One intent. The agent runs the whole journey.

A client developer reads the docs and hand-codes this sequence today. With Buildd, the agent plans it, passes state between steps, enforces gates, retries safely, and pauses for human approval where it matters — origination to disbursal, end-to-end.

Bank-grade trust, built into every agent

Autonomy is only adoptable when it is governed. Buildd wraps every agent action in the controls regulated institutions require — so Banks, Wealth Managers and Insurers can ship with confidence.

Mechanical governance gates

High-stakes actions — credit approval, disbursal, rejection, high-value mandates — pass through hard policy gates the model cannot talk its way past.

Guardrails & red-teaming

A policy surface constrains agent behavior, continuously evaluated against prompt-injection and jailbreak attempts before anything ships.

Fair & explainable credit

Bureau-driven decisions are checked for demographic-parity and equal-opportunity gaps, and every decision carries an explanation.

Fraud & AML monitoring

Transaction-graph analysis flags laundering rings and anomalies across payment and disbursal flows in real time.

Vendor-neutral models

Bring your own LLM — OpenAI-compatible, internal gateway, or on-prem. Banks keep full control of the model layer.

Regulator-grade audit trail

An append-only record of every agent intent, plan step, gate decision, approver, and outcome — traceable end-to-end.
