Company profile
researched Aug 2026Airtime, previously known as mmhmm, develops software tools for people who work over video. The product began as a virtual camera and presentation layer that sits between a user's webcam and existing meeting services such as Zoom, Google Meet, Microsoft Teams and Webex, placing the presenter on screen alongside slides and other content in a format closer to a television broadcast than a conventional screenshare. Users can import existing .ppt, .key or .pdf decks, add images, video and audio, resize and position elements including their own video image, and use custom backdrops; a copilot mode lets an assistant manage the on-screen elements or co-present. The software can also be used to record video for later playback and for interactive recordings that an audience can consume either as a video or as a deck.
In April 2025 the company rebranded from mmhmm to Airtime and reorganized its functionality into separate tools rather than a single application. Airtime Camera is a virtual camera for looking polished on live calls, with custom looks, environment and appearance controls, branding and logo overlays, background tinting, and in-the-moment reactions using GIFs and visuals. Airtime Creator is the direct successor to the original mmhmm app and retains its features, supporting presentations where the speaker appears within the slides, sectioned recording with quick edits, and up to 10 people on screen at once. The company's site also describes a quick-recording tool supporting desktop and web screen recordings of up to one hour in high definition, and Stacks, a live meeting collaboration tool positioned as an alternative to screensharing, which gathers materials of almost any media type into a document that persists after a call and shows real-time presence of attendees.
The desktop app runs on Mac and Windows (Windows 10 or 11), with a browser-based version and a mobile app; an integration is listed in the Cisco Webex App Hub under the mmhmm Inc. developer name. The company was founded by Phil Libin, founding CEO of Evernote, and emerged from All Turtles, the AI product studio Libin co-founded in 2017.
Founding story
mmhmm was founded in May 2020 by Phil Libin, the founding CEO of Evernote, as an offshoot of All Turtles, the AI product studio Libin co-founded in 2017. Libin has described the project as starting informally, out of an effort to make the team's own experience on video calls more bearable during the shift to remote work, before it developed into a standalone startup.
Business model
Airtime sells its software directly to individual users and teams on a subscription basis, with free trials and a lower-priced or feature-limited free tier historically offered alongside the paid product. Following the 2025 rebrand, the full toolkit is sold as a subscription while the Camera tool is also available as a standalone one-time purchase. The company has also distributed the product through meeting-platform marketplaces such as the Cisco Webex App Hub and offered free education licenses to students and teachers.
Subscription pricing for the full toolkit was $10 per month billed annually or $12 month-to-month at the time of the Airtime launch, with a 14-day free trial and no credit card required at signup. Airtime Camera was made free until August 1, 2025, after which it was to be sold as a standalone app for a one-time fee of $20. Earlier mmhmm pricing was described as roughly $10 per month or $100 per year, with a free/basic tier limiting premium features to 60 minutes a day.
Traction
Publicly disclosed traction is limited. The company reported that hundreds of educators said the product helped create virtual classrooms, prompting a one-year free premium offer to students and teachers, and it had a growing user base on Mac with a Windows version in closed beta as of early 2021. Its website features customer testimonials from users including the CEO of Metaplane and independent creators and trainers.
Latest developments
On April 24, 2025, the company rebranded from mmhmm to Airtime and launched Airtime Camera and Airtime Creator, splitting the original app into separate tools while preserving existing subscriptions and pricing. Airtime Camera was made free to use until August 1, 2025, after which it became a $20 one-time purchase, while the full toolkit remained a subscription. The company has also announced a public API.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
The company operates as a layer on top of established video conferencing platforms rather than as a meeting service itself, positioning its tools as a way to improve presentation quality and on-camera presence in Zoom, Microsoft Teams, Google Meet and Webex calls. Press coverage has noted the risk that its capabilities could be characterized as a feature rather than a standalone product, given its dependence on host meeting platforms.
Rather than offering a single general-purpose application, the company packages specialized tools for distinct goals — live meeting appearance, quick recordings, slide-based presentations and collaborative material review — that interoperate with whichever conferencing service the user already runs. Its presentation approach places the speaker inside the slides so the audience focuses on the presenter, and its interactive recordings can be consumed either as a video or as a deck.
Technology
The product functions as a virtual camera and video mixer that outputs into third-party conferencing applications, with automatic background removal, presenter effects, custom backgrounds and branding, gesture recognition that highlights responses such as thumbs-up in gallery view, and slide import from PowerPoint, Keynote and PDF. It supports live presenting, sectioned recording with editing, high-definition recordings up to one hour, and a Stacks format that imports mixed media into a persistent shared document with real-time attendee presence. The company has announced a public API.
Go-to-market
Distribution is primarily direct, via downloadable Mac and Windows applications, a web app and a mobile app, with self-serve free trials converting to paid subscriptions. The company supplements this with listings in partner marketplaces such as the Cisco Webex App Hub, a sales contact channel for demos, education programs offering a year of free premium access to verified students and teachers, and customer video content featured on its website.
Airtime markets to founders making pitches and company updates, educators building video courses, sales teams delivering demos and customer calls, and distributed or remote teams. Its stated use cases also span online education and training, the creator economy, and enterprise sales. The company has separately offered free premium access to students and educators.
Geography
The company describes itself as a distributed team building for distributed teams. Its software is used with globally available meeting platforms and was offered on Mac, Windows, web and mobile.
History
The company launched in 2020 during the pandemic-driven shift to video meetings, initially with a Mac application. By April 2021 the software was available on Mac and Windows, though not on iPad, and at that point had raised $35.6 million led by Sequoia Capital. In July 2021 it raised $100 million from SoftBank's Vision Fund, Sequoia Capital and others, bringing total funding to approximately $140 million, with plans reported to add a standalone experience and a mobile app. In April 2025 the company rebranded as Airtime and split its functionality into distinct tools, releasing Airtime Camera and Airtime Creator; existing mmhmm desktop users were migrated via an app update that changed the name and icon, and the virtual camera was renamed "Airtime" in meeting software settings.
Risks & controversies
TechCrunch coverage of the company's $100 million raise questioned whether its capabilities constitute a standalone product or a feature of existing video conferencing platforms, and noted uncertainty about demand as virtual meetings became less central after the pandemic. The product's reliance on third-party meeting services such as Zoom, Teams, Meet and Webex creates platform dependency, and educational users have reported that managing the software during a live session requires practice.
