Natural Finance uses the "obvious/most elegant" definition of natural.  It is a variation of truth:
functioning or occurring in a normal way; lacking abnormalities or deficiencies; "it's the natural thing to happen" (from google - define: Natural)
Natural Finance provides borrowers with the most efficient and cost effective lending terms, which continuously reflect and reward the success of the organization.  It further provides the borrowing enterprise with a currency it can freely offer without compromising other investors, and frees the founders to choose a mandate and purpose.

Natural Finance provides investors with liquid high yielding loans superior in security to any other corporate investment with the opportunity to reinvest/rollover at privileged terms when repaid.  They are guaranteed priority at the time of investment, and can never be diluted.
