Founded in 2019 by serial entrepreneur Tarun Gaur after his mother lost money to an online scam, the company makes a privacy-first Smart Browser and Safe Search engine that deliver real-time scam and phishing protection, ad and tracker blocking, and biometric/PIN locks - without collecting browsing history or product analytics. qikfox claims to be the world's first browser to bake in both decentralized identity and quantum-resistant cryptography, and has since layered in an AI Copilot, 3D web, and knowledge-management features aimed at the emerging agentic web.

Founded in 2015 by JavaScript creator Brendan Eich and engineer Brian Bondy, Brave has grown into a full privacy suite: an independent search engine (Brave Search), a built-in AI assistant (Leo), a Web3 crypto wallet, a VPN, and an opt-in advertising model powered by the Basic Attention Token (BAT) that pays users and creators. In 2025 the browser passed 100 million monthly active users.
