For an investor
Investment readiness. Your business read on the seven things an investor weighs: team, market, product, traction, business model, competition and the ask. The checklist of what they'll ask to see, and which of it you already have. A valuation shown as a range, with every assumption beside it, never as a single number. Red-flag checks that end in a "what must be true" tree of the conditions your case rests on, with a lender's reading beside it.
How you come across. What an investor sees when they look you up, where that costs you credibility, and the fixes ranked by what you're short of.
A pitch, stress-tested. A deck outline drafted from your finished assessment, checked for one pain, one ask and no unsourced figure, then put through a panel of the questions investors actually ask. Any question you can't answer yet becomes a gap to close before the meeting.
A term-sheet reader. Enter an offer's clauses and see the questions to take to your adviser beside each one, and what each party receives across a range of exit values. Understand an offer before you sign it.
