Lack of a business plan is a surefire road to perdition.Question; do you have a full business plan?
Back in 1978 I had a similar dream like yours: to found s company which would manufacture and sell electronic products that I designed.
I actually incorporated a company, invested several years of savings plus additional funds that my father and some relatives loaned me.
The products were excellent, at a reasonable price and worked as promised. Yet, two years later, after toiling 24/7, the company went bankrupt. I lost all my own hard earned savings. My father forgave the debt, but I had to sell my vehicle to pay the relatives. I ended completely penniless.
What was my mistake? The same one that you are committing right now: I didn’t have a business plan. It was a brutal life lesson.
I won’t get into the hundred different details that a good business plan requires. But I would advise you at the very least watch the TV series “Shark Tank”, so you will have a slight idea of the grueling questions that a professional investor could ask. The professional investor will be more challenging, I can assure you that.
