AI Vesting Agreement Generator for UK Businesses

If you need to lock in founder or employee equity properly, an ai equity vesting agreement generator uk businesses can actually use is a practical starting point. Vesting agreements set out how shares or options are earned over time, typically with a cliff period and a linear schedule thereafter. Get this wrong and you risk co-founders walking away with equity they haven't earned, or employees holding shares that create cap table headaches later. Atornee lets you describe your situation in plain English and generates a structured UK-compliant vesting agreement you can export to Word or PDF in minutes. It covers standard four-year vesting with a one-year cliff, good leaver and bad leaver provisions, and acceleration clauses where relevant. This is not a substitute for a solicitor on complex equity structures, but for early-stage founders and growing teams who need a solid first draft fast, it removes the blank-page problem entirely and keeps costs down while you're still finding your feet.

Why this matters

Most early-stage UK founders either skip vesting agreements entirely or copy a template from the internet that doesn't reflect UK company law or their actual situation. The result is ambiguity around what happens when a co-founder leaves early, no clear good leaver or bad leaver definitions, and provisions that don't align with Companies Act 2006 requirements. Hiring a solicitor to draft from scratch can cost £500 to £1,500 for a straightforward agreement. That's a real barrier when you're pre-revenue. The pain is real: equity disputes are one of the most common and damaging early-stage founder conflicts, and most of them stem from agreements that were never written down or were written badly.

The Atornee approach

Atornee isn't a template library. You describe your vesting structure in plain English — number of founders, share classes, cliff length, leaver provisions, acceleration triggers — and the AI drafts a document built around your specifics. It flags where your inputs create legal ambiguity, suggests standard UK market practice where you haven't decided yet, and produces a clean exportable document. You're not filling in a form with fixed fields. You're having a structured conversation that results in a draft you can take to a solicitor for review or use directly for straightforward arrangements. It's faster than a solicitor, cheaper than a template service, and more tailored than a generic download.

What you get

A UK-specific equity vesting agreement drafted around your actual share structure, cliff period, and leaver definitions — not a generic template
Good leaver and bad leaver provisions written in plain English with clear consequences for each scenario
Acceleration clause options for single-trigger and double-trigger events, with explanations of when each applies
Export to Word or PDF so you can share with co-founders, investors, or a solicitor for final review
Inline flagging of any inputs that create legal ambiguity or deviate from standard UK market practice

Before you sign checklist

1
1. Agree the total equity pool and each founder or employee's allocation before you start drafting
2
2. Decide on your vesting schedule — standard UK practice is four years with a one-year cliff, but document your reasoning if you deviate
3
3. Define what counts as a good leaver and bad leaver in your context before the AI drafts — this is the clause most likely to cause disputes
4
4. Confirm whether you want acceleration provisions and under what circumstances — change of control, termination without cause, or both
5
5. Check whether shares are already issued or whether this agreement covers options under an EMI or unapproved scheme, as the drafting differs
6
6. Export the draft and share it with all parties before signing — do not sign the same day you generate it
7
7. If your structure involves EMI options, a share buyback mechanism, or drag-along rights, escalate to a solicitor before finalising

FAQ

Is an AI-generated vesting agreement legally binding in the UK?

Yes, if it's properly executed. A vesting agreement is a contract, and UK contract law doesn't require a solicitor to draft it for it to be enforceable. What matters is that the terms are clear, both parties understand what they're signing, and the document is executed correctly. Where it gets complicated is if your structure involves EMI options or specific share class rights — those interact with tax law and Companies Act requirements in ways that benefit from professional review.

What's the standard vesting schedule for UK startups?

Four years with a one-year cliff is the most common structure. This means no equity vests in the first twelve months, then 25% vests at the cliff, and the remainder vests monthly or quarterly over the following three years. Some early-stage founders use shorter schedules, but investors typically expect to see a four-year structure as it aligns incentives properly. Atornee will flag if you input something that deviates significantly from market norms.

Do I need a solicitor to draft a vesting agreement for co-founders?

Not always. For a straightforward two-founder setup with standard vesting and clear leaver provisions, a well-drafted AI-generated agreement reviewed by both parties is a reasonable approach. You should involve a solicitor if you're raising investment and investors want to review the cap table, if you have more than two or three founders with different share classes, or if there are existing shareholders whose rights might be affected.

What's the difference between a vesting agreement and an EMI option agreement?

A vesting agreement typically governs shares that are already issued or will be issued directly. An EMI option agreement governs the right to buy shares in the future at a fixed price, with tax advantages under HMRC's Enterprise Management Incentive scheme. EMI agreements have specific HMRC requirements and need to be notified to HMRC within 92 days of grant. Atornee can help you draft a vesting agreement, but EMI option agreements should be reviewed by a solicitor or tax adviser given the HMRC compliance requirements.

Can I use this for employee equity, not just co-founders?

Yes. The generator works for both founder vesting and employee equity arrangements. For employees, you'll want to be clear about whether you're granting shares directly or options, and whether the arrangement is tied to their employment contract. Good leaver and bad leaver definitions become especially important for employees, as they interact with employment law around dismissal and resignation.

Does Atornee store my equity and company data?

Atornee handles your data in line with UK GDPR. You can review the privacy policy on the site for specifics. As a general principle, avoid inputting more personal or commercially sensitive information than the document actually requires — describe your structure accurately but don't paste in full cap tables or personal financial details unless the document needs them.
