description: 'Buzzer was a mobile live-sports streaming startup founded in 2020 by Bo Han, formerly director of live content
  at Twitter. Its consumer app, launched in 2021, sold micropayment access — as low as $0.99 to $1 — to short in-game moments
  of live sporting events, targeting Gen Z fans who would not buy a full cable or league subscription. Buzzer secured streaming
  rights covering the NBA, WNBA, NHL, PGA Tour and ATP Tour, and raised roughly $44 million in total, including a $20 million
  Series A in June 2021 co-led by Sapphire Sport and Canaan Partners alongside a large group of athlete and team-owner investors.
  On 19 May 2023 the company shut down the direct-to-consumer app and pivoted to a business-to-business model branded "Powered
  by Buzzer", announced as API licensing, custom development and consulting for leagues, teams and networks streaming direct
  to fans. That offering never reached public availability: Buzzer ceased all operations on 30 June 2023, citing "recent fundraising
  developments and market dynamics". No public developer portal, API documentation, specification, SDK or package was ever
  published. The buzzer.com domain no longer hosts the company and now redirects to an Atom.com domain-for-sale listing. Retained
  in the network as a historical record of a defunct company; not an active API provider.'
