Stock Option financial

"The stock options were granted on November 10, 2020, and are fully vested."

A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.

fully vested financial

"The stock options were granted on November 10, 2020, and are fully vested."

vest in three equal annual installments financial

"The stock options were granted on September 20, 2023, and vest in three equal annual installments"

general partner financial

"which is the general partner of Tene Growth Capital 3 (Fund 3 G.P.) Projects, L.P, which is the general partner"

A general partner is the person or firm that runs an investment partnership and legally represents it — they make the day-to-day decisions, choose which assets to buy or sell, and are responsible for the partnership’s obligations. Investors care because the general partner’s judgment, risk-taking and fee and profit-sharing arrangements determine both the potential returns and the level of exposure to losses; think of the GP as the ship’s captain whose skill and honesty shape the voyage’s outcome.
