Wolt co-founder Mikko Miki Kuusi has retained his position as Finland’s highest earner for the fourth consecutive year, after reporting a total income of more than 131 million euros in 2025. The 37-year-old businessman paid approximately 64 million euros in taxes, according to figures published by the Finnish Tax Administration.
The annual publication of tax information, commonly known in Finland as “tax day” or “envy day”, took place on Thursday. The release allows the public to examine the taxable earnings of high-income individuals across the country. This year’s figures cover people whose taxable income exceeded 120,000 euros.
Kuusi, who co-founded the food delivery company Wolt, recorded 113.5 million euros in earned income and a further 18 million euros in capital income in 2025. He currently heads Deliveroo, the British food delivery company.
His earnings placed him well ahead of other high-income individuals in Finland. Businessman Risto Siilasmaa came second, reporting total income of 63.8 million euros. Siilasmaa is known for founding cybersecurity companies WithSecure and F-Secure.
Saber Kordestanchi, one of the founders and owners of software company Hostaway, ranked third with earnings exceeding 42.5 million euros.
