Forming a productive co-founder team is a critical step in the process of building a company, yet many people simply jump into co-founder relationships without ever making sure their counterparts are on the same page. For example, just because your co-founder is a long-time friend or family member doesn't mean that they want the same things that you do.

To help potential co-founders identify issues and discuss important topics early on, Jessica Alter (co-founder of FounderDating and Entrepreneur In Residence at Social Capital LP) created a list of 34 questions for co-founders to discuss in a blog post titled Questions to Ask Potential Co-founders: The Master List.

Below we've highlighted the list of questions, broken into four categories:

Personalities and Incentives

  1. Why do you want to build a startup (in general and in particular, right now)?
  2. What motivates you (e.g. a technical challenge, an overall problem, helping the world, etc.)?
  3. What do you do with your free time? (e.g. how do you unwind? How do you deal with stress and big challenges?
  4. What do you think I’d be most surprised to find out about you?
  5. What are our respective personal goals for the startup (e.g. a sustainable business that is spinning off cash and running it forever or high growth and some type of liquidity event)?
  6. Will this be the primary activity for each of us?
  7. What is the expected time commitment (now, in 6 months, 2 years, etc.)?
    1. Are we allowed to take on anything outside of the company?
    2. Would we sell this for $5mm? $100mm? Are we waiting for the billion dollar exit?
  8. Is there a part of our plan that we are unwilling to change (e.g. the product being built, the market being addressed or some other aspect of the company)? Pro-tip: the only guarantee is that things will change, so if someone isn’t open to that there is a problem.

Personal Priorities

  1. What are our personal cash needs in the short term?
  2. Are we both going unpaid and when would this change?
  3. If you’re not able to go full-time now, under what circumstances would you be able to start working on something full-time?
  4. Do we want to raise outside money?
    1. If so, how much – now, in 6 months, 2 years, over the life of the company?
  5. Where do we want the business to be located?
  6. Get a sense of personal commitments that the person has so as to better manage your time and their time (i.e. are you married? With/without kids?)
  7. Have you ever failed at anything?
    1. If so, how did you handle it and what did you learn? If not >> big red flag!
  8. Talk about times you both did something you had never done before – how did it get handled and what was the outcome (could be technical or non-technical (e.g. I ran the internationalization of a site; I scaled a site to 5M users)?
  9. The Spouse Test- given how much time you’re going to spend with a cofounder, if you have a spouse or significant other you should have them meet the potential cofounder. Not only do they know you better than almost anyone and can give you a second opinion, but also they should know the person you’re going to spend a lot of time with.

Working Styles and Culture

  1. If you had to come up with 3 words to describe the culture you want to create, what would they be (e.g. open, hard-working, eccentric)? Pro-tip: if you’re really serious and far along go visit few office spaces together to get a sense of what each of you likes work environments wise and why.
  2. What values do we want to instill in our employees?
  3. If you could pick 2 things to change and two things to bring with you from your previous companies, what would they be and why?
  4. How much equity are we allocating for future employees?
  5. Who do we think the first 5 hires will be?
  6. Describe your working style to me in a few words?
  7. What are some of the products you love and why? Pro tip: this will help you get a sense for they appreciate and even aspire to – design, product, tech, biz strategy, etc.
  8. How do you deal with conflict? Compromise? TIP (not even a pro one): the only real way to know this is to do a side-project or start working together. Fights are healthy, how you get through them is the question.
  9. Ask for references or just back channel them! Don’t be afraid to do this, it’s important! We reference everyone in the FD network (yes, it’s true) and we still tell members to reference their potential cofounders before tying the knot.

Roles and Responsibilities

  1. What areas do you see yourself definitely wanting to be point-person on for the first 12-18 months?
    1. What about me?
    2. What are the areas you know you’re not particularly good at?
  2. What do you think I am best at?
    1. What do you think I need support for?
    2. How will you help me succeed?
  3. How will decisions get made?
    1. Can you outvote me?
    2. Can either of us fire the other?
    3. If one of us gets fired, what do we leave with?
  4. Why do you think we’ll be good together?
  5. Some of the legal stuff…
    1. Have you ever been fired, gone to jail, or done anything that would materially impact your time with the company?
    2. Do you sit on any boards of companies and do you have any conflict of interest with our project?
    3. Is there a ‘no compete’ clause that is active at this time?
    4. Will any of us be investing cash in the company? If so, how is this treated? (e.g. debt? convertible debt? Does it buy a different class of shares?)
  6. Have you worked and/or managed diverse teams and if so, how?
  7. How do you think we should give feedback to each other (and the team)?
  8. Who is going to be CEO (and why)? Are we both comfortable with this?
  9. What’s the equity split and why? Are we both comfortable with the reasoning behind this decision?
