Replace “human resources manager” with your own job. Or, focus on skills or hobbies you have, or a life transformation you went through.
Basically leverage whatever personal experience you can 
Once you’ve settled on an idea for a product…

His Boring Business = Passive Income Juggernaut
Zarko291Computer Consultant $15,000 monthly revenue
Zarko291 writes…
15 years ago I started my own computer consulting firm. It was later in life (I was 45), and I knew I didn’t want to trade hours for money forever…
10 years ago I started going after only small businesses (20pc’s or less). I signed them up for my unlimited remote support package at $30/PC/mo.
Now I have so many customers that I pull in $15,000/mo and I probably do 12hr/wk of work… I’m semi-retired at 60 and pulling in full salary.
Sounds like a solid local business any tech-savvy person could start 
Zarko again…
I have no certs, no degrees, no education in IT. My degree is in geology. IT just comes easy.
His advice for finding clients
I’m not marketing myself to mid size businesses that need a lot more advanced tech. I just do small business. They all need the same things…
Join a local networking group and get to know some small businesses.
$12K in 4 Weeks From An App He Built Using AI
Sebastian VolkisVibe Coder $12,000 revenue in 4 weeksFrom Indie Hackers
One is TrendFeed…
AI-powered content discovery platform that identifies viral trends for content creators.
Sebastian Volkis is the solo founder, a “self-taught developer who learned to code through AI tools” 
His progress…
Initial prototype built in just four days using AI…
February 2025: Development started
March 2025: Public launch
March 2025: Reached $12,000 in first four weeks
Sebastian tweeted…
This goes to show you just need to build a simple app idea nothing complex
And…
Its actually crazy to me how many people still think that Ai coding is not possible, and can’t build useful tools
Yes you have to be patient with it, and yes a dev could do a better job, but for people who cant code this is a game changer
$30,000 Per Month Renting Out Underused Assets
Angel RodriguezYacht Rental Business Owner $30,000 monthly revenue Tim Richard writes about 27-year-old Angel Rodriguez…
a former car salesman who built a $30K/month yacht rental business in under a year by financing boats and partnering with owners…
He financed his first yacht for around $5,000/month.
He lists it for about $1,800/day on Boatsetter…
Hit $20K/month by month 3…
Booked 15–20 days/month = $27,000–$36,000 in revenue…
Estimated profit: ~$14,000–$22,000/month per boat
Boatsetter = Airbnb for boats 
Tim notes that this “rental arbitrage” can work for other things too, such as RVs, dirt bikes, paddle boards, etc.
The blueprint
→ Find underused assets
→ Negotiate a fixed cost or finance it
→ List on a rental marketplace
→ Create a system around it
This kind of business is also quite future proof, something AI won’t be disrupting anytime soon 
Companies Would Pay $300/Month For This AI Service
A recent video from Greg Isenberg and Tony Ge
Tony basically built an AI voice agent (demo at the 0:20 mark) that cold called luxury watch dealers and made them a lowball offer for a specific watch.
He shows that one dealer accepted a $19,000 offer for a $33,000 watch…
[So I can] go buy this watch for $19,000… then go on the secondary market and sell it for like $22,000 and make like $3000… and then do that at scale… you can automate this even further
Several commenters note that cold-calling with AI may actually be illegal in some states 
But at about the 21-minute mark Greg throws out another AI business idea…
Set up a number that customers can call and leave feedbackSummarize their feedback with AIPost summaries to Slack and send weekly reports Greg reckons…
Every company would pay for that, like $300 a month
This Forgotten YouTube Channel Probably Earned $1M+
Travel Alone IdeaYouTube Channel $1 Million estimated revenueIt’s a faceless channel called Travel Alone Idea.
Simple POV-style videos of traveling solo in Japan 
Train journeys, capsule hotels, etc.
First video Oct 202130 videos total252M viewsRough estimate of earnings just from YouTube ad revenue = $500K to $2 million 
(Weirdly, there hasn’t been a new video posted to the channel for almost 2 years.)
Clearly there’s an appetite for faceless travel videos like these 
Take a few trips to nearby hotspots and make some yourself.
Post them on YouTube and see what the response is like 
If they do well, you could also monetize via sponsorships, affiliate links, etc.

One Question That Unlocks Hidden Business Opportunities
Shaan Puri writes…
I read a great quote the other day from Ben Kuhn (the CTO of Anthropic) about finding your thing: “what does it seem like everyone else is mysteriously bad at?”
I love this.
For me, I always wondered why other people are so bad at explanations…
For 10 years, I tried to make being a founder my thing. I was a B+ at it. But in the real world, B+ doesn’t get you jack sh*t.
Then I started podcasting for fun. I started writing. I started doing the thing I thought others were mysteriously bad at (explaining things).
The podcast took off (100m+ streams), my twitter blew up (450k followers), and my newsletter grew fast (sold in 1 year for millions of dollars).
That’s a powerful lens for uncovering your edge: pinpoint the skill you take for granted but others struggle with, and you’ll spot where opportunity lives
Shaan again…
instead of asking “what am I great at?” – just start to pay attention to “what does everyone else mysteriously suck at?”
Examples of AI Agents That Could Earn Big $$$
Pat Walls tweets…
Please comment on this thread with a recent “AI agent” you deployed, what it does, and how you built it…
I want to hear how people are ACTUALLY using AI agents to improve their life / save time / make more money.
Check the replies for agents that could become businesses
For example, Logan Brown replies…
Built an AI nutritionist that texts me. Creates meal plans based on goals, checks in throughout the day, keeps track of calories/macros when I text it what I’m eating (including pictures)
It’s nice because it’s not an app. Most consistent I’ve been with my diet in years.
Turn that into a service and sell to health coaches and nutritionists, to help their clients stay on track
$2000/Month Selling Amazon Items on eBay
SammyeBay Seller $2000 approximate monthly revenue Sammy writes…
I’ve made $1K–$3K/month consistently on eBay for 8 years. No ads. No inventory. No upfront costs. Here’s exactly what I do…
1. I create a business eBay account.
2. I list 2–3 random items manually (books, mugs, etc) to warm it up.
3. A few days later, I start listing items from Amazon with a markup.
4. Every time I list something, eBay gives it a boost in search.
5. Some sell. Some don’t. I end the stale ones and relist them to trigger the boost again.
That’s it. I list in volume, and let the algorithm do the filtering.
People ask, “Why would anyone buy it if it’s cheaper on Amazon?” The answer is simple: most people don’t compare. They search, see it, and buy it. Convenience wins.
I don’t try to pick winners. I just let the system decide. I don’t bet on one product. I run the play 10,000 times.
Sounds legit but Sammy admits to being the founder of a $200/month automation tool that helps people run this kind of business.
So take it with a grain of salt
