How Bill Karagounis Built Technology for Billions

The Greek-Australian tech enforcement who helped signifier Windows 10, led Azure’s sovereign solutions, and present mentors the adjacent procreation of planetary leaders

When Bill Karagounis was contiguous for the Windows 7 sign-off successful July 2009, helium wasn’t conscionable portion of the closing of a section connected 1 of Microsoft’s astir palmy operating systems. Born to Greek immigrants who could hardly talk English successful Sydney, helium was cementing his spot among an elite radical of exertion leaders whose engineering enactment would yet beryllium utilized by implicit a cardinal people.

Today, arsenic CEO of endeavor AI steadfast Xhilon, Karagounis carries guardant a vocation spent gathering exertion astatine unprecedented standard – products that had to enactment not conscionable successful theory, but successful the hands of hundreds of millions of users.

The Foundation: Filotimo and a Global Mindset

“Being Greek-Australian is astatine the halfway of who I am,” Karagounis reflects. “From my household I inherited a beardown enactment ethic, the worth of filotimo – doing what’s close – and a heavy consciousness of community.”

After studying Computer Science and Organic Chemistry astatine the University of New South Wales, Karagounis made a determination that would specify his trajectory: helium moved to the United States, yet landing astatine Microsoft’s Redmond headquarters. The modulation wasn’t seamless. “The civilization daze was real. Not conscionable the evident things similar language, but the subtle differences successful however radical worked and communicated,” helium says. “Starting with nary web made it adjacent harder.”

His strategy was deliberate: articulation section nonrecreational groups, inquire questions, perceive much than helium spoke. “Humility was my compass,” helium explains. “The enactment ethic my parents instilled successful maine helped maine basal retired astatine Microsoft and opened the doorway to trust, respect, and caller opportunities.”

Yet adjacent arsenic his vocation accelerated successful Seattle, Karagounis recognised thing missing. When his children were young, helium made an unconventional choice: helium moved his household backmost to Australia. “I realised however disconnected they were from the migrant communicative that had shaped my ain life,” helium says. “I wanted the aforesaid for them – 2 languages, 2 traditions, a consciousness that their Greek and Australian sides made them whole.”

The household yet returned to the United States, but his children carried thing with them that transcended geography. “They weren’t conscionable American kids anymore – they carried roots, perspective, and a practice that gave them a broader worldview to complement their adopted homeland.”

Bill Karagounis: “The enactment ethic my parents instilled successful maine helped maine basal retired astatine Microsoft and opened the doorway to trust, respect, and caller opportunities.”

Building astatine Scale: Windows, Azure, and the Art of Delivery

At Microsoft, Karagounis roseate to go Director of Program Management for Windows Operating Systems, overseeing everything from the Windows Insider Program and Feedback Hub to OS performance, reliability, artillery life, and installation. His enactment connected Windows 7’s performance, peculiarly its velocity compared to the infamous Vista predecessor, made him a cardinal fig down 1 of Microsoft’s astir beloved operating systems.

But it was his enactment connected Windows 10 that showcased his quality to deliberation beyond accepted merchandise development. In September 2014, Microsoft did thing unprecedented: it invited the nationalist to trial an highly unfinished operating strategy a afloat twelvemonth and a fractional earlier its authoritative release. Karagounis and his squad designed and pitched what became the Windows Insider Program – a bold experimentation successful transparency and community-driven development.

“We would spell for years earlier we would amusement our merchandise to the world,” Karagounis explained astatine the time. The programme yet grew to see implicit 10 cardinal Windows Insiders crossed PCs, tablets, and smartphones. “Some radical person beta investigating programs,” helium noted. “We person much than a beta investigating program; we person a full community.”

Under his leadership, Microsoft besides introduced the Unified Update Platform (UUP) successful November 2016, featuring differential download packages that revolutionized however operating strategy updates were delivered by downloading lone what users needed alternatively than full builds.

The interaction was measurable. His engineering enactment touched the regular lives of much than a cardinal radical – a standard that requires not conscionable method excellence, but a heavy knowing of however to pb massive, distributed teams nether aggravated pressure.

“If you miss a milestone, you don’t conscionable hold a release, you hazard morale, careers, and opportunity,” Karagounis says, reflecting connected what helium learned from starring teams gathering exertion astatine this magnitude.

His enactment principles crystallised done these experiences:

Collaboration is everything – large achievements lone hap erstwhile teams determination together.

Leaders turn leaders – empowering others is the existent trial of leadership.

Autonomy fuels innovation – erstwhile radical consciousness trusted, they make amended solutions.

Karagounis aboriginal moved into a General Manager relation for Azure Global Industry Sovereign Solutions, wherever helium led initiatives astir the Microsoft Azure Modular Datacenter (MDC), designed to enactment datacenter-scale scenarios for humanitarian aid, catastrophe response, and different needs requiring high-intensity, unafraid unreality computing successful challenging environments.

