One of the best things for parents to do is to let kids run their own business. 

In one of The 2x2 Podcast episodes with Leslie Elliott, we found ourselves talking about why certain business ideas actually work better when kids run them – and how these small, overlooked opportunities turn into real money for their college fund. 

Some businesses work better when kids run them – not despite their age, but because of it.  

Kids operate with advantages adults no longer have: 

They’re also playing a completely different math.

Imagine a business that makes $8,000–$10,000 a year. 

It won’t replace income or justify the effort, so it fails adult math. 

But for a kid, that same business is meaningful.

It’s independence, savings, confidence, and learning experience. 

What’s insignificant to an adult can be transformative to a kid.

That gap is why kid arbitrage works so well.

Adults walk away because the effort isn’t worth it. Kids step in because it absolutely is.

And this kind of arbitrage works best for kids who already show entrepreneurial instincts, like Leslie’s son, James.

Giving kids room to run small businesses early on, with the right parental guardrails, is often the fastest way to nurture that spirit. 

Now, let’s look at some ideas Leslie and I brainstormed. 

Arbitrage: Emotional resonance + delivery density 

Grove Flowers is James’s most recent and most instructive business. 

It started when he and Leslie delivered flowers to his grandfather and neighboring residents in assisted living. The reaction wasn’t polite gratitude. People nearly cried. 

That emotional response was the validation that the business would thrive. 

The model became obvious: 

Pricing became subscription-based. Margins landed around 45%. 

This business works because a kid runs it. 

An adult delivering flowers is a service. A kid delivering flowers is an experience. 

That emotional premium is pure kid arbitrage. 

Arbitrage: Small tasks that never justify hiring help 

Every household has a list of tasks that are constantly annoying and never done at the right time. It adds to the parents’ stress, but they’re all too small to justify hiring help. 

Think unloading dishwashers, folding laundry, restocking pantry items, and packing lunches. 

These tasks don’t particularly require skill, and coordinating help feels harder than doing it yourself. 

This is where kid arbitrage works. 

A kid doing 30 to 45 minutes of quiet hour work a few days a week creates real value for households that don’t want a nanny or house manager.

They can get paid $40 to $60 a week and serve up to 4 homes nearby. 

The work fits neatly into their school schedules, and parents get relief without hiring full-time help. 

Not glamorous, but extremely useful. 

Arbitrage: Timing and tolerance

This idea came from my stepson Sajan, who ran a small power-washing business in his neighborhood. 

He didn’t grind all summer. He worked only during high-demand moments, like pollen season and fall leaf buildup. Sajan priced driveways by the square and managed to earn $500 when he did it.

Why it worked: 

A few weekends produced a few hundred dollars. 

Not meaningful to an adult, but Sajan was able to buy stuff he wanted.

Arbitrage: Variety fatigue and logistics 

Parents buy snacks in bulk because it’s efficient. Kids hate it because the selection gets boring after a few weeks. 

The result?  Pantries fill with half-eaten favorites. Parents either overspend trying to create variety or give up entirely. 

That’s why I propose a kid-run snack restoring services. 

Here’s how it works: 

You can even take it up a notch by offering dietary tiers.

Adults won’t build it, but kids will happily run it.

Arbitrage: Neglect and aggregation 

Lost-and-found bins at schools, gyms, churches, and community centers are full of value — but no owner.

Adults ignore them because no one owns the problem; the upside per item is low; and the process of sorting through everything is just annoying. 

Aggregated, though, it adds up. 

One sweatshirt isn’t worth much, neither is a water bottle or phone charger. But fifty forgotten items absolutely are. 

For kids, they could partner with a school or gym to manage the lost-and-found monthly. They will sort the items into three categories:

Proceeds will then be split between the organization and the kid. 

More than about nurturing a kid’s entrepreneurial spirit, kid arbitrage is also about recognizing something more important: they’re already operating with advantages adults no longer have. 

And if we’re paying attention, there’s a lot we can learn from that too.

This is the classic one-page strategy slide.

You’ve seen it, you know it – and you probably love it, for a good reason.

Strategic Plan-on-a-Page pulls the vision, strategic objectives, key levers, and initiatives into one place.

Because when everything lives on one page, teams can see what matters and start executing.

It takes seven times for something to really stick, so show this page on repeat – put it in exec meetings, team reviews, and references.

Let’s picture a fractional CRO stepping into a mid-market B2B company. 

Sales was discounting heavily to hit quota.  

Product was building features for one-off customer requests.  

Marketing was targeting every possible buyer instead of a clear target. 

Instead of starting with a brand-new roadmap, she used a Strategic Plan-on-Page first – highlighting clear priorities and explicit tradeoffs. 

With one shared plan, sales stopped chasing the wrong deals, product reprioritized, and marketing narrowed its focus. 

The result? Pipeline quality improved within a quarter – and internal friction dropped. 

Not because people worked harder, but because they’re working from the same plan.
