AdGuard
SeedSurf the web ad-free
Privacy-first ad blocker protecting users across all platforms, browsers, and apps.
About
AdGuard Software Limited builds a comprehensive suite of privacy and security tools anchored by its flagship ad blocker, which works system-wide on Windows, Mac, Android, iOS, and Linux — not just inside browsers. Unlike extension-only blockers such as uBlock Origin, AdGuard intercepts traffic at the network level, blocking ads, trackers, and malicious domains across every app on a device. The company also offers AdGuard DNS (a public privacy-focused DNS resolver), AdGuard Home (a self-hosted network-wide ad blocker similar to Pi-hole), and AdGuard VPN. Founded in 2009 in Moscow and now headquartered in Limassol, Cyprus, AdGuard has scaled to over 150 million global users while remaining largely bootstrapped, reaching $5.4M in annual revenue with a lean 49-person team. The company is profitable and has taken only minimal external capital from VTI Capital.
DailyDropout Take
AdGuard stands out as a rare bootstrapped success story in cybersecurity — profitable with 150M+ users and no significant VC funding. Their system-wide approach to ad blocking across all platforms gives them a defensible moat against browser-only alternatives.
Discovery signal: Revenue-generating bootstrapped company with massive user base and expanding product suite into DNS, VPN, and home network protection.
