Hey, it's Niall 👋

I love scrappy marketing tricks that deliver outsized results.

😍 One of my all-time favorites?

A chiropractor in San Francisco dropped quarters all over the sidewalks.

When people bent down to pick one up, they saw a tiny sticker on the underside…

Did it hurt picking this up?
Call Dalton Chiro (555) 123-4567

That’s it.

Simple, clever, and wildly effective 💪

Let’s do the math:

  • 400 quarters = $100

  • Printing and labor = $100

  • Total cost = $200

And you can bet that stunt brought in way more than $200 worth of new clients 🔥

Today’s sponsor is packed with creative marketing stories just like this — and plenty you can steal. Check them out below 👇

FACELESS VIDEOS

This Forgotten YouTube Channel Probably Earned $1M+

It'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 2021

  • 30 videos total

  • 252M views

Rough 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.

AI VOICE AGENTS

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 feedback

  • Summarize their feedback with AI

  • Post summaries to Slack and send weekly reports

💬 Greg reckons…

Every company would pay for that, like $300 a month

RENTAL ARBITRAGE

$30,000 Per Month Renting Out Underused Assets

📝 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 👍

VIBE CODING

$12K in 4 Weeks From An App He Built Using AI

From 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

TECH SUPPORT

His Boring Business = Passive Income Juggernaut

📝 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.
