First identify who needs money: the company, an owner or both. Then explain what the funds must achieve and how progress could be assessed. Growth, reorganisation and shareholder liquidity are different objectives.
An investor brings an ownership relationship and governance expectations, not just cash. Equity and debt are different arrangements with different implications. Prepare reliable information without exaggerating the opportunity, and define what you would and would not want to change. A useful investment structure responds to an explicit need rather than a vague wish for a new partner.
