Founder and shareholder guide
Founders often talk about needing a “founder agreement”, but once a UK company has been incorporated and shares have been issued, the more important document is usually a shareholders’ agreement. The right document depends on what stage the business is at and what risks the founders need to control.
Quick answer
A founder agreement can be useful at the very early stage. For a UK limited company with issued shares, a shareholders’ agreement is usually the key ownership/governance document.
Many businesses use early founder terms first, then replace or supplement them with a shareholders’ agreement once the company structure is clear.
Terminology
In the UK, “founder agreement” is often an informal label. It can cover different things depending on the stage of the business, including pre-incorporation arrangements, collaboration terms, vesting expectations, IP ownership, role expectations and confidentiality.
It may be useful for very early discussions, but it is not a substitute for proper company constitutional documents once shares are issued. If founders become shareholders, the shareholders’ agreement usually becomes the core private document for ownership and governance.
Do not rely on a vague founder agreement once shares, voting rights and exits need to be controlled.
Document map
Articles of association are separate constitutional rules. Every limited company must have articles of association, and model articles are standard default articles a company can use. A shareholders’ agreement does not replace the articles, and the two should be consistent where they overlap.
Some arrangements may need to be reflected in the articles as well as the shareholders’ agreement, especially where share rights, transfer mechanics or company constitution issues overlap.
Early founder terms
Early founder terms are usually about expectations before the company structure is settled. They can reduce ambiguity, but they should not be left untouched once the business has incorporated and issued shares.
Founder roles and responsibilities
Time commitment
Initial contributions
Confidentiality
IP created before company formation
Decision-making before incorporation
Expenses and funding expectations
What happens if a founder walks away early
Whether a company will be incorporated
How shares may be allocated later
These points may still need to be replaced or formalised properly once the company is incorporated.
Shareholder rules
Once shares have been issued, the practical risks are usually ownership, control, transfers, exits, valuation, confidentiality and what happens if founders disagree or leave.
Share ownership and voting
Reserved matters
Director appointment rights
Share transfers and pre-emption rights
Good leaver / bad leaver provisions
Founder exits
Deadlock
Drag-along and tag-along rights
Dividends and funding
Confidentiality
Restrictive covenants, where appropriate
Valuation and buyout mechanics
Dispute resolution
Relationship with articles
Separate the roles
A founder may also be a shareholder, director, employee, consultant, or all of these. Each role has different rights and obligations, so ownership rights should not be confused with employment terms or director powers.
Commercial originator or early contributor. The title is practical rather than a single statutory company role.
Owns shares and has rights attached to those shares, such as voting or dividend rights depending on the share terms.
Manages the company and owes director duties. Board rights should not be confused with ownership rights.
Works under employment terms and has employment rights. Employment terms need their own contract or written particulars.
Provides services independently if the arrangement is genuinely self-employed and the contract reflects the real working relationship.
A shareholders’ agreement regulates shareholder relationships. An employment contract regulates employment terms. A freelance agreement regulates independent contractor services. Board or director rights may sit in articles, service agreements, board minutes or other company documents.
Founder exits
Founder exits are where vague early arrangements often break down. If a founder stops contributing, the company needs clear rules before resentment or valuation disputes take over.
a founder may leave but keep shares
the company may have no clear buyback or transfer process
there may be disputes over valuation
IP, client relationships and confidentiality can become disputed
good leaver / bad leaver provisions can matter, but need careful drafting
Bracton documents
Start with the shareholders’ agreement for ownership and governance. Add separate documents where confidentiality, employment or independent services need their own terms.
Primary document
Use this once founders or other parties hold shares and need rules for ownership, decisions, exits, transfers, deadlock and disputes.
Create a shareholders’ agreement →Confidentiality
Use an NDA when founders, investors, consultants or third parties are sharing sensitive business information before terms are finalised.
Create an NDA →Founder as employee
Use where a founder also works under employment terms and the company needs separate pay, role, hours, holiday, notice and IP provisions.
Create an employment contract →Founder or consultant services
Use where a founder, adviser or consultant separately provides genuinely independent services and the scope, fees, status and IP need written terms.
Create a freelance agreement →Common mistakes
thinking a founder agreement replaces a shareholders’ agreement
never updating early founder terms after incorporation
failing to assign or clarify IP
issuing shares without exit rules
ignoring 50:50 deadlock
failing to deal with founder departures
confusing director rights with shareholder rights
not aligning shareholder terms with articles
waiting until a dispute starts
copying startup documents from another jurisdiction without adapting them
Take advice for investor-backed startups, complex equity, tax-sensitive transfers, EMI/options, regulated matters, complex IP assignment, vesting or reverse vesting arrangements, or high-value disputes.
