How to Draft a Founder Vesting Schedule and Repurchase Agreement for a Delaware C-Corp Startup

Founder vesting for a Delaware C‑Corp is typically structured as a 4‑year schedule with a 1‑year cliff, documented in a restricted stock purchase (or repurchase) agreement. This protects the company if a founder leaves early and is a near-universal expectation for VC-backed startups. This article explains how to draft the vesting schedule and a founder repurchase agreement, key Delaware law and tax points (including 83(b)), and practical negotiation tips.

Why founder vesting matters in a Delaware C‑Corp

Founder vesting is a risk-management tool: it aligns incentives, reduces “dead equity,” and gives the company a contractual right to recover unearned founder shares if a founder stops providing services. For Delaware C‑Corps, vesting is most commonly implemented through restricted stock (shares issued up front but subject to the company’s repurchase option) rather than options. Investors also expect vesting as a baseline governance and cap-table hygiene measure.

In practice, “vesting” is not the company taking shares back automatically. It is the company having an option to repurchase some or all of the founder’s unvested shares at a specified price if the founder’s service ends. That option must be clearly drafted, properly approved, and consistent with the corporation’s charter, bylaws, and equity plan (if any).

Common founder vesting terms (market baseline)

While every company is different, a Delaware startup raising institutional capital will usually see some version of these terms:

1) Vesting schedule: 4 years with a 1‑year cliff

Typical schedule: 48 months total; 25% vests after 12 months of continuous service (the “cliff”), then the remainder vests monthly (or quarterly) over the next 36 months.

Example: Founder receives 4,000,000 shares of common stock. After 12 months, 1,000,000 are vested. Then 83,333 shares vest each month for 36 months (3,000,000 ÷ 36) until fully vested at month 48.

2) Commencement date and credit for prior work

Founders often start work before incorporation. The vesting “start date” can be the incorporation date, the date services began, or another negotiated date. If you choose a date before issuance, confirm the document mechanics still work (for example, the repurchase option period and IP assignment obligations) and that the board approvals reflect the agreed terms.

3) Acceleration (single-trigger vs. double-trigger)

Acceleration determines whether unvested shares vest early upon certain events:

Single-trigger acceleration: vesting accelerates upon a change of control (e.g., acquisition). Investors often resist full single-trigger acceleration because it reduces retention incentives post-deal.
Double-trigger acceleration: vesting accelerates only if (1) a change of control occurs and (2) the founder is terminated without cause or resigns for good reason within a set period (often 12 months) after the deal. This is more investor-friendly and common in venture-backed deals.

Drafting tip: define “Cause,” “Good Reason,” and “Change of Control” carefully to avoid disputes and to align with any employment or severance agreements.

4) Treatment on leave, part-time status, or role change

Consider whether vesting pauses if a founder goes part-time, takes extended leave, or changes roles (e.g., from CEO to advisor). If left ambiguous, it becomes a board dispute later. A practical approach is to define “continuous service” and give the board discretion to treat certain absences as continuous service.

Two main documents: what you actually draft

In Delaware C‑Corp practice, founder vesting is usually implemented using one of these structures:

A) Restricted Stock Purchase Agreement (RSPA) with company repurchase option

This is the most common for founders at formation. The company issues the shares now; the company has a right to repurchase unvested shares if service ends. The agreement typically includes:

purchase price per share and total purchase price
vesting schedule (repurchase option lapses as shares vest)
repurchase mechanics (notice, closing, payment method)
transfer restrictions and legends
83(b) election language and acknowledgement

B) Stock option with vesting (less common for founders at formation)

Options can vest over time, but founders generally prefer restricted stock to start long-term capital gains holding periods earlier and to avoid paying a higher strike price later if the company appreciates. Investors also commonly prefer founders hold actual common shares early.

Key clauses to include in a founder repurchase agreement

Below are provisions attorneys typically treat as “must-have” when drafting a founder repurchase agreement for restricted stock in a Delaware C‑Corp.

