From Amazon to MVP: CTO-Level Strategy and Scalable Execution for Startups

CTO-level strategy. Enterprise-tested execution. Startup speed.

At Zero2Scale.io, we help startups and growing companies accelerate with high-impact technical leadership and a development team you can trust. Whether you’re building your first MVP or scaling to your next funding round, we bring the clarity, speed, and structure to get you there.

We know what happens when product outpaces tech—or when the wrong hire sets you back months. We’ve seen it, fixed it, and built systems that prevent it from happening again.

Who We Are

Our founder, Charles Ross, has spent 20+ years building and scaling platforms across some of the most complex, high-stakes environments in the world—including Amazon and Microsoft.

• 🏥 Onboarding platforms for 800,000+ hires annually across 66 countries
• 🏦 Banking systems, ATM telemetry, and casino payment networks
• 🏛️ Government case management tools, winning national innovation awards
• 🧪 Healthcare integrations including Epic App Orchard, HL7, and FHIR APIs
• ☁️ Cloud-native SaaS that cut infrastructure spend by 90%
• 🔐 Security programs that helped startups pass first-time assessments

At Amazon, Charles led the global transformation of hiring systems supporting one of the largest workforce operations on Earth. He built execution metrics, roadmap governance frameworks, CoE bar raiser mechanisms, and operational readiness reviews that are still used by Amazon teams today—driving consistency, scale, and $13.5M in annual projected savings.

At Microsoft, he served as a virtual CTO leading $268M in digital transformation for the largest for-profit healthcare system in the U.S., unlocking Microsoft’s largest healthcare enterprise agreement and driving full adoption of Office365 and Windows 10 across the enterprise.

He’s also stabilized venture-backed SaaS platforms drowning in tech debt, scaled telehealth systems through 5,000% growth, and helped public-sector clients win national awards.

Frameworks We’ve Built

Our leadership experience includes designing operational frameworks still in use at Amazon today:

• 📊 Execution Metrics Reviews tracking capacity, estimation accuracy, and delivery velocity
• 🚦 Roadmap Governance Frameworks driving cross-team clarity and accountability
• 🧪 Launch Readiness Templates for UAT, E2E, accessibility, and risk-based go/no-go decisions
• 🔍 Correction of Error (CoE) Process + Bar Raiser Program to reduce repeat failure
• 🧭 Operational Readiness Reviews (ORR) covering support, security, and production readiness
• 📅 Business Rhythm Mechanisms including monthly MBRs, QBRs, and kingpin alignment cycles

These same frameworks are now adapted to help fast-moving startups scale with confidence and control.
