“There’s something special about this place. It’s a mix of brilliant minds from all over the world, all pushing each other to grow. Not just the products, but ourselves.”
Mickael Billard began his journey at Ledger in 2017 as a Senior Software Engineer, one of the company’s earliest technical hires. Back then, he was focused on building internal tools that would quietly power the business behind the scenes.
Seven years later, Mickaël now leads a team of ten. Together, they design and develop the infrastructure that enables Ledger to operate at scale, supporting global logistics, automating complex systems, and helping teams work smarter every day.
“When I started, we were shipping a few hundred orders a day. Then crypto exploded, and suddenly there were thousands. That kind of growth doesn’t just stretch your tools—it stretches your mindset. We had to rebuild everything to scale.”
He vividly remembers the day Ledger crossed the one million device sold mark.
“At the time, it felt unreal. It might seem like just a number now, but back then, it was proof that what we were building mattered. That we were helping people secure what’s theirs.”
For Mickaël, Ledger has always been about more than just technology. It’s about how things are built, and the people you build them with. Beyond engineering, he’s an active member of Ledger’s employee committee, helping shape internal culture and create moments of connection across the company. At home, he keeps a personal archive of every Ledger device and limited edition released over the years. He even brought a selection of that colle ction to his People of Ledger photoshoot—a small but meaningful glimpse into the journey he's helped shape.
“Each one tells a story. A launch. A challenge we overcame. A step forward.”
Whether he’s solving complex systems challenges or catching up with teammates over coffee, Mickaël says one thing has always remained the same: the feeling of building something meaningful, with people who care. And when asked how he explains his work to his family, his answer is simple.
“I told my grandmother, we’re not a bank. A bank can take your money—we can’t. We just protect it.”
