Comparison
AI agents can research accounts, use tools, call APIs, and automate multi-step work. A team building its own sales-intelligence system still has to define what to watch, preserve evidence and history, manage permissions, evaluate results, and keep the workflow reliable. Kaiju packages that account model as a product.

Kaiju may fit when
Choose Kaiju when you want agents and sellers to start from a maintained account history with signals, people, working lists, priority, and evidence already organized.
AI agents may fit when
Build with agents when your team wants full control over the research and automation system and is prepared to own its data model, evaluation, permissions, reliability, and maintenance.
Use both when
Agents can consume Kaiju intelligence and perform downstream work once Kaiju exposes the appropriate tool, API, or MCP surface. That keeps domain state durable while agents remain flexible execution clients.
Decision table
Kaiju
A maintained sales-intelligence model with account evidence, signal definitions and occurrences, filters, Dynamic Lists, priority, people, actions, and shared history.
AI agents
Agent frameworks provide model access, instructions, tools, handoffs, guardrails, tracing, memory, MCP connectivity, sandboxes, and orchestration primitives for you to compose.
Kaiju
Research feeds a durable account record with provenance, timestamps, coverage, conflicts, unknowns, and seller-neutral facts before sales interpretation.
AI agents
An agent can browse, search files, call internal tools, inspect systems, and synthesize an answer; the application must decide which outputs become durable records and how they are normalized.
Kaiju
Signal definitions are versioned sales semantics; occurrences have evidence, time, state, freshness, and lifecycle separate from filters and list membership.
AI agents
A custom agent system needs its own definitions, event history, temporal rules, deduplication, state transitions, expiration policy, and evaluation if those properties matter.
Kaiju
Dynamic Lists maintain explainable membership over a defined candidate universe as facts and signals change.
AI agents
Agents can query or construct account sets, while the surrounding application must persist membership, refresh rules, provenance, and change history when those sets need to survive individual runs.
Kaiju
Kaiju owns the product contracts for evidence, signals, list state, account projections, and integrations as the platform matures.
AI agents
The builder owns tool permissions, prompt-injection defenses, credential isolation, traces, evals, retries, checkpoints, model changes, deployment, and operational maintenance.
Kaiju
Kaiju can become the durable intelligence layer an agent reads before deciding or acting.
AI agents
The agent remains useful for flexible reasoning, research tasks, drafting, and execution across tools without becoming the sole system of record for account intelligence.

Analytics preferences
Analytics helps Kaiju understand which pages and actions are useful. Marketing tracking can identify business visitors for follow-up. Essential storage remains available either way.
