In our How I Manage My Money series, we aim to find out how people in the UK are spending, saving and investing money to meet their costs and achieve their goals.
This week we speak to Alexander Dzhienbaev, 27, who lives in London. Alexander is the chief executive and founder of Thytadel, a tech business. Alexander pays £7,000 a month to rent an apartment in Mayfair and spends large sums on eating out and going to the gym. The entrepreneur does not add any money to a pension and adds £3,000 a month to investments, mainly cryptocurrency.
Monthly budget
My monthly income: My monthly income is around £20,000, but this varies. This comes from a combination of salary and director loan repayments from my company, Thytadel, as well as occasional withdrawals from my investment portfolio, and money from a recent 2025 licensing deal.
My monthly outgoings: Rent for my serviced apartment in central London, £7,000; apartment servicing, £450; council tax, £101.85; groceries, £900; electricity, £149; water, £60; broadband, £20.99; mobile, £34; dry cleaning, £90; subscriptions like YouTube Premium, £34.97; car insurance, £173.76; car fuel, £300; car valeting, £270; car parking, £585; car servicing, £90; eating out, mainly for meetings, £2,000; takeaways, £490; E by Equinox St James’s gym, £470; money into investments, around £3,000. I also spend money on sailing when needed. I don’t spend much money on clothes.
I grew up in Moscow, Russia, with my family, which has a background in professional sailing. Before going into business, my father competed as an Olympic yachtsman and later served as a head coach for the 2012 Olympics in London.
As a family, we were financially stable, enabling me to study civil engineering at university in Russia and a Master’s in entrepreneurship at University College London (UCL).
From a young age, I became interested in emerging technologies and was curious about mobile app startups like Instagram. I was always fascinated by the idea that anyone could launch an app from a laptop. This sparked my interest in becoming an entrepreneur.
I now run my own tech business called Thytadel, which I started in 2021 after graduating from UCL. The company initially focused on using artificial intelligence (AI) to help assist with drowning incidents in recreational environments.
In the early stages, I patented a safety technology designed to track location and trigger an immediate response in emergency situations.
As the company developed further, I identified an opportunity in distributed computing infrastructure for AI providers. We now provide the tech that helps supply the engine that AI tools need to operate.
The business is still in a growth phase, so most of my personal income currently comes from the licensing deal made in 2025.
I set up my business right after I completed my thesis at UCL. I first had to sort out my residency in the UK, which I did via the Innovator Founder visa route. This gives people the chance to get UK residency within a couple of years by meeting certain criteria, such as investing a specified sum into the economy.
It was challenging to navigate all the requirements and deal with all the different bodies involved.
Since being in the UK, I have not invested in traditional stocks or conservative savings accounts. I prefer to invest in researching industries or topics to identify potential market growth opportunities. If nothing stands out, I tend to allocate capital into cryptocurrency assets, which are highly liquid and can, in my view, be sold conveniently without the restrictions associated with structures like ISAs.
I typically add around £3,000 per month to investments. I sometimes also invest in competitor businesses. I have just shy of £500,000 in cryptocurrency, which I treat as cash. I don’t have any Isas.
I rent a one-bedroom apartment with a small balcony in Mayfair, central London, for £7,000 per month. It is a serviced apartment within the Mandarin Oriental chain. I pay an extra £450 per month for additional services like cleaning and dealing with rubbish. The residential block has a small gym, as well as a swimming pool, spa, work area, lounge and 24-hour concierge.
I know I don’t take a conservative approach to renting. But for me it is important to be in central London and reduce my travel times to and from meetings. I also want to be surrounded by the best infrastructure possible. If I purchased a property, I’d want a freehold home within zone 1 in London.
At the moment, I am not contributing to any form of pension. I prefer to invest my money elsewhere and keep my money more accessible. I have not thought about what age I would like to retire by. I do know that I wouldn’t want to sacrifice my quality of life for a fixed monthly pension. I don’t know how much money I would need for a good retirement, but it would be difficult to live comfortably on just the state pension.
I’d like to get to a point where my company runs without being involved in the day-to-day operations. My main financial goal is to be able to pass on wealth to my future children in the form of companies or trusts.
