Co-founder Agreements for Media Agencies in Australia

A media agency can look simple at the start. Two or three founders know the industry, land a few clients, split the work and get moving. The trouble usually starts later, when one founder brings in most of the clients, another handles creative delivery, and nobody has properly agreed who owns the agency, how profits are shared, or what happens if someone leaves.

Common mistakes are easy to spot. Founders rely on verbal promises, assume a 50/50 split will stay fair forever, or forget to deal with client relationships, intellectual property and restraint clauses before they sign. Another big one is treating a co-founder agreement like a generic template, even though media agencies often have unusual assets such as brand strategy frameworks, ad account access, production files and key client goodwill.

This guide explains what a co-founder agreement for media agency businesses should cover in Australia, the legal issues to check before you sign, and the mistakes that most often create disputes once money, clients and staff are involved.

Overview

A co-founder agreement is the rulebook between the people building your media agency. It sets out who owns what, who makes decisions, what each founder is expected to contribute and what happens if the relationship changes.

For Australian media agencies, the agreement should deal with both standard founder issues and agency-specific risks, especially client ownership, creative work, platform access and confidential methods.

• Founder roles, responsibilities and decision-making authority
• Equity splits, vesting and what each founder contributes
• How salaries, dividends and profit distributions will work
• Who owns intellectual property, creative assets and agency systems
• Who controls client contracts, ad accounts and agency logins
• What happens if a founder stops performing, wants to exit or becomes uncontactable
• Restraint, non-solicitation and confidentiality terms
• Dispute resolution steps before the issue becomes destructive
• How the agreement works alongside your company constitution and shareholders agreement

What Co-founder Agreement for Media Agency Means For Australian Businesses

A co-founder agreement for media agency businesses is a practical contract that reduces uncertainty before the pressure hits. It is most useful when everyone still gets along, because that is the best time to set expectations clearly.

In plain English, it answers the questions founders usually avoid in the early stage. Who owns the business? Who decides on hiring or major spending? What if one founder does not deliver? Who keeps the clients if someone leaves? Without written terms, the business can become hard to manage very quickly.

Why media agencies need a tailored founder agreement

Media agencies often grow through relationships and intangible assets rather than stock or equipment. A founder may bring in a major client, hold access to advertising platforms, supervise freelancers, develop pitch decks or create repeatable campaign systems that become central to the agency.

That means a generic founder agreement can miss the real source of value. If the agreement does not say clearly that client work product, internal processes, account credentials and agency IP belong to the business, disputes can follow when a founder exits or starts a competing agency.

How it fits with your business structure

Most founder arrangements in Australia sit inside a company structure, but the exact documents you need depend on how the agency is set up. If you operate through a proprietary limited company, the co-founder agreement may overlap with a shareholders agreement, company constitution and any share issue documents.

If your media agency is still operating informally or through a partnership-style arrangement, that creates more risk. The founders may believe they have equal rights, but the legal position can be unclear if shares were never issued properly or the company records do not match what everyone thinks was agreed.

Before you sign, make sure the agreement lines up with:

• ASIC company records and the share register
• Any company constitution already adopted
• Existing employment or contractor agreements for founders
• Client service agreements and who is named as the supplier
• Intellectual property assignments for logos, content, designs and strategy materials

What founders usually want the agreement to do

Most media agency founders want three things from the document. They want clarity, fairness and a way out if things go wrong.

A well-drafted agreement usually covers:

• Ownership percentages and whether they change over time
• Whether shares vest gradually or are granted upfront
• Minimum work commitments and role descriptions
• Decision rules for major issues such as borrowing, hiring senior staff, issuing new shares or selling the business
• Payment arrangements, including salary versus profit share
• What happens if a founder leaves voluntarily, is removed or becomes unable to work
• Whether a departing founder can solicit clients, staff or suppliers
• How deadlocks and disputes are handled

The main point is simple. A co-founder agreement is not there because you expect a fight. It is there so the business can keep operating if the founders disagree, change direction or stop working well together.

