Super Volatile

Most non-technical founders think they're great product people because it's so easy to be an ok product person. You're going to have to decide whether you're dealing with a great product person or not. A great product person:

• Is relentlessly focused on making sure you're making the right product for the right market.
• Has a clear vision of what success for your product looks like and is probably addicted to metrics.
• Knows when to cut features and can prevent you from wasting time on developing irrelevant features early on.
• You can point to any piece of a product and ask "Why?" and they have an answer.

Worth reading before engaging with somebody on a new venture. Interestingly, most of this advice seems to be also applicable to product owners in non-startup environments.
