There are some podcast conversations where you walk in expecting to talk about one thing and quickly realize there is a much bigger conversation underneath it.<\/span><\/p>

That was the case when I sat down with\u00a0Gary Guseinov, CEO of RealDefense, and Sean Whiteley, President of RealDefense<\/b>, for an episode of\u00a0The Casey Zeman Show<\/i>.<\/p>

On paper, there was plenty to talk about. RealDefense has become a significant player in consumer cybersecurity, privacy and device optimization. The company says it has completed six strategic acquisitions, serves more than three million customers, has access to an addressable market of roughly one billion users through its ecosystem, and currently generates approximately\u00a0$150 million per year in annual partner revenue<\/b>.\u00a0(RealDefense)<\/a><\/p>

Deloitte ranked RealDefense\u00a0#406 on its 2024 Technology Fast 500<\/b>, after the company posted\u00a0267% revenue growth from 2020 through 2023<\/b>. (Deloitte<\/a>)<\/p>

And the growth hasn\u2019t gone unnoticed since then. In 2026, RealDefense announced that it had been ranked\u00a0#129 on the Inc. Regionals: Pacific list<\/b>\u00a0of fast-growing private companies. (RealDefense<\/a>)<\/p>

But before we got into any of that, there was a much more personal reason I was excited about the conversation.<\/p>

A New Baby, an Old Webinar Company and a Very Small World<\/h5>

I\u2019d recently had the chance to spend some time with Gary at his home. And while Gary has spent decades building companies, making acquisitions and allocating capital, at the time we recorded the episode he had recently taken on a very different title:<\/p>

Dad. <\/b>Gary and his family had welcomed a baby girl, and it was fun seeing him in this completely new chapter of his life. We got to celebrate that for a moment before diving into EBITDA, customer acquisition costs, and artificial intelligence.<\/p>

I think those things matter. It\u2019s easy to look at successful founders through the lens of businesses, exits, revenue numbers, and LinkedIn profiles. But we\u2019re all moving through different seasons at the same time. Someone can be thinking about a multimillion-dollar acquisition in one conversation and thinking about diapers and sleep schedules in the next.<\/p>

There was another coincidence that made the conversation particularly interesting for me.<\/p>

Gary and Sean had previously been involved with\u00a0Business Hangouts<\/b>\u2014not Google Hangouts itself, but a webinar and streaming platform from the Google Hangouts era.<\/p>

Gary had acquired the business, Sean became involved, and they used that relatively small acquisition as one of the places where they began developing the acquisition and operating playbook they would use later. Sean estimated during our conversation that they ultimately created roughly four times the value from that investment before moving on to additional acquisitions.<\/p>

Naturally, the webinar connection caught my attention. I\u2019ve spent the better part of my career in this industry through EasyWebinar. Then the world got even smaller.<\/p>

As we talked, we realized that\u00a0Gary and I had both worked with the same person at different points in our careers<\/b>. Not at the same time. Not even in the same era.<\/p>

Someone who had worked in their world years earlier eventually ended up working with me at EasyWebinar. There was something funny about that.<\/p>

Different companies. Different years. Different paths. And somehow webinars had connected all of us. But there\u2019s also a deeper reason that connection interested me.<\/p>

Gary and Sean understand something about webinars that many people who have never operated in the space don\u2019t immediately appreciate. A great webinar isn\u2019t simply a digital presentation.<\/p>

It is a\u00a0belief-building environment<\/b>.<\/p>

I\u2019ve sometimes described this as\u00a0story indoctrination<\/i>\u2014not in the manipulative sense of the word, but in the sense that you are giving someone enough context, education and narrative to begin seeing a problem through a different lens.<\/p>

A strong webinar takes someone through a progression:<\/p>

Here is the problem.<\/b>\u2028<\/b>Here is why the problem exists.<\/b>\u2028<\/b>Here is what you may have misunderstood.<\/b>\u2028<\/b>Here is what is possible.<\/b>\u2028<\/b>Here is a different mechanism for solving it.<\/b>\u2028<\/b>Here is the evidence.<\/b>\u2028<\/b>And now, here is the decision in front of you.<\/b><\/p>

That process is increasingly important in a world where information itself is becoming commoditized.<\/p>

People don\u2019t need another 15-second piece of content telling them what to think. They need context. They need someone to connect the dots. They need enough time with an idea to actually understand it. And interestingly, that same concept\u2014understanding the story underneath the numbers\u2014kept resurfacing throughout my conversation with Gary and Sean.<\/p>

These Aren\u2019t Theoretical Operators<\/h5>

Before getting into the lessons, it\u2019s worth understanding the experience sitting on the other side of the conversation. Gary\u2019s history in cybersecurity goes back more than two decades.<\/p>

He originally founded the business that became\u00a0CyberDefender<\/b>\u00a0in the early 2000s. According to a case study from RealDefense financing partner Sunflower Bank, CyberDefender went from essentially zero to approximately\u00a0$70 million in revenue in roughly five years<\/b>\u00a0before Gary ultimately took the company public on Nasdaq. (Sunflower Bank<\/a>)<\/p>

