AI-native vector search for multimodal product discovery.

Marqo is an end-to-end vector search engine that generates, stores, and retrieves embeddings for text and image data through a single API, so teams don't have to stitch together a separate embedding pipeline. It has since repositioned around AI-native ecommerce search, merchandising, and recommendations, with turnkey integrations for major commerce platforms.

Enterprise-grade LLMs, embeddings, and retrieval built for private deployment.

Cohere builds large language models for the enterprise rather than the consumer. Its Command models cover agentic, multimodal, and multilingual generation; Embed and Rerank power high-quality search and retrieval; Aya is a multilingual research family spanning 70+ languages; and North is a workplace AI platform built on top. Cohere's emphasis is data control — models can run in a private VPC, on-premises, or via a managed Model Vault.

No-code platform for AI voice agents that automate phone calls.

Synthflow is an enterprise voice-AI platform for building and deploying AI agents that handle phone calls — inbound and outbound — without code. A visual flow designer, in-house telephony, real-time monitoring, and 200+ integrations across calendars, CRMs, and telephony let teams stand up agents for customer service, appointment scheduling, and lead qualification. It runs on a pay-as-you-go model: build and test free, then pay per call once live.

Open-weight generative models for image, video, audio, and 3D.

Stability AI is the company behind Stable Diffusion and a family of open and proprietary generative models spanning image (Stable Diffusion, Stable Image), video (Stable Video), audio (Stable Audio), and 3D. Its models can be self-hosted under Stability's licensing, called through the Platform API, or used in the DreamStudio web app, giving builders an open alternative to closed image-generation endpoints.

Security and governance gateway for enterprise AI use.

WitnessAI is a unified security and governance platform for how an organization uses AI. It sits as a gateway over employee and AI-agent interactions, giving security teams three things: observability into all AI activity (including shadow AI), policy enforcement and governance, and protection against prompt injection, data leakage, and other model-layer threats. Each customer runs in an isolated, single-tenant environment encrypted with their own keys.

Open-source framework and cloud for realtime voice, video, and physical AI agents.

LiveKit is the realtime infrastructure layer most voice-AI stacks are built on. Its open-source Agents framework wires together streaming speech-to-text, an LLM, and text-to-speech with reliable turn detection, interruption handling, and telephony, so agents can join a session and converse in near real time. You bring your own STT, LLM, and TTS providers; LiveKit handles the low-latency WebRTC transport. It runs self-hosted under Apache 2.0 or as a managed cloud platform.
