What did you do to find a cofounder or the team that you are working with right now?
Your team is going to make you or break you. First, take inventory of your skills and assess how much capital you have (technical, social and financial). Then, assess what complimentary capital you'll need (i.e. bringing on a technical co-founder if you're not technical). Once you've accounted for the technical aspects, start thinking of what type of cultural attributes you would like in your team (very critical). Finally, write the description down and then start recruiting. Take your time and begin with your network first, and then start expanding to 2nd and 3rd degree connections.
Once your team is on-board, put together an operating agreement (jointly if possible) and Implement a 6 or 12 month cliff. This will protect your business from any risks if things go sideways for any reason.
Take your time with putting together a team. You're going to be married to these folks for a long time.
