On 28 May 2015 CEO Brendan Eich (creator of JavaScript and former CEO of Mozilla Corporation) and CTO Brian Bondy founded Brave Software. On 20 January 2016 Brave Software launched the first version of Brave with an ad-blocking feature, and announced plans for a privacy-respecting ad-feature and a revenue-sharing program. In June 2018 Brave released a pay-to-surf test-version of the browser. This version of Brave came preloaded with approximately 250 ads, and sent a detailed log of the user’s browsing activity to Brave for the short-term purpose of testing this functionality. Brave announced that expanded trials would follow. Later that month Brave added support for Tor in its desktop browser’s private-browsing mode. Until December 2018 Brave ran on a fork of Electron called Muon, which was marketed[by whom?] as a “more secure fork”. Nevertheless, Brave developers moved to Chromium, citing a need to ease their maintenance burden. Brave Software released the final Muon-based version with the intention that it would stop working and instruct users to update as its end-of-life approached. In June 2019 Brave started testing a new ad-blocking rule-matching algorithm (implemented in Rust) that Brave claims is on average 69 times faster than the previous implementation in C++. The uBlock Origin and Ghostery algorithms inspired the new algorithm. Brave launched its stable release, version 1.0, on 13 November 2019 while having 8.7 million monthly active users overall. At the time, it had approximately 3 million active users on a daily basis. Brave 1.0, running on Android, iOS, Windows 10,macOS, or Linux, integrated “almost all of Brave’s marquee features across all platforms”, according to engadget. Brave uses its Basic Attention Token (BAT) to drive revenue. Originally incorporated in Delaware as Hyperware Labs, Inc. in 2015, the company later changed its name to Brave Software, Inc. and registered in California, where it is headquartered. By August 2016, the company had received at least US$7 million in angel investments from venture capital firms, including Peter Thiel’s Founders Fund, Propel Venture Partners, Pantera Capital, Foundation Capital, and the Digital Currency Group. In November 2019, Brave launched an ad network which returns a 70 percent revenue share to users. The initial advertisements were coming from partners like Vice, Home Chef, ConsenSys, Ternio BlockCard, MyCrypto and eToro.
