Do business fail for lack of capital?

That can definitely happen but a better way to look at it is this!

The proximate cause of capital is sales skills.

Capital equals money.

Money is required for owner profits and for fuel to keep the business running.

If the proximate cause of capital ie money is sales, then your business is actually suffering from a lack of sales skills.

Sales skills are required to secure financing from investors.

Sales skills are also required to get revenue and recurring income from customers.

Don’t whine that your business or business idea is suffering because of a lack of capital.

Your business and business ideas are dying because you don’t know how to sell.