1) Grant/issuance terms and consideration

Spell out the number of shares, class (usually common), par value considerations, and purchase price. Confirm the corporation is authorized to issue the shares under its certificate of incorporation and that the board approves the issuance and consideration under Delaware corporate law formalities.

Example: “Purchaser hereby purchases 4,000,000 shares of Common Stock for an aggregate purchase price of $4,000, payable in cash, receipt of which is acknowledged.”

2) Vesting schedule as a repurchase option schedule

In restricted stock, “vesting” is drafted as the company’s right to repurchase unvested shares. The agreement should include a clear schedule (often as an exhibit) showing the monthly vesting increments and the cliff date.

Drafting tip: avoid ambiguous rounding. State whether partial months count and how vesting is calculated if the service termination date falls mid-month.

3) Repurchase price (unvested shares) and payment terms

For founders, the market norm is repurchase at the lower of (i) original purchase price or (ii) fair market value at the time of repurchase—often effectively the original purchase price for early-stage stock. This discourages a departing founder from receiving a windfall for unearned equity.

Payment mechanics can include cash, cancellation of promissory notes, or other lawful consideration. Be cautious with deferred payment arrangements; they can raise disputes and, depending on structure, tax or wage-payment issues.

4) Triggering events: “Termination of Service” definition

Define what ends vesting and triggers repurchase rights. Include termination as an employee, officer, director, consultant, or other service provider. Consider whether removal as an officer counts if the person remains employed, and address voluntary resignation versus termination.

5) Company option exercise mechanics (notice and closing)

The repurchase option should describe:

how long the company has to exercise (e.g., 90 days after termination)
how the company delivers notice
when the repurchase closes
how share certificates/DRS statements are returned and cancelled

If the company uses electronic cap table software, confirm the agreement allows electronic notices and book-entry transfers.

6) Assignment of inventions and confidentiality (or reference to separate agreements)

Investors expect founders to have signed IP assignment and confidentiality obligations. Sometimes these are integrated into the stock purchase agreement; more commonly they are separate founder proprietary information and inventions assignment agreements (PIIAAs). If separate, cross-reference them and make continued compliance a condition.

7) Transfer restrictions, legends, and securities law compliance

Include restrictions on transfer (no sales, pledges, or transfers without board consent), a right of first refusal (often in the bylaws or a separate agreement), and standard securities legends noting that the shares are unregistered and subject to restrictions. This helps preserve exemptions under federal and state securities laws.

8) Acceleration language (if any)

If the founders agree to acceleration, incorporate it cleanly:

state what portion accelerates (e.g., 25%, 50%, or full)
define the triggering events with precision
address whether acceleration applies to repurchase options, vesting schedules, or both

Acceleration often interacts with employment or severance agreements; avoid conflicting definitions.

Delaware corporate approvals and recordkeeping

A founder vesting/repurchase structure is only as good as the company’s corporate formalities. For a Delaware C‑Corp, typical steps include:

1) Board consent (and stockholder consent if required)

The board should approve the issuance of founder shares, the form of agreement, and the vesting/repurchase terms. If the corporation has other stockholders at the time of issuance, check whether stockholder approval is required under the charter, bylaws, or any investor rights documents.

2) Cap table and documentation

Record the issuance accurately on the cap table, including the vesting schedule and unvested/vested split. Keep executed agreements, consents, and any valuation support (if relevant) in a clean corporate records repository.

3) Comply with the charter (authorized shares, par value, and class rights)

Ensure sufficient authorized common stock exists. Confirm the issuance price is at least par value and that any protective provisions (if preferred stock exists) are satisfied.

Tax and 83(b): the make-or-break step

Founder restricted stock almost always implicates Section 83 of the Internal Revenue Code. If a founder receives stock subject to vesting (i.e., a “substantial risk of forfeiture”), the founder can be taxed as shares vest unless the founder files an 83(b) election.
