Developer Infrastructure for AI Agents

Ship AI agents that humans trust

Two products. One mission. AGR governs every action your agents take. Company Box puts a full engineering team in one person's hands — with you in control of every deploy.

Built for the agent era

AGR gives developers a governance layer they can trust. Company Box gives individuals the output of a full engineering team. Both run on the same infrastructure.

AGR · Developer SDK

Agentic Governance Runtime

A Cedar policy engine that sits between your AI agents and the tools they call. Every action evaluated in under 2ms — formally verified, not probabilistic. Sensitive actions suspend into a Temporal approval workflow until a human decides.

  • Cedar policy engine — formally verified, deterministic. Not an LLM call, not probabilistic.
  • Durable approvals — Temporal workflows suspend indefinitely, consuming zero compute while waiting.
  • Hash-chained audit trail — tamper-proof, partitioned, append-only. SOC 2 ready.
  • Framework plugins — LangGraph @agr_governed, CrewAI AGRToolWrapper, REST API.
  • Multi-tenant RLS — org-scoped policies, zero cross-contamination. Free tier: 10k evals/month.
// 3 lines to govern any agent action
from agr import AGRClient
agr = AGRClient(api_key="agr_sk_...")
result = agr.evaluate(agent, action, resource)

Company Box · SaaS

Your AI engineering team

Type a plain-English requirement. Five AI agents run in sequence — writing spec, architecture, code, tests, and deploying to staging automatically. You approve production. Every agent action governed by AGR at every step.

  • 5-agent pipeline — PM spec → architecture → code → tests → deploy. Claude Sonnet at every step.
  • Real GitHub commits — code lands in your repo, on a branch, as a pull request.
  • E2B sandboxes — code runs in an isolated cloud environment before touching your repo.
  • QA retry loop — failed tests automatically feed back to the Coder agent (max 3 retries).
  • Approval inbox — production deploys need your sign-off. Always. One click, no login.

Who it's for

Three types of builders

From a solo developer governing one agent to infrastructure teams running entire fleets — Shreeja AI meets you where you are.

AGR · Developer SDK

AI infrastructure teams

Teams building internal agent platforms on LangGraph, CrewAI, or AutoGen who need a single governance layer their compliance team can actually audit.

"We needed one governance layer our entire agent fleet could share. AGR gave us Cedar policies, a durable approval gateway, and an audit trail our compliance team actually trusts."
Company Box · SaaS

Solo founders & indie hackers

One-person companies who need to ship features as fast as a funded team — without hiring a single engineer or waiting weeks for a contractor.

"I described a feature on Monday. By Tuesday it was in a PR, tested, staging was live, and I clicked Approve to ship to prod. I didn't write a single line of code."
AGR + Company Box

Startups building on agents

Early-stage teams using LLMs to automate engineering who need auditability and a way for non-technical co-founders to ship independently.

"Our agents were making decisions we couldn't audit. AGR fixed that in an afternoon. Now every action is policy-evaluated and logged with a tamper-proof hash chain."

Audit trail
hash-chained · append-only
ALLOW

Policy permits. Agent executes immediately. Logged to tamper-proof audit trail with policy ID.

DENY

Policy forbids. Agent does not execute. Logged with policy ID and exact deny reason.

APPROVAL_REQUIRED

Temporal workflow suspends. Slack + email sent. Resumes when human decides. Can wait days — consuming zero compute.

// forbid rules — deny by default
forbid (
  principal,
  action == Action::"db.drop",
  resource);

forbid (
  principal,
  action == Action::"fs.write",
  resource == Resource::"prod/*"
) unless {
  principal in Role::"senior-eng"
};
// permit rules — explicit allow
permit (
  principal in Role::"devops",
  action == Action::"deploy.staging",

Integrate in minutes

One decorator. Full governance.

Wrap any LangGraph tool with @agr_governed — zero refactoring of your existing tool code.

# Before AGR — no governance
@tool
def deploy_to_production(branch: str) -> str:
    # runs unconditionally — no policy checks
    return run_deploy(branch)


# After AGR — one decorator, zero refactoring
from agr.plugins.langgraph import agr_governed
from agr import AGRClient

agr = AGRClient(api_key="agr_sk_...")

@agr_governed(agr, agent_id="devops-001")
@tool
def deploy_to_production(branch: str) -> str:
    # Cedar evaluates before every call
    # ALLOW             → executes immediately
    # DENY              → raises PermissionError
    # APPROVAL_REQUIRED → suspends, emails human
    #                     zero compute while waiting
    return run_deploy(branch)

Temporal suspends the workflow entirely. The agent sleeps. You are not billed for waiting.

Platform strategy

Two products, one flywheel

AGR and Company Box reinforce each other. Every Company Box run is a live production test of AGR. Every AGR user is a potential Company Box customer.

Shreeja AI AGR SDK Company Box Developers adopt AGR Founders use CB AGR drives CB CB users → AGR CB hardens AGR devs → CB
1

AGR attracts agent developers

Teams building on LangGraph, CrewAI, and AutoGen need a governance layer their compliance team can audit. AGR is the obvious choice.

2

Company Box is the best AGR demo

CB runs entirely on AGR. It is the most complex consumer of AGR in production. Every CB run is a live end-to-end test of the governance layer.

3

CB users graduate to AGR

When a solo founder hires their first engineer, AGR is the first SDK they reach for. The mental model is already installed.

4

Scale hardens both products

Every CB evaluation stress-tests AGR at scale. Volume reveals edge cases, drives performance, and builds the policy dataset that powers better defaults.
