Hello,
There are a few things to consider.
For the bank loan:-
PROS
- you can retain full ownership.
- Fixed Repayment Terms
- interest payments on business loans are often tax deductible.
CONS
- Debt obligation; you have to pay back the loan with interest which can strain your cash flow.
- Collateral: some banks will require collateral which can put your company assets at risk.

Private investor:
PROS
- No repayment obligations
- potential for growth capital
- expertise and network: investors can bring valuable expertise & connections to your business and can help it grow.
CONS
- you have to give up a portion of your ownership and control of your company
- New investors might have a different vision and expectations for the business
- investors typically expect a return on investment which can create tension in the company and eventually pressure your to expand and grow or sell the business or go public
Other things to factor in:
- Cash flow; assess your company’s ability to handle the loan repayments without compromising any operations
- Ownership Preference; Decide how much ownership and control you want to give up
- Risk Tolerance; Consider the risk of taking on the debt vs. the risk of bringing in an outside investor.
- Long term goals; align your choice with your long term business objectives.
