The Engine

AI is the infrastructure.
Experts own the accountability.

We did not build another HR platform. We rebuilt the infrastructure underneath — AI-validated payroll, dual-layer billing, and continuous compliance monitoring — with human experts holding final accountability at every layer.

Core Capabilities

Four systems. One precision standard.

Four interconnected systems working in concert — each validated by AI, each owned by our experts.

AI-Validated Payroll Engine

Multi-country payroll processed in seconds. Gross-to-net calculations, tax deductions, social contributions, and currency conversions — validated by AI, owned by our payroll experts. Precision is not optional.

< 60sProcessing time per payroll run

Dual-Layer Billing System

Every invoice is automatically decomposed into two transparent layers: local statutory costs (taxes, social security, benefits) and ExtG service fees. Hidden fees are structurally impossible — not just a policy.

100%Cost transparency, by design

Continuous Compliance Engine

Labor law changes across every jurisdiction are monitored continuously. Contract terms, minimum wages, notice periods, and statutory benefits are validated and flagged for expert review — before they affect your team.

24/7Active regulatory monitoring

Contract Generation System

Locally compliant employment contracts generated in minutes. Each contract is tailored to the specific jurisdiction — mandatory clauses, probation terms, and termination provisions — reviewed by in-market legal experts.

Global Infrastructure

Owned entities.
Not vendor networks.

We maintain our own legal entities in every market we operate. This is the architecture that makes precision delivery possible.

25+ Owned Legal Entities

Direct legal presence across 25+ markets. No third-party vendors, no aggregated accounts. Your employees are hired through our own registered entities — full compliance, full control.

Unified Data Layer

A single source of truth for employee data, payroll records, and compliance documents across all jurisdictions. No fragmented systems, no data silos, no reconciliation overhead.

Enterprise-Grade Security

SOC 2 Type II compliant infrastructure. End-to-end encryption for all payroll and employment data. Role-based access control with full audit trails.

Automatic Regulatory Updates

When a country updates its tax brackets, minimum wage, or leave policy — the system flags affected contracts and queues updates for expert review. Compliance stays current without manual intervention.
