Tell Me About Yourself and Nul

I鈥檓 an entrepreneur and investor who has spent the last decade backing and building technology companies across health, fintech and consumer internet, including co鈥慺ounding Talis Capital and helping early companies like Darktrace and Onfido scale globally. After years of supporting founders from the investor side, I wanted to tackle a problem that felt personally meaningful and massively underserved: alcohol use disorder.

NUL is an alcohol鈥憆eduction tele鈥慼ealth company that combines evidence鈥慴ased medication, proprietary therapy and a frictionless digital experience to help people change their relationship with alcohol in a way that is discreet, humane and grounded in science.

What Inspired You To Start Nul, and What Problem Were You Trying To Solve?

Alcohol is one of the most harmful legal drugs in society, yet treatment options are still dominated by 90鈥憏ear鈥憃ld abstinence鈥憃nly models like AA and expensive in鈥憄atient rehab with very high relapse rates. At the same time, only a tiny fraction of people with alcohol use disorder ever receive medication, despite decades of data showing that drugs like naltrexone can reduce cravings and support lasting change.

Having seen how tele鈥慼ealth and GLP鈥�1s transformed obesity care, the idea with NUL was to create the 鈥淥zempic for alcohol鈥�: a modern, digital鈥慺irst programme that makes proven medication and therapy accessible, non鈥慾udgemental and genuinely effective.

What Has Been Your Biggest Challenge So Far, and How Did You Overcome It?

The biggest challenge has been changing perceptions around what 鈥済etting help鈥� for drinking looks like, because many people either do not identify with the label of alcoholism or feel that traditional rehab and AA are not for them. To overcome this, NUL has focused heavily on education and brand: clear, stigma鈥慺ree language, content in mainstream outlets, and a product experience that feels more like a modern wellbeing service than a clinic.

By giving people the option to keep living their lives, continue drinking while they reduce, and engage privately via fast online consultations and discreet medication delivery, we lower the psychological barrier to starting treatment.

Can You Describe a Pivotal Moment That Significantly Shaped the Direction of Nul?

A pivotal moment was seeing the early cohort data from our UK test launch in 2025, where just a few months of small鈥憇cale marketing produced over 100 paying customers and a revenue run鈥憆ate of roughly 拢250k with strong unit economics. That traction validated both the demand for a science鈥慴ased alcohol鈥憆eduction programme and the scalability of our subscription model, convincing us to accelerate plans for clinical trials with NHS partners and to prepare for a larger UK and future US rollout. It was the point at which NUL shifted from an experiment to a company with the potential to build the leading global brand in alcohol鈥憆eduction tele鈥慼ealth.

How Do You Define Success?

For your business: For NUL, success means helping large numbers of people drink less, feel better and avoid the long鈥憈erm health and social harms associated with alcohol, while proving this rigorously through clinical trials and real鈥憌orld data. Commercially, it is about building a sustainable subscription business with excellent unit economics, low customer鈥慳cquisition costs and the scale to become the default digital destination for anyone looking to change their relationship with alcohol.

As a founder: Personally, success is doing work that matters enough to feel uncomfortable: leaving a successful investing career to build NUL only made sense because the mission is bigger than any single funding round or valuation. If, in ten years, millions of people can access effective alcohol support as easily as they access food delivery or streaming services today, and NUL has meaningfully contributed to that shift, that will feel like time well spent.

What Advice Would You Give To Someone Thinking About Launching Their Own Startup?

Start with a problem that is both painfully real and structurally mis鈥憇erved, because conviction about the problem is what carries you through the inevitable volatility of startup life. Then be brutally honest about distribution and economics from day one: at NUL we designed the product around tele鈥慼ealth, generic medication and subscription pricing precisely so that helping people at scale would also make business sense. Finally, surround yourself with people who are smarter than you in their domain 鈥� from addiction medicine and therapy to brand 鈥� and give them the context and autonomy to build.

What鈥檚 Next for Nul? Any Exciting Developments We Should Watch Out For?

The next chapter is about deepening the clinical backbone of NUL and scaling access. We are working with NHS Manchester University NHS Foundation Trust and researchers from King鈥檚 College London and Manchester Metropolitan University on first鈥憃f鈥憈heir鈥慿ind clinical trials to measure the impact of NUL鈥檚 programme on surgery outcomes and alcohol intake. Alongside that, we are gearing up for a full UK launch, continued growth marketing, and laying the groundwork for expansion into the US, with a view to raising a larger round to scale rapidly once the model is fully proven.

Founder鈥檚 5 with Matus Maar Of Nul

We wanted to know a bit more about Matus, so we’ve put together the exclusive Founders’ 5 with Matus Maar of Nul.

Favourite business tool

Notion and Figma together are hard to beat: one gives the team a shared brain for documents, product specs and investor updates, and the other allows rapid iteration on brand and product experience without heavy engineering cycles.

One lesson you learned the hard way?

In both investing and building companies, waiting for 鈥減erfect鈥� information usually means missing the window; at NUL we learned to launch, test and iterate quickly rather than over鈥慹ngineering the first version of the programme.

One future trend you鈥檙e watching?

The convergence of tele鈥慼ealth, behavioural science and generics 鈥� the same forces that enabled GLP鈥�1鈥慴ased obesity treatments 鈥� is starting to transform addiction care, with medications like naltrexone finally getting the 鈥淰iagra moment鈥� they deserve. This will normalise evidence鈥慴ased treatment for alcohol in the same way digital health has normalised therapy and weight鈥憀oss drugs.

One quote you live by

鈥淧rogress is more important than perfection,鈥� which captures the philosophy behind NUL鈥檚 approach of helping people drink less on their own terms rather than demanding instant, absolute abstinence.

One book/podcast you recommend

For founders, 鈥淭he Hard Thing About Hard Things鈥� by Ben Horowitz is still one of the most honest accounts of what it feels like to build through chaos. For anyone interested in addiction and behaviour change, reading about The Sinclair Method and pharmacological extinction gives a very different, hopeful lens on alcohol treatment.
