Someone Cloned His Simple Project And Makes $2K/Month
VinnyFounder of CoverLetterGPT $550 monthly revenue
Vinny tweets…
my simple GPT wrapper has made me $9,567
He explains further…
CoverLetterGPT is a GPT wrapper that generates personalized cover letters based on the user’s uploaded CV and job description. The function that seperates it from just using chatGPT is that users can edit cover letters inline with AI assistance, as well as manage all the different cover letters they’ve generated.
It’s super simple, and it’s even open-source!
I launched it in August 2023 and it’s been a steady source of passive income since.
Now earning him about $550 each month 
The open source part is important, especially when you see this tweet from Vinny…
One guy even cloned it for a French audience and makes 2k/month
Definitely worth trying this for other languages.

$25K/Month From His Subscription Service
Will GriffithsFounder of Hatchly $25,000 monthly revenueFrom an interview with 29-year-old Will Griffiths 
Currently we are making ~$25k MRR… monthly costs are around ~$5-7k.
The business is Hatchly, a subscription design service.
Will was freelancing via Upwork, but found that to be a treadmill with lots of admin 
So he started Hatchly in 2020…
I adopted a subscription model to ensure consistent quality, service delivery and 20x less admin!
The initial service was started with a minimal budget (probably only about £100 in subscription fees).
Got his first few clients by offering low prices and leveraging his LinkedIn network 
Looks like he now has a small team of contractors and the business is growing nicely.

7 Startup Ideas Backed By 100,000+ Reddit Upvotes

Remote Team Bonding Subscription Boxes
Marshall explains
Remote work is here to stay, but workplace connection is evaporating. Companies want a digital culture without awkward, forced Zoom calls every week.
Simple idea: A subscription box for distributed teams — think interactive games, shared snacks, theme days, handwritten notes, swag, and rotating hosts.
Repeat customers: As more companies go fully remote, HR budgets are shifting here.
Sounds like an easy thing to promote on subreddits like r/WFH

Subscription Box For Cats = $30,000 Per MonthHe’s Earning $50-100 Every Day with Arbitrage Betting
Jcc5950Sports Bettor $75 approximate daily revenueJcc5950 reports that he’s earning $50-100 per day with arbitrage sports betting 
Example…
1. I bet $16 on Fanduel that Kyle Schwarber will hit a double in tonight’s game for a total payout of $120
2. I bet $100 on Bally that Kyle Schwarber will NOT hit a double in tonight’s game for a total payout of $118
3. I have wagered a total of $116 on both outcomes, and since one outcome must happen, I will either make $2 if he does not hit a double, or $4 if he does…
In this example, I am going to profit at least $2 and at most $4, and the whole thing took me 10 seconds. I repeat this 20-30 times a day, and by the end of the day I have made a nice profit.
Note that sportsbooks don’t like arbitrage betting and try to prevent people from doing it, but clearly some folks are still having success.
Also, gambling is addictive and ruins lives, so be careful 
Jcc5950 again…
This is my third month and I am on track for 3K this month. Made 4.4K total in my first two months…
I started with around 23K spread across 10 different books. It has now grown to just under 28K.
$17K Per Month From Their Niche Community in 1 Year
Professor SolCo-founder of NeuroSpicy Community $17,000 monthly revenue
My friend Sebastian launched the NeuroSpicy Community last year…
A supportive space for people with ADHD and Autism, offering resources, coaching, and connections to foster personal growth and shared experiences.
He partnered with TikTok influencer Professor Sol to reach the initial audience.
Sol had ~100K followers on TikTok at the time, was monetizing via 1-on-1 coaching calls but that wasn’t paying the bills.
Initial launch was 50 lifetime memberships at $300 a pop, earned them $15K within 2 weeks
Then they switched to $25/mo for new members.
A year later they’re earning $17K per month and the community is growing steadily, most new members finding them via TikTok 
Sol takes care of the content creation and is the face of the business. Sebastian handles all the back-end stuff.
Is there a niche influencer you could team up with to start a paid community?

Generating Affiliate Revenue via Reddit Parasite SEO
Mike Futia tweets…
Google Search is so cooked
keyword: best air purifiers for home
ranking #2: a Reddit spam post from “helloimlupphie”
written by ChatGPT
filled with links to their own affiliate site…
Here’s the post on Reddit, probably gets 1000’s of views every month
That affiliate site is likely getting less traffic from Google nowadays so they’re posting content to Reddit that links to their site.
This is known as Parasite SEO 
Assuming their content is actually legit and well-researched – and they can somehow avoid the Reddit mods – I’d say this is fair game.
As Mike puts it…
don’t hate the player hate the game
If you have a content site yourself, you could try this to get more traffic
Or offer to make Reddit posts like that for established content sites, charge them per post.

Chance-Cup5862Entrepreneur $6000 monthly revenue Chance-Cup5862 writes…
[I’m] uploading vectors to different graphic contributor platforms like Canva, Adobe Stock, Shutterstock, Vecteezy, Freepik, Noun Project, Flaticon and Alamy…
There are more then 50k vectors in these accounts…
I’ve built a team of graphic designers remote and physical who create vector illustrations based on my guidance and market trends…
I’m earning an average $6000 a month which is completely passive from last 11 months and haven’t uploaded any new vectors.
In the comments…
there is a high demand for Regional themed vectors. They can really help you stand out and rank within fast in your target audience.
Sounds like a lot of work up front but clearly a profitable side hustle in the long run
Try this yourself if you have graphic design skills or can hire someone to create vectors inexpensively.
His Niche Shopify Store Earned $3 Million Last Year
Carlos UgaldeFounder of House of Chingasos $3 Million annual revenue
Paywalled story about Carlos Ugalde…
He got laid off at 52 years old, no digital marketing experience but he decided to launch a Shopify store, House of Chingasos…
he wanted to combine Latino and meme culture through clothing. Within 90 days, he went from $2,500 in sales to $54,000 a month by following this strategy:
• Open up a Shopify store
• Upload 10 basic designs
• Connect the e-shop to Printful (a print-on-demand company)
• Start running Facebook ads immediately
Sounds like he was relentlessly testing his ads 
He launched quick, low-budget campaigns to test different designs and messaging… If a design or message underperformed, it was scrapped. If it took off, it was scaled.
This rapid-fire approach allowed Carlos to make data-driven decisions, double down on what worked and continuously refine his brand for a growing Latino audience.
Carlos did it for a Latino audience, starting ~5 years ago.
What other audience could you do it for?
