Pre-Execution Governance

Govern agent execution before it happens.

Fulcrum is the governance kernel for autonomous AI. Sub-millisecond policy enforcement. Formally verified safety invariants. Pre-execution — not post-mortem.

Monitoring tells you what broke. Governance decides what runs.

Most products observe behavior after actions are in motion. Fulcrum sits in the execution path and routes actions before they commit.

The Thank-You Note

AutoGen agents stuck in a gratitude loop overnight, burning budget with no governance check.

17.2×

Error Amplification

Google DeepMind found multi-agent cascades amplify errors by 17.2× without upstream control.

53%

Insecure MCP Servers

Astrix/Backslash research found 53% of MCP servers have protocol-level security exposure.

A classifier that says "99% safe" is not safe.

It's a prediction with a 1% error rate across millions of transactions.

We don't estimate safety. We prove it.

Probabilistic

{ confidence: 0.993, safe: true }

Across 1M transactions, this produces ~7,000 unverified actions.

Provable (Fulcrum)

theorem budget_safety :
∀ (k : BudgetKey), spend k ≤ limit k
-- Verified. Zero exceptions.

Machine-checkable certificate. Zero unverified actions.

Seven lines to govern your first agent.

agent.py

from fulcrum_trust import TrustManager

manager = TrustManager(threshold=0.3)
result = manager.evaluate(
    pair_id="agent-1",
    outcome=SUCCESS
)
if result.should_terminate:
    agent.stop()

Works with LangGraph, AutoGen, CrewAI. No agent rewrites. No SDK migration.

August 2, 2026. The EU AI Act enforcement deadline.

Fulcrum maps governance capabilities to regulatory requirements, turning compliance from a manual burden into a verifiable pipeline.

Regulation	Deadline	Fulcrum Capability
EU AI Act (High-Risk)	Aug 2, 2026	Formal proof certificates for conformity assessment
Colorado SB 24-205	Feb 1, 2026	"Reasonable care" via machine-checkable proofs
MAS AIRG (Singapore)	2026	Third-party vendor governance via MCP proxy
SOX Section 302	Ongoing	Budget Safety Invariant for financial controls

From free governance to provable safety.
