I kinda feel like, maybe you already know what you want to do and have it made up in your mind.. but you want someone to reaffirm it for you before you do what you want to do.
I get it, but I'm not that guy to do it for you.
Let us look over what you have mentioned...
Doing SaaS just like you do (being an authority in some domain) it's easy because you can sell it from the day one of writing code and you know your potential customers so you do marketing from the very beginning. But of course, the hardest thing is to be the authority in such a great level as you describe.
It's not hard. You just need to know more than the next lay person.
Does your daughter or wife know how to BBQ? Maybe they know how to heat meat in an oven, but do they know how to smoke a 5lb brisket properly for 12+ hours on 200 degree heat and properly do the charcoal and wood smoke? Probably not.
But you do. Maybe you've done only 3 times. But you know more than her.
And that makes you an authority ( to her ).
Not hard, pretty easy. Right?
And doing SaaS like I do ( which you mentioned above ) is easy because you can sell it from day one because you know your potential customers and do marketing from day 1 ( like you mentioned above ). See why I suggest it??? Why would you do it the complete opposite way and make it hard on yourself?
I taught it the way I do it, because it makes it easy for you and others to market and sell it from day 1. Why do it any other way?
A nice SaaS that has no marketing = no one cares or finds it and you don't make money ( I've built a few of those myself.... avoid this at all cost ).
But.. there is other smart guy with a lot of experience on the forum.. @Andy Black say that the best and easiest way to successfully do a business is just helping people

.
MJ DeMarco (if I remember correctly) created a service for ordering limousines. Was he an authority in that market? I do not think so.
@Andy Black and
@MJ DeMarco are both smart, yes.
But would you say, they are not an authority? Nah, you wouldn't.
So really my advice still rings true for Andy and MJ.
MJ was a limo driver. He was an authority on limos and limo driving over me or you or Andy ( sorry Andy if you were a limo authority too! ). So he created a limo service, right? Seems like an authority creating a service which is what I said. Uhmmm
Andy is an authority on lots of things, like Google Ads and PPC. So he made a service. Seems my logic is still on point, right? Uhmmm
And yes, Andy says to help people. To just help people and you will have a successful business. That's true.
But how are you gonna help someone if you don't know more than them on a topic/subject ( knowing more than the lay person, which makes you an authority )? So again, my advice rings true.
How could you just help someone, if you yourself don't know the topic or issue at hand? That would be the blind leading the blind, right?
In order to help someone, you have to be some kind of authority or else you are just "the blind leading the blind" and that helps no one.
The value you provide in helping someone comes from you knowing how to solve their problem. How are you going to solve their problem if you don't know the problem's topic?
In my case .. I have over 6 years experience in programming. I read regularly forums about programming and so on. In my country (Poland) the biggest problem in this market is that people who want to become a programmer don't know how to start and what languages will be the best for their. I don't know what is the situation in other countries but in Poland there are a lot of wanna-be-programmers because the salaries are much higher than in other jobs. But I think this market is saturated (there are a lot of IT tutorials, blogs, books) and besides even if I created some SaaS to help these people they probably would use it for 3-4 months. I can't find other needs in programming area, maybe I have should been looking in more detail..
Wait, didn't later in your response you say you know an IT guy that went to some forums and helped people and is making money? So your thought about saturation is untrue, right? If he can do it, you can do it.
And if people stay for 3-4 months, what's the big problem with that? At least you are making money and built a SaaS.. the next step would be to figure out how to make them stay for 9 months or more once you build.
You are not gonna build ROME in 3 months on your first try.
I've been a programmer since 1998 when I started to code in Perl. If you can't find a need in programming then you:
1. Aren't programming
2. Aren't thinking
3. Aren't looking
4. Aren't trying
5. Never had an issue or problem in programming yourself, which makes me doubt a few things about your background ( no offense).
BBQ, and other passions like Brasilian Jiu Jitsu, Football, Physics - there are just hobbies but I am not an authority.
Yeah, you brought up the BBQ and hobbies. I was just trying to show you through example how you could do those instead. Not trying to say you should do a SaaS in those, but trying to point out what you could do.
Again, if you do these as a hobby, you probably know more than the next lay person.
My mom quilts as a hobby. I know nothing about it. She is an authority to me. If she built a SaaS or service or course on quilting, she would be an authority over me and could teach me something I would pay for. No one cares that she isn't the oldest most degreed person who is a famous TikToker before they buy her course or SaaS.
If I have question about quilting, I go to her and ask.
If we know nothing about quilting, she is an authority and can teach us something.. right? Money is just the transfer of value. She had value ( info ) that we want and don't know ourselves. That is what SaaS is too.
Referring to your advice and my current situation. The only way for me is just looking for some other hobby (domain) where are a lot of problems and needs, become an authority, maybe create blog with valuable content, meet people and so on.
If you want to chase hobbies, that will be your choice. But that is a lot of time-wasting, if you are chasing hobbies to just build a SaaS.
If you chase them to have fun and learn, that is good.
If you chase them to build a SaaS.. you are missing everything in this AMA I have tried to teach.
On the other hand I know IT guy form my country who has registered in some FB group, was asking about problems and finally has found some need, has created SaaS and earn money ;p
So saturation ( your worry from prior ) is really not a concern. Because IT is just as big as programming with blogs and articles and such available online.
And I never said, that this is the only 1 true way.
There are always outliers in everything.
I know a guy that took 2 shipping containers and made a house and lives in it. Does that mean my dad who is a builder that tells me to own a brick home is wrong? No.
But it also doesn't make the shipping container guy wrong either.
But when it comes to resale value 20 years from now, potential fire and tornado/hurricane issues, insurance costs, heating and cooling issues, etc... one of these solutions may end up being the better choice in the long run over time.
Both are not wrong, but one tends to come up a lot better option when you step back and look from the 50,000 foot view of things.
Also, the idea of "shipping container homes" is an easy sell to lots of people, just like browsing Reddit or FB groups is an easy sell. I mean, how hard could browsing Reddit or FB be? It's a lot easier than having real authority in a subject. Just like slapping 2 shipping containers together for $8k and cutting out windows seems a ton easier than building a brick home for $300k and lots of contractors and paperwork.
Can you live in both ( or make money from both ) ideas? Sure. Is one of them a better long-term solution? Yes
That is what this AMA is.
That is what my advice is.
The problem with your friend is, he built something based on someone else's need ( someone in that FB group ) and made some money. When he gets stuck and needs to pivot or add on or change things.. what is he going to do? Ask people in that FB group again?
What if they are no longer there? What if FB takes away the group. What if they grow tired of his questions and not answer him? What if they give him the wrong advice and he follows it because he doesn't know any better since he isn't an authority?
I could go on, but I think you see my point.
