Enterprise text-to-speech built for real-time voice agents.

Rime builds AI voice models for high-stakes business conversations like IVRs, contact centers, and AI phone agents. Its Arcana and Mist models target ultra-low latency and natural, conversational delivery, with deterministic pronunciation control so terms are spoken consistently without retraining. Rime can be deployed on-prem, in a VPC, or via cloud API, and is offered directly or through voice-AI partner platforms.

An AI platform for end-to-end video production.

LTX Studio is Lightricks' AI filmmaking suite that turns a script or prompt into characters, storyboards, and edited video sequences. It pairs generation (text-to-video, image-to-video, video-to-video) with director-style controls — camera framing, keyframe animation, character consistency, and a timeline editor — so creators can shape a full production, not just one clip. It runs on Lightricks' own LTX models and also integrates third-party models for generation and audio.

Open-source MCP integrations and live environments for AI agents.

Klavis AI is an open-source layer of Model Context Protocol (MCP) servers and clients that lets AI agents reliably use external tools like GitHub, Gmail, Google Sheets, Jira, and Slack. It handles OAuth and multi-tenant auth, ships hosted servers plus self-hostable images, and has expanded into managed sandbox environments for training and evaluating long-horizon agents. Teams can call the hosted endpoints or run the open-source servers on their own infra.

Deploy apps, databases, and AI/GPU workloads on any cloud.

Northflank is a developer platform for deploying applications, databases, jobs, and AI/GPU workloads from Git to production. It abstracts away Kubernetes and runs on Northflank's managed cloud or in your own AWS, GCP, Azure, or bare-metal account (BYOC), billed by the second. Teams like Writer, Sentry, and Chai Discovery run on it.

AI roleplay games set in your favorite story worlds.

Hidden Door is a social AI storytelling platform where players roleplay collaborative adventures guided by an AI Narrator, presented as interactive graphic novels. It launched with public-domain worlds like Pride and Prejudice, The Call of Cthulhu, and The Wizard of Oz, and licenses IP through revenue-share with creators rather than training on their work without permission. Every playthrough differs because choices reshape the story.

A generative behavior engine for living game characters.

Artificial Agency's behavior engine uses foundation models to turn game systems into autonomous agents at runtime — characters that remember player interactions and personalize encounters, plus 'game director' systems that adapt story and pacing. Studios integrate it into any genre without game-specific training, keeping their existing tools and workflows. The engine launched in alpha to select studios via a pilot program.

No-code AI robotic arms built for US manufacturing.

Standard Bots makes the Core (formerly RO1), a six-axis collaborative robot arm programmed through no-code software — drag, tap, and teach, with no engineers required. A transformer-based model lets the arm learn intricate tasks by human demonstration, targeting CNC machine tending, palletizing, welding, and pick-and-place. The arms are designed and built in the US.

One pay-as-you-go API for 400K+ image, video, audio, and 3D models.

Runware is a unified AI inference platform that exposes 400K+ models — image, video, audio, text, and 3D — behind a single pay-as-you-go API. It runs a proprietary Sonic Inference Engine on custom GPU hardware, claiming sub-second cold starts and up to 10x lower cost per generation than typical hosted inference. A REST and WebSocket API plus a web playground let developers swap models without per-provider integrations.

AI localization for 300+ languages — text, audio, and video.

Algebras AI is an AI localization platform that translates UI strings, documents, audio, and video into 300+ languages and over 1,000 dialects with minimal proofreading. It offers real-time dubbing, adaptive subtitles, lip-synced video translation, glossaries, and QA checks, with integrations for Next.js, Unity, Unreal, GitHub Actions, and Zapier. An open-source CLI and API let teams wire localization into their build pipeline.

Open-source observability and evals for AI agents.

Latitude is an open-source monitoring platform for AI agents in production. It captures agent-native traces across multi-turn sessions, tool calls, and full execution paths, then clusters failures into tracked issues and alerts via Slack, email, or webhooks. It is OpenTelemetry-native, supports semantic search over sessions, and auto-builds evals from your team's judgments — run it as managed cloud or self-host the whole stack.

Self-driving observability, evals, and an AI gateway for LLM agents.

Respan is a unified LLM-engineering platform that routes, observes, and evaluates every model call from one control plane. Its AI gateway fronts 500+ models with fallbacks, load balancing, and spend caps; trace trees, dashboards, and alerts cover observability; and rule checks, AI judges, and human review run as one evaluation workflow. An automated eval agent surfaces issues from production traffic so teams can fix what breaks without stitching tools together.

AI hiring platform for assessments and video interviews.

HireVue is an enterprise hiring platform that uses AI to screen and validate candidate skills through video interviews, game-based and technical assessments, and an AI Interviewer. It adds candidate matching, scheduling, and workflow automation, with deep ATS integrations. Widely used for high-volume and structured hiring.

AI talent intelligence for sourcing, hiring, and planning.

Findem is an AI talent-intelligence platform that builds enriched candidate profiles — its '3D data' attributes — from across the web to power sourcing, talent marketing, and analytics. Its agentic layer adds screening, scheduling, and job-post agents. Aimed at talent-acquisition teams hiring and planning beyond what a résumé shows.

AI revenue orchestration for sales engagement and forecasting.

Salesloft is an AI revenue-orchestration platform combining sales engagement (Cadence), conversation intelligence, deal management, and forecasting.

A long-standing category leader for mid-market and enterprise revenue teams.

Agentic AI platform for sales and revenue teams.

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.
