How two co-founders split equity before it became a problem

Two co-founders were getting ready to launch a small software services business in the US. One founder planned to build the product full time. The other planned to handle sales, early customer relationships, and operations while keeping a part-time job for a few months.

They agreed the business had real potential, but they had not written down who owned what, what each person was expected to do, or what would happen if one person stopped working on the company. They were also considering forming an LLC, which is a limited liability company, a business structure that can separate business liabilities from the owners’ personal liabilities in many situations.

At first, the founders thought a simple 50/50 split would be enough. But once they started talking about future investors, decision-making, and workload, it became clear they needed more than a handshake. They needed a written founder agreement that matched how the business would actually run.

Their biggest concern was fairness. The full-time founder felt that equal ownership might not reflect the time and risk involved. The part-time founder worried about being pushed out later, even after helping land early customers.

They also had practical questions:

• Should ownership be earned over time instead of given all at once
• What happens if one founder leaves after three months
• Who can make spending decisions
• What if they disagree on bringing in a new partner or raising money
• Should confidential information and customer relationships be protected with an NDA, which is a non-disclosure agreement, and other contract terms

They had read advice online, but much of it conflicted or was too general. They wanted a licensed business attorney to explain the tradeoffs in plain language and draft something they could both understand.

For many owners, this is the point where a clear co-founder agreement matters. You can read more about that here: Partnership and founder agreements.

The founders used FoundryCounsel to get matched with a licensed business attorney. Matching was free for them. FoundryCounsel is not a law firm and does not provide legal advice. The founders chose whether to hire the attorney, and they paid the attorney directly through a flat fee for the legal work.

The attorney first asked for basic contact information and a short description of the issue. The founders did not need to send sensitive personal or business data through a form. Then the attorney walked them through the main choices.

Together, they worked on a written co-founder agreement that covered:

• The initial equity split
• A vesting schedule, meaning ownership would be earned over time instead of fully owned on day one
• A cliff, meaning a minimum period of service before any vested ownership would be earned
• Roles and decision-making authority
• What happens if a founder leaves, stops contributing, or wants to sell their interest
• Rules for intellectual property created for the company
• Basic confidentiality and non-solicitation terms

The attorney also explained how the agreement should fit with the company’s formation documents. For an LLC, that can include an operating agreement, which is the internal document that sets rules for ownership, management, and important business decisions, and articles of organization, which are the formation papers filed with the state to create the LLC. The founders were also told to confirm filing rules with the relevant Secretary of State and tax details with IRS.gov, including whether they needed an EIN, which is an Employer Identification Number issued by the IRS for tax and business filing purposes.

The final result was not just a number on a page. The founders left with a clearer working relationship.

Instead of arguing over whether 50/50 was "right," they had a structure that reflected timing, responsibility, and risk. A vesting plan reduced the chance that one founder would walk away early with a large ownership stake that no longer matched their contribution. Clear voting and approval rules also made everyday decisions easier.

Just as important, they had a process for hard conversations before outside money entered the picture. They did not get a guarantee of future investment, and no lawyer can promise that. But they were in a better position to speak with potential investors because their ownership and governance terms were organized and documented.

The main lesson was simple: early founder conversations are easier when everyone is still getting along. Waiting can make a solvable business issue feel personal.

The founders also learned that online templates are often too broad for real situations. A licensed attorney can help translate general ideas into documents that fit the company’s actual structure, state, and goals. Legal fees vary by state and scope, and any range you see online is not a quote. If you want a general overview, see How much does a business lawyer cost.

If you are setting up a business with another person, it may help to discuss:

1. Who is contributing cash, time, customers, or intellectual property
2. Whether ownership should vest over time
3. Who makes which decisions day to day
4. What happens if someone leaves or stops contributing
5. Which documents need to match your state filings and tax setup
