Mark Daeche is a British technology and energy entrepreneur whose career spans software, telecommunications, household energy and cybersecurity. He is best known as one of the founders of First Utility, the independent energy supplier that challenged Britain’s major power companies by using technology, smart meters and more accurate customer billing. Long before entering the energy sector, he had already built experience in international software businesses and telecommunications, giving him a strong technical foundation for his later ventures.
His business career has included senior positions at Fox Software International and Xitech Inc., the creation of First Telecom, work with M2 Investments and more than a decade connected with First Utility. Following the sale of First Utility to Shell, he returned to technology through Locked Stack, a cybersecurity and data-privacy company. Away from business, he became widely known because of his marriage to entrepreneur, former model and television personality Amanda Cronin.
Who Is Mark Daeche?
Mark Daeche is a British entrepreneur and software engineer by training. Over several decades, he has built and managed businesses in Britain, continental Europe and the United States. Although he has worked across different industries, technology has remained at the heart of his professional life. His ability to combine software with large customer-service operations became particularly important during his years in telecommunications and later in the household energy market.
He is now professionally based in Monaco and remains active through Locked Stack. His career is notable because he entered the energy industry from a technology background rather than following a traditional route through utilities. This allowed him to approach energy billing, customer data and smart meters from a different perspective, helping First Utility establish itself as a serious challenger to Britain’s established suppliers.
Mark Daeche Age and Early Life
Mark Daeche was born in June 1963, making him 63 years old as of August 2026. UK corporate records confirm his birth month and year, British nationality and periods of residence in Switzerland and Monaco. His exact day of birth has not been firmly established, so June 1963 remains the most accurate date to use.
Technology became central to his working life from an early stage. He trained as a software engineer and developed his career during a period when personal computers and database software were becoming increasingly important to businesses. His education included time at St Columba’s College in St Albans, and his professional path soon took him into international software management. The experience he gained in databases, billing systems and customer-care technology later became highly valuable when he moved into telecommunications and energy.
Mark Daeche Career at Fox Software International
One of his earliest significant executive positions was at Fox Software International, where he served as managing director between 1988 and 1992. The company was known for database products including FoxBase and FoxPro, which became widely used during the expansion of personal computing. Fox Software was acquired by Microsoft in 1992, bringing its technology into one of the world’s largest software companies.
This period gave Daeche practical experience in a fast-growing international technology business. He worked during an era when database software was changing the way companies stored, organised and used large amounts of customer and commercial data. Those skills would later influence his approach to businesses that depended on accurate billing and customer management.
Mark Daeche and Xitech Inc.
After his time with Fox Software, Daeche became President of Xitech Inc., serving from 1992 to 1995. Xitech specialised in billing and customer-care software for the American telecommunications sector, placing him directly within an industry that depended heavily on technology to manage large numbers of customers.
His work at Xitech was an important bridge between his software career and his later entrepreneurial ventures. Telecommunications companies needed accurate billing, reliable databases and efficient customer-service systems, all areas in which he had already gained experience. The knowledge he developed during this period became especially useful when he began creating his own telecoms business.
Mark Daeche and First Telecom
During the mid-1990s, Daeche founded First Telecom plc, with his professional history placing his founder role from 1995 until 2000. The company provided telecommunications services and developed into a significant business, attracting hundreds of thousands of customers before its eventual sale.
First Telecom demonstrated Daeche’s ability to compete against much larger companies by using technology and alternative pricing models. By 2000, the company had built a substantial customer base, and it was sold to Atlantic Telecom. The exact amount he personally received from the transaction has not been disclosed, but the sale represented an important commercial success and gave him the opportunity to pursue further investments.
Following First Telecom, he became a partner in M2 Investments, where his career history places him between 2000 and 2008. This period helped bridge the gap between his telecommunications work and his later move into the British energy industry.
Mark Daeche and First Utility
First Utility became the business most strongly associated with Daeche’s name. His own professional history dates his role as founder from June 2006, while formal directorships connected with the business began in October 2008. The difference reflects the distinction between the early development of a venture and later corporate appointments.
The company was created to challenge Britain’s dominant household energy suppliers. Rather than relying only on traditional utility methods, First Utility made technology a central part of its model. Smart meters, more accurate billing and detailed household energy data were used to give customers greater control over their electricity and gas use. Daeche’s previous experience in telecoms made this approach particularly logical because both industries involved large customer bases, complex billing structures and huge quantities of usage data.
How First Utility Challenged the Energy Market
First Utility’s strategy centred on giving households clearer information about the energy they consumed. At the time, many customers still relied heavily on estimated bills, which could lead to confusion and unexpected charges. Smart meters offered a more accurate way to record consumption and allowed customers to understand their usage more clearly.
Daeche believed that technology already used successfully in telecommunications could help transform household energy. That idea helped First Utility develop from a small challenger into a major independent supplier. By the time Shell moved to acquire the business, First Utility was serving hundreds of thousands of households across Britain.
Mark Daeche’s First Utility Stake
Daeche also held a substantial financial interest in the company. Financial coverage in 2015 placed his First Utility ownership at approximately 18% to 20%. This stake became highly significant when Shell decided to purchase the business.
