On 12 September 2025 Big Technologies published a litigation update (RNS 0481Z) setting out extensive allegations concerning its former CEO, Sara Murray, and associated parties. The announcement is a central source for this investigation. The summary below uses attribution throughout.
Undisclosed interests
Big Technologies alleged that Sara Murray had failed to disclose interests or relationships with certain entities, and that this affected the disclosure of her interests around the AIM IPO. The entities the company named were:
The company said the alleged non-disclosure affected the stated extent of Murray's interest in Big Technologies at the time of its admission to AIM. This is examined further on the IPO Questions page.
Untrue information
Big Technologies alleged that untrue information had been provided to the company, to its lawyers, and in statements filed with the court. The company attributed this conduct to Murray and associated parties. These are allegations; they have not been tested or established by a court.
Alleged financial diversion
Big Technologies alleged that more than £19 million had been improperly diverted or extracted from the company or its group companies to Murray or connected persons. This figure is the company's allegation as to the scale of the conduct it describes; it is not an audited or judicially determined loss.
Document allegations
Big Technologies alleged that certain documents — including purported Buddi board minutes and emails — had been forged or deliberately falsified. This publication does not state that Murray forged documents. The correct formulation is that Big Technologies alleged that documents had been forged or deliberately falsified by Murray or associated parties. The allegation is denied.
All matters summarised on this page are Ongoing. Sara Murray has denied the allegations. Mediated discussions ended in September 2026 without settlement, and the company stated it would continue litigation.
The other side
Sara Murray's publicly reported response, including her description of the allegations as "outrageous", is set out on the Sara Murray response page. Where Big Technologies subsequently rebutted her statements, both sides are linked.
