Some founders start with an established market. Others with a commercial insight. Others with a technology.
Dorian Haci’s story begins much earlier: with a child who almost looked forward to something in the house breaking, because that was the moment when he could finally open it up as he pleased.
Radios, video recorders, electronic devices — everything could be taken apart to discover what was inside. Putting it back together was a different matter. His parents would often be left with a few spare components and a very practical question: “What are we supposed to do with these now?”
That curiosity never disappeared.
What changed was the object of it.
Today, Dorian is no longer trying to understand what is inside a video recorder. He is working at the interface between the digital world and one of the most complex systems we know: the human nervous system.
Dorian is co-founder and CEO of MintNeuro, an Imperial College London spin-out developing semiconductors for neural interfaces and implantable medical devices. He is also one of the founders Excellis chose to back.
His story illustrates something fundamental about deep-tech investing: investing in a technology almost always means investing first in the people who will have to transform it, adapt it and bring it into the real world.
From Albania to Cuneo, then Turin
Dorian was born in Albania but moved to Italy as a child and grew up in Cuneo.
“Albania gave me my birthplace, but Italy gave me everything else,” he says. School, education, friendships and training: the foundations of his personal and professional life were built in Piedmont.
He did not come from a family of engineers. His father taught literature; his mother worked in accounting. His fascination with technology emerged almost spontaneously and was later recognised by people he met along the way. In high school, one teacher told him directly that he should study electrical or electronic engineering.
His parents did something that would prove decisive for the rest of his life: they did not choose for him. They encouraged him to pursue what he enjoyed and what he felt he could become good at.
From Cuneo he moved to Politecnico di Torino, where he studied electronic engineering. In hindsight, he places great value on an aspect of the Italian university model that is often criticised: the broad, theoretical foundation of the first years.
Mathematics, physics, Calculus I, II and III, before he truly entered the field of electronics.
For Dorian, that generalist foundation proved invaluable. It did not simply teach him a particular technology; it trained him to approach different problems before specialising in specific solutions.
During his Master’s degree, he combined two fields that seemed completely divergent: wireless systems design and biological and biomedical systems.
In reality, they were already the two pieces of the puzzle that, years later, would become MintNeuro.
The sliding door that led to Imperial
During his Master’s, Dorian had the opportunity to carry out his thesis abroad. He knew he wanted to leave Italy for a period, even if he did not yet have a precise project in mind. Like many students, he looked first to the United States; he jokes that he grew up watching Happy Days and dreaming about California.
A meeting with Professor Danilo De Marchi of Politecnico di Torino changed the trajectory. Dorian explained what he was interested in and several opportunities opened up: Columbia, Austin, Stanford and Imperial College London.
Imperial was initially the name he knew least. He started researching it, discovered an exceptional engineering environment and decided to pursue the opportunity.
It was 2014.
He moved to London for six months to work on an electronic board for biomedical DNA-amplification applications. For the first time, he was fully immersed in an advanced research group surrounded by highly specialised researchers.
Dorian noticed the difference from his own training: some colleagues had extraordinary depth of expertise in highly specific technical problems, while he brought broader engineering foundations. The two approaches, he would later realise, could complement each other.
Then came one of those sliding doors that change the course of a life.
It was a Saturday afternoon. Dorian was in the lab testing his board when Tim, his supervisor, asked what he planned to do after returning to Italy.
Dorian did not have a plan yet.
Tim told him there might be an opportunity to return to Imperial as a researcher.
“I think I went white,” Dorian recalls. He had not expected it.
He returned to Italy, completed his Master’s degree and still had to compete for the position like everyone else.
In 2015, he was selected.
And so the six-month stay in London became the beginning of a new life.

Where electronics met neuroscience
At Imperial, Dorian entered the field that would ultimately define his career: Next Generation Neural Interfaces.
As a child he had wanted to understand what was inside electronic objects. As he grew older, another curiosity emerged alongside it: understanding what happens inside us.
The brain and nervous system communicate through electrical signals. The ability to read those signals — and in some cases modify them through stimulation — opens the door to new ways of treating disease.
The project Dorian joined focused on epilepsy: developing an implantable device capable of reading brain activity and intervening through electrical stimulation before seizures occur.
