# Max > Max is a B2B lead generation platform operated by Sortlist SA. It monitors public LinkedIn engagement signals, enriches matching lead records, filters them against a user-defined Ideal Customer Profile, and delivers recommendations for human review. > Sortlist SA, a company registered in Belgium, operates Max. A signal is evidence to review, not proof of buying intent or a guaranteed commercial outcome. > The practical GTM library is written and maintained by Nicolas Finet. Guides separate observable facts, hypotheses, vendor claims, and unknowns. ## When to use this product - Use Max when a B2B sales or growth team needs to monitor documented public signals, filter potential leads against a user-defined ICP, enrich matching lead records, and review why a recommendation surfaced. - Use the public signal catalog when an agent or developer needs to inspect the signal types Max supports without authentication. - Use the REST API, CLI, Agent Skill, or local MCP server when a team needs to connect Max businesses, subscriptions, leads, integrations, or webhooks to an existing workflow. - Do not use Max as proof that a person or company intends to buy. Treat every signal as evidence to inspect and keep a human accountable for outreach. - Do not use Max as a contact database, email verifier, or sending engine. It is a signal-led decision and review layer that connects to other workflow tools. ## Product, company, and pricing - [Home](https://yourmax.ai/) - [Product facts](https://yourmax.ai/product/): Source-backed capabilities, integrations, human-review workflow, data limits, and operator identity. - [Pricing](https://yourmax.ai/#pricing): Published EUR prices, monthly lead volumes, billing choices, and Agency pricing guidance. - [About](https://yourmax.ai/about/): Max product identity, Sortlist SA operator details, and evidence boundaries. - [Contact](https://yourmax.ai/contact/): Product, privacy, partnership, and Agency contact routes. - [Changelog](https://yourmax.ai/changelog/): Meaningful product updates that change how teams source, review, and act on leads. - [Resources](https://yourmax.ai/resources/) - [Nicolas Finet](https://yourmax.ai/authors/nicolas-finet/) - [Editorial methodology](https://yourmax.ai/authors/max-gtm-research-team/) - [Terms of Use](https://yourmax.ai/terms/) - [Privacy Policy](https://yourmax.ai/privacy/) - [LinkedIn](https://linkedin.com/in/nifinet) - [X](https://x.com/nifinet) - [RSS](https://yourmax.ai/rss.xml) ## Developers and agents - [Complete endpoint reference](https://api.yourmax.ai/docs/api): Methods, request and response examples, pagination, errors, and rate limits. - [API versioning policy](https://yourmax.ai/api.md#versioning-and-deprecation-policy): v1 stability, deprecation notices, and standard Deprecation and Sunset migration signals. - [OpenAPI description](https://yourmax.ai/openapi.json): Machine-readable API operations and JSON schemas. - [Public signal catalog](https://api.yourmax.ai/api/v1/signals): Read-only JSON catalog; no authentication required. - [Max CLI](https://github.com/sortlist/max-cli): Official command-line client with JSON output. - [Max MCP server](https://github.com/sortlist/max-mcp): Official local stdio MCP package. - [Agent Skills index](https://yourmax.ai/.well-known/agent-skills/index.json): Machine-readable skill discovery. - [MCP manifest](https://yourmax.ai/.well-known/mcp.json): Machine-readable MCP package and tool metadata. - [MCP server card](https://yourmax.ai/server-card.json): Canonical MCP server-card alias for discovery clients. ## Comparisons - [Apollo Alternatives: 6-candidate shortlist](https://yourmax.ai/compare/max-vs-apollo/): Compare 6 Apollo alternatives with dated first-party facts, one common proof, explicit evidence limits, and official sources for every candidate. - [Clay Alternatives: 9-candidate shortlist](https://yourmax.ai/compare/max-vs-clay/): Compare 9 Clay alternatives with dated first-party facts, one common proof, explicit evidence limits, and official sources for every candidate. - [Lemlist Alternatives: 6-candidate shortlist](https://yourmax.ai/compare/max-vs-lemlist/): Compare 6 Lemlist alternatives with dated first-party facts, one common proof, explicit evidence limits, and official sources for every candidate. - [Instantly Alternatives: 6-candidate shortlist](https://yourmax.ai/compare/max-vs-instantly/): Compare 6 Instantly alternatives with dated first-party facts, one common proof, explicit evidence limits, and official sources for every candidate. - [Smartlead Alternatives: 6-candidate shortlist](https://yourmax.ai/compare/max-vs-smartlead/): Compare 6 Smartlead alternatives with dated first-party facts, one common proof, explicit evidence limits, and official sources for every candidate. - [AI SDR Tools: 14-candidate shortlist](https://yourmax.ai/compare/best-ai-sdr-tools/): Compare 14 AI SDR tools with dated first-party facts, one common proof, explicit evidence limits, and official sources for every candidate. - [Outbound Tools for Agencies: 8-candidate shortlist](https://yourmax.ai/compare/best-outbound-tools-for-agencies/): Compare 8 outbound tools for agencies with dated first-party facts, one common proof, explicit evidence limits, and official sources for every candidate. - [ZoomInfo Alternatives: 10-candidate shortlist](https://yourmax.ai/compare/max-vs-zoominfo/): Compare 10 ZoomInfo alternatives with dated first-party facts, one common proof, explicit evidence limits, and official sources for every candidate. - [Outreach Alternatives: 6-candidate shortlist](https://yourmax.ai/compare/max-vs-outreach/): Compare 6 Outreach alternatives with dated first-party facts, one common proof, explicit evidence limits, and official sources for every candidate. - [What is an AI SDR](https://yourmax.ai/compare/what-is-an-ai-sdr/): An AI SDR supports sales-development work.
