Many businesses don't need a full-time CTO. They need an engineering leader who's built systems at scale: someone who can fix the foundation, unblock the team, and satisfy investor due diligence without the $350K+ salary.

What kind of Fractional CTO do you need?

Tier 1: Technical Oversight

Price: $6K–$10K per month (AUD)

For businesses that have a development team but no senior technical leader reviewing architecture decisions, code quality, or security posture.

• Architecture review and recommendations
• Tech stack assessment
• Code quality and security audit
• Engineering team performance review
• Monthly technical advisory

Best for: Non-technical founders with a small dev team (in-house or outsourced) who need a trusted senior technologist keeping the build honest.

Tier 2: Run Engineering

Price: $10K–$15K per month (AUD)

For businesses that need someone to lead the engineering function — architecture, team, delivery, and the connection between what gets built and what the business needs.

• Architecture design and oversight
• Engineering team leadership and mentoring
• CI/CD and delivery pipeline optimisation
• Sprint planning and velocity management
• Tech debt assessment and paydown plan
• Hiring and technical assessment support

Best for: Companies with 3–15 engineers that are shipping too slowly, drowning in tech debt, or struggling to hire and retain good developers.

Tier 3: Technical Transformation

Price: $15K–$25K per month (AUD)

For businesses that need a ground-up rebuild of their technical foundation — rearchitecting for scale, preparing for due diligence, or recovering from a critical failure.

• Scalable architecture design (10x–100x growth)
• Platform migration or rearchitecture
• Engineering org design and hiring
• Investor-grade technical due diligence prep
• Security, compliance, and infrastructure strategy
• CTO-level board and investor reporting

Best for: Companies preparing for a major funding round, experiencing "success disasters" (traffic spikes crashing the product), or recovering from an architecture that can't support the next stage of growth.

How much does a fractional CTO cost in Australia?

Most fractional CTO engagements range from $6,000 to $25,000 per month depending on scope. Technical oversight and advisory starts around $6K–$10K/month. Hands-on engineering leadership sits between $10K–$15K/month. Full technical transformation — rearchitecture, team build, due diligence prep — typically runs $15K–$25K/month.

When should a business hire a fractional CTO?

The most common triggers include: the site crashes under traffic, more time is spent fixing bugs than building features, the technical co-founder is overwhelmed by management, or investors are asking hard questions about the tech. If you're still validating a prototype with no-code tools, a fractional CTO is premature.

What does a fractional CTO actually do?

At the lighter end, they review architecture decisions, audit code quality, and advise on tech stack choices. At the heavier end, they lead the engineering team, design scalable systems, manage tech debt paydown, run hiring processes, and prepare the technology for investor scrutiny.

Fractional CTO or a full-time permanent CTO -- which do I need?

A full-time CTO costs AUD$350K+ per year in salary and significant equity. That makes sense for large engineering organisations. For most scaling businesses, a fractional CTO delivers senior technical leadership at 2–4 days per week. Enough to fix the architecture, unblock the team, and build for scale.
