What Multi does

Multi (formerly Remotion) was a multiplayer collaboration platform built natively for macOS, enabling software development teams to work together on shared applications in real time. Founded in 2021 and headquartered in San Francisco, the company developed a single-product SaaS offering distinguished by its native Swift/AppKit architecture (rather than Electron) and WebRTC peer-to-peer shared control with sub-100ms latency. The product supported up to 10 simultaneous screen shares, multicursor interaction, AI-generated meeting summaries, session recording, and integrations with developer tools such as Linear, Raycast, and Google Calendar. Target users were software engineering and design teams working in pair programming, code reviews, bug bashing, and remote standups.

The company's technology stack relied on Zoom Video SDK for audio/video infrastructure, Google Cloud Platform (including Firebase) for authentication and storage, and third-party AI APIs from OpenAI and Anthropic for transcription summarization. Distribution was product-led growth (PLG) via direct download of the native macOS app from multi.app, complemented by an enterprise sales motion and a Google Workspace Marketplace listing for the Google Calendar add-on. Marketing was driven primarily through engineering blog content, Product Hunt launches, and organic word-of-mouth within developer communities.

Multi operated independently from founding until June 24, 2024, when the company announced it was joining OpenAI, with the service subsequently sunset on July 24, 2024 and all user data deleted. Prior to acquisition, Multi had raised approximately $13 million across a $2.6M Seed (December 2019, led by First Round Capital) and a $10.4M Series A (October 2020, led by Greylock). The company did not publicly disclose pricing, revenue, or detailed customer metrics.

Partnerships

Eight partnerships are on record, tiered flagship and core.

• OpenAIflagshipStrategic or Co-development Partner · 24 June 2024Multi announced it was joining OpenAI on June 24, 2024. The Multi team joined OpenAI to work on the intersection of AI and human-computer collaboration. As a result, Multi sunset its product and shut down on July 24, 2024, with all user data deleted. This was a full acquisition/team acquisition, not a commercial partnership.
• ZoomcoreTechnology or IntegrationMulti used Zoom as its sole vendor for audio, video, data transmission, and recording for all call data streams including screen share and text chat. Zoom provides 256-bit AES-GCM encryption for streams in transit. Multi utilized Zoom Cloud Transcriptions for AI summaries and Zoom's cloud call recording. Multi switched from Twilio/Agora infrastructure to Zoom Video SDK in January 2023 for world-class infrastructure.
• Google Cloud PlatformcoreTechnology or IntegrationMulti used Google Cloud Platform, including Firebase, for user authentication, user data storage, application distribution, and server-side functions. All data encrypted in transit via HTTPS TLS 1.2 and stored under AES-256. Multi also used Google Analytics, BigQuery for analytics, and Google Tag Manager.
• OpenAIcoreTechnology or IntegrationMulti used OpenAI APIs for AI processing of transcriptions to generate AI summaries. Raw transcription data was sent only to OpenAI and Anthropic APIs and never to analytics services or client devices. OpenAI and Anthropic adhere to a 30-day data retention policy and do not use Multi customer data to train their models.
• AnthropiccoreTechnology or IntegrationMulti used Anthropic APIs as an additional AI processing provider for generating AI summaries from call transcriptions. Anthropic adheres to a 30-day data retention policy and does not use Multi customer data to train models.
• LinearcoreTechnology or IntegrationMulti had deep integration with Linear, a project management tool popular among software teams. Users could push action items captured in Multi sessions directly to Linear with one click. Multi also supported deep links for Linear in shared control.
• RaycastcoreTechnology or IntegrationMulti published a Raycast Extension allowing Raycast users to perform core Multi actions (call a teammate, join a room, control devices) directly from the Raycast launcher. Built on newly-exposed AppleScript Commands. Raycast's design philosophy (keyboard-first, extendable launcher) influenced Multi's own design approach.
• Google CalendarcoreTechnology or IntegrationMulti offered a Google Calendar integration via a Multi add-on in the Google Workspace Marketplace. Users could add a Multi Session link to any Google Calendar event with a single click, or configure automatic linking. The integration enabled seamless scheduling of multiplayer collaboration sessions.

Broad incumbents

• Zoom Video Communications: Zoom is the dominant video conferencing platform serving the same developer/team use cases (screen share, recording, AI summaries). Multi itself used Zoom's Video SDK for AV infrastructure, and Zoom Meetings is the broad incumbent Multi competed against for end-user collaboration.
• Slack (Slack Huddles): Slack's Huddles feature provides lightweight voice/video collaboration embedded in persistent team chat, overlapping Multi's intent to replace meetings with always-available multiplayer collaboration for developer teams.
• Microsoft Teams: Microsoft Teams bundles video calling, chat, file collaboration and AI meeting summaries for enterprise teams. It competes with Multi on the unified collaboration experience for software and business teams, especially in enterprise IT-environments.
• Notion: Notion's multiplayer workspace/notepad and AI features overlap with Multi's collaborative notepad and AI summaries, and it serves a similar horizontal knowledge-worker audience with deep team retention.
• Google Meet: Google Meet is the broad-incumbent video calling product integrated with Google Workspace (Calendar, Drive). Multi targeted the same collaboration moments via Calendar integration and Zoom-equivalent AV, and Meet represents the dominant free / SMB alternative.

Emerging players

• Discord: Discord's persistent voice rooms and screen share are increasingly used by software/dev teams for informal collaboration, partially overlapping Multi's "always-on multiplayer" thesis for technical teams.
• Whereby: Whereby is a browser-based video meeting tool aimed at lightweight team calls and embedded collaboration, overlapping Multi on frictionless team video and screen sharing for small software/dev teams.
• Pop.com (Pop): Pop is a lightweight asynchronous screen sharing/recording tool for fast visual updates, competing with Multi's screen share, drawing annotation, and recording capabilities from the async-collaboration angle.

Direct peers

• Tuple: Tuple is a dedicated mac-native pair programming screen sharing tool for software developers, offering low-latency shared control and audio. It competes most directly with Multi's shared control, sub-100ms latency, and developer-team positioning on macOS.
• Around: Around is a lightweight, low-friction video collaboration tool focused on async and synchronous team huddles. It overlaps Multi on small-team video collaboration, transcription/summaries, and developer-friendly UX, and was itself acquired by Atlassian in 2022.
