How are current business owners funding their growth?

Paying for capital investments that support growth is expensive in today's interest rate climate, particularly in businesses that rely on a lot of assets. How are current business owners who operate asset-intensive businesses financing their expansion to buy more machinery/equipment/inventory?

1. Raising more equity
2. Traditional Bank LOC/Equipment Loan
3. Other creative financing options (reply in comments below).

Interested in hearing how others are solving this problem!
