Sidian is the company operating system that gives every team its own Chief Agent, specialist agents, memory, tools, approvals, and an evidence ledger. One chat. One workbench. One auditable system.
The Chief Agent is the only person you talk to. The Chief Agent runs the company. Ask in plain language. The Chief Agent decides which department owns the work, delegates to humans and AI specialists, gathers memory, requests approvals, monitors progress, and produces evidence-cited reports.
You do not pick a tool. You do not write a prompt. You talk to one Chief Agent.
Most AI tools start with a prompt. Sidian starts with a real business intake — the way a chief of staff would onboard a new client. Submit and Sidian generates a complete operating model: departments, agents, policies, approval routes, memory scopes, operating loops.
10 industry packs ship out of the box: one-person startup, local business, SaaS startup, agency, ecommerce, enterprise, regulated finance, healthcare, legal services, professional services. Each pack seeds departments, agents, policies, approval routes, cadences, tool requirements, memory defaults, and knowledge expectations.
Each department is a first-class object: a mission, a manager, members, tools, policies, memory, reports, and a health state. They are not cards on an org chart. They are working teams that the Chief Agent delegates to.
Most AI products wait for a prompt. Sidian runs the company on a schedule. Daily, weekly, monthly, and meeting loops run on autopilot — with explicit autonomy levels and human override.
The Chief Agent is the autopilot. You are the pilot. Most customers run at Level 3 by default. Regulated customers run at Level 1 or 2 with strict approval routes. Founders often run at Level 4 with weekly exception review.
Chat history is not memory. Sidian maintains structured, scoped, permission-aware memory across the company, the department, the agent, and the work run. The Company Knowledge Index tokenizes and indexes every important business surface — without leaking raw content into the model context.
Sidian maintains a continuously updated graph of the company. 31 node kinds, 24 edge kinds, 5 permission modes, 3 risk states, and a replayable event log. The graph powers the cognition engine, the risk engine, the audit engine, the OKR engine, the simulation engine, and the delegation router.
Every high-risk action has a route. Every route has a human. The system is built around the principle that AI drafts, humans decide, evidence is recorded, and rollback is possible.
Sidian is not a generic chatbot. Not just an agent builder. Not just task management. Not just workflow automation. Not just RPA. Not just a BI dashboard. Not a replacement for your CRM, ticketing, finance, or HR system. Not a replacement for your employees. Not a single-vendor lock-in. Sidian is the AI company operating system: one Chief Agent, living departments, governed work, evidence on every action, restore on every mutation.
Real connectors, real credentials, real diagnostics. Sidian ships connectors for code, tickets, email, chat, support, CRM, docs, data, search, identity, and MCP servers. Credentials stay in safeStorage. The renderer never sees a credential value.
Autonomous engineering work mutates files and opens PRs. Sidian takes this seriously. Every approved file mutation is preceded by a Git-backed checkpoint. The restore path enforces 6 hard gates plus 7 audit-policy rules plus 4 trust-lifecycle states.
The Executive Inbox surfaces what needs the human's attention. The Daily Operating Brief summarizes the company. The Plan-of-Plans shows cross-department dependencies. The Live Executive Autopilot runs the cadence in real time.
Sidian is size-aware. The 9-step intake asks for your company size and the operating model scales with you — 5 departments for a solo founder, up to 11 for a 1,000-person enterprise.
5 departments. 1–2 agents per dept. Daily loop. Approval routes for tax filing and invoice sending. One-Person Startup pack. Starter — free.
7 departments. 2–3 agents per dept. Daily + weekly loops. Approval routes for code pushes and customer replies. SaaS, Agency, or Local Business pack.
9–11 departments. 3–7 agents per dept. Daily + weekly + monthly + quarterly loops. All 10 packs. Custom autonomy per department. Business — $59/seat + $19/agent.
11 departments + scaling iterations. Per-environment autonomy. Audit retention. SSO, SCIM, private LLM, on-prem. Dedicated CSM. Custom contract from $50k/yr.
Each pack seeds the operating model with departments, agents, policies, approval routes, cadences, tool requirements, memory defaults, and knowledge expectations. You start from a real operating system, not a blank slate.
Local desktop. Private cloud. Air-gapped. Hybrid. Bring your own model — OpenAI, Anthropic, Azure, Bedrock, vLLM, or a local model. Sidian does not phone home.
Electron app for macOS, Windows, Linux. Dexie + localStorage. safeStorage for credentials. Export and import the full state as JSON.
Sidian server in your VPC. PostgreSQL-backed store. SSO via OIDC, SCIM provisioning. Audit log retention up to 7 years.
Offline desktop deployment. No outbound network traffic. Local model server. Local connector gateway. Tamper-evident audit log.
Desktop app for daily work. Cloud sync for cross-device. Private model gateway for high-risk actions. Public LLM for low-risk actions. Per-actor permission mode.
Policy-checked. Evidence-recorded. Restore-protected. The 7 guarantees below are the contract between Sidian and the CISO.
Sidian is not FedRAMP authorized today. Not SOC 2 Type II audited today. Not a substitute for a HIPAA Business Associate Agreement with a covered entity. The Trust Center lists the current security posture and the roadmap. Sidian is a workforce platform; your security team is responsible for deploying it within your own compliance envelope.
Free for the solo founder. Per-seat for the team. Custom for the enterprise. Provider pass-through at cost + 5% orchestration margin. No bundled markup.
Provider pass-through at cost + 5%. You pay the model provider directly through your own API key. Sidian adds a 5% orchestration margin to cover the provider runtime, event store, and evidence ledger. BYO model: OpenAI, Anthropic, Azure, Bedrock, vLLM, or local.
Sidian customers report the same pattern: fewer meetings, fewer dropped tasks, and repeatable execution. These are representative outcomes from our first pilot cohorts.
“We stopped running the company in Slack threads. Sidian gives every department a Chief Agent that actually knows our context and escalates before things break.”
“The restore console alone paid for the pilot. Our agent made a bad config change and we rolled back in 90 seconds with a full audit trail.”
“We went from ad-hoc ChatGPT prompts to a governed AI workforce in three days. Our legal and finance departments finally trust the outputs.”
Chatbots answer questions. Sidian runs work: it routes requests to department agents, pulls company memory, enforces policies, records evidence, and lets you restore changes. It is an operating system, not a chat window.
No. Sidian uses your existing documents, tickets, and files as a knowledge index and company state graph. Your data stays in your chosen storage — local Dexie, S3, or a private LLM gateway.
Only up to the autonomy threshold you set per department. High-risk actions always route through human approval, and every mutation creates a restore checkpoint first.
You bring your own API key. Sidian works with OpenAI, Anthropic, Azure, AWS Bedrock, vLLM, and local models. You pay the provider directly; Sidian adds a 5% orchestration margin on pass-through tokens.
Yes. Starter is free for one user, one Chief Agent, three departments, and five specialist agents. It is local-first and community-supported. Upgrade when you add seats or need governance.
Most teams set up Sidian in under two hours: install the desktop app, connect a model key, pick department packs, and invite teammates. Enterprise pilots include onboarding from our team.
Free for the solo founder. 30-day pilot for the team. Custom contract for the enterprise.
