In a startup company, there are 4 people involved, and all of them work on a sweat equity basis. Here are the people and their role:
Person #1: Helped shape the idea with person #2. One of the two initial people in the project. Has a background in computer science and entrepreneurship. He is responsible for server-side development, web&graphics design and is actively involved in other aspects in business, helped and helping to write the business plan, marketing and other business decisions.
Person #2: Helped shape the idea with person #1. One of the two initial people in the project. Has a background in finance. He is responsible for marketing, finance and payments. Initially wrote the business plan. He is involved in marketing and other business decisions as well.
Person #3: Brought by person #1 a month later. Has a background in science. He is responsible for the client-side coding and web design, and is pretty experienced in that. The only other technical person in the group other than person #1. He is not involved too much with marketing and other business decisions.
Person #4: Brought by person #2 two months later. He has a background in finance and has experience with non-profits which are a part of the business. He is well-connected and expected to bring new potential customers & VCs on board. He is also involved in marketing and other business decisions.
The product prototype and the business plan is ready, person #2 and #4 will spend a bit more time in the next 1.5 months than #1 and #3 to get in touch with connections and see the potential possibilities. Everybody work equally after the next 1.5 months.
Considering everybody's role in the company, what do you think would be a fair share of equity among these people?
Thanks for your suggestions.
