Market Diagnosis

Why Software Projects Fail.

Why do 70% of business software projects fail? Because the agency incentive model is broken.

The "Bait & Switch"

Agencies pitch with their Senior VP, then assign your codebase to junior freelancers or opaque offshore teams to widen margins.

Managed Product Teams

Product, design, engineering, and QA specialists who already know how to work together. Zero freelancers. 98% Retention.

Hard-to-Maintain Systems

Rebuilding every common feature takes time and can introduce security gaps and technical debt.

Reusable Software Components

We start with proven components for common needs such as sign-in, payments, and audit logs. This gives you a SOC2-ready foundation and can reduce development time by 40%.

The "Hourly" Trap

Vendors are incentivized to work slowly because they bill by the hour. Every delay creates profit for them and risk for you.

Simple Monthly Pricing

Fixed monthly retainers align incentives. Our only way to increase margin is to ship faster and cleaner.

High-Concurrency Payment Gateway

Legacy architecture locked during peak volume, triggering a 22% transaction failure rate and immediate revenue leakage.

Injected GoLang squad to implement an Event-Driven Platform (Kafka), Splitting the core gateway for infinite concurrency.

"Coretus didn't just patch the bug, they redesigned the core. We hit our best quarter ever without a single second of downtime."

Telehealth Expansion & Security

Urgent market demand for HIPAA-ready video. Internal teams lacked WebRTC expertise and security audit readiness.

Deployed a full-stack squad to build an E2EE Video PWA with automated audit logs, clearing SOC2 in the first month.

"Security was non-negotiable. Coretus brought automated compliance checks to the table from day one. We launched 3 months early."
