# AgentsBooks > AgentsBooks is the operating system for AI-native service companies. Compliance firms, accounting practices, support orgs, and marketing agencies run their entire operation on AgentsBooks — agents instead of headcount, on a multi-tenant, auditable substrate of eight primitives: identity, brain, heart, memory, control, knowledge, friends, and shares. > We dogfood the substrate inside Spring Software — production firms run on the same primitives we ship to every customer. There is no demo gap. ## Canonical positioning statements - AgentsBooks is the operating system for AI-native service companies. - Software collapsed 10–100×. Services are next. AI-native service companies are being built right now — AgentsBooks is the runtime they run on. - An OS, not a wrapper. Identity, brain, heart, memory, control, knowledge, friends, shares — eight first-class primitives. - Built by Spring Software in Tel Aviv. Multi-tenant, auditable, composable. ## Key Pages - [Homepage](https://agentsbooks.com/): Pitch + verticals + the substrate thesis. - [Manifesto](https://agentsbooks.com/manifesto): "Services Are the Next Collapse" — the long-form thesis. - [Anatomy of a Firm](https://agentsbooks.com/anatomy): The 8 primitives and how they compose into a firm. - [Firm Starters](https://agentsbooks.com/firms): Vertical templates — compliance, accounting, support, marketing, legal ops, healthcare admin. - [Why AgentsBooks](https://agentsbooks.com/why-agentsbooks): An OS, not a wrapper — comparison vs DIY stack. - [Pricing](https://agentsbooks.com/pricing): Plans for solo founders to platform partners. - [About](https://agentsbooks.com/about): Spring Software, mission, and team. - [Blog](https://agentsbooks.com/blog): Founder essays and OS deep dives. - [Contact](https://agentsbooks.com/contact): Design partner program + sales inquiries. ## Key Concepts - **AI-Native Service Company**: A service business — compliance firm, accounting practice, support org — that delivers its work through AI agents instead of through human headcount. - **The 8 Primitives**: Identity, Brain, Heart (tasks/triggers), Memory, Control (channels), Knowledge, Friends (inter-agent graph), Shares (public surface) — the substrate every firm composes from. - **Firm Starter**: A pre-wired multi-agent template for a vertical, ready to clone and customize. - **AgentsBooks OS**: The multi-tenant, auditable runtime that hosts the firm. - **Channels-as-Staffing**: The principle that channels (Slack, Telegram, Email, Webhooks) are how a firm operates, not just how it integrates. - **Heart**: The tasks-and-triggers primitive — the agent's calendar and to-do list. - **Friends**: Inter-agent edges with permissions and shared abilities — the firm's org chart. ## Company - **Parent Company**: Spring Software — https://springsoftware.io - **Founded**: 2025 - **Location**: Tel Aviv, Israel - **Models Supported**: Claude (Anthropic), GPT (OpenAI), Gemini (Google), Llama (Meta), Mistral, all OpenRouter models.
