Company Overview
About Airtime
Airtime — formerly known as Mmhmm — is a video communication software company founded in 2020 by Phil Libin, the co-founder and former CEO of Evernote, and headquartered in San Francisco, California. The company launched Mmhmm during the COVID-19 pandemic as a virtual camera application that allowed users to create custom visual presentations, backgrounds, and on-screen layouts during video calls on Zoom, Google Meet, Teams, and Webex — turning video meetings into more dynamic, studio-like experiences. The product attracted significant attention from remote workers, content creators, educators, and business communicators seeking more polished and engaging video appearances.
Business Model & Competitive Advantage
Mmhmm raised $140 million in total funding, including a $100 million Series B in July 2021 led by SoftBank Vision Fund, with Sequoia Capital among its investors. In April 2025, Mmhmm rebranded to Airtime and launched two new products: Airtime Creator (an updated version of the original Mmhmm tool for building presenter-focused video presentations) and Airtime Camera (a lightweight app for customizing video appearance in any meeting platform). Shortly after the rebrand, the company underwent layoffs as it streamlined operations and refocused its product direction.
Competitive Landscape 2025–2026
Airtime competes in the video presentation and virtual camera market alongside tools like Loom, Descript, OBS Studio (open-source), and presentation features embedded in Zoom and Teams. The company''s core differentiation is the combination of ease of use, professional visual quality, and deep integration with existing video conferencing infrastructure — allowing users to enhance their video presence without switching platforms. Post-rebrand, Airtime is positioning itself as a toolkit for anyone who wants to look and present professionally in the growing universe of online video communication.
