Company profile

researched Aug 2026

C1 (c1.ai) positions itself as a universal control plane for identity and access in what it calls the "agentic enterprise," covering employees, contractors, OAuth tokens, API keys, and AI agents. The company's stated aim is to make every identity visible as soon as it is created and to hold it to least-privilege access in real time, replacing manual processes with policy-driven automation across an organization's systems.

The product set described on the company site comprises four components: the Identity Security Platform (an AI-native identity security layer with a unified directory plus built-in security and compliance automation); the AI Access Gateway (an identity-aware gateway applying policy and data controls to agent actions); the Agentic Vault (a post-quantum vault for agent credentialing and service accounts); and C1 Autonomous Worker (C1AW), AI agents that automate work under enforced access controls. C1 markets use cases spanning shadow AI discovery, credential security, agent runtime governance, agentic security and intelligence, and AI-native identity governance, and claims capabilities including just-in-time access controls, self-service access across apps and MCP servers, real-time detection and remediation of security issues, and fully audited tool-call coverage.

The company also runs an engineering blog covering identity infrastructure and security architecture topics such as Postgres query planning, DynamoDB partition-key sharding, embedding pipeline cost reduction, connection authentication for "C1 Bridge," formal-methods work on permission derivations and connector branch conditions, and the evolution of its AI agent loop into the c1aw governed loop. C1 is hosting a customer and industry conference, C1 Transform 2026, on October 6, 2026 at The Clancy in San Francisco. [0][1][3][5]

Business model

C1 sells an enterprise software platform for identity security and access automation, marketed through demo requests and an "explore the platform" motion on its website; the sources do not disclose pricing or contract structure. [0][1]

Traction

Public evidence of traction is limited to customer testimonials on the company website, including named individuals from DigitalOcean and a reference to Zscaler, plus the scheduling of a customer conference in San Francisco for October 2026. No revenue, customer count, or headcount figures appear in the sources. [0][1][5]

Latest developments

C1 announced C1 Transform 2026, a conference set for October 6, 2026 at The Clancy in San Francisco, with a room block at $429/night and a speaker roster drawn from Cursor, Together AI, Brex, Vanta, Daytona.io, DraftKings, and a former Okta chief product architect. The engineering blog published posts through August 2026, including a Postgres query-planning issue with a patch submitted to pgsql-hackers and a description of connection authentication for C1 Bridge.

Full profile — market position, technology, go-to-market, geography, risks & controversies

Market position

C1 markets itself as a control plane spanning human, workload, and agent identities, and cites a 2026 Future of Identity Report claiming 95% of organizations already run autonomous AI agents, 47% say non-human identities outnumber people, and only 22% have full visibility into those identities. The sources do not contain independent market share or analyst positioning data. [0][1]

Stated differentiators are unified coverage of human, non-human, and AI agent identities in a single platform; runtime governance of agent actions with 100% audited tool-call coverage; a post-quantum vault for agent credentials; and breadth of connectivity claimed at 300+ app connectors and 3,000+ MCPs out of the box, with integrations to systems including Okta, AWS, Salesforce, Slack, GitHub, Snowflake, Azure, Google Workspace, Microsoft Entra, ServiceNow, and Cursor. [0][1]

Technology

C1 describes an AI-native platform with a unified identity directory, an identity-aware gateway for AI and MCP traffic, a post-quantum credential vault, and AI agents (C1AW) operating under access controls. Public engineering posts describe underlying infrastructure work including PostgreSQL query planning fixes, calculated partition-key sharding on DynamoDB via protoc-gen-dynamo, an embedding pipeline refactor cutting Bedrock inference costs and vector storage roughly in half, keepalive-based connection authentication in C1 Bridge for long-lived private-network connections, an agent-TUI tool that exposes rendered terminal screens to agents, and formal-methods techniques such as fault injection, e-graph equivalence proofs for permission derivations, and compiling connector branch conditions to deterministic finite automata. [0][1][3]

Go-to-market

Direct enterprise sales supported by website demo requests, published customer stories, integrations and MCP directories, and a company-hosted conference (C1 Transform 2026) aimed at security and AI strategy leaders, with speakers from Cursor, Together AI, Brex, Vanta, Daytona.io, DraftKings, and a former Okta chief product architect. [0][1][5]

Large enterprises adopting AI and agentic systems, with buyers in security, IT, and infrastructure functions. Named customer voices on the site include a Director of Product and Infrastructure Security at DigitalOcean, a CISO, a Director of IT, an Infrastructure Security Team Leader, and a Director of Corporate Applications referencing Zscaler. [0][1]

Geography

The C1 Transform 2026 conference is being held in San Francisco, California; the sources provide no further detail on office locations or international presence. [5]
