The business landscape in Greece and the international fintech sector is witnessing one of the most intense corporate conflicts in recent years. The alliance that began in 2022, with JPMorgan acquiring a 48.5% stake in Viva Wallet (now Viva.com) for 800 million euros, has devolved into an all-out war of attrition. At the center of this storm is Viva’s founder, Haris Karonis, who, in his message accompanying the company’s financial statements, describes 2025 as a "revelatory year," directly accusing the American giant of a "devaluation strategy."
The Chronicle of a Foretold Rupture
When JPMorgan entered Viva’s share capital, the move was hailed as the ultimate vote of confidence in the Greek tech ecosystem. However, the reality behind closed doors was starkly different. According to Mr. Karonis, JPMorgan did not act as a strategic partner aiming for growth, but as a shareholder seeking to suppress the company's value to acquire it entirely at a bargain price.
The allegations are specific and grave. Karonis claims the bank used its veto rights and influence on the board to block critical expansion moves, such as entering the US market and developing new credit products. This "sabotage strategy," as he calls it, aimed to keep Viva’s valuation at levels near 1 billion euros, while Viva’s management estimated its true value exceeded 5 billion euros.
The Call Option: The Bone of Contention
The root of the problem lies in the Shareholders' Agreement (SHA) and the infamous "call option." JPMorgan has the right to buy out the remaining stake in Viva by 2025, under specific valuation conditions. If the company's value remains low, the bank can gain full control for a fraction of its potential worth.
- Valuation Dispute: Viva argues that its technology and presence in 24 European countries make it a leader in cloud payments.
- Growth Obstacles: Karonis' side alleges that JPMorgan refused to fund or approve strategic acquisitions that would have boosted revenue.
- Legal Warfare: Both parties are already in London courts, with cross-lawsuits concerning the interpretation of the agreement's terms.
Karonis does not hesitate to use harsh language, speaking of "corporate bullying" and an attempt to strangle a successful European business by an American banking titan. This stance reflects a deeper crisis of trust, where the founder feels his "child" is being threatened by its own investors.
JPMorgan’s Response and the International Dimension
For its part, JPMorgan maintains a more institutional stance, dismissing the allegations as baseless. Sources close to the bank state that their decisions are based on strict risk management and compliance criteria, as befits a global financial institution. They argue that Viva, as a neobank with a banking license, must follow specific capital adequacy rules, which Karonis' management may be underestimating in its pursuit of rapid growth.
"This is not just a shareholder dispute; it is a clash of two different worlds: the agile, risk-taking culture of startups and the conservative, regulated nature of traditional banking."
This case has taken on international dimensions, highlighting the risks European fintechs face when partnering with traditional banking giants. The question now is whether Viva.com can survive and grow in this toxic environment or if the judicial path will be the only solution for a divorce.
Conclusions and the Day After
The Viva-JPMorgan clash serves as a lesson for every startup founder seeking capital from institutional players. The importance of the "fine print" in shareholders' agreements proves decisive. For the Greek economy, this development is unfortunate, as one of the country's biggest successes (unicorns) is consumed in legal battles instead of focusing on innovation. 2026 will be the year of the final showdown, as the call option deadlines loom and the decisions of the British courts will determine the company's future.