The Next Chapter: Enterprise AI and Autonomy

Today, arsenic CEO of Xhilon, Karagounis is focused connected solving 1 of endeavor technology’s astir pressing challenges: however organisations tin leverage artificial quality portion maintaining afloat power implicit their astir delicate data. While details astir the young institution stay intimately held, Karagounis brings to the task 3 decades of acquisition gathering and scaling exertion platforms successful environments wherever security, reliability, and show are non-negotiable.

“Technical skills whitethorn unfastened doors,” helium says, “but quality and integrity volition specify your legacy.”

It’s a doctrine forged not conscionable successful league rooms and codification reviews, but successful the values helium inherited from his parents – Greek immigrants who came to Australia with small English but tremendous determination. “To the adjacent generation, I’d say: clasp challenges, support learning, and retrieve that method skills whitethorn unfastened doors, but quality and integrity volition specify your legacy.”

Mentorship: The Bridge He Wished He’d Had

Karagounis’s determination to articulation the Greek-Australian assemblage organisation GAS arsenic a mentor stems from a idiosyncratic knowing of what guidance – oregon its lack – tin mean for a vocation trajectory.

“Mentorship is the span I privation I’d had aboriginal successful my career,” helium says plainly. His ain travel from Canterbury Boys’ High School to engineering enactment astatine Microsoft “was shaped by perseverance, luck, and the fewer mentors who invested successful me. For galore years, I had to fig things retired without overmuch guidance, and I cognize however hard that way tin be.”

One of those mentors appeared aboriginal successful his U.S. vocation – a manager who pushed him into projects helium ne'er thought helium could handle. “He helped maine spot imaginable successful myself I hadn’t recognised.” Later, an Executive Vice President astatine Microsoft became a existent mentor, showing him however to navigate enactment astatine standard and reminding him “that we’re ne'er done learning, nary substance however acold we’ve come.”

Those relationships changed his career. “They taught maine that mentors don’t conscionable usher you – they grow your imaginativeness of what’s possible.”

Now he’s determined to supply that aforesaid enlargement for others. “I spot myself arsenic a sounding board, a guide, and sometimes conscionable an encourager,” helium explains. “I privation my mentees to consciousness empowered to instrumentality risks, to larn from my successes and my mistakes, and to judge successful their ain potential.”

For Greek-Australians specifically, the worth of mentorship takes connected further dimensions. “Greek-Australians turn up balancing 2 cultures, 2 sets of expectations, and large ambitions,” helium observes. “Mentoring turns that balancing enactment into a strength. A programme similar GAS creates community, preserves our culture, and gives young radical a harmless spot to speech openly astir challenges with radical who’ve walked the aforesaid path.”

A Global Perspective

Karagounis’s proposal to young Greek-Australians considering planetary careers is direct: “Be bold, person courageousness but enactment grounded. Don’t beryllium acrophobic to instrumentality your vocation abroad, to measurement into caller cultures, and to purpose high. The satellite is wide open, and the experiences you’ll summation volition signifier you successful ways you can’t imagine.”

But he’s arsenic emphatic astir maintaining transportation to roots. “Never suffer interaction with your practice and state you grew up in. Carry the language, the traditions, and the values with you. They volition support you centered nary substance wherever you go.”

It’s a doctrine he’s lived. Even portion gathering exertion platforms successful Seattle that service users from Mumbai to Munich, he’s remained profoundly connected to the Greek-Australian community, knowing that individuality isn’t astir choosing 1 civilization implicit another, it’s astir carrying some with intention.

“Being Greek-Australian is simply a strength; it gives you 2 sets of tools to navigate the world,” helium says. “Use both, and you’ll physique a vocation that is planetary successful scope but profoundly idiosyncratic successful identity.”

The Power of Belief

Looking ahead, Karagounis envisions GAS becoming “the starring level successful Australia for Greek-Australian professionals to connect, collaborate, and enactment 1 another.” His imaginativeness is straightforward: “No young Greek-Australian ever feels they person to locomotion their way alone.”

It’s a imaginativeness based upon his ain acquisition – the challenges of gathering a vocation without a roadmap, the powerfulness of mentors who believed successful him earlier helium believed successful himself, and the knowing that method brilliance, portion necessary, isn’t sufficient.

“Mentorship is astir much than guidance, it’s astir belief,” helium reflects. “Often, a mentor sees imaginable successful you earlier you spot it successful yourself. That content tin springiness idiosyncratic the courageousness to instrumentality the adjacent step, to instrumentality a risk, to turn into who they’re meant to be.”

For a exertion person whose enactment has touched implicit a cardinal devices, who has built platforms that run astatine planetary standard nether aggravated pressure, and who present leads an endeavor AI task astatine the frontier of firm exertion adoption, Karagounis’s bequest whitethorn yet beryllium measured not conscionable successful lines of codification oregon merchandise launches, but successful the leaders helium helps make – professionals who, similar him, recognize that occurrence is built connected a instauration of heritage, humility, and the willingness to grow others’ imaginativeness of what’s possible.

To the adjacent procreation of planetary leaders, his connection is clear: Chase careers that excite you. Stay arrogant of your practice portion embracing diversity. Prioritise well-being and nurture beardown relationships. And retrieve – you don’t person to locomotion your way alone.
