The Founder's Guide to the Share Subscription Agreement

What Is a Share Subscription Agreement (SSA)?

A Share Subscription Agreement (SSA) is the binding contract that turns an investor’s verbal “yes” into cash in your company’s bank account. It’s a legal agreement where an investor commits to buy a specific number of shares at a fixed price, and the company commits to sell them. Think of it as the purchase order for your startup’s equity.

This document is critical in your early fundraising efforts, especially for pre-seed and seed rounds involving angels or friends and family. It formalizes the investment, creating a clear legal record of who owns what.

SSA vs. Other Fundraising Documents

Founders are often drowning in legal documents. It’s easy to confuse them, but they have distinct purposes. Getting this wrong can kill deals and create legal messes.

Term Sheet: This is a non-binding outline of the deal's key terms (valuation, investment amount, etc.). It’s the engagement, not the marriage. You agree on the Term Sheet first, then draft the SSA and other legal docs to match it. · Share Subscription Agreement (SSA): This is the binding contract to execute the purchase outlined in the Term Sheet. If the Term Sheet is the plan, the SSA is the action. · Shareholders' Agreement (SHA): This is the long-term “operating manual” for all shareholders. It defines rules about voting, board seats, what happens if a founder leaves, and how shares can be sold in the future. New investors sign the SSA to buy their shares, and in doing so, often agree to be bound by the existing SHA. · Share Purchase Agreement (SPA): This is used when an investor buys shares from an existing shareholder (like a founder or early employee), not from the company itself. This is a “secondary” sale, and the money goes to the seller, not into the company’s treasury. The SSA is for “primary” issuance only.

Key Clauses in an SSA & What They Mean for You

Your lawyer will draft the full document, but you need to understand the key business and legal points you're committing to. Reading a 20-page legal document for the first time can be intimidating. Here’s what to focus on.

1. The Subscription & Issuance

This is the heart of the agreement. It will state in plain terms:

Investor: The legal name of the person or fund investing. · Number of Shares: The exact number being purchased (e.g., “100,000 shares”). · Class of Shares: Usually “Series Seed Preferred Stock” or similar. · Price Per Share: The price you agreed on (e.g., “$2.50 per share”). · Aggregate Purchase Price: The total check size (e.g., “$250,000.00”).

Founder Action: Double-check these numbers. A typo here can be a nightmare to fix later.

2. Conditions Precedent (CPs)

This section is a checklist of things that must be completed before the deal can close and the investor is obligated to wire the money.

Founders have signed their agreements. · The board has approved the transaction. · An updated cap table has been prepared. · The investor has signed the Shareholders' Agreement.

Founder Mistake Spotlight: Overly complicated CPs can kill momentum and delay closing for weeks. Avoid conditions that are outside your direct control or depend on a third party who isn't motivated. The goal is to get the cash in the bank, not create legal hurdles.

Your Goal: Keep the CP list as short and simple as possible. An investor should be able to wire funds the same day they sign the SSA.

3. Representations & Warranties (R&W)

These are statements of fact that both the company and the investor make to each other. If these statements turn out to be false, it can lead to legal claims.

The company is properly incorporated and in good standing. · The company has the authority to issue the shares. · The issued shares are valid and free of claims (“free and clear title”). · There are no undisclosed lawsuits or major liabilities.

They have the authority to make the investment. · They understand the risks of a speculative startup investment. · Crucially, that they are an “accredited investor.”

Founder Mistake Spotlight: Agreeing to overly broad company reps. For example, a rep saying “the company has not infringed on any intellectual property” is dangerous. A better version is “to the company’s knowledge, it has not infringed...”. This protects you from unknown risks. Push back against any rep that asks you to guarantee the future.

SEC Compliance: The Elephant in the Room (Reg D)

You cannot simply sell shares to anyone who will buy them. In the US, all offers and sales of securities must be registered with the Securities and Exchange Commission (SEC) or qualify for an exemption. Registering is a multi-million dollar process designed for IPOs. Startups rely on exemptions, primarily Regulation D (Reg D).

Rule 506(b): The Default for Startups

This is the “safe harbor” 99% of startups use. Here are the rules:

No General Solicitation: You cannot advertise your fundraising publicly. No tweets, LinkedIn posts, or public blog posts saying “We’re raising a seed round!” You must only approach investors with whom you have a pre-existing relationship or who are introduced through your network. · Unlimited Accredited Investors: You can raise from any number of accredited investors (individuals with >$1M net worth or >$200k/yr income). · Up to 35 Non-Accredited Investors: You can technically raise from a small number of non-accredited investors. Do not do this. The legal disclosure requirements are incredibly burdensome, and it will be a major red flag for all future investors and acquirers. Stick to accredited investors only.

Rule 506(c): The Public Raise

This rule lets you do what 506(b) forbids: general solicitation. You can publicly advertise your round. However, there’s a big catch:

You can ONLY accept funds from accredited investors. · You have a much higher legal burden to verify their accredited status. This means collecting bank statements, tax returns, or getting letters from their lawyers/accountants. A simple self-declaration form is not enough.

For most founders, the privacy and simplicity of 506(b) are far superior. Don't risk public fundraising unless you have a clear legal strategy for investor verification.

How to Apply This This Week

Find a Startup Lawyer: Don't use your uncle the real estate attorney. Ask other funded founders in your city for introductions to lawyers who specialize in early-stage venture deals. This is the single most important step. · Prepare an Investor Questionnaire: Ask your lawyer for a simple form that new investors can fill out. It should collect their legal name, address for notices, and have them formally check a box to confirm their accredited investor status. This is your key compliance document. · Review Your Lawyer's Template SSA: Get a copy of your law firm's standard SSA. Read it. Even if you don't understand every word, you'll be more prepared when a real deal is on the table. · Set Up a Basic Data Room: Create a folder with your certificate of incorporation, bylaws, and cap table. When an investor is ready to sign an SSA, they (or their lawyers) will ask for these as part of their diligence. Having them ready shows you’re a professional operator.
