Those founders who are so comfortable sharing their ups and downs and who desire discourse and advice across the cap table are clearly the ones who are in it to win it.

So comfortable? Maybe. A start up is about leaving your comfort zone, whether you want to or not.

Practical and smart? Absolutely. Aside from adding (experienced) voices to your talent pool, such "marketing" helps with any future needs for more money. Being less transparent and asking for more simply isn't a reasonable expectation.

As a side note, this format reminds me of the comms framework in the book "Smart Brevity."
