Kahoot! is a game-based learning platform founded in 2012 in Trondheim, Norway, spun out of research at the Norwegian University of Science and Technology, with the mission of making learning awesome by transforming education and training into engaging, competitive, social experiences. The company was founded on the pedagogical conviction that active participation — answering questions under time pressure in a group setting — dramatically improves knowledge retention compared to passive instruction, and that the mechanics of games (points, leaderboards, competition) could be applied to any learning context from school classrooms to corporate training to social trivia. Kahoot! was built as a platform accessible on any device with a web browser, requiring no installation and enabling instant deployment in live group settings.\n\nKahoot!'s core product allows educators, trainers, and presenters to create multiple-choice quizzes, polls, and word puzzles — called kahoots — that participants join via a game PIN on their devices. The platform has expanded significantly into asynchronous learning, with Challenge mode for self-paced assignments, Courses for structured learning journeys, and an AI-powered question generator that accelerates content creation. Kahoot! at Work targets corporate L&D teams with branded training games, onboarding programs, and meeting engagement tools. The platform integrates with Microsoft Teams, Google Workspace, Canvas, and major LMS platforms, embedding Kahoot! into existing learning workflows.\n\nKahoot! reached $150 million in revenue as of October 2025 and has accumulated 4 billion participants across 200 countries, making it one of the most widely used educational technology platforms in the world. In 2024, the company was taken private in a $1.7 billion acquisition led by Goldman Sachs Alternatives, General Atlantic, and Kirkbi, reflecting institutional confidence in its growth trajectory despite the post-pandemic normalization of the EdTech sector. Its combination of extraordinary scale, freemium-to-enterprise monetization, and a product roadmap anchored in AI-assisted content generation positions Kahoot! as the dominant brand in interactive learning globally.
Global payments infrastructure founded by Patrick and John Collison (YC W10); $1.4T payments volume in 2024; $18B+ revenue; $106.7B valuation as of Sept 2025; powers everything from startups to Fortune 500 companies with developer-first API design.
Stripe is a global payments infrastructure company founded in 2010 by Irish brothers Patrick and John Collison, headquartered in San Francisco, California and Dublin, Ireland. Stripe was born from the insight that accepting payments online was unnecessarily complex for developers, and that a well-designed API could unlock an entire generation of internet businesses. The company went through Y Combinator's Winter 2010 batch and grew to become the defining payments infrastructure layer of the modern internet economy, processing payments for businesses in virtually every industry worldwide.\n\nStripe's platform provides payment processing, fraud prevention via Stripe Radar, subscription billing, revenue recognition, banking-as-a-service through Stripe Treasury, corporate card issuance, identity verification, and tax compliance tools. It serves a spectrum from early-stage startups to publicly traded enterprises including Amazon, Google, Salesforce, and Shopify. Stripe's developer-first philosophy — comprehensive documentation, SDKs in every major language, and a sandbox testing environment — created an ecosystem of millions of businesses built entirely on its infrastructure.\n\nStripe processed $1.4 trillion in total payment volume in 2024 and generates over $18 billion in annual revenue, with a valuation of $106.7 billion as of September 2025. The company has remained private longer than most comparably sized technology companies, giving it flexibility to invest in long-term product expansion. An April 2024 partnership with Apple Pay extended Stripe's reach further into mobile and in-store commerce. Stripe competes with Adyen, Braintree (PayPal), and Square, but its developer ecosystem depth and global infrastructure make it the default payments platform for a generation of technology companies.
