Vesting Schedules and Cliff Periods: How Startup Equity Should Be Structured in India

Vesting is the mechanism that makes founder and employee equity meaningful. Without it, someone can join your company for three months, walk away with 30% of the equity, and block your next funding round from a position of doing no further work. With it properly structured, departure is clean and the remaining team keeps building without a cap table liability.
The Standard: 4-Year Vesting with a 1-Year Cliff
The 4-year/1-year cliff structure dominates Indian startup equity because it aligns with the venture capital investment timeline. Most VC funds have 10-year life cycles and invest with a 4–7 year exit horizon. A 4-year vesting schedule means founders and early employees are fully vested by the time most investor exit windows approach.
How the maths works: on a 4-year/1-year cliff schedule for 100 shares:
Months 1–11: 0 shares vest (the cliff period) Month 12: 25 shares vest immediately (the cliff trigger) Months 13–48: 2.08 shares vest per month (75 shares over 36 months)
The cliff serves as a probation period enforced by equity. An employee or co-founder who turns out to be the wrong fit in the first year walks away with nothing. From month 13 onwards, monthly vesting means that partial departures are handled proportionally — someone who leaves at month 24 keeps 50% of their original grant, which is approximately what they earned through the two years of contribution.
Acceleration Clauses: Single-Trigger and Double-Trigger
Acceleration clauses allow unvested equity to vest immediately on specified events. Two structures exist:
Single-trigger acceleration: all unvested equity vests on a change of control (acquisition) regardless of what happens to the employee. This is founder-friendly but acquirer-hostile — when a company is acquired, the acquirer typically wants the key founders to remain and continue vesting. If they're already fully vested on close, there's no retention mechanism. Most investors push back on single-trigger acceleration as a result.
Double-trigger acceleration: unvested equity accelerates only if BOTH the company is acquired AND the employee is terminated or their role is materially changed within a defined period (typically 12 months) after the acquisition. This is the market standard for senior hires and is more palatable to acquirers because it only accelerates equity for employees who are actually displaced by the deal.
Founders should also consider reverse vesting — where a founder's initial shares (issued at incorporation at par value) are subject to a buyback right by the company on a vesting schedule. This achieves the same economic effect as options but through a different legal mechanism.
Vesting for Advisors and Non-Full-Time Contributors
Advisors who contribute part-time should receive shorter vesting periods that reflect their contribution timeline. A common advisor vesting structure: 2-year total vesting with a 6-month cliff, monthly vesting thereafter. The grant size is typically 0.1–0.5% of the company depending on the advisor's seniority and expected contribution.
The mistake many founders make is treating advisors like employees in their vesting structure. An advisor who is genuinely helpful for 6 months and then disengages should not continue vesting as though they're still contributing. A 6-month cliff plus 6–12 months of monthly vesting better captures this: you get the value of the first year of advice, and the advisor earns their equity on the same timeline.
For part-time technical co-founders who are transitioning from a day job, a cliff extension to 18 months (to account for the transition period) is sometimes negotiated — the vest doesn't start until they're full-time.
Key takeaway
Get the vesting structure right for founders first — it's the hardest conversation but the most important one. Then apply consistent logic to employees and advisors, adjusted for their time commitment and contribution level. Document everything before anyone starts contributing.
Frequently asked questions
Can vesting be applied to shares already issued at incorporation?
Yes, through a mechanism called reverse vesting or a forfeiture-linked shareholding structure. In reverse vesting, shares are issued at incorporation (so the founder is immediately a shareholder for legal purposes), but the company has a buyback right at par value if the founder leaves before the vesting schedule is complete. This is economically equivalent to forward vesting (options that vest over time) but uses the share issuance and buyback mechanics. Reverse vesting is commonly used for founders because it allows the company to claim DPIIT recognition from day one with the founder's full stake registered, while maintaining the protection of a vesting schedule.
What is the difference between a vesting cliff and a probation period?
A probation period is an employment law concept — it's the initial period during which employment can be terminated more easily by either party. A vesting cliff is an equity concept — it's the minimum period a person must stay before any equity vests. The two often overlap in timing (both are commonly 6–12 months) but are legally distinct. A probation period affects employment terms; a vesting cliff affects equity. An employee can complete their probation period successfully but still lose unvested equity if they leave before the cliff.
Can an employee negotiate their vesting schedule?
Senior hires (VP level and above) commonly negotiate vesting terms as part of their compensation package. Common negotiations include: shorter vesting period (3 years instead of 4), shorter cliff (6 months instead of 12), credit for prior relevant industry experience (a CFO who joins with 10 years of experience may negotiate for 6 months' worth of upfront vesting as if they'd already 'earned' it), or additional performance vesting milestones where extra equity vests if specific targets are hit.
Does vesting apply to shares purchased in an ESOP exercise?
No. The vesting schedule applies to options, not to shares acquired through exercising options. Once an employee exercises their options and buys shares (at the exercise price), those shares are fully owned and are not subject to further vesting. The exercise converts an option (a right to buy) into actual ownership. Post-exercise, the shares may be subject to a right of first refusal (the company can buy them back at a negotiated price before the employee sells to a third party), but not a vesting condition.
What happens to unvested equity if the company is acquired?
In most acquisition structures, the acquirer has the right (but usually not the obligation) to either: (1) assume the unvested equity — rolling the unvested options or restricted shares into an equivalent plan in the acquirer company; (2) cancel the unvested equity for cash consideration equal to the option spread at the acquisition price; or (3) terminate unvested equity if the employee does not continue post-acquisition. Which outcome happens depends on the terms negotiated in the acquisition agreement and any acceleration clauses in the original option grant.
