Deepgram pairs a real diarization quality jump with voice-agent platform breadth.
Deepgram is shipping on two tracks at once. The speech-recognition core is getting model-quality work — diarization v2 is the headline, with profanity filtering and numerals expanding across long tails of languages. In parallel, the Voice Agent API is being built out as a multi-vendor orchestration layer, with managed Gemini, GPT, and Cartesia options sitting next to Deepgram's own Aura-2 TTS and Flux ASR.
Heymarket evolves from team SMS into an AI-agent messaging platform.
Heymarket has shipped a string of real product features — Escalations, inbound webhooks, Conversation Tags, Salesforce/HubSpot email — and is now publicly building AI agents that handle customer messaging, with the team using its own product as the first deployment site. The platform is moving past 'business texting' into multichannel customer messaging with structured workflows and automation primitives.

In parallel, the Voice Agent API is being built out as a multi-vendor orchestration layer, with managed Gemini, GPT, and Cartesia options sitting next to Deepgram's own Aura-2 TTS and Flux ASR.
The arc is two products converging: a best-in-class speech stack and an opinionated voice-agent runtime that abstracts the LLM/TTS choice. Diarization v2 — preferred 3.3× over v1 in human eval, with ~80% median CER reduction on contact-center audio — is the kind of underlying model win that pulls call-center workloads onto the platform. Meanwhile, runtime controls like Aura-2 speed and pronunciation, plus managed third-party LLMs, position Deepgram as a single integration target rather than a single component vendor.
Expect Diarization v2 to become the default behind diarize=true once the opt-in window closes, and expect the Voice Agent API to keep adding tier-priced managed providers — that's the obvious monetization layer. Multilingual feature parity (numerals, profanity, Flux) will continue to fill in tail languages, narrowing the gap between English-only buyers and global deployments.

Each release stacks toward a coherent thesis: omnichannel inbox plus tagging plus escalation routing plus webhooks adds up to the platform substrate an AI agent needs. The 'eating our own dogfood' post on AI agents confirms agents are now in production internally, which is a stronger signal than a marketing launch. Heymarket is positioning to be where SMBs run customer messaging end-to-end, with humans handling exceptions the agents escalate.
Expect a public-facing AI agents launch in the next quarter — likely a packaged product with deflection rate or response-time SLAs as the headline metric. Pricing change toward usage-based components (per-resolution or per-conversation) would be the natural follow-on as agent costs become the dominant unit economics question.
