Why we built this
(and why it works)

I'm Marcel Santilli, CEO of GrowthX. This story starts at IBM, where I watched them burn through over a billion dollars annually on marketing that created zero lasting value.

Think about that number. A billion dollars. On ads that disappear the moment you stop paying. On content syndication that nobody reads. On renting attention instead of earning it.

I did the math. For what IBM spent on empty marketing, they could have literally bought every publication in every category they competed in.

That's when it hit me: What if companies became publishers instead of just advertisers?

I convinced IBM to let me test this theory. We built SecurityIntelligence.com and started publishing valuable content for security professionals.

The results in year one:

• $50 million in pipeline generated
• Less than $1 million invested
• Became the highest ROI channel for the entire business unit

But here's what mattered more than the numbers: we shifted from interrupting people to helping them. Instead of asking "How do I get you to click?" we asked "How do I become the best answer to your questions?"

At HP, I took this approach further. We built a contributor network of 1,000+ subject matter experts. Four managing editors. Teams of ghostwriters. A content machine cranking out 20 articles weekly.

The results:

• 1 million visitors monthly (all organic)
• 200,000 newsletter subscribers
• Biggest lead source for the business for over 10 years

The playbook was working. But it wasn't getting easier.

I kept building these content engines everywhere I went:

• HashiCorp: Helped grow from $6M to $100M ARR in 2 years
• ServiceTitan: Built content strategy for a company now worth billions
• Scale AI: Created Transform X conference featuring Sam Altman and Andrew Ng—10,000 attendees, $100M pipeline, budget under $100K

Each time, same process:

1. Hire editors
2. Build content strategy
3. Recruit subject matter experts
4. Systematically create high-quality content
5. Distribute and convert attention into revenue

The problem: It never got easier. Every new company meant rebuilding the entire machine from scratch.

At Deepgram, something changed. Instead of just executing the same manual processes, I spent thousands of hours distilling everything I knew into AI workflows.

How do you research audiences? Build a workflow.

How do you identify content opportunities? Build a workflow.

How do you plan, research, draft, optimize, and distribute? Build workflows for all of it.

I kept expert editors in the loop for strategy, QA, and brand alignment. But the AI handled the heavy lifting.

The results were shocking:

• 24x traffic growth
• 4x revenue increase
• Content machine that actually got smarter over time

I started teaching workshops on building these AI workflows. 170 people paid for full-day sessions. But here's what I learned:

People didn't want to build workflows. They wanted the outcomes.

They needed help adapting the workflows to their business. They needed experts in the loop to guide strategy and ensure quality. They wanted the system, not the instructions.

That's how GrowthX was born.

We went from zero to >$11M run rate in under a year. All organic growth. No ads. No traditional marketing.

How? The same way we help our clients: by consistently delivering value and earning trust.

Current clients include:

Most companies are still stuck where I was 15 years ago. Choosing between expensive agencies that move slowly or trying to build content engines with internal teams that don't have the expertise.

We've solved a problem I've been working on my entire career: How do you create a content engine that actually compounds value over time?

The answer isn't just AI. It's not just human expertise either. It's the combination—AI workflows that think like experts, guided by humans who've built these engines before.

That's what we do. That's why it works.
