Start a $15M Solo Business: Justin Welsh’s Playbook

Key Takeaways

• Building a solo operation can reach $15 million in revenue by focusing on high-margin digital products rather than heavy physical overhead.
• Keeping your team size at one or two people eliminates the high cost of employee benefits and payroll taxes which often drain small business cash flow.
• You must register for an EIN (Employer Identification Number) through the IRS even if you have no employees to keep your personal and business finances separate.
• Solopreneurs should use a dedicated business bank account like Mercury to track deductible expenses without mixing them with personal spending.

Justin Welsh recently sparked a massive conversation about the math of staying small. In a recent post, Welsh mentioned he built his one-person business to $15 million. This number sounds like a tech startup figure, but the mechanism is actually very grounded in the same basics every HVAC business or solo bookkeeper uses. The core idea is that you don't need a 20-person team to hit massive profit levels. Most owners think they have to hire to grow. Welsh argues the opposite. By staying solo, you avoid the complexity of managing people and the huge tax burden that comes with a growing payroll. If you're just starting out, this means you can focus entirely on your service or product rather than becoming a full-time manager.

The Real Cost of Adding That First Employee

Many new owners rush to hire because they feel overwhelmed.

But adding just one W-2 employee changes your entire legal and financial profile. You aren't just paying their salary. You're paying half of their Social Security and Medicare taxes, plus federal and state unemployment insurance. S. Htm), benefits and taxes can account for roughly 30 percent of an employee's total cost. If you hire someone for $50,000, they actually cost you closer to $65,000. Welsh's model skips this entirely by using software or automated systems to do the work a junior assistant would normally handle.

Practical Steps to Stay Solo Longer

1. Use automated scheduling tools to stop the back-and-forth email chains with customers.
2. Set up a professional business entity to protect your personal assets. You can find out how to start this through the U.S. Small Business Administration.
3. Outsource specific tasks to freelancers (1099 contractors) rather than hiring full-time staff until your profit is consistent.
4. Keep your fixed costs like rent and software subscriptions below 20 percent of your monthly revenue.

Managing Your Cash Flow Alone

1. Open a business checking account immediately. Don't buy groceries with the same card you use for web hosting.
2. Set aside 30 percent of every invoice for taxes in a separate savings account.
3. Use a simple bookkeeping tool to track every expense so you don't miss deductions at the end of the year.

Every dollar you don't spend on a manager's salary is a dollar that stays in your pocket or goes back into marketing.

If you want to follow this path, you need to be disciplined about your time. A solo operator in Austin or a plumber in Georgia both face the same ceiling: there are only so many hours in a day. Welsh breaks that ceiling by selling products that don't require his physical presence, like digital guides or subscriptions. For a service business, this might look like selling a 'maintenance manual' to clients alongside your repair services. The goal is to make money while you aren't actively working. This protects you from the fear of running out of cash if you get sick or take a week off. Focus on building a system, not just working a job.
