell v Faith).
What protects my control of the company?
Control is mostly about governance, not percentage. Two levers dominate: the board and the reserved matters. Keep a founder-majority board at seed so investors have a voice but cannot outvote you, and keep the reserved-matters list tight so their veto covers only genuinely major decisions.
A minority investor with broad reserved matters and a board that can outvote you has more real control than their stake suggests. Founders who focus only on the equity split miss this.
Watch the drag-along threshold too: if it sits with investors, they could force a sale you oppose. Aligning these three — board, consent rights, drag — is the heart of protecting control.
How do I protect my equity if I leave or the company sells?
Two mechanisms matter: leaver terms and vesting acceleration. Good-leaver/bad-leaver provisions decide what happens to your shares if you leave, and fair definitions stop a routine departure being treated as bad faith.
Vesting acceleration decides what happens on a sale. Without it, a sale before your shares fully vest can leave value on the table. "Single-trigger" acceleration vests on the sale itself; "double-trigger" needs a sale plus, for example, you being let go afterwards.
Negotiate both explicitly. The founders-equity cluster covers leaver mechanics in depth; the point here is to raise them at the term-sheet stage, not leave them to the long-form drafting.
Is weighted voting allowed, and when is it useful?
Yes. UK law allows shares to carry extra votes on specific resolutions — a protection upheld by the House of Lords in Bushell v Faith. A founder's shares can be given weighted votes on, say, a resolution to remove them as a director.
It is a targeted tool, not a way to override investors on everything. Used narrowly, it can protect a founder against being removed by a bare majority; used too broadly, it will simply be rejected in negotiation.
Because it must be drafted into the articles precisely, weighted voting is a place to get proper advice. Applied to the wrong resolutions, it either fails to protect you or poisons the deal.
Where does UK law set the baseline?
Several protections have a statutory floor under the Companies Act 2006. Class rights cannot be varied without class consent; certain decisions need a special majority; and directors owe duties to the company that constrain even investor-appointed directors.
Weighted voting on removal resolutions works within this framework — the Act's default removal process can be modified by carefully drafted articles. UK venture terms commonly start from the BVCA model documents, which set a market-standard balance you negotiate around.
Knowing which protections are statutory and which are purely contractual tells you where you have leverage and where the law already has your back.
| Protection | What it guards | Founder ask |
|---|---|---|
| Founder-majority board | Day-to-day control | Keep founder majority at seed |
| Tight reserved matters | Freedom to operate | Limit to major items, sensible thresholds |
| Fair leaver terms | Your equity on departure | Reasonable good/bad-leaver definitions |
| Vesting acceleration | Equity on a sale | Single- or double-trigger acceleration |
| Weighted voting | Against removal | On key resolutions only (Bushell v Faith) |
Worked example
Kwame and Ines raise a £1.5m seed round for their fintech from a lead fund taking 22%. On the first draft the fund proposed a board it could tip with an independent, broad reserved matters, and a drag-along it controlled.
Working through the term sheet, the founders keep a two-to-one founder-majority board, trim reserved matters to share issues, borrowing above £150,000, disposals and winding up, and set the drag-along to need a share majority including at least one founder.
They also agree double-trigger acceleration on their vesting and weighted votes on any resolution to remove a founder-director. The headline valuation barely moved, but their control did.
Where founders go wrong
Negotiating valuation, ignoring governance
— board maths and reserved matters decide control; a great valuation with weak governance is a poor deal.Leaving leaver and vesting terms to "the long-form docs"
— raise them at the term-sheet stage while you still have leverage.Overreaching on weighted voting
— apply it narrowly to key resolutions, or investors will reject it outright.Missing the drag-along
— an investor-controlled drag can force a sale you oppose; tie it to a share majority that includes founders.

What founder protections should I negotiate?
The main ones are a founder-majority board at seed, a tight list of reserved matters, fair good-leaver/bad-leaver terms, sensible vesting with acceleration on a sale, and — where it matters — weighted voting on key resolutions. Together they protect your control and your equity.
Can founders keep control with a minority investor?
Largely, yes, if the governance is right: keep a founder-majority board, keep reserved matters tight, and watch drag-along thresholds. Control leaks through board composition and consent rights more than through the raw share percentage, so those are where to focus. [More: Should I give my investor a board seat?]
What is weighted voting and is it allowed in the UK?
Weighted voting gives certain shares extra votes on specific resolutions — for example, to resist removing a founder-director. UK law allows it: it was upheld in Bushell v Faith. It is a targeted protection, not a way to override investors on everything, and it needs careful drafting.
Should vesting accelerate if the company is sold?
Founders usually negotiate some acceleration so an exit does not leave unvested shares behind. "Single-trigger" accelerates on the sale itself; "double-trigger" needs a sale plus, for example, the founder being let go. What is fair depends on the deal, so it is worth negotiating explicitly.

Founder protections are won at the term-sheet stage and lost in the long-form drafting, where a tight reserved-matters list or a founder-friendly drag quietly disappears.
