If You Can't Answer These 5 Questions, You're Not Doing Growth

Last month, I asked a founder a simple question: "What's your CAC?"

He looked at me like I'd asked him to explain quantum physics. "What's that?"

Customer Acquisition Cost. The single most important number in your business. And he had no idea.

Here's the thing: this wasn't a first-time founder running a side project. This was a seven-figure company with a sales team, a marketing budget, and ambitious growth targets. And they couldn't tell me what it cost to acquire a single customer.

I wish I could say this was unusual. It's not.

In every engagement I've had over the past eight years—from early-stage startups to companies competing with Airbnb—I ask the same five questions in the first meeting. 90% of clients can't answer a single one.

That's not a criticism. It's a diagnosis.

No estamos midiendo. We're not measuring. And if you're not measuring, you're not doing Growth. You're guessing. You're burning money. You're making decisions based on hope instead of data.

Let me walk you through the five questions. If you can't answer them, keep reading—because this is exactly where we need to start.

The 5 Questions Every Business Must Answer

1. What's your Cost Per Lead?

What it measures: How much you spend to generate someone interested in your product.

A lead is anyone who raises their hand—fills out a form, downloads a resource, requests information. Your Cost Per Lead (CPL) tells you how efficiently your marketing is generating that initial interest.

Why it matters:

If you're spending $10,000/month on ads and generating 100 leads, your CPL is $100. Simple math. But here's where it gets interesting: that $100 lead might be worthless if they're not qualified.

I've seen companies celebrate low CPL numbers while their sales team drowns in garbage leads. "We're getting leads for $15!" Yeah—and converting 0.5% of them. Your "cheap" leads are costing you a fortune in wasted sales time.

The consequence of not knowing:

You can't optimize your top of funnel. You can't compare channels. You're blind to whether your campaigns are working or burning cash.

What "good" looks like:

This varies wildly by industry. B2B SaaS? $50-150 CPL might be excellent. High-ticket services? $200-500 could be sustainable. The number matters less than knowing it and tracking it over time.

2. What's your Cost Per SQL?

What it measures: How much you spend to generate a Sales Qualified Lead—someone your sales team has actually spoken with and confirmed as a real opportunity.

This is where the magic happens. Or doesn't.

Why it matters:

The gap between CPL and Cost Per SQL (CPSQL) reveals the quality of your leads. If you're paying $100 per lead but your CPSQL is $1,000, nine out of ten leads are garbage. That's a targeting problem, a qualification problem, or a messaging problem. Probably all three.

In one engagement, a client was spending $40,000/month on Google Ads. Their CPL looked great—around $80. But when we dug into the data, their CPSQL was $1,600. For every 20 leads coming in, only one was actually qualified to buy.

We fixed the targeting, added qualification filters, and within 60 days their CPSQL dropped to $400. Same budget. Four times more real opportunities.

The consequence of not knowing:

You don't know if you have a marketing problem or a qualification problem. You're wasting sales capacity on unqualified leads. Your team gets burned out chasing ghosts.

What "good" looks like:

Your CPSQL should ideally be 2-4x your CPL. If it's 10x+ your CPL, you have a serious qualification gap that needs immediate attention.

3. What's your Call Acceptance Rate?

What it measures: Of the leads you generate, how many actually pick up the phone or show up to meetings?

This is the metric nobody tracks—and it's killing your pipeline.

Why it matters:

You could have perfect targeting and generate beautiful SQLs, but if they don't answer when your sales team calls, none of it matters.

I've worked with companies where the Call Acceptance Rate was below 20%. Four out of five leads never had a real conversation with sales. They filled out a form, maybe got an email, then vanished.

The fix usually isn't complicated. Speed to lead. If you wait 24 hours to call a new lead, your acceptance rate drops by 80%. If you call within 5 minutes? It quadruples.

The consequence of not knowing:

You blame marketing for bad leads when the problem is slow follow-up. You miss the easiest win in your entire funnel. You hire more salespeople when you should be fixing your response time.

What "good" looks like:

60%+ for inbound leads if you're responding quickly. Below 40%? You have a process problem, not a lead quality problem.

4. What's your Conversion Rate?

What it measures: Of the people who talk to sales, how many become customers?

This is where Growth becomes Growth. Everything upstream is just preparation for this moment.

