The advice nobody gives you when you start a service business

When I launched Unosquare in 2009, I did what a lot of first-time founders do — I listened to bankers. They told me a line of credit was smart. That leverage was how real businesses scaled. That I'd need access to cash to grow fast. So I signed up for a small business line of credit and promptly regretted it.

The lender took payments directly out of our checking account. We had no flexibility. The interest was higher than I expected. And I'd personally guaranteed the loan, which meant if anything went sideways, it wasn't just the business on the line — it was me. That experience shaped everything that came after.

Why service businesses don't need debt

Here's the thing about a service company that most people don't fully grasp: your product is time and expertise. You don't need a factory. You don't need inventory. You don't need to hire a hundred engineers before you make a dollar. You invoice a client, you get paid, you hire. The cash cycle is short — if you manage your margins properly.

Companies like Amazon needed to raise billions before they ever made a profit because they were building physical infrastructure at massive scale. That's not what a service business is. If you're burning cash before you have revenue in a services model, something is structurally wrong — and debt won't fix it, it'll just delay the reckoning.

"Bigger is not necessarily better. Debt-free and profitable is better. I'd rather own 100% of something healthy than a shrinking slice of something that's always chasing its next round."

The rules we built Unosquare on

We grew from 3 employees to nearly 400 over 8.5 years without a single dollar of outside debt. Here's how we thought about it:

Gross margin is the only number that matters. Not revenue. Not headcount. Not the size of the deals we were chasing. Gross margin tells you whether your business is actually healthy. We set a minimum threshold — 40% — and we walked away from clients who couldn't get us there. It felt painful in the early days. It was the right call every single time.

We set rules for how we spent gross margin — and we never broke them. No more than 30% on overhead. Profit distributions only happened when we hit three thresholds simultaneously: 40% year-over-year growth, 40% gross margin, and 10% net profit margin. If we missed any one of them, the money stayed in the business. Full stop.

What this model actually buys you

The thing nobody tells you about staying debt-free is what it does to your decision-making. When you don't have investors to answer to or loan covenants to meet, you can make the right call for the long term — even when it's uncomfortable in the short term. You can fire a bad client. You can pass on a big deal with thin margins. You can invest in your people instead of servicing debt.

We built a company we were proud of, on our terms, without ever giving away control. That's the real payoff. Not the revenue number — the freedom.
