Who this is for

Technology Leadership.

Zadro Solutions works with a focused number of mid-market companies (typically $3M–$50M ARR), who need a senior technical partner embedded in their business, not a vendor on the outside.

Fractional CTO

You've outgrown your founding stack. Technical decisions are slipping. You need someone who owns the plan and is accountable for outcomes, not just a dev who executes tickets.

Technical Debt

Every new feature fights the old ones. Nobody owns the architecture. Your team ships slowly and spends too much time firefighting. It's costing you more than a retainer would.

Cybersecurity

Your insurer asked for documented security controls. A prospect wants your security posture. You're one breach away from a headline and you know it.

Product Growth

You have a product that needs to scale, a SaaS to build, or an AI feature that needs to work in production. You need architecture that holds.

Infrastructure - Step One

Not sure where to start?

Before anything gets fixed, built, or managed, we need to know exactly what we're working with. The Infrastructure Audit is that starting point. A full written report of your stack, security posture, and backup coverage, delivered in 7–14 business days.

  • Infrastructure Assessment
  • Security Review
  • Performance Analysis
  • Backup Gap Analysis
  • Deployment Review
  • Written Report
