Founder and Shareholder Agreements for New Zealand Product Design Studios

If you are building a product design studio with a co-founder, the hard conversations usually get delayed until there is already money, stress, and client pressure involved. That is when small assumptions turn into big disputes. One founder thinks all IP belongs to the company, another assumes equal pay can wait, and nobody has written down what happens if one person leaves after six months.

For New Zealand product design studios, those gaps can become expensive quickly. You may be handling client retainers, developing original design systems, outsourcing prototypes, and pitching for long-term commercial work before your internal deal is properly settled. Common mistakes include relying on a handshake, splitting shares equally without matching roles and risk, and forgetting to deal with decision-making deadlocks.

A well-drafted founder shareholder agreement for product design studio businesses answers those issues early. It sets the commercial rules between founders, protects the studio's work product, and gives you a plan for exits, disputes, and future growth before you sign major client contracts or bring in investors.

Overview

A founder and shareholder agreement records how the owners of your product design studio will work together, make decisions, contribute value, and leave if things change. For a New Zealand studio, it is often the document that prevents ownership confusion around shares, design IP, client relationships, and founder exits.

The agreement should match the reality of your studio, not a generic template. If one founder leads industrial design, another handles brand strategy, and a third funds early prototyping, your document should reflect those different contributions clearly.

• Who owns shares, and whether ownership vests over time
• What each founder is expected to contribute, including time, cash, equipment, contacts, or specialist expertise
• Who owns existing and future intellectual property, including design files, prototypes, CAD work, processes, and branding created for the studio
• How directors and shareholders make decisions, and which matters require unanimous approval
• How founder salaries, drawings, dividends, and reimbursements are handled
• What happens if a founder wants to leave, becomes inactive, or breaches the agreement
• How shares can be sold, transferred, or bought back
• How confidential information and client relationships must be protected
• How disputes are managed before they damage the business

Why UK Businesses Use Shareholders’ Agreements

Despite the heading, the same practical reasons apply in New Zealand. Businesses use shareholders' agreements because the Companies Act rules and a company constitution usually do not deal with founder-specific expectations in enough detail.

For a product design studio, the main value is clarity. Before you sign a major client contract, hire staff, or spend money on prototyping tools, founders need to know who controls the business and what happens if plans change.

They separate ownership from friendship

Many studios are formed by friends, former colleagues, or collaborators who have already worked together on projects. That history can create confidence, but it can also hide different assumptions.

One founder may expect equal say in every design and commercial decision. Another may think the person bringing in clients should control pricing and strategy. A shareholder agreement puts those assumptions in writing before they become personal.

They deal with uneven founder contributions

Equal shares are common, but they are not always fair. One founder may contribute cash, another may work full time from day one, and another may bring a valuable book of business or proprietary design methods.

Your agreement can record:

• whether shares are issued immediately or vest over time
• whether founder loans will be repaid before profits are distributed
• whether unpaid work in the early stages is recognised in some other way
• what happens if a founder stops contributing at the expected level

This matters in studios where output depends heavily on individual skill and reputation.

They protect design intellectual property

Product design studios often create value long before cash flow catches up. That value may sit in concept sketches, CAD files, materials research, manufacturing know-how, testing methods, workshop processes, visual identities, or product systems.

If your internal paperwork is unclear, founders can later argue about whether that IP belongs to the individual creator or the company. A founder shareholder agreement should work alongside IP assignment wording so the studio owns what it needs to trade, license, and sell its services confidently.

They set rules for difficult founder moments

The document is most useful when something goes wrong. If a founder resigns, gets poached by a client, stops replying, or wants to sell shares to someone else, the agreement gives you a process.

That can include:

• notice periods and handover duties
• good leaver and bad leaver outcomes
• valuation methods for shares
• pre-emptive rights, so existing owners get first option to buy shares
• restraints aimed at protecting clients, staff, and confidential information

Without those written terms, exits often become messy and expensive.

They help studios grow without constant renegotiation

A young studio may begin with two founders sharing laptops and workshop space. A year later, it may have contractor designers, recurring commercial clients, and outside investors asking questions.

A good agreement gives you rules that still work as the business grows. It can cover new share issues, investor approval rights, dividend policy, and the difference between director powers and shareholder powers. That reduces friction when opportunities arrive quickly.

Legal Issues To Check Before You Sign

Before you sign, make sure the agreement reflects how your studio actually operates, not how you hope it will operate one day. The legal details that matter most are the ones tied to founder contribution, IP ownership, control, and exits.

Shares, classes, and vesting

Your first check is ownership mechanics. The agreement should match the company share register, any constitution, and the terms on which shares were issued.

If founder shares are meant to vest over time, that needs to be drafted properly. Otherwise, a founder who leaves early may keep a full equity stake despite contributing only a fraction of the expected work. Vesting clauses usually deal with timing, milestones, acceleration events, and what happens on departure.

If you plan to issue different classes of shares later, for example to investors or key staff, the agreement should not accidentally block that path.

Founder roles and decision-making authority

Studios often blur creative and commercial roles. That works until there is a disagreement about pricing, subcontracting, entering a commercial lease, or taking on a risky client.

Your agreement should say who can decide everyday matters and which issues need shareholder approval. Reserved matters often include:

• taking on debt above an agreed threshold
• issuing new shares
• changing the nature of the business
• signing major client contracts
• buying high-value equipment
• hiring senior staff
• entering or ending a lease
• selling key intellectual property

This is especially useful before you sign a manufacturing collaboration, workshop lease, or long-term development contract.

Intellectual property ownership and moral rights

For a product design studio, this is often the most valuable section. Founders may bring pre-existing design methods, libraries, templates, or concepts into the business. They may also create new work during the life of the studio.

