Company profile

researched Aug 2026

Naïve is an infrastructure platform for building, deploying and operating AI agents and agent-built applications. Its stack provisions per-agent cloud services — Postgres, authentication, object storage, realtime sync, edge functions, queues and cron — through a single command ("naive up"), alongside hosting for fullstack apps, serverless functions and GPU workloads on managed compute and sandboxed containers.

Beyond the application backend, the platform gives agents a real-world operating presence: KYC/KYB verification, US LLC and EIN incorporation, registered agent services, email inboxes, domains, DNS and phone/SMS numbers, plus distribution to social channels and search. Money movement runs through scoped virtual cards with hard spend limits enforced at card authorization, together with invoicing so operators can bill their own customers. A governance control plane sits in front of every primitive, offering audit logging and replay, capability allow/deny lists per agent and per end-user, session-scoped MCP tool access, human-in-the-loop approval policies for sensitive actions, and mid-flight revocation of cards, sessions and capabilities.

Agents and multi-agent teams are declared as infrastructure-as-code via the @usenaive-sdk/iac package, where identity, permissions, budgets and coordination edges are versioned in the repository. Teams run on Vetta, a durable runtime supporting a lead agent with a typed roster and state that survives crashes, or on Hermes. A model router exposes 300+ models through one API with task-based routing, automatic fallbacks and exact-cost metering, and the platform connects to 100+ third-party tools including Stripe, Supabase, Vercel, QuickBooks, PostHog, Mercury, Rippling, Brave Search and Instantly.

Business model

Naïve sells developer infrastructure delivered as a hosted platform and SDK/CLI, bundling compute, database, identity, payments and model routing primitives behind a single API key and configuration file.

▸Full profile — market position, technology, go-to-market

Market position

Positions itself as agent-native cloud and financial infrastructure, interoperating with incumbent developer tools such as Stripe, Supabase, Vercel and QuickBooks rather than replacing them, and serving as the primitive layer called by coding agents like Codex, Claude Code and Cursor.

The platform combines agent application infrastructure with real-world capabilities most backends omit — business identity and US incorporation, spend-capped virtual cards enforced at authorization rather than post-hoc alerts, and policy governance applied to every primitive — all declared in a single versioned config file rather than chained API calls.

Technology

Declarative infrastructure-as-code for agents (@usenaive-sdk/iac) defining identity, skills, budgets and approval rules; per-agent provisioning of Postgres, auth, object storage, realtime, edge functions, queues and cron; microVM-based hosting for fullstack apps, serverless functions and GPU workloads; the Vetta durable multi-agent runtime and the Hermes runtime; a model router covering 300+ models with task routing, fallback chains and exact-cost metering; and a policy control plane with audit logs, capability scoping, HITL approvals and revocation.

Go-to-market

Self-serve developer adoption through a CLI and copyable setup prompt that can be dropped into any coding agent, supported by a primitives directory and prebuilt templates for use cases such as an AI SEO platform, an autonomous company, a fullstack SaaS builder, mobile-use agents, an accounting agent and a recruiting agent.

Developers and teams building AI agents, agent-operated applications and multi-agent systems, including users of coding agents such as Codex, Claude Code and Cursor that call the platform's primitives.
