What is an option pool
Also known as: employee option pool, ESOP pool
Definition
An option pool is a block of shares reserved for future employees' options. If it is created before the investor's money, existing shareholders pay for it.
Why it matters
An option pool lets a young company hire people it cannot pay a full salary.
Common mistakes
Believing the new investor shares the cost of a pool created inside the pre-money. It comes out of the existing holders only.

Who pays for a 10% option pool
Illustrative numbers: a fictional clinic booking app raises ₪1,000,000 at a ₪4,000,000 pre-money valuation, and the investor asks for a 10% pool.
- 100% - 20% - 10% = 70%
Pool before the money
The investor ends with 20% and the pool with 10%, and the founders keep what is left.
- 80% × 0.9 = 72%
Pool after the money
The founders hold 80% after the round, then the 10% pool dilutes every holder.
- 20% × 0.9 = 18%
Pool after the money
In that case the investor is diluted too.
- ₪100,000
The difference
Two points of the company at the ₪5,000,000 post-money valuation.
- ₪3,500,000
The difference
With the pool inside the pre-money, the founders' 7,000 shares are priced at ₪500 each.
The headline says ₪4 million. The founders' shares are priced at ₪3.5 million.

- Founders70%
- New investor20%
- Option pool10%
Created before the money, a 10% pool leaves the founders 70%. Created after it, they keep 72%. The difference is 2 points of the company, ₪100,000 at a ₪5,000,000 post-money valuation.
Definition
An option pool is a number of shares the company sets aside under an option plan, to grant as options to employees, advisors and consultants. Until an option is granted, the reserved shares belong to no one, yet a fully diluted cap table counts the whole pool. Options granted from it vest over time, and options that lapse when someone leaves usually return to the pool.
Why it matters
It is real dilution, and the timing decides who pays for it. When investors ask for the pool to be created inside the pre-money valuation, it comes out of everyone who holds shares before the round: founders, earlier investors and existing option holders. The new investor's percentage stays whole, so the founders' real price per share is lower than the headline valuation.
Improvement tips
- Size the pool from a hiring plan: which roles you will fill before the next round and what grant each needs.
- Negotiate the pool size in the term sheet together with the valuation, because a bigger pool inside the pre-money lowers your real price.
- Show candidates what their options could be worth at a few company values, not only their percentage.
- Before the plan is adopted, ask your accountant which tax track the options will use.
Common mistakes
- Creating a pool far larger than the hiring plan, which dilutes the founders before anyone is hired.
- Assuming options dilute no one until they are granted. A fully diluted cap table counts the whole pool from the day it is created.

Equity
Equity is ownership of a company, measured in shares and percent. On a balance sheet the same word means book equity: what the business owns minus what it owes.
Dilution
Dilution is the fall in existing shareholders' percentage of a company when it issues new shares. The percentage drops, while the stake's value can rise.
Vesting
Vesting is a schedule under which shares or options granted to you become yours to keep or exercise step by step, as long as you keep working for the company.
Pre-money Valuation
Pre-money valuation is the agreed value of a company just before new investment comes in. It sets the price per share and how many shares the investor receives.
Cap table
A cap table (capitalization table) shows who owns how many shares and options in a company, and what percentage each holds on a fully diluted basis.

Anna
Beautician
After I finished a cosmetology course at a leading company, I was confused. I didn't know how to open a business, what to sell from home, or how to bring in clients. Since I reached out to Mobius, everything has changed. We built an organized plan with clear steps and no unnecessary risks. Today I see results, and I'm growing and developing every month.

When I finished a massage course, I imagined a different world. I found out it's a hard field, and financial stability isn't easy to find. When I came to Mobius, something changed. We started an organized process and built a business plan. Without Mobius? I probably would have given up. Today I believe in myself and in my own path.
