Understanding Startup Equity distribution and tools for calculation

Startup Equity refers to the value of your stake in the startup. Initially, when the startup is just an idea, it belongs to only one person. When you start building this idea into an actual product, you realize you require more people and more resources.


You might be good in technology but not in negotiation. So, you always need someone else who can complement your skills and help you build your startup. This person would be your co-founder. Once you get hold of this person, there is one big question. What do you give him/her in exchange?

Your startup is just in the initial stage now and all you have to offer is your Startup equity. Till now all the Startup equity was concentrated on one place. From here on, Equity dilution will take place.  You would need to share your precious pie with other people.  


At later stage of the startup, outside funds are required. The people who would fund your startup are known as Investors. For investors too, you would need to share your Equity Startup. Here again, your Equity will be diluted.


Initially, not much revenue is generated from your startup. So, you are not able to offer higher salaries to your initial employees. To compensate for lower salaries, founders offer their employees a share in their Startup Equity. This is usually called Sweat Equity or Employee Stock Option (ESOP).
