AI startup Hark, founded by serial entrepreneur Brett Adcock, has launched Hark Pro, a proactive AI assistant it describes as an “operating system for your life.” [4, 1] The service is available on the web, iOS and Android. [3, 4]

Hark Pro connects to users’ email and calendars to anticipate their needs and automate tasks, including booking travel, paying bills and resolving schedule conflicts. [3, 4] Hark has raised $700 million. [3, 5] Its valuation is $6 billion. [3, 5]

Hark Pro enters a competitive market, challenging products including OpenAI’s Dots and Meta’s Muse. [3, 5] Hark uses a freemium model, with paid tiers of $20 and $100 per month. [3] That pricing structure matches the one used by Meta’s recently launched agent. [3]

The current launch is software-based. Hark plans to debut dedicated hardware devices in 2027. [5]
