<\/p>\n

At just 46 years old, Dino Mavrookas\u2019 career already looks more expansive than most, spanning three distinct roles: Navy SEAL, private-equity investor, and now cofounder and CEO of $9.25 defense-tech startup Saronic\u2014proof that your first career doesn\u2019t have to be your last.<\/p>\n

\n

His latest career pivot came just four years ago, when Mavrookas was a senior associate at Austin-based private equity firm Vista Equity Partners. However, after half a decade in finance\u2014likely bringing in a six-figure salary\u2014Mavrookas began to question whether he wanted to spend the rest of his career on the same path.<\/p>\n

\u201cAfter five years, I started to look around and say, is this what I want to do for the next 20 or 30 years of my life? Like, I learned a ton about investing. I learned a ton about operating companies, but is this what I wanted my career to be? And the answer was no,\u201d Mavrookas said in a recent interview on the Sourcery<\/em> podcast.<\/p>\n

\u201cI walked into the living room one night and I told my wife that I had to quit my job.\u201d<\/p>\n

Mavrookas knew he wanted to start a defense-tech company, but he didn\u2019t yet know what the business would be. What he did know was that he needed to create the time and space to figure it out.<\/p>\n

\u201cI just knew that I had to go and focus my energy there, and I wasn\u2019t going to come up with Saronic, or at that point whatever the idea was, if I was working 80 to 100 hours a week at a finance firm,\u201d he said.<\/p>\n

That leap has proved to be a lucrative one.\u00a0<\/p>\n

Mavrookas co-founded Saronic in 2022, focusing on the development of autonomous maritime vehicles. The Austin-based firm has become one of the fastest-growing in defense tech, with a $9.25 billion valuation and a workforce of more than 1,000 employees. It is also expanding aggressively: Saronic currently has more than 200 open roles, and earlier this year announced plans for \u201cPort Alpha,\u201d a next-generation shipyard in Brownsville, Texas, that the company says will create 10,000 jobs and generate billions of dollars in investment.<\/p>\n

How being a Navy SEAL prepared Mavrookas for entrepreneurship\u2014and the C-suite<\/h2>\n

For Gen Z workers who feel intensive pressure to map out their entire careers\u2014and pick a trajectory that\u2019s simultaneously AI-proof, lucrative, and also interesting\u2014Mavrookas\u2019 path offers a different lesson: You don\u2019t necessarily need to know exactly where you\u2019re going before making a change.\u00a0<\/p>\n

In his case, each experience built on the one before it, eventually giving him a combination of technical, military, and business expertise that he could bring to the C-suite.\u00a0<\/p>\n

Before his time in finance, Mavrookas graduated in 2003 from Rutgers University with a degree in computer engineering. He then joined the Navy, spending 11 years as a Navy SEAL, including eight deployments and five years on SEAL Team Six.\u00a0<\/p>\n

That high-stakes experience dramatically shaped how he approaches decision-making as a CEO. Mavrookas has said one of the biggest lessons he took from his time as a SEAL was the importance of making decisions with the information available\u2014and then executing quickly.<\/p>\n

\u201cA good decision doesn\u2019t always have a good outcome, and a bad decision doesn\u2019t always have a bad outcome,\u201d Mavrookas said in an interview with McKinsey earlier this year.<\/p>\n

\u201cYou have to focus on the decision-making process. Make good decisions with the information that you have and then execute adeptly. A perfect plan with mediocre execution will lose to a mediocre plan with excellent execution every time. Our goal is to deter a conflict, regardless of when it happens.\u201d<\/p>\n

Fortune<\/em> reached out to Saronic for further comment.<\/p>\n

JPMorgan CEO Jamie Dimon says Navy SEAL traits are good for business<\/h2>\n

Navy SEALs have long been up as a model for speed, execution, and accountability\u2014critical traits that carry into the business world.<\/p>\n

In fact, JPMorgan Chase CEO Jamie Dimon has specifically pointed to the SEALs as an example of how he wants small teams inside his 300,000-employee-strong finance giant to operate.<\/p>\n

\u201cThe teams needed to tackle [specific problems] should be small and authorized with the decision-making ability to move and act like Navy SEALs or the Army\u2019s Delta Force,\u201d Dimon wrote in a letter to shareholders earlier this year. \u201cThis is trench warfare; it\u2019s about fighting for every inch, moving quickly, and getting things done.\u201d<\/p>\n

Dimon and Mavrookas have another interest in common: shipbuilding. As the U.S. looks to revitalize its domestic construction, Dimon has become increasingly vocal about the need to train a new generation of skilled workers to build the ships.<\/p>\n

\u201cWe need 300,000 electricians, welders, etc. to build ships in the next five or 10 years,\u201d Dimon told CNBC<\/em> in July, speaking from the Philadelphia Navy Yard.<\/p>\n

\u201cIt fits what we call the American dream: getting kids skills or all workers\u2019 skills that they have jobs that could pay 80-, 90-, $100,000 a year after you know a year or two of training. This lifts up America. It helps build the defense industry,\u201d Dimon added.<\/p>\n

As Saronic works to expand the shipbuilding industry through its new products and technological advancements, JPMorgan has committed $24 million through loans and philanthropic grants to support a new submarine manufacturing and assembly facility in Philadelphia. The funding is also expected to expand workforce training and apprenticeship programs for \u201cthousands\u201d of prospective welders, electricians, pipefitters, and other skilled trades workers.<\/p>\n<\/div>\n
