# DealLayer > Agent-first private-market discovery for investors, founders, and their AI agents. ## About DealLayer is a structured discovery layer for private-market listings. The public surface is factual, public-tier only, and designed to be safely cited by search engines and AI assistants. ## Public data boundary - Public pages, REST endpoints, and MCP read tools expose only public-tier listing fields. - Private diligence files, unpublished founder details, and gated financial material are not part of the anonymous public surface. - DealLayer is an information and discovery product, not investment advice or a securities offering. ## Citation guidance - Cite Marketplace, company profile, glossary, docs, and pricing routes when summarising DealLayer publicly. - Use company profile pages for company-specific factual summaries and glossary/docs pages for product-model explanations. - Do not imply access to private diligence, confidential documents, or non-public founder information unless explicitly provided outside the public surface. ## Topics we cover - [Private-market marketplace](/marketplace) Public discovery surface for live listings - [Glossary](/glossary) Definitions and reference notes for agent-first private-market discovery - [MCP and API documentation](/docs) Product and integration documentation - [Pricing](/pricing) Commercial model and launch posture ## Key resources - [Marketplace](/marketplace) - [Glossary](/glossary) - [Docs](/docs) - [MCP tools reference](/docs/mcp-tools) - [Terms](/terms) ## Core glossary concepts ### [What is agent-first private-market discovery?](/glossary/agent-first-private-market-discovery) Agent-first private-market discovery means company data is published in a structure that AI agents can search, compare, and cite directly instead of scraping narrative decks or cold outreach. ### [How MCP fits private-market discovery](/glossary/mcp-for-private-market-discovery) MCP gives AI clients a standard way to call tools such as company search and profile retrieval, which is why it matters for structured private-market discovery platforms. ### [Public vs gated listing data](/glossary/public-vs-gated-listing-data) Public listing data is the factual, indexable surface that can be safely browsed and cited, while gated data covers richer investor or diligence material that should not appear in search or public schemas. ## Recent public listings ### [Lumen Health](/co/lumen-health) Clinical decision support for NHS mental health trusts. ### [Saltmarsh Agritech](/co/saltmarsh-ag) Soil carbon measurement for regenerative farms, satellite + soil sensor fusion. ### [Pylon Grid](/co/pylon-grid) Grid-flex trading for domestic battery fleets. ### [Orbit Legal](/co/orbit-legal) Contract review that works at the speed of your inbox. ### [Quorum](/co/quorum-dao) Corporate governance tooling for distributed leadership teams. ### [Nimbus.ai](/co/nimbus-ai) Agent-native observability for production AI systems. ### [Stackform](/co/stackform) Infra-as-prompt: describe your stack, Stackform provisions it. ### [Wavetable](/co/wavetable) AI stem-separation + remix tools for independent producers.
