Outreach is a sales execution platform that automates prospecting sequences, deal management, forecasting, and rep coaching across email, phone, and LinkedIn. Its agentic layer — Outreach Omni, Agent Studio, and task-specific agents — drafts outreach, preps meetings, and flags at-risk deals. Long a category-defining sales-engagement tool for mid-market and enterprise B2B teams.

AI sales agents that learn from your best calls to automate CRM and coaching.

Attention records and transcribes sales conversations, then uses AI agents trained on a team's best calls to auto-update the CRM, draft follow-ups, score reps against coaching scorecards, and surface forecasting and deal insights. It connects to dialers, meeting tools, and CRMs like Salesforce and HubSpot to cut manual data entry across go-to-market workflows.

Vertical AI recruiting platform built around an interview notetaker.

Metaview is an AI platform built specifically for hiring. Its flagship AI notetaker automatically captures and structures interview notes, while companion agents draft job posts, generate hiring reports and analytics, answer questions about candidates, and source profiles. Trained on millions of recruiting conversations, it targets in-house talent teams that want hiring-specific automation rather than a general meeting tool.

Realtime voice AI infrastructure for consumer-facing apps.

Inworld AI builds the infrastructure for production voice AI: a single Realtime API that unifies speech-to-text, an LLM router, and high-quality text-to-speech so developers can ship interactive voice agents, AI companions, and conversational apps at scale.
