Finding a co-founder with relevant skills and knowledge that are different to yours lets you focus on what you’re best at.
For example, you might be selling a product you invented, or a service that uses a particular skill or talent you have, but not have any hands-on experience of running a business. If so, you might want to work with someone who has business and management skills, and can look after things like financial planning and recruitment.
Consider working with several partners in a team. You’ll be able to share responsibilities including risk, getting funding, expertise and sharing contacts.
