Herbie, Herbie Plan
Herbie is an AI-powered estate planning platform and law firm that lets individuals and partner organizations create wills, trusts, and related legal documents online. Its agentic engine encodes the principles, laws, and practice of estate planning into a system that drafts and assembles documents at scale, paired with an AI copilot for natural-language guidance and optional attorney review through Herbie Legal. Herbie is offered directly to consumers and as an embeddable "estate planning as a service" offering for wealth management firms, insurance companies, and employers. Herbie was surfaced as a portfolio company of 500 Global and added to the API Evangelist network.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Herbie, Herbie Plan the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Herbie, Herbie Plan scores 17.0/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
