Launching a startup with co-founders is one of the most exciting decisions an entrepreneur can make. It is also one of the riskiest. Disputes between founders are among the leading causes of early-stage business failure, and most of those disputes trace back to a single, avoidable mistake: the absence of a clear, legally enforceable founder agreement. Our New York City founder agreement attorneys help entrepreneurs build their companies on a solid legal foundation, drafting agreements that define ownership, responsibilities, intellectual property rights, and exit terms before conflicts ever arise.
A founder agreement (sometimes called a co-founder agreement or founders' agreement) is a binding contract among the individuals starting a business. It establishes the essential terms of the founders' relationship with each other and with the company itself. While every agreement should be tailored to the specific venture, a well-drafted founder agreement typically addresses:
New York City is one of the most dynamic startup ecosystems in the world, spanning fintech, media, real estate technology, healthcare, fashion, and beyond. With that opportunity comes intense pressure to move quickly — and founders often defer formal agreements in favor of handshake understandings. Under New York law, that informality can have serious consequences.
Without a written agreement, founders may inadvertently create a general partnership under the New York Partnership Law, exposing each founder to personal liability for the obligations of the business and to default rules — such as equal profit sharing — that may not reflect the founders' actual intentions. If the founders form a corporation or limited liability company without addressing their internal relationship, New York's default statutory rules under the Business Corporation Law or the Limited Liability Company Law will fill the gaps, often in ways the founders never anticipated.
Notably, New York does not require an LLC to have a written operating agreement filed with the state, and many founders mistakenly assume the articles of organization alone protect them. They do not. A comprehensive founder agreement — often working in tandem with an operating agreement or shareholders' agreement — is the only reliable way to control your company's internal governance.
An equal equity split is not always a fair one. Founders contribute different things — capital, technical expertise, industry relationships, full-time commitment versus part-time involvement. We help founders have the difficult but essential conversation about equity allocation early, and we document the result clearly.
Just as important is vesting. A standard structure provides that founder equity vests over four years with a one-year cliff, meaning a founder who departs in the first year forfeits unvested shares. Vesting protects the company and the remaining founders from the all-too-common scenario in which a co-founder walks away after a few months but retains a large ownership stake indefinitely. We also counsel founders on the tax implications of restricted equity, including the critical 83(b) election, which generally must be filed within 30 days of the equity grant.
For technology and media startups in New York City, intellectual property is often the company's most valuable asset. If a founder develops code, designs, content, or inventions before or outside the formal scope of the company, ownership can be ambiguous — and that ambiguity can derail financing rounds or acquisitions. Our agreements include robust IP assignment provisions ensuring that all relevant work product, whether created before or after formation, is irrevocably assigned to the company. We also address potential conflicts arising from a founder's prior or concurrent employment, a frequent issue given how many New York founders launch ventures while still employed elsewhere.
Two founders with 50/50 ownership and no tie-breaking mechanism is a recipe for paralysis. New York courts can order dissolution of a deadlocked corporation in certain circumstances, but judicial dissolution is an expensive, unpredictable last resort. We build deadlock-breaking mechanisms into founder agreements — including buy-sell provisions, escalation procedures, and designated tie-breaker structures — so that disagreements do not destroy the business.
Founders leave. They take other jobs, experience health events, lose interest, or are asked to step aside. A founder agreement should anticipate each scenario and specify whether the company or remaining founders may repurchase the departing founder's equity, at what price, and on what timeline. Distinguishing between "good leaver" and "bad leaver" departures — for example, resignation versus termination for cause — allows the agreement to treat each situation appropriately.
New York courts will enforce confidentiality and non-solicitation provisions, and will enforce non-competition covenants only when they are reasonable in time and geographic scope, necessary to protect legitimate business interests, not unduly burdensome on the individual, and not harmful to the public. The enforceability landscape for non-competes in New York continues to evolve, and overly broad provisions risk being struck down entirely. We draft restrictive covenants designed to survive judicial scrutiny while genuinely protecting the company's trade secrets, customer relationships, and competitive position.
The founder agreement does not exist in isolation. Its terms must align with the company's organizational documents:
Our attorneys advise on entity selection and ensure that the founder agreement, governing documents, and equity instruments work together as a coherent whole — a detail sophisticated investors will examine closely during due diligence.
The best time is before the company generates revenue, raises capital, or builds significant intellectual property — ideally at or shortly after formation, when goodwill among the founders is at its peak and negotiating positions are balanced. That said, it is never too late. We regularly help existing New York businesses formalize founder relationships, restructure equity, and resolve ambiguities before they harden into disputes. If your company is preparing for a seed round or institutional financing, cleaning up founder documentation beforehand is essential.
We provide practical, business-minded counsel at every stage:
Templates rarely account for New York-specific statutory defaults, enforceability standards for restrictive covenants, or the particulars of your equity and IP situation. A flawed agreement can be worse than none at all, because it creates false confidence while leaving critical gaps.
When founders' interests materially diverge — for instance, in unequal equity negotiations — separate representation may be appropriate. We will advise you candidly about potential conflicts and the scope of our representation.
Costs vary with complexity, but they are modest compared to the expense of litigating a founder dispute or unwinding an ambiguous equity arrangement during due diligence. Many engagements are available on a flat-fee basis.
