There have been a lot of people talking about "boring", lesser skilled business opportunities in the media lately. Things like laundromats and vending machine businesses which have lesser skill and equipment demands compared to starting something like engineering consulting or a blood testing lab.
What are the money making ideas that you have that most people who fit the HN demographic could likely start and make some money doing?
Passive income businesses or businesses where an average 16 year old can put in $1 and get $1.25 out are liable to get 'disrupted' by someone who is willing to put in $1 to $1.15 out or someone savvy who can put in $0.90 to get $1.25 out. Terrible market and it's exactly why you see them on YouTube selling courses on how to do it or even just saying their entire business plan because it's that brain-dead.
They are just bad businesses because they have no defensibility or IP generated. Yes, you don't have to work to earn necessarily but you are still hitched quite heavily to being hands-on.
My opinion is a good "boring" business is something that passes unremarkably at Thanksgiving and will never be on magazine covers, also good competition to prove the market is strong enough to have another entrant
If you can tell someone what the business is and they go "So anyway"... fantastic business. You don't want any venture-backed companies whose business plan starts and ends at a snow shovel and a pile of money. You will lose unless your plan is the same and you either have a bigger pile of money or your competitor is much worse. The ideal space is likely an established market with sleepy / stagnant competitors so you can carve off a few percent by addressing what the market is not and having a few million+ a year in revenue.
