There’s a moment in almost every early-stage financing when the conversation shifts from excitement to diligence. Investors who were enthusiastic about your business start asking for documents — and what you hand over either builds confidence or raises questions.
Most founders expect scrutiny of their financials. Fewer are prepared for how closely investors examine the internal agreements that govern the founding team. Gaps in those documents don’t just slow a deal down — they can affect how investors perceive risk and, in some cases, whether they proceed at all.
What Documents Do Investors Expect to See?
When investors conduct diligence on an early-stage company, they’re asking a simple question: is this company’s house in order? The core documents they look for include founder equity agreements with vesting schedules, IP assignment agreements, and foundational governance documents — a certificate of incorporation and bylaws corporation and a certificate of organization and a LLC agreement for an LLC. These need to exist, be properly executed, and tell a consistent story.
For a deeper look, this series also covers what corporation governance documents you need and how LLC governance documents work. In this article, we discuss some of the other key agreements.
Why Do Founder Equity Agreements Matter to Investors?
Founder equity agreements establish who owns what and on what terms. They sound basic, but the details matter enormously.
Investors want to see that equity was issued through a formal stock purchase agreement, that the shares were properly authorized and priced, and that the transaction was approved by the board.
Informal arrangements — a promise made over email, shares issued without documentation — create legal uncertainty that investors aren’t willing to accept. If ownership can’t be cleanly established, the deal slows down while lawyers work to resolve it.
The other thing investors look at closely is whether founder shares are subject to vesting. A founder who holds fully vested shares from day one carries a different risk profile than one whose ownership is tied to continued service. If a co-founder walks away six months after a round closes, investors want to know the company has some protection. Most institutional investors expect vesting schedules to be in place — and if they aren’t, they’ll often require them as a condition of the investment.
A special note on startup equity for consultants, part-time founders and academics. Be careful that they are subject to vesting, even more so than full-time founders. The stories of part-time founders walking away with a significant equity position after barely doing anything are too numerous to count.
What Is a Co-Founder Agreement and Why Does It Matter?
Beyond individual equity arrangements, investors want to understand how the founding team governs itself. A co-founder agreement or shareholder addresses questions like decision-making authority, what happens if a founder leaves, and whether there are restrictions on transferring shares. Investors are betting on the team as much as the business — and a founding team with no written understanding of how disputes get resolved, or what happens to a departing founder’s equity, is a risk they’ll flag. In an LLC, this is usually covered in the LLC Agreement.
How Can IP Assignment Issues Derail a Financing?
The question investors are asking is simple: does the company actually own the intellectual property that underlies the business? If founders or early employees developed key technology before the company was formed, or outside the scope of their employment, the IP may belong to them personally — or even worse, to a prior employer. Investors look for signed IP assignment agreements confirming everything has been transferred to the company. Missing assignments are a genuine deal risk and far easier to address before a financing than during one.
What Red Flags Do Investors Find Most Concerning?
Not all diligence issues are equal. Some create extra paperwork; others create real doubt. The issues that tend to concern investors most are those that suggest the founding team hasn’t been deliberate about how the company was built.
Undocumented equity arrangements top the list — any situation where someone believes they have an ownership stake that isn’t reflected in formal agreements. Inconsistencies between documents are also a red flag: a cap table that doesn’t match the equity agreements, or governance documents that haven’t been updated to reflect changes in the team or structure. And any unresolved disputes between founders — even informal ones — will surface in diligence and create concern about the team’s stability.
Beyond that, founders who take such issues lightly may also take other issues, such as safekeeping investor funds, less seriously than desired. Don’t start off poorly.
How to Get Ahead of These Issues Before You Raise
The goal isn’t perfect documentation before your first investor conversation — it’s making sure that when diligence begins, what investors find reflects reality clearly and completely. That means reviewing your founding documents before you’re in a process, not during one: equity arrangements papered, vesting in place, IP properly assigned, governance documents current.
Founders who move through diligence quickly are usually the ones who treated their internal agreements as seriously as their product. If you’re preparing for a raise and want to make sure your documentation is ready, we’re glad to help you work through it.
Frequently Asked Questions
What founder documents do investors review during diligence?
Investors typically look for founder stock purchase agreements with vesting schedules, IP assignment agreements, and the company’s core governance documents. They want to confirm that ownership is clearly documented, equity was properly issued, and the company owns its intellectual property.
Why do investors care whether founder shares are vested?
Vesting ties a founder’s ownership to continued service, which protects the company and its investors if a founder leaves early. A founder with fully vested shares and no ongoing commitment is a risk investors notice. Angel investors tend to care less about this, but most institutional investors expect vesting schedules to be in place and will often require them if they aren’t.
What is an IP assignment agreement and why does it matter?
An IP assignment agreement is a document confirming that intellectual property created by a founder or employee — code, designs, processes — has been formally transferred to the company. Without it, there’s a real question about whether the company actually owns its core assets. Investors will look for these, and missing assignments are one of the more serious diligence issues to resolve.
What happens if a co-founder’s equity was never formally documented?
Informal equity arrangements create legal uncertainty that investors aren’t willing to accept. If someone believes they have an ownership stake that isn’t reflected in signed agreements, that needs to be resolved — through proper documentation or a clear legal resolution — before a financing can close.
Can founder agreement issues kill a deal?
They can, though more often they slow it down and create leverage for investors to renegotiate terms or require cleanup as a closing condition. The issues most likely to threaten a deal are undocumented ownership, unresolved IP questions, and active disputes between founders. Most other documentation gaps can be remediated — but it’s far easier to do that work before a process begins.