The size of his holding is one of the strongest reasons he is regarded as a wealthy entrepreneur. Rather than relying solely on celebrity-based wealth estimates, his ownership of a major energy company provides a clear indication of the scale of his business success.
First Utility Sale to Shell
Shell agreed to acquire First Utility in late 2017, with the transaction completed on 28 February 2018. The official purchase price was not publicly disclosed, although contemporary financial coverage valued the deal at approximately £240 million.
Based on estimates of Daeche’s ownership, financial calculations at the time placed the possible value of his stake near £48 million. This should not be treated as a confirmed personal payment because the final transaction terms and his exact proceeds remained private. Nevertheless, it gives a useful indication of how valuable his First Utility investment had become by the time of the Shell acquisition.
Following the takeover, First Utility became part of Shell’s household energy operations and was later associated with the Shell Energy brand. Daeche’s directorships connected with the business ended on the same date the acquisition was completed.
Mark Daeche Companies and Directorships
Corporate records connect Daeche with several British businesses. He became a director of Impello Limited on 17 October 2008 and remained in the role until 28 February 2018. He also held a directorship in the company now known as Octopus Energy Operations 2 Limited during exactly the same period. Both appointments were connected with his First Utility years, and his country of residence at that stage was given as Switzerland.
His later corporate history reflects a move to Monaco. In November 2021, he became a director of 7 Upper Belgrave Street Limited, with Monaco given as his country of residence. The company was subsequently dissolved. These records fit his wider professional timeline, which shows him gradually moving away from household energy and back towards technology ventures.
Mark Daeche and Locked Stack
Mark Daeche’s more recent career has returned him to the world of software through Locked Stack. His professional history states that he became a co-founder in April 2021, based in Monaco. Locked Stack identifies him as Co-Founder and Chairman of the Board, placing him in a senior strategic position within the company.
The business focuses on cybersecurity and data privacy, two areas that have become increasingly important as organisations handle greater volumes of sensitive digital information. His involvement brings his career back towards the technical world in which he originally trained, while also drawing on decades of management and entrepreneurial experience.
Mark Daeche Net Worth
The precise value of Mark Daeche’s personal fortune has never been publicly confirmed. A figure of approximately $50 million has circulated in entertainment coverage, while other publications have placed his wealth near £40 million. These amounts are estimates rather than audited personal financial figures.
A stronger indication of his financial position comes from his business history. His substantial ownership in First Utility, combined with the estimated £240 million value of Shell’s acquisition, led to calculations placing the possible value of his stake near £48 million. His earlier success with First Telecom and later investments may also have contributed significantly to his wealth. It is therefore reasonable to describe him as a multi-millionaire entrepreneur, while avoiding the claim that any exact current net-worth figure has been officially established.
Mark Daeche and Amanda Cronin
Mark Daeche’s personal life gained wider attention through his relationship with Amanda Caroline Cronin, a British entrepreneur, former model, skincare founder and television personality. The couple met at Nobu in London and developed a relationship years before their eventual wedding.
They married in Morocco in 2013 and lived an international lifestyle that included time in London, Monaco, France and Switzerland. Their marriage brought together a blended family, while the pair also became familiar faces at high-profile social events in places such as Cannes and Monaco.
Mark Daeche Divorce from Amanda Cronin
The marriage later deteriorated, and Amanda asked for a divorce in May 2017. The legal divorce was completed in 2019. Their separation attracted substantial media attention because of Daeche’s business wealth and Amanda’s increasingly visible public life.
Amanda received a multi-million-pound divorce settlement, although the exact value has remained private. Later entertainment coverage circulated a figure close to £40 million, but this amount has never been officially confirmed. The safest description is therefore that the settlement was substantial without presenting the £40 million figure as an established fact.
Mark Daeche Children
Later accounts of the marriage describe Mark and Amanda as having a blended family. Amanda had her daughter, artist Sofia Yeganeh, from an earlier relationship, while Mark had two children of his own. Their names, ages and careers have not been firmly documented, and they have remained outside his public business life.
Some older coverage incorrectly connected Sofia with Daeche as his biological daughter. The stronger later timeline supports the position that Sofia was Amanda’s daughter from a relationship before Mark. For accuracy, his family life is therefore best described as involving two children of his own and a stepfamily relationship with Amanda’s daughter during their marriage.
Mark Daeche New Wife and Current Partner
There is currently no dependable evidence that Daeche has remarried since his divorce from Amanda Cronin. No current wife, girlfriend or partner has been publicly confirmed, and he has kept his romantic life largely private in recent years.
His professional activity is much easier to establish. Current career material connects him with Monaco and Locked Stack, while his private relationships remain outside the spotlight. For that reason, claims naming a new wife or partner should be treated cautiously unless supported by direct evidence.
Where Is Mark Daeche Now?
Mark Daeche is now based in Monaco and continues to work in the technology sector through Locked Stack. His professional journey has moved from PC database software and American telecoms systems to First Telecom, household energy, investments and cybersecurity.
At 63, his strongest business legacy remains First Utility. The company demonstrated how software, smart-meter data and modern billing systems could help a smaller supplier challenge some of Britain’s biggest energy businesses. His career shows a consistent ability to apply technology to industries undergoing change, while his success with First Telecom and First Utility has established him as a significant British entrepreneur.
