For questions too small for a call but too specific to guess at.
Send me one question about fundraising and you get a proper written answer within 48 hours. Not a one-liner, a real answer with the reasoning behind it.
Works well for:
Sanity checking an email before you send it
Whether a term you were offered is normal or not
Whether a particular investor is worth your time
Any question you have been quietly googling and not finding a straight answer to
One question per booking. Ask it specifically and you will get a specific answer back.
