In their own words
Forest Admin
Forest Admin is an operational backend that connects operations teams and AI agents with databases, compliance suppliers, and workflows. It presents use cases including KYC onboarding, KYB/UBO, requests for information, transaction monitoring, and dispute handling. Forest says it reads and writes directly to databases and APIs without an ETL or copy layer, with the backend deployed in the customer's infrastructure. Workflow tools include case inboxes, dispatch rules, SLAs, multi-step workflows, approvals, escalations, and human review gates. Human users and AI agents share role-based permissions; record-level audit logs can include agent reasoning traces. Listed connectors include PostgreSQL, MongoDB, BigQuery, Snowflake, REST APIs, and GraphQL APIs. The integrations page names Adyen for triggering refunds, holds, reversals, and dispute responses. Forest lists SOC 2, HIPAA, PSD3, GDPR, and the EU AI Act in its compliance section. Pricing includes a free Sandbox, Starter at $499 a month, Professional at $2,199 a month, and Enterprise from $5,999 a month with an annual upfront payment discount. A free 30-day trial is also available.
