Nairobi, Kenya — In a dramatic turn of events, self-styled corporate activist David Dimba, who has spent weeks publicly attacking the leadership of Standard Chartered Bank Kenya and Stanbic Bank over alleged workplace misconduct and governance failures, is now facing growing accusations that his campaign has crossed the line into extortion and corporate blackmail.
Insiders claim Dimba’s relentless public offensive is less about accountability and more about exerting pressure on senior executives for personal gain, with Stanbic Bank emerging as the focal point of his latest confrontation.
Dimba, who joined Stanbic Bank’s Bancassurance unit in late 2024 and identifies himself as Chairperson of the Bancassurance Association of Kenya, has taken his campaign to extraordinary lengths. Through a series of YouTube videos and LinkedIn posts, he has repeatedly declared himself the “incoming CEO” of Stanbic Bank Kenya. In one widely circulated post, he even announced his “official acceptance” of the position, claiming his appointment was only awaiting approval from the Central Bank of Kenya.
He has also shared videos showing himself being denied entry at Stanbic premises while attempting to report to work as the bank’s self-proclaimed chief executive, insisting he would not be intimidated.
According to sources familiar with the dispute, Dimba has effectively kept several bank executives under constant public pressure through a sustained campaign of online attacks, accusations and demands for their removal from office. Senior figures across Kenya’s banking industry are said to be increasingly concerned about becoming targets of his highly publicized campaigns, which critics describe as an attempt to hold executives at ransom through reputational damage and relentless public scrutiny.
Among those he has publicly targeted is Stanbic Bank Kenya Chief Executive Joshua Oigara, whom he has repeatedly urged to resign alongside other senior managers. Critics argue that his tactics have created a climate of fear and uncertainty within sections of the banking sector, where executives risk being subjected to weeks or even months of damaging allegations across social media platforms.
Dimba has framed his actions as part of a broader mission to fight what he describes as corporate exploitation, impunity and modern-day slavery within Kenya’s banking sector.
However, detractors argue that his methods have become increasingly aggressive. They point to a pattern of publishing videos demanding resignations, threatening to confront institutions directly and mobilizing public pressure campaigns against individuals and organizations he accuses of wrongdoing.
Some critics further allege that Dimba has built a reputation for launching highly personalized campaigns against senior corporate figures and then escalating pressure until his demands are addressed. While supporters view him as a whistleblower exposing wrongdoing, opponents contend that his approach resembles coercion rather than genuine accountability.
Dimba’s self-declaration as Stanbic’s chief executive has drawn widespread criticism and ridicule on social media, where many observers have described the move as grandstanding that undermines established corporate governance structures.
In one video, he dismisses objections to his claim and tells employees and management that he is “the official CEO of Stanbic Bank Kenya, whether you like it or not.”
Critics argue that such conduct risks damaging the bank’s reputation while trivializing legitimate concerns about workplace conditions and corporate accountability.
Some also warn that the constant public spectacle surrounding Kenya’s major lenders risks tarnishing the image of the country’s banking sector. By repeatedly portraying leading banks as corrupt, dysfunctional and hostile workplaces without regulatory findings or court determinations to support every claim, Dimba is accused of giving Kenyan banking a bad name both locally and internationally.
Analysts caution that while genuine wrongdoing must always be exposed, unverified allegations and highly personalized campaigns can undermine investor confidence, damage institutional reputations and create uncertainty in a sector that relies heavily on trust and stability. International investors and parent companies may view the ongoing drama as evidence of instability within Kenya’s financial services industry, even where allegations remain unproven.
The growing controversy has prompted calls for regulatory and law enforcement agencies to examine the allegations surrounding Dimba’s conduct.
Some industry stakeholders believe the Ethics and Anti-Corruption Commission, the Central Bank of Kenya and other relevant authorities should establish whether any laws have been violated and determine whether the allegations amount to legitimate whistleblowing, activism or something more serious.
Dimba initially gained attention through claims involving Standard Chartered Bank Kenya’s financial position, workforce reductions, pension obligations and dividend policies under Chief Executive Kariuki Ngari. Those disclosures resonated with some current and former employees who believed they highlighted genuine workplace concerns.
However, his subsequent claims of being Stanbic’s incoming chief executive, coupled with his increasingly personal attacks on senior banking executives, have led many observers to question whether his campaign remains rooted in public interest advocacy or has evolved into something more self-serving.
As the dispute escalates, Stanbic Bank and the wider financial sector continue to watch developments closely. While calls for corporate reform and accountability remain important, critics argue that such objectives must be pursued through lawful and credible channels rather than intimidation, self-appointed authority or public pressure tactics.