Legal Issues To Check Before You Sign

Before you sign a co-founder agreement for media agency operations, check that it matches how the business actually works. The biggest legal problems come from documents that sound sensible in theory but do not reflect the agency’s real cash flow, roles or client relationships.

Equity split and vesting

An equal split is common, but it is not automatically fair. One founder may contribute cash, another may contribute client introductions, and another may be doing the day-to-day delivery full time.

Before you sign, be clear about:

• What each founder is contributing now
• What each founder is expected to contribute over the next 12 to 24 months
• Whether equity should vest over time instead of being fully owned on day one
• What happens to unvested shares if a founder leaves early

Vesting can be especially useful where the agency has not yet stabilised. It helps avoid the situation where a founder walks away after six months but keeps a large ownership stake while others keep building the business.

Roles, authority and decision-making

Founders often assume their titles tell everyone what they can decide. They usually do not. If one founder handles operations and another handles growth, you still need clear rules on what each person can approve without unanimous consent.

Set out which decisions can be made by one founder and which require all founders to agree. In a media agency, that often includes:

• Taking on large client commitments
• Discounting fees below a set threshold
• Hiring employees or long-term contractors
• Entering finance arrangements
• Purchasing production equipment or software subscriptions above a set amount
• Opening new service lines, such as influencer campaigns, video production or performance marketing

Intellectual property ownership

This is one of the most important areas for agencies. Your value may sit in campaign concepts, templates, reporting systems, creative files, strategy frameworks, internal know-how and the agency brand itself.

The agreement should make clear:

• That all agency IP created by founders for the business belongs to the company or agreed entity
• Whether any pre-existing IP is excluded and merely licensed to the business
• Who can use portfolio material and case studies after a founder leaves
• How domain names, social media handles, designs and presentation decks are controlled

If this point is vague, a departing founder may argue that key methods, files or creative systems are theirs personally. That can disrupt client work and lower the value of the agency.

Client relationships and account control

For many media agencies, the client list is the business. That is why the agreement should deal directly with ownership and control of client relationships.

Before you rely on a verbal promise, set out:

• Whether clients belong to the agency or to an individual founder relationship
• Who signs client contracts
• Who has access to ad manager accounts, analytics platforms and CRM systems
• What happens to those accounts if a founder exits
• Whether a departing founder can approach current or recent clients

These clauses need careful drafting. In Australia, restraint and non-solicitation provisions can be difficult to enforce if they are too broad, so they should be tailored to what is reasonably necessary to protect the business.

Pay, reimbursements and profit distributions

Many founders assume they can sort out money later. That often leads to resentment fast, especially where one founder needs regular income and another is willing to wait for future profit.

Your agreement should deal with:

• Whether founders are paid salaries, director fees or nothing initially
• How expenses are approved and reimbursed
• When profits can be distributed
• What financial information each founder can access
• Whether extra capital contributions are required if cash runs short

Tax treatment depends on the structure and payment method, so founders should also speak with an accountant or tax adviser before finalising these terms.

Exit rules and founder bad behaviour

The agreement should say what happens if a founder leaves, wants to sell, stops working or acts against the agency’s interests. This is where founders often get caught, because everyone focuses on the exciting parts and avoids the difficult scenarios.

Good exit clauses often cover:

• Notice periods for voluntary departure
• Share transfer rules and pre-emptive rights
• How shares will be valued
• Good leaver and bad leaver outcomes
• Removal for serious misconduct, fraud or repeated non-performance
• What happens on death, disability or long-term incapacity

Confidentiality, privacy and data handling

Media agencies regularly handle sensitive client information, campaign data and customer datasets. A founder agreement should support your broader privacy and confidentiality position, especially if founders can access personal information or confidential marketing plans.

Where relevant, make sure the agreement is consistent with:

• Any privacy obligations the business has under Australian law
• Confidentiality terms in client contracts
• Data access controls and password management
• Rules around using client data for samples, pitches or case studies

Dispute resolution and deadlock

Deadlock clauses matter most in agencies with two equal founders. If there is no agreed tie-break process, major decisions can stall and the business can freeze at exactly the wrong time.

