AMW Analysis
Wispr AI develops a voice-interface product that converts natural speech into formatted text and commands across applications, using on-screen context awareness and support for over 100 languages, with a stated goal of enabling faster writing than typing. Founded in 2021 and based in San Francisco, the company has raised $81.0 million to date, including a $25.0 million Series A extension in November 2025 backed by investors such as Notable Capital, Menlo Ventures, NEA, 8VC, and Flight Fund, alongside a group of individual backers from other operating companies. Recent news flow shows the company describing that round as completed without a formal pitch process, at a valuation of $700 million, alongside reported 70% user retention and 40% month-over-month revenue growth.
Product development has extended platform coverage: following existing availability on Mac, Windows, and iOS, the company launched an Android app in February 2026, reaching what it describes as over 3 billion Android users worldwide. That release added a floating bubble interface, a reported 30% performance improvement from infrastructure upgrades, and a first Hinglish (Hindi-English) voice model aimed at the Indian market. Company messaging frames this progression as a shift from dictation software toward a broader "Voice OS" positioning.
