Episode #82: Marc Gaffan – CEO Ionix

In this episode, we speak with Marc Gaffan, a three-time startup operator, investor, and current CEO of Ionix, which just raised a $42M Series A.  

Marc has spent the past two decades in cybersecurity. In 2008, he co-founded Incapsula, later acquired by Imperva, and since then, he’s led, invested in, and mentored multiple cyber startups. 

But if there’s one thing he’s learned?  

No two startup rodeos are the same.    

“Every startup has its own dynamics, its own challenges. There’s no playbook. You can’t ask ChatGPT to write the recipe for doing a startup. When they do that, then I think we’ll be done.”    

In this conversation, we dive into what it really takes to build, lead, and survive in the startup world:  

The startup rollercoaster never stops – but you get better at holding on.    

Marc explains that experience doesn’t mean things get easier.  “It’s not that you come up with better answers to problems, but you recognize the common themes. You know it won’t be a smooth sail, and over time, it doesn’t shake you as much as it used to.”    

Mental and decision-making resilience – the two muscles every founder needs.    

It’s one thing to push through a tough moment. It’s another to do it over and over again without burning out.   “How do you keep your mental resilience going? It’s a tough roller coaster.”    

The harsh reality of being an investor vs. an operator.    

We talk about the limits of investor influence – and why control ultimately belongs to those in the trenches. “The only thing a board can really do operationally is fire the CEO. If you really want to have an impact, you can’t be on the sidelines. You have to be in the field.”    

Why fixing weaknesses is a waste of time – and how to leverage strengths instead.    

Too many people spend their careers trying to be something they’re not. Marc argues for a different approach:   “If you’re not gifted at math, forcing yourself to be really good at it won’t work. Instead, invest heavily in what you are good at. That’s where you’ll find fulfillment and confidence.”    

The importance of celebrating wins – even when the work isn’t done.    

It’s easy to focus on the unfinished 15%. The problems. The gaps. The “not there yet.” But Marc reminds us:   “You need to stop and appreciate how far you’ve come. Your gut instinct sharpens over time – not because of luck, but because experience refines it.”    

The innocent bliss of starting something new.    

“As a CEO, you don’t really know what you’re getting into. And in some ways, that’s good. If you truly understood the odds, you might never take the leap. But the journey matters. And who you take it with matters even more.”    

Marc has built companies. He’s struggled. He’s succeeded. He’s learned. And now, he’s here to share his perspective.  

If you’ve ever tried to build something from the ground up – this episode is for you.
