Common Legal Mistakes Early-Stage Founders Make

Splitting equity verbally with no vesting

The single most common mistake is dividing equity verbally, with no written agreement and no vesting. Two founders agree to a 50/50 split, start working, and never document it. If one founder leaves after a few months, they technically still own half the company — and the remaining founder cannot recover the shares.

The fix is a founders agreement with vesting: equity is earned over time (commonly four years with a one-year cliff), and unvested shares return to the company if a founder leaves. This is far cheaper to put in place at the start than to negotiate during a departure.

Not assigning IP to the company

If the company does not own its intellectual property, it does not own its product. This mistake happens when code, designs or know-how are created before incorporation, or by contributors who never signed an assignment. The result is that an individual — not the company — owns rights the company depends on.

Every founder, employee and freelancer should sign an IP assignment agreement transferring all relevant rights to the company. This is simple to do and prevents a discovery during due diligence that can delay or kill a deal.

Signing documents without understanding them

Founders frequently sign documents — term sheets, SAFEs, convertible loans, customer contracts — without fully understanding the terms. The signature is binding regardless. A valuation cap, a discount, a liquidation preference, or a change-of-control clause can each have a large effect that is invisible until later.

The fix is simple: every document you sign should be reviewed and explained before signing. The cost of a review is a small fraction of the cost of a term you did not realize you agreed to.

Ignoring the cap table

The cap table is the map of who owns the company. Founders often maintain it informally — or not at all — until an investor asks for it. At that point, reconstructing the cap table from memory and scattered emails is slow, error-prone, and damaging to credibility.

Every share issuance, SAFE, convertible loan and option grant should be recorded as it happens, with the underlying documents. A clean cap table that matches the paperwork is a prerequisite for fundraising, not a byproduct of it.

The Cap Table Explained guide covers how to read and maintain one.

Using freelancers without written agreements

Startups rely on freelancers for design, development and marketing. Without a written agreement that includes IP assignment and confidentiality, the freelancer may retain rights to their work, and the company may not own the output it paid for.

A simple written agreement — covering scope, payment, IP assignment, confidentiality and the relationship's nature — protects both sides and prevents disputes later. It should be signed before the work begins, not after.

Relying on verbal investor commitments

A founder's word that they will invest is not an investment. Until a document is signed and the funds are transferred, the commitment is not binding. Founders who plan around verbal commitments — hiring, spending, or signing leases — can find themselves without the capital they expected.

The protection is to treat money as received only when it is in the bank account under a signed document, and to plan expenditures accordingly. A term sheet is a step toward an investment, not the investment itself.

Neglecting privacy and terms

If the company collects user data, operates a website or app, or sells to other businesses, it needs proper terms of service and a privacy policy. These are not optional formalities — they affect liability, compliance and trust, and they are reviewed during due diligence.

Using a copied template that does not match the company's actual practices can be worse than having no document, because it creates representations the company does not meet. The documents should reflect how the product actually works.

How to prevent all of the above

The pattern across all of these mistakes is the same: a legal step is deferred because it seems non-urgent, and it becomes expensive later. The prevention is to address the legal foundation early — incorporation, founders agreement, IP assignment, cap table, contracts and privacy — and to review every document before signing it.

If you are early-stage and unsure what to fix first, the Early-Stage Founder Legal Assessment identifies the gaps before they become problems. The cost of a short consultation is a fraction of the cost of any one of these mistakes.
