A little off topic but my advice is to have any agreements be explicit and in writing. Probably obvious to some, but it's easy to get a good conversation going,

A little off topic but my advice is to have any agreements be explicit and in writing. Probably obvious to some, but it's easy to get a good conversation going, just go with the flow, and not follow up afterwards with an explicit agreement around terms/expectations. In a startup this can be even more important because you may find out they don't have the resources to give you what you want.
