Daily, which offers APIs for developers to add video and audio features to apps and websites, raises a $40M Series B, bringing its total funding to $60M
Context & Ripple Effects
Daily's $40M Series B lands it in the middle of a funding pattern that has been building for years: developers embedding real-time communication rather than building it. Agora set the template back in 2018 with an expanded Series B to fund global expansion of its voice and video APIs, and Stream followed in March 2021 with a $38M Series B for embeddable chat and activity streams — Daily's round is the same thesis applied to video and audio.
What makes the round notable is that the category is still attracting capital at every stage: months after Daily's raise, India-based 100ms pulled in a $20M Series A for video conferencing APIs, and AssemblyAI raised for audio transcription and moderation APIs — evidence that investors see room for multiple winners across the stack.
First-order effects
- Daily now has $60M in total funding to scale its video and audio APIs, directly competing for the same developer mindshare Agora has courted since its 2018 expansion round.
- Developers building apps get a better-capitalized alternative to rolling their own WebRTC infrastructure or defaulting to Agora.
Second-order effects
- Agora and newer entrants like 100ms face pressure to differentiate on pricing and reliability as well-funded API rivals multiply, while Stream's chat APIs and AssemblyAI's audio-transcription APIs show buyers can now assemble full communication stacks from specialist vendors.
- The capital inflow pushes these vendors toward platform breadth — bundling video, audio, chat, and transcription — to lock developers in before a competitor owns the whole workflow.
Third-order effects
- If the funding cadence holds, real-time communication consolidates into an infrastructure layer where video, audio, chat, and speech AI are purchased as APIs from competing platforms — reshaping which startups get acquired and which become the default plumbing for the next generation of apps.
- The pattern also suggests a maturing market where differentiation shifts from raw API capability to developer experience and geographic reach, favoring vendors that expand internationally early, as Agora did.
The trend: Real-time communication is becoming a buy-not-build API market, with venture capital funding a wave of specialist vendors — Daily, Agora, 100ms, AssemblyAI — competing to be the default layer for video, audio, and chat inside third-party apps.
