He Started Selling Sneakers From His Bedroom. By 24, His Company Was Moving $40 Million a Year.

Legacy Ledger Series: Case in Point · Built From Scratch · Build It

A teenager buying and reselling sneakers sounds like a simple side hustle. A few hundred bucks here. A rare pair of Jordans there. Enough for gas money and a car payment.

Yeah, Oscar Rachmansky blew straight past that ceiling…

What started as sneaker reselling in high school became OS Group, a business to business footwear and streetwear company that generated roughly $40 million in sales revenue in 2025, according to financial documents reviewed by Business Insider. Rachmansky was 24 when that number hit the record books.

And personally, I think the sneakers aren't even the interesting part. The interesting part is what he saw that everyone else walked right past.

Before you continue reading, if you’re interested in becoming an entrepreneur, think about how you could take this business model and use it as inspiration for your own ideas.

The sneaker resale game is pretty simple on the surface: buy something people are desperate for, get it before everyone else, flip it for more. A $200 sneaker becomes $300, $500, and sometimes thousands!

That gold rush spawned an entire underground economy of resellers. Rachmansky was one of them, grinding through high school, building up roughly $30,000 from the hustle by the time he hit college, respect.

Most people staring at that pile of cash ask one question, “How do I sell more shoes?”

Rachmansky asked a far more dangerous one, “Why is this entire system so broken?”

Independent sneaker stores had a problem nobody was solving. Unlike the giants with direct pipelines to major brands, small shops were stuck scrambling trying to piece together inventory from scattered sellers, marketplaces, and personal connections. Fragmented. Inefficient. Yet oh so Ripe!

Rachmansky realized he didn't have to fight thousands of resellers for scraps. He could become the company supplying every one of them.

The shift was huge:

Buy shoe → find customer → sell shoe became Source inventory at scale → supply retailers → repeat.

OS Group launched in 2019 as a B2B wholesaler of branded footwear and streetwear. He wasn't playing the market anymore. He was building the plumbing underneath it.

Here's where the success story is supposed to slow down but this one didn't get to.

COVID hit. The resale market froze solid.

Rachmansky has said flatly that there was a stretch where the business made no money at all, and he seriously considered walking away and staying in school.

Sit with that for a second. You've bet everything on an opportunity. You've started building it. And then the entire world shuts down and your brilliant idea looks like a catastrophic mistake.

This is the part every highlight reel conveniently cuts. We see the $40 million headline. We never see the moment he thought: maybe I got this completely wrong.

In business, this is a common occurance and I’ll say from experience…it can hurt. That’s why you must have heart and determination to see things through until the end. For Rachmansky, his end had yet to arrive.

Supply chains buckled. Production tightened. Demand didn't budge an inch. Prices on Nike, Jordan, and Adidas products surged to multiples of retail.

Rachmansky didn't hedge. He went all in, leaving McGill University and pouring the roughly $30,000 from his sneaker hustle straight into the company.

No venture capital. No billion dollar valuation headline. Just money he'd already earned, funding the bigger bet. And that distinction matters because the sneaker flipping was never the destination, it was the fuel. Let that marinate!

This might be the best detail in the entire story.

OS Group didn't start in some sleek glass headquarters. One early employee recalled that their first warehouse didn't even have real offices so the team built makeshift cubicles out of Nike Air Force 1 boxes.

Just picture the before and after for a second.

Today: millions in revenue, thousands of products shipping monthly, employees, warehouses, real technology.

Day one: cardboard shoe boxes standing in for office walls.

Businesses almost always look ridiculous before they look inevitable.

By 2025, OS Group had grown to about 30 employees, distributing roughly 25,000 products a month out of a New Jersey facility, with Business Insider putting 2025 sales revenue at approximately $40 million.

But notice the word revenue, not profit. A $40 million business does not mean Rachmansky pocketed $40 million. Wholesale operations move enormous volume on comparatively thin margins. That nuance gets erased by half the entrepreneurship content on the internet. It shouldn't be. It actually makes the real lesson sharper. This was never about finding one magical pair of sneakers, it was about engineering a system that could move product at scale, over and over.

Eventually the pandemic sneaker frenzy cooled. Sneakers that once commanded massive resale premiums stopped commanding much of anything.

That should have gutted a company built entirely on "sneakers go up." But OS Group had already positioned itself around something bigger, the movement of inventory between businesses, period.

In 2026, OS Group announced a B2B commerce platform giving retailers centralized access to secondary market footwear and streetwear inventory. Another rung up the ladder:

Reseller → wholesaler → infrastructure.

Every step moves further from trading your own time for one transaction at a time.

You don't need to start a sneaker company. You don't need to drop out of college. And please, do not read one success story and conclude education is worthless. That's the wrong lesson completely.

Here's the right one:

1. Small money can be seed capital.
Your first business doesn't have to make you rich. Sometimes its only job is generating the skills, relationships, and capital for the next opportunity. Rachmansky's sneaker money didn't make him, it funded what did. Your first $5,000 might not change your life. What you do with it might.

If you're building toward a business of your own, the question isn't only how to earn the capital. It's where that capital sits while you build. That's the conversation we have at Legacy Vault Financial. I go deeper in my book, Called to Legacy, Assigned to Prosper.

2. Look for the problem behind the obvious problem.
Thousands of people saw valuable sneakers. Rachmansky saw retailers drowning in a broken supply chain. Don't just ask "how do I sell this?" Ask: "What do all the people selling this actually need?" That question turns boring businesses into massive ones.

3. Revenue follows systems, not transactions.
Selling one shoe is a sale. Moving 25,000 items a month is an operation people, suppliers, warehousing, technology, process. That's the line between a hustle and an enterprise.

4. Your first idea doesn't have to be your last business.
Reseller became wholesaler became infrastructure. Sometimes you don't find your real business by planning it perfectly, you find it by starting something small and following where the opportunity actually leads. Nothing happens if you don’t start.

It's tempting to flatten this into young guy sells shoes, gets rich. That's the headline but it's not the story.

The real story is a teenager who entered a market as a participant, learned exactly how the machinery worked, spotted the inefficiency everyone else ignored, stacked capital, and climbed higher up the value chain, one rung at a time.

That principle has nothing to do with sneakers. Some people sell products. Some people supply the sellers. Some people build the platform everyone else ends up depending on. The farther down that chain you look, the less glamorous, and the more valuable, the opportunity gets.

A pair of sneakers got Oscar Rachmansky started. The system behind them is what built the business.
