Kiwi.com
Kiwi.com is a Brno-founded online travel agency that uses proprietary Virtual Interlining technology to combine flights from airlines that do not formally codeshare, creating unique multi-carrier itineraries unavailable on traditional booking platforms. The platform searches across 750+ carriers including low-cost airlines, trains, and buses to find the cheapest routes. Founded in 2012 by Oliver Dlouhy, the company grew rapidly and became one of the largest travel booking platforms in Europe, processing tens of millions of bookings annually. Kiwi.com also offers a Guarantee product that protects travelers on self-transfer connections.
Klarna
Klarna is a Swedish fintech company that pioneered the “buy now, pay later” (BNPL) model globally. Founded in 2005 by Sebastian Siemiatkowski, Niklas Adalberth, and Victor Jacobsson, Klarna started by offering online shoppers in Sweden a way to purchase goods on invoice (pay after delivery). Over the next decade, the company expanded across Europe and beyond, becoming a dominant online payments provider. As of 2021, Klarna was Europe’s highest-valued private tech company at $45.6 billion, reflecting meteoric growth fueled by consumers’ appetite for installment payments. Klarna’s app and services allow users to split purchases into interest-free installments or pay later, and it partners with over 450,000 retailers worldwide, including global brands like H&M, IKEA, and Nike. The company has over 150 million users across 45 countries and handled $80 billion in transaction volume in 2021. Klarna’s journey, however, has seen dramatic swings: after reaching a $45B valuation in mid-2021, a combination of rising interest rates and tech market downturn led to a downround in 2022, cutting its valuation to $6.7 billion (an 85% drop). The company restructured, laying off 10% of its staff, and refocused on profitability. By 2023, Klarna returned to profit and saw renewed growth, aided by expanding beyond BNPL into a full shopping app with price comparison, loyalty features, and banking services (Klarna obtained a banking license in Europe in 2017). In 2025, Klarna reportedly delayed an IPO amid market volatility but ultimately went public in September 2025, raising $1.37 billion. Despite valuation fluctuations, Klarna remains the global leader in BNPL, with a strong brand among Gen Z and millennial shoppers. Its journey from a small Stockholm startup to a financial giant serving 65 million customers (2025) at one point valued at $75 billion exemplifies the rise (and resiliency) of Europe’s fintech sector.

Kneip
Kneip is a Luxembourg-founded investment-data and fund-reporting company that sits in the plumbing between asset managers, fund domiciles, and the distribution channels (banks, platforms, regulators) where funds are actually sold. For decades it has been one of the largest providers of European fund data dissemination, handling NAVs, KIIDs/PRIIPs KIDs, MiFID II data templates, and regulatory reporting packages for hundreds of asset managers — unglamorous but absolutely load-bearing infrastructure for the EUR 5-trillion-plus Luxembourg fund industry. In 2022 Kneip was acquired by Deutsche Börse and integrated into the group's data-services business, effectively turning a Luxembourg-grown fund-tech operator into part of a top-tier European exchange's data franchise. It is a clean example of how Luxembourg's tax and legal specialization in funds translates into globally relevant software companies that outsiders rarely hear about.