Common options include internal escalation, mediation, expert determination for valuation issues, or a buy-sell mechanism. The right approach depends on the ownership structure and the level of trust between founders.

Common Mistakes With Co-founder Agreement for Media Agency

The most common mistake is waiting until after a problem appears. Once a founder has stopped pulling their weight, started speaking to clients privately or challenged ownership of the agency brand, it is much harder to get agreement on fair terms.

Using a generic template without agency-specific terms

Many templates deal with shares and decision-making but say little about creative assets, ad accounts or client transitions. That gap matters in media businesses because these are often the assets that keep revenue flowing.

If your agreement ignores those practical details, a dispute can become operational as well as legal. The business may lose access to platforms, files, passwords or client communications overnight.

Not documenting founder contributions properly

Founders often say they will all contribute equally, but they mean different things. One person may think equal means equal time. Another may think it means equal cash. Another may think it means equal responsibility for winning work.

Spell out the expectations. If someone is meant to work full time, bring a specific client pipeline or invest a set amount, say so clearly.

Confusing ownership with effort

A founder may work harder at one stage and still not be entitled to more equity unless the agreement says ownership can change. The reverse is also true. A founder with a large shareholding may not be doing enough to justify keeping all of it if vesting or performance-based milestones were never included.

This is why founders should agree early on whether equity is fixed, earned over time or linked to measurable milestones.

Ignoring restraints because everyone trusts each other

Trust is useful, but it is not a substitute for drafting. Media agencies are relationship-heavy businesses, and a departing founder may be able to move clients quickly if there are no confidentiality, non-solicitation or restraint provisions.

That said, overly broad restraints can be risky too. Clauses that try to block someone from working in the industry entirely, for long periods or across wide geographic areas may be harder to enforce. The best approach is targeted protection tied to real business interests.

Forgetting that client contracts and founder contracts must align

Your co-founder agreement cannot fix every issue if the client-facing documents tell a different story. For example, if a founder signs client contracts personally instead of in the company name, ownership of the relationship can become less clear.

Check that your service agreements, statements of work and platform authority documents support the structure set out in the founder agreement.

Leaving valuation too vague

Saying shares will be bought back at a fair value sounds sensible, but it often creates arguments. Fair to whom, and measured how?

It is better to set a valuation process, such as:

• Agreement between founders within a fixed period
• Valuation by an independent accountant or expert
• A formula tied to revenue, profit or another metric if appropriate
• A discounted outcome for bad leaver events if legally appropriate

Not updating the agreement as the agency grows

The agreement you need at two founders and three clients may not suit a larger agency with employees, contractors, retained clients and outside investors. Review the document when the business changes meaningfully.

Typical trigger points include:

• Issuing new shares
• Bringing in an investor
• Hiring senior leadership
• Acquiring another agency or book of clients
• Expanding into production, publishing or talent management

FAQs

Is a co-founder agreement legally binding in Australia?

Yes, if it is properly drafted as a contract and signed by the parties, it can be legally binding. Its enforceability still depends on the wording, the surrounding documents and whether specific clauses, such as restraints, are reasonable.

Do media agency founders also need a shareholders agreement?

Often, yes. If the business operates through a company, a shareholders agreement may be the better place for share-related rights and transfer rules, or it may work alongside a co-founder agreement. The key point is that the documents must be consistent.

Can we just agree to split everything 50/50?

You can, but equal ownership does not solve practical issues by itself. You still need terms covering roles, decision-making, exits, IP ownership, client control and deadlock.

Who owns the client relationships if one founder brought them in?

That depends on your contracts and the wording of the founder agreement. If you want the agency to own the client relationship rather than the individual founder, say so clearly and make sure client agreements are entered in the business name.

What if one founder wants to leave after six months?

The answer should be in the agreement. Good drafting deals with notice, transfer of shares, return of agency property, ongoing confidentiality obligations and whether any restraint or non-solicitation terms apply after exit.
