Your offer letter is a contract — read it like one.

I've reviewed hundreds of startup offer letters. The pattern is grim: a template downloaded in 2019, customised once, sent without legal review, signed by founders and employees who didn't read past the salary line. Then someone leaves, or sues, or refuses to return a laptop, and a $1,500 lawyer review that wasn't done in year one becomes a $40,000 settlement in year three.

Your offer letter is not paperwork. It's the legal foundation of every employment relationship in your company. Here's what it should actually contain, in plain language.

The 10 sections every offer letter must address

• Role title and reporting line — specific, not 'as assigned by the company.'
• Start date and location — including remote-work rules and tax implications.
• Compensation — base, bonus, equity grant, vesting schedule (4yr/1yr cliff is standard).
• Benefits — what's included, what's not, when they kick in.
• Employment status — at-will (US), notice periods (UK/EU), probation rules.
• IP assignment — anything they invent during employment belongs to the company.
• Confidentiality and non-disclosure — define what's confidential, for how long.
• Non-compete or non-solicit — enforceability varies wildly by jurisdiction. Get local advice.
• Termination terms — notice, severance, what triggers 'for cause.'
• Governing law and dispute resolution — which court, which state, arbitration or not.

The clauses founders most often get wrong

Equity vesting

Specify the vesting schedule explicitly: 'X options vesting over 4 years, with 25% vesting on the first anniversary and the remainder vesting in equal monthly instalments.' Define what happens on termination (typically: 90-day exercise window unless extended), on a change of control (single or double trigger acceleration), and on death/disability. 'Standard vesting' is not a clause — it's a lawsuit.

IP assignment

Many template clauses are too broad to be enforceable (you can't own things they invented before they joined, or on personal time unrelated to your business). Use a 'prior inventions schedule' as an attachment where the employee lists pre-existing IP. This protects them and you.

Non-compete

Increasingly unenforceable. The FTC's 2024 rule banned most non-competes in the US (still under legal challenge). California, Minnesota, and most of the EU void them entirely. A non-solicit (no poaching of clients/employees for 12 months) is usually enforceable and often more useful.

The psychology: contracts as trust signals

Behavioural research from Stanford's Margaret Neale shows that the negotiation experience around an offer letter is one of the strongest predictors of first-year engagement. A clear, fair, well-explained offer letter signals 'this company is competent and respects me.' A sloppy template signals the opposite — and the candidate carries that signal into their first 1:1, their first deadline, and their first conflict. The offer letter is your first culture broadcast. Most founders treat it like a formality.

The 4-step founder fix

• Pay a local employment lawyer $800–$2,000 once to review and rewrite your template. This is the highest-ROI legal spend of your first three years.
• Maintain three templates: full-time, contractor, advisor. Don't blur them.
• Build a personalisation checklist. Every offer should have role title, start date, comp, equity, and reporting line filled in — never sent with template placeholders intact.
• Re-review the template annually. Employment law moves. The clauses that were enforceable in 2022 may not be in 2026.

When to walk a candidate through it (and when not to)

Always offer a 15-minute call to walk through the offer. Most candidates will decline. The ones who accept are the candidates who care about the details — exactly the people you want. Use the call to explain equity in plain language, walk through the vesting calendar, and answer questions about benefits. This single behaviour will set you apart from 90% of competing offers.

Take this home — the offer-letter audit

• Pull your current offer letter. Check it against the 10-section list.
• Find the last offer you sent. Was anything left as a template placeholder? Send a correction now.
• Book a 1-hour call with an employment lawyer in your primary jurisdiction. Bring your template.
• Add a 15-minute 'offer walkthrough' to your hiring process for every senior role.
• Calendar an annual offer-letter review. It's a 30-minute task that prevents 30-day problems.
