Institutional Diagnosis

The Platform Reality Gap.

Why do 70% of enterprise software projects fail to scale?
Because "Body Shopping" agencies prioritize billable hours over system architecture.

The Industry Norm

The Coretus Standard

The "Bait & Switch"

Agencies pitch with Senior Architects but assign your mission-critical backend to junior freelancers to maximize margins.

Sovereign Squads

Integrated units (Product + Eng + QA) that haveWorked together for 2+ years. Zero freelancers. 98% Retention.

Spaghetti Monoliths

Building from scratch invites Technical Debt and security drift. You pay for the agency's R&D, not their delivery.

Platform Accelerators

We inject 10,000+ hours of proprietary kernels (Auth, Multi-tenancy, Payments) on Day 1. Cuts dev time by 40%.

The "Hourly" Trap

Vendors bill by the hour, creating a perverse incentive to work slowly. Every delay increases their profit and your risk.

Outcome Retainers

Fixed monthly retainers align our goals with yours. We increase margin by shipping cleaner and faster.

Codebase & IP Sovereignty

You retain 100% legal ownership of the entire proprietary codebase, architectural diagrams, and deployment scripts. We operate on a work-for-hire basis with zero vendor lock-in.

Shadow Bench & Continuity

We maintain a 15% shadow bench for all platform squads. Vetted backend specialists are ready to rotate in within 72 hours, ensuring zero loss in sprint momentum or architectural context.

Global Roadmap Alignment

Platform Squads maintain a mandatory 4-hour real-time overlap with your HQ. This ensures seamless PR reviews, architectural syncs, and 24/7 reliability across US/EU time zones.

Tenant Isolation & Privacy

We implement physical and logical Database Sharding within your secure VPC. Our frameworks ensure strict multi-tenant isolation, clearing the highest bars for SOC2 and HIPAA audits.

Fixed Capacity Billing

Flat monthly retainers per squad unit. You pay for guaranteed engineering throughput, not variable hours. This allows for predictable CapEx forecasting and eliminates "Hourly Drift."
