Before a major rebuild or replatform
Know what's actually there before deciding what to replace.
Start before you commit
Know what you're building on before you build further.
A focused technical audit — architecture, security, data and delivery — so the next investment decision is based on evidence, not assumptions.
When this is the right first step
Good moments for an audit
After inheriting an undocumented system
No original team, no documentation, and decisions to make anyway.
Ahead of funding, acquisition or exit
An independent technical view before it becomes someone else's due diligence.
When delivery has slowed and nobody can say why
Technical debt is usually visible once someone actually looks for it.
What you get
Deliverables
Current-State Map
A clear view of the existing architecture, dependencies and undocumented connections.
Risk Findings
Specific, prioritised risks — not a generic checklist.
Posture Review
Where the system stands against practical security and delivery standards.
Quick Wins
Improvements you can make immediately, independent of any larger decision.
Strategic Roadmap
What to rebuild, what to refactor and what to leave alone — prioritised by business value.
How it runs
A two to four week engagement
- Week 1
- Stakeholder interviews, codebase walkthrough and infrastructure access.
- Weeks 2–3
- Technical deep-dive across architecture, security, data and operations.
- Week 4
- Findings presentation, written report and roadmap workshop.
What to expect
The details
Typical duration
Two to four weeks, scoped to system size and complexity.
What you get
A written report and a live roadmap workshop — not just a slide deck.
Who's involved
A senior engineer who has actually built and audited systems like yours.
If the audit surfaces more than a quick fix
Some audits end with a bigger leadership gap.
If what you need is ongoing senior direction rather than a one-time report, CTO as a Service picks up from here.