Years later, after the company had changed hands and declined, Gary came back. In 2017, he assembled a group that included Sean, Corbel Capital Partners and Broadstream Capital Partners and\u00a0bought the business back<\/b>, rebuilt it as RealDefense and returned it to profitable growth. (Sunflower Bank<\/a>)<\/p>

Since then, RealDefense has used acquisitions as an important piece of its model, adding businesses and brands including USTechSupport, iolo, STOPzilla, SUPERAntiSpyware and Support.com. (RealDefense<\/a>)<\/p>

In a March 2026 interview with SaaS entrepreneur and interviewer Nathan Latka, Gary said RealDefense finished 2025 with roughly\u00a0$60\u201370 million in top-line revenue and $20\u201325 million in EBITDA<\/b>, with approximately 300 people supporting the business. Those figures were self-reported by Gary in that interview, but they provide a useful sense of the scale at which he and Sean are now operating. (Latka<\/a>)<\/p>

Sean brings a different but equally impressive operating r\u00e9sum\u00e9. Before RealDefense, he served as COO of\u00a0Cargomatic<\/b>\u00a0and\u00a0TigerText<\/b>, Vice President of Operations at News Corp\u2019s\u00a0Slingshot Labs<\/b>, CEO and co-founder of\u00a0RealtyTracker<\/b>, which was acquired by Guthy-Renker, and Vice President of Operations at\u00a0Xdrive Technologies<\/b>, which was acquired by AOL. (Marine Electronics<\/a>)<\/p>

So when Gary and Sean talk about moving from startup mode into mature operating discipline, they\u2019re not describing something they read in a management book. They\u2019ve lived it repeatedly. And several ideas from our conversation stood out.<\/p>

1. Growth Doesn\u2019t Eliminate Risk. It Multiplies It.<\/h5>

Founders tend to imagine scale as the point where the business finally gets easier. Gary sees almost the opposite.<\/p>

As a business grows, different categories of risk begin compounding. Infrastructure risk. Fraud risk. Competitive risk. Pricing risk. Fulfillment risk. Marketing risk. Organizational risk.<\/p>

There isn\u2019t some magical revenue number where those disappear. In fact, as Gary put it,\u00a0the bigger you become, the more relevant those risks become<\/b>.<\/p>

The job changes from simply reacting to problems to conditioning the organization to recognize what might be around the corner. That is a very different type of entrepreneurship.<\/p>

At the beginning, founders often win because they are willing to move faster than everyone else. At scale, you also have to learn how to\u00a0see farther than everyone else<\/b>.<\/p>

2. Eventually, CAC Comes for Everyone<\/h5>

Gary then moved into one of the most important pieces of business math in the entire episode.<\/p>

Customer acquisition costs tend to rise as you scale. <\/b>Your first customer is not necessarily as expensive to acquire as your 100,000th customer.<\/p>

Early in a market, you may capture people with the greatest urgency, strongest product awareness, or highest willingness to act.<\/p>

As you expand, you begin reaching customers who require more convincing. Meanwhile, competitors are entering auctions for the same clicks, impressions and audiences.<\/p>

That puts upward pressure on CAC. And that means your business model has to be designed to survive it.<\/p>

Gary\u2019s argument was that companies need\u00a0elasticity in their monetization<\/b>.<\/p>

If your entire business depends on selling one $29 product, but eventually it costs $70, $90 or $120 to acquire a new customer, the math will begin working against you. Instead, the strongest businesses create multiple ways to increase the economic value of a customer.<\/p>

Maybe there is a $29 entry product. Then a $50 product. Then $100. $500. $1,000. Or perhaps recurring revenue, higher-tier plans, services, cross-sells and additional solutions increase lifetime value over time.<\/p>

The specific prices aren\u2019t the point.The spread is. <\/b>Your monetization has to create enough room for customer acquisition costs to increase without destroying the economics of the business.<\/p>

This is especially relevant to anyone in the EasyWebinar world. We can become obsessed with metrics such as: cost per webinar registration, show-up rate, conversion rate, cost per booked call, and front-end ROAS. Those metrics absolutely matter.<\/p>

But none of them independently tell you whether you have a great business.<\/p>

The larger question is:<\/p>

How much economic value can you responsibly create from every customer you acquire?<\/b><\/p>

Because in most competitive markets, one of the strongest advantages belongs to the company that can afford to spend more to acquire the right customer\u2014and still remain profitable.<\/p>

3. The Bigger the Spend, the Deeper the Data Has to Go<\/h5>

Sean made a related point that I thought was particularly important.<\/p>

In a small company, your analytics can sometimes be relatively crude.<\/p>

You spend $10,000. Customers come in. You look at the resulting revenue. The math works. Great. But increase that spend dramatically and suddenly the question isn\u2019t simply:<\/p>

Did the campaign work?<\/b><\/p>

You have to know:<\/p>