He worked as a researcher while also completing a PhD. The project brought together Imperial College, UCL and Newcastle University, with engineers, clinicians and neuroscientists working side by side.
In that environment Dorian learned a skill that rarely appears in scientific papers but would later become essential as a founder: translation.
It was not enough to explain to another electronic engineer how a circuit worked. He also had to explain why it mattered to a clinician, a patient or an industrial partner.
Dorian learned to change his language depending on the person in front of him.
Later, he would do exactly the same with employees, customers and investors.
“When can my cousin have it?”
The frustration that eventually pushed Dorian toward entrepreneurship also emerged during those research years.
He was working on sophisticated technologies and could see extraordinary possibilities. But there was a gap that was hard to ignore between what was achieved in the laboratory and what actually reached the real world and changed a patient’s life.
When he told people he was working on technology for epilepsy, someone would ask: “My cousin has epilepsy. When can he have this?”
The answer was frustrating: perhaps in ten, fifteen or twenty years.
Research was essential. But Dorian wanted to accelerate the transition from knowledge to impact.
He began to think of a company as a vehicle for turning technology into a product, concentrating resources around a clear mission and moving innovation beyond the laboratory.
There was also a more specific insight. Dorian’s role in the research project was to develop chips for these devices. He realised it was not only their epilepsy project that needed this kind of electronics: other research teams and companies faced similar problems.
Designing semiconductors that can operate at extremely low power, occupy minimal space and remain close to the nervous system for years requires highly specialised expertise.
The problem was therefore much bigger than one application.
A company we will build together
In 2018, Dorian had his annual review with Tim, by then both his manager and supervisor.
It was the kind of meeting where you look back at the previous year, plan the next and discuss where you might be going.
At one point Dorian threw out a sentence almost as a provocation:
“In five years, I’ll be the CEO of a company we build together.”
Tim looked up from his notes, smiled and told him it was fairly ambitious considering where they were at the time.
“But I like the idea.”
What began almost as a joke became the starting point for a far more serious conversation.
What company? Solving which problem? With what technology? And most importantly: who actually needed it?
This is where the logic of the researcher began to evolve into the logic of the founder.
Extraordinary technology is not enough. There must be a problem for which that technology is a necessary solution.

From an epilepsy project to the MintNeuro platform
After completing his PhD, Dorian joined the Royal Academy of Engineering Enterprise Fellowship, allowing him to spend a year focusing not on academic research itself, but on building a venture.
Told this way, this step also looks linear. In reality, it was not.
His first application was rejected. He applied again six months later and was accepted. In the meantime, Imperial had already sent him the letter marking the end of his time there; a few more weeks and he would have had to find another job.
Another sliding door.
With support from the Imperial ecosystem and the Royal Academy, the spin-out that became MintNeuro began to take shape.
Epilepsy was the natural starting application because the team already had deep expertise and clinical relationships. But a broader insight soon emerged: the same fundamental electronics required to record from and stimulate the nervous system of people with this condition could also enable applications in Parkinson’s disease, neuromodulation, severe depression and other areas.
MintNeuro therefore chose to position itself at a more fundamental layer of the stack: the microchip.
Not necessarily to build every complete device, but to create the essential technological layer on which other companies can more easily develop new devices and new therapies.
Dorian draws an analogy with computing: it would make little sense for every artificial-intelligence company to design its own equivalent of an Nvidia chip from scratch. Yet in neurotechnology, companies are still often forced to develop highly specialised electronics internally.
The result is constant reinvention of the wheel.
MintNeuro wants to reduce that friction.
Its chips are designed to be extremely small and ultra-low power — essential requirements when electronics need to operate inside or very close to the human body.
Reducing size, power consumption and invasiveness is not simply about making a device more elegant. It can mean making a therapy accessible to people who today cannot benefit from devices that are too large or too risky.
That connection between a few millimetres of silicon and potential clinical impact is where MintNeuro becomes unmistakably deep tech.

A future between medicine and brain-computer interfaces
Talk about neural interfaces and the conversation inevitably reaches Neuralink and Black Mirror-like scenarios.
Dorian says that whenever an episode involving neural interfaces appears, friends message him asking what he thinks.
His outlook is positive, while recognising the risks it carries.
