[bitonomics]

- Where can you find a good co-founder ? Best if it is someone you have known for a while. If not meet ups and places where people with common interests gather.

- What share would you offer him (already working 2 years on the project already and invested money in it etc.)? It depends on what type of skills they bring to the table. A vesting schedule is best so that over time they are compensated, but if they walk away a few months into it you aren't screwed.

- How would you organize it legally ? Depends on how your projects are organized. LLC or C Corp managing the other entities probably works, but there are a lot of variables and this is where a lawyer would come in.

- Would you meet him in person first ? ABSOLUTELY! This is basically a marriage...you don't want to start that on a blind date.

- Are there other things you should be careful for ? Be careful of over committing equity and not knowing the person well enough.