Why it matters:

Your conversion rate tells you how effective your sales process is. But more importantly, it tells you where you're losing deals.

Are people dropping after the first call? Your qualification might be off—or your pitch isn't landing. Dropping after proposals? Pricing problem or value communication problem. Getting ghosted after sending contracts? Friction in your close process.

Each stage has a conversion rate. If you're not tracking them individually, you're flying blind in the most expensive part of your funnel.

The consequence of not knowing:

You can't coach your sales team effectively. You can't identify bottlenecks. You throw money at marketing when the real problem is a broken close process.

What "good" looks like:

B2B services: 20-40% from SQL to close is solid. E-commerce: 2-5% site-wide. SaaS free-to-paid: 3-10%. But again—the specific number matters less than knowing it and improving it systematically.

5. What's your CAC (Customer Acquisition Cost)?

What it measures: The full cost of acquiring a paying customer. Marketing spend + sales costs + overhead, divided by customers acquired.

This is the number. The one that tells you whether your business model works.

Why it matters:

CAC is the synthesis of everything above. It combines your marketing efficiency (CPL), your qualification quality (CPSQL), your reachability (Call Acceptance), and your sales effectiveness (Conversion Rate) into a single number that tells you: is this sustainable?

When I joined a property management company competing with Airbnb, their CAC was around $1,500. Sustainable? Barely. Room to scale? None.

By implementing proper funnel tracking, optimizing targeting, and fixing their follow-up process, we got CAC down to $700. Same product. Same market. Nearly half the cost to acquire each customer. That's the difference between a business that's surviving and one that's scaling.

The consequence of not knowing:

You don't know if you're building a sustainable business or slowly bleeding to death. You can't set budgets intelligently. You can't plan for growth because you don't know what growth costs.

What "good" looks like:

Your CAC should be recoverable within 3-12 months of customer revenue, depending on your model. If your CAC is $500 and your monthly revenue per customer is $100, you're healthy at 5-month payback. If CAC is $5,000 and monthly revenue is $50? You need to fix something fast.

Why This Isn't Optional

Growth Marketing without metrics is just... marketing.

The word "Growth" implies measurement. It implies optimization. It implies making decisions based on data, not gut feelings or hope or "well, it feels like we're doing better."

When I tell clients they're not doing Growth, I don't mean they're bad at their jobs. I mean they're operating without the basic instrumentation required to actually grow.

Imagine flying a plane without an altimeter, airspeed indicator, or fuel gauge. You might take off okay. You might even reach cruising altitude. But eventually, something goes wrong—and you won't know until it's too late.

That's what business looks like without these five numbers.

The cost compounds. Every decision made without data is a guess. Some guesses are right. Most aren't. And over months and years, those wrong guesses accumulate into millions of dollars in wasted spend, missed opportunities, and frustrating stagnation.

How to Set Up Visibility Fast

Here's the good news: this doesn't require a two-month analytics project or a $50,000 data warehouse implementation.

You can get basic visibility in 48 hours. Here's how I approach it:

Day 1: Map Your Funnel

Write down every stage from first touch to paying customer. Be specific:

Assign a number to each stage. Even if the number is a guess. "About 50 leads/month, maybe 10 get calls, 3 close." That's your starting point.

Day 1: Connect Your Tools

You don't need enterprise software. A simple stack works:

HubSpot free tier. Pipedrive. Even Notion with the right setup. The tool doesn't matter. The tracking does.

Day 2: Build the Dashboard

Five numbers. One place. Updated weekly.

That's it. You don't need seventeen dashboards with real-time updating and AI-powered insights. You need five numbers you look at every week and try to improve.

The Minimum Viable Dashboard works. Don't overcomplicate it. Start with these five numbers, get them accurate, and watch how quickly your decision-making improves.

If You Can't Answer These Questions, You're Not Alone

90% of the companies I work with start here. Successful companies. Smart founders. Experienced teams.

They're not failing because they're incompetent. They're struggling because nobody set up the instrumentation.

This is exactly what I fix.

Before we talk about scaling campaigns, optimizing creative, or expanding to new channels—we answer these five questions. We build visibility. We stop guessing.

Because Growth Marketing without metrics isn't Growth Marketing at all. It's expensive hope.

And hope is not a strategy.
