Bootstrapping from $0 to $20MM: What It Really Took to Build woom USA


From Broken Dishwashers to $20MM: The Reality of Bootstrapping a Startup

This article is a deeper dive in response to a recent post I shared previously— where I talked about a conversation I had with a founder wrestling with the classic startup dilemma:

“Should I raise money now or wait?”

I get this question all the time. And it’s one I’ve lived firsthand.

In 2014, I launched woom bikes USA with a big vision and very little money.

No venture capital. No seed funding. Just a belief in the product, a commitment to sell direct-to-consumer, and a stubborn refusal to give away equity too early.

Over the next seven years, we grew from zero to $20MM in annual revenue, averaging 300% year-over-year growth in the early years and hitting a 1,666% 3-year growth rate from 2016 to 2019.

That’s the headline.

But behind the scenes? It was messy. It was stressful. And it took everything I had—financially, emotionally, and mentally.


Betting It All

To get the business off the ground, I:

  • Sold my condo
  • Emptied my retirement accounts
  • Used up all my savings
  • Maxed out multiple credit cards

I didn’t take a salary for years. I reinvested every dollar back into the business.

In 2017, our dishwasher broke — and I couldn’t afford to fix it. At the time, I was juggling two jobs, raising two young kids, and keeping the business alive with maxed-out credit cards and whatever cash flow I could scrape together. So, we did the dishes by hand for months.

That dishwasher became a symbol. Of sacrifice. Of grit. Of what it means to bet everything on your vision. I remember standing in the kitchen, sleeves rolled up, exhausted from a day of hustling for sales, trying to meet payroll, and making dinner — and thinking: “This is what all in looks like.”

And being all in means risk. It means putting your name, reputation, and relationships on the line. It means waking up at 3am wondering if you’ll make payroll — and still showing up the next day with clarity and drive.


Cash Flow Chaos

woom was a capital-intensive business. We had to pay 50% of production orders upfront and the remaining 50% when the containers shipped—months before the bikes would ever be available for sale.

On top of that, our business was:

  • 80% direct-to-consumer with the remaining 20% through Amazon Vendor Central
  • Highly seasonal, peaking in March/April and November/December
  • Built on long 6–8 month lead times
  • Operating with no pre-orders or B2B buffers

Forecasting demand and cash needs became a full-time job. And growth made it even harder—because scaling fast without external capital creates constant pressure.

One spring, we hit a sales spike that depleted our inventory almost overnight. I had to place new orders immediately, but didn’t have the capital lined up. That led to a frantic week of calls, spreadsheets, and gut decisions. That scramble taught me more than any MBA ever could.

How do you finance 300% YOY growth when your inventory takes 8 months to arrive? You get creative. Really creative.


How I Financed It

Over the years, I tapped into nearly every non-equity financing tool available:

  • Liquid assets – I used my personal savings, sold my home, and pulled from retirement
  • Credit cards – I maxed out 8 credit cards to keep the business alive
  • Revenue-Based Financing (RBF) – Shopify Capital and PayPal Working Capital gave me fast, flexible funding. These are repaid as a percentage of daily sales, which helped with seasonal variability.
  • Merchant loans – Used OnDeck and others (expensive but necessary)
  • AR factoring – Amazon Vendor Central allowed me to factor receivables
  • UPS cargo finance program – Financed up to 80% of product value during shipping (this program no longer exists, but it saved us)
  • Friends, family, and crowdfunding – In October 2016, I reached out for loans. One friend verbally committed to loaning me $10K — and I was counting on it. I was deep in a cash crunch, juggling inventory payments, rent, and payroll. Then, just a few weeks later, right after the presidential election, he pulled the plug. He told me, “Trump just got elected. There’s too much uncertainty.”

That moment stung. It reminded me that even well-meaning people can get scared — and that in the end, you have to rely on yourself. You can’t build your business on maybe-money. That experience lit another fire in me. I doubled down even harder after that.

I also tried crowdfunding loans. While it didn’t raise much, it opened my eyes to how many unconventional options exist if you’re willing to explore, pitch, and ask.

  • SBA Loan – In 2018, I partnered with the Small Business Development Center (SBDC) and spent months working through complex documentation, financial modeling, and rigorous vetting to secure a $2MM SBA financing package: $1.3MM in a long-term loan and a $700K revolving line of credit. It wasn’t quick, and it wasn’t easy — but it was a major turning point. This infusion gave us the breathing room to grow without constantly fighting the cash flow fire. The process tested my patience, diligence, and endurance — but in the end, it was worth every ounce of effort.
  • Math in my head on Thursday nights – Literally calculating if I could make payroll on Friday. That’s how tight it was.

This is what “bootstrapping” actually looks like. You burn the boats. You make it work.

And yet—none of these tools are without risk. You need strong financial discipline and risk management. It’s easy to overextend when you're focused on growth, but every financing decision needs to be weighed carefully. What’s the cost of capital? What’s the cash flow impact? What happens if the sales forecast misses?


Additional Financing Options Founders Should Know

The good news? There are more financing tools available today than ever before.

From revenue-based financing and inventory loans to credit lines and pre-order platforms — the range of non-dilutive and flexible capital sources keeps expanding. You don’t need to know them all, but you do need to be resourceful.

Founders today must evaluate their unique cash flow needs, business model, and growth stage — and get curious about what financing options might be a good fit. Not every tool is right for every founder. But the right tool, at the right moment, can make all the difference.

Stay creative. Ask questions. Talk to others. And don’t assume venture capital is your only path.


What I Learned

Looking back, here are the biggest takeaways:

1. Belief Is Your First Investor

If you don’t believe in your vision 100%, you’ll fold. This kind of journey requires unreasonable conviction. And when people doubt you (and they will), that belief becomes your compass.

2. Resilience > Resources

Plenty of businesses fail with funding. What keeps you alive is your ability to get back up, stay flexible, and keep going—especially when it’s uncomfortable.

3. Know Your Numbers (and Your Options)

Understand cash flow, lead times, and capital needs at a granular level. And know what tools are out there—from equity-free lending to unconventional programs.

4. Seasonality Is a Beast

If you’re building a D2C seasonal business, you must be exceptional at forecasting. There's no shortcut. Mistakes here cost you real money.

5. You Have to Be All In

When founders tell me they’re not ready to put real skin in the game, it’s a red flag. If you don’t treat your business like your life depends on it, you’re leaving too much on the table.

6. Use Financing Responsibly

Financing can help you grow—but it’s not free money. If you don’t have a strong grip on cash flow and repayment terms, it can sink you just as fast. Be aggressive, but smart.


Final Thoughts

Building woom bikes USA was one of the most intense and rewarding experiences of my life.

It taught me how to think strategically, act urgently, and build something from the ground up without a financial cushion.

So to the founder wondering, "Should I raise or wait?" — just know: there's no one right answer. But if you’re resourceful, resilient, and intentional, you can build something meaningful without giving up control too soon.

I’ve tried almost every financing option in the book. I’ve made mistakes, learned fast, and kept going. If you’re a founder navigating this kind of chaos—I see you. And I’m happy to talk if you want to connect.

You don’t need to raise millions to build something meaningful. But you do need to be all in.