The agreement should separate:

• IP a founder owned before joining the company
• IP licensed to the company for use
• IP assigned outright to the company
• new IP created for the company after formation

If founders work through personal devices, side entities, or contractor arrangements, the contract drafting needs extra care. Otherwise, the studio may promise ownership to clients without actually owning all underlying rights itself.

Confidential information and client relationships

Design studios hold more than just visual work. They often hold client briefs, prototype specifications, testing feedback, supplier quotes, pricing models, and unpublished concepts.

Your agreement should define confidential information clearly and say how it must be handled during and after a founder's involvement. It should also cover whether a departing founder can approach existing clients, suppliers, or staff. In New Zealand, restraint provisions need to be reasonable to be more likely enforceable, so broad one-size-fits-all wording can create problems.

Founder pay, loans, and expenses

Many founder disputes are really payment disputes. One person has been paying software subscriptions, another has taken low drawings, and another expects to be repaid for workshop equipment.

The agreement should line up with the practical money issues, including:

• whether founders receive salary, contractor fees, or nothing initially
• how reimbursable expenses are approved
• whether founder loans attract interest
• when loans are repaid
• whether dividends can be paid only after agreed conditions are met

You may also need separate service agreements if founders work in executive or design delivery roles.

Exit pathways and forced transfers

The real test of a founder shareholder agreement for product design studio businesses is what happens when a founder leaves under pressure. The document should deal with voluntary resignation, long-term illness, misconduct, insolvency, and sustained failure to contribute.

Key questions include:

• does the departing founder have to offer shares first to the others
• how is the share price calculated
• can the company buy back shares if the law and company documents allow it
• what happens to unvested shares
• what information and materials must be returned
• how quickly must design files, passwords, and client records be handed over

For a studio, access to files and systems can be just as important as the equity terms.

Dispute resolution

Founders rarely plan for deadlock, but deadlock is common where two founders hold equal shares. If one wants to move into manufacturing services and the other wants to stay advisory only, you need a process.

Your agreement can require staged dispute resolution, such as:

1. internal meeting between founders
2. written notice of the issue
3. mediation with an agreed mediator
4. a buy-sell or other deadlock mechanism if the issue cannot be resolved

This gives the business a path forward instead of months of paralysis.

Common Shareholders’ Agreement Mistakes

The most common mistake is treating the agreement like a formality after the real deal has already been made. When the legal document comes last, founders usually miss the issues that matter most to their studio.

Using a generic template that ignores the studio's work

A standard shareholders' agreement may cover share transfers and voting, but it often says very little about design files, prototype ownership, founder-created methods, or contractor IP chains.

If your studio develops product concepts, physical prototypes, packaging systems, or digital interface assets, your agreement needs to reflect that. This is where founders often get caught, especially when pitching enterprise clients who expect clear IP ownership.

Leaving pre-existing IP unclear

A founder may bring a material library, a design toolkit, or a process developed in a previous role. Another may bring a personal brand or portfolio methodology. If the agreement does not say whether those assets are licensed or assigned, arguments can surface later when the business wins bigger work.

This issue gets sharper when a founder exits and wants to keep using similar methods elsewhere.

Assuming equal shares mean equal effort forever

An equal split can work, but only if the expectations are genuinely equal. Problems start when one founder is full time and another treats the studio as a side project.

Vesting, minimum contribution requirements, or clearly stated role commitments can reduce that risk. Without them, resentment builds fast.

Forgetting director duties and company documents

A shareholders' agreement does not replace the Companies Act, director duties, or the company constitution. The documents need to fit together.

If your agreement says one thing and your constitution or share records say another, the inconsistency can create real uncertainty. Founders should also remember that directors still owe duties to the company, even when there is a private agreement between shareholders.

Writing restraints that are too broad

Founders often want strong protections if someone leaves with client knowledge and design know-how. That goal is understandable, but broad restraints that try to stop someone working anywhere in the industry for too long may be hard to rely on.

A more practical approach is to target the real risk, such as client solicitation, misuse of confidential information, and poaching key staff.

Ignoring future fundraising or key hires

Studios that plan to grow often need flexibility to issue shares, create option pools, or bring in strategic advisers. Agreements that are too rigid can create delays at the exact time the business needs to move quickly.

Before you sign, think about whether the document can still work if:

• an investor wants preference shares or reserved rights
• a senior designer is offered equity
• one founder wants to reduce hours but stay on the register
• the studio expands into manufacturing oversight or licensing work

Failing to update the agreement after change

Even a good agreement goes stale. New shareholders come in, founders change roles, service offerings shift, and old side letters keep circulating.

Review the agreement whenever there is a major business change. A stale document can be almost as risky as having none at all.

FAQs

Do New Zealand product design studios need both a constitution and a shareholder agreement?

Not always, but many studios benefit from having both. A constitution helps with company rules at a corporate level, while a shareholder agreement is usually better for founder-specific commercial arrangements such as vesting, exits, restraints, and confidential information.

Can a founder keep the IP they created before the studio was formed?

Yes, if the documents say so. The agreement should state whether pre-existing IP stays with the founder, is licensed to the company, or is transferred to the company, and on what terms.

What happens if one founder stops working but keeps their shares?

That depends on the agreement. Well-drafted terms can require share transfers, trigger buyback or pre-emptive processes, or apply vesting rules so an inactive founder does not keep more equity than intended.

Should founder salaries be included in the shareholder agreement?

The agreement can set the framework, but detailed pay and service terms are often better handled in separate employment or contractor agreements. The key point is making sure all documents match.

Can a shareholder agreement stop a founder from taking clients after they leave?

It can include non-solicitation and confidentiality terms aimed at protecting the business. In New Zealand, those restrictions should be reasonable and tailored to the real commercial risk.