He sees a clear trajectory: computers moved from machines the size of rooms to personal computers, then smartphones in our pockets, smartwatches and wearables that sit increasingly close to the body.
The interface between humans and technology has been steadily moving closer to us.
For Dorian, a much more direct connection with the nervous system is a plausible next step. As with every major technological transformation, the implications will be both positive and negative. But the possibilities — starting with helping people affected by paralysis or neurological disease — are enormous.
MintNeuro starts there: not from a science-fiction narrative, but from concrete medical needs.
And it is building technology that could make part of that future possible.
Italy, diaspora and patient capital
After more than a decade in the United Kingdom, Dorian’s relationship with Italy is far from faded.
His wife is Italian, his children are growing up with Italian, British and Albanian identities, and Piedmont, Turin and Cuneo remain important personal reference points.
He sees the Italian education system as an underestimated asset: its ability to build broad foundations before narrow specialisation. And he says that, in the future, he would like to bring some of the entrepreneurial and technological knowledge he has gained abroad back to Italy.
For Excellis, this has particular significance.
Scientific and technological diaspora does not necessarily have to be viewed as a loss that must be reversed. It can be a network that needs to be connected. Value is created when an education acquired in Italy meets international laboratories, markets, capital and cultures — while keeping a bridge to its origins.
Fundraising has also been an education for Dorian.
Building a semiconductor company for implantable medical devices is not the same as launching a software product, shipping it and checking the metrics a few weeks later. There are physical timelines: design, tape-out, manufacturing and testing. There are complex supply chains. Then come qualification, regulation and the realities of the medical-device industry.
That is why Dorian talks about “patient deep tech”.
And that is why he looks for investors who are partners, not simply providers of capital: people who understand the technology’s timeline, open doors, introduce customers, help find talent and stay with the company for many years.
“It’s almost like getting married,” he says. If you are going to spend ten years with someone, it helps if the relationship is a good one.
When talking about Excellis, Dorian highlights precisely this ability to understand both the semiconductor foundation and the medical-device application layer.
It is a useful definition of what a deep-tech investor should try to do: not force a technology into impossible timelines, but help a company move as quickly as possible within the reality of the technology itself.
Don’t fall in love with the idea
At the end of our conversation, we ask Dorian what advice he would give to a young Italian researcher at Oxford, Cambridge, Imperial or another leading institution who is unsure whether to remain in research, join a large company or attempt the entrepreneurial path.
His first answer is persistence.
Stories tend to look linear in hindsight: application, fellowship, PhD, spin-out, investors.
But that is only the line connecting the points that worked.
Before Imperial, people had said no. Before the Enterprise Fellowship, there had been a rejected application. A startup itself exists continuously between one door opening and another closing.
If something genuinely matters, Dorian says, you have to be willing to try again.
Then comes the market.
A new technology is not enough. There must be a real problem it can solve. The best hammer in the world is of little use if there are no nails.
That is why he encourages researchers to talk about their ideas, seek feedback and engage with customers and partners.
Ideas are plentiful.
Execution is what makes them real.
And finally comes the sentence that perhaps best captures not only MintNeuro’s story, but something essential about being a founder:
“Be in love with the ambition, with the field you are working in. Not with the specific idea. That will keep changing.”
MintNeuro’s ambition has remained enormous: to help enable smaller, less invasive neural devices capable of improving people’s lives.
But the route has evolved.
From epilepsy to a platform. From the complete device to the chip. From research to a company. From an initial idea to what technology and the market revealed to be more important.
And this is precisely what Excellis looks for when investing in deep-tech founders.
Not someone who already has every answer.
Someone with enough depth to understand the problem, enough ambition to want to solve it, enough humility to change direction and enough determination to continue when a door closes.
For Dorian, there is one final ingredient without which the rest matters little: people. “If there is something you can’t do, you need to find someone who can.”
Technology evolves. The idea changes. The market provides feedback. Sliding doors continue to open and close.
But in the end, a company is built by a group of people who decide to walk through them together.
Perhaps that is the thread connecting the child in Cuneo who dismantled video recorders to the CEO of MintNeuro.
The curiosity to open something up and understand how it works is still there.
The difference is that today Dorian is no longer only taking things apart.
He is building.
A chip, a team and — potentially — one of the invisible building blocks of the neurotechnology of the future.
