The main sources of funding for an aquaponics business are personal savings, credit cards, bank loans and angel investors. With regards to bank loans, banks will want to review your business plan and gain confidence that you will be able to repay your loan and interest. To acquire this confidence, the loan officer will not only want to confirm that your financials are reasonable. But they will want to see a professional plan. Such a plan will give them the confidence that you can successfully and professionally operate a business.
The second most common form of funding for an aquaponics business is angel investors. Angel investors are wealthy individuals who will write you a check. They will either take equity in return for their funding, or, like a bank, they will give you a loan. VC funding is not appropriate for aquaponics businesses as VC seek quick and massive returns from high tech ventures.
