A fractional CTO for agencies accidentally becoming software companies
Delivery standards, hiring, productisation paths for 20-80 person creative and marketing agencies. $4,500/mo Advisory, $8,500/mo full.
Who this is for
Agency owner at a 20 to 80-person creative or marketing agency building custom tech for clients, where delivery quality and hiring are unstable.
The pain today
- Agency accidentally becoming a software company
- Delivery quality inconsistent across client projects
- Hiring technical people feels high-risk
- Client work shows productisation potential nobody has time to pursue
- Full-time technical leader hire is expensive and not obvious
The outcome you get
- Fractional agency CTO at $4,500 to $8,500/mo
- Delivery standards documented and enforced
- Hiring plan for technical capacity
- Productisation paths evaluated and sequenced
- Technical risk reduced on client projects
When agencies need a CTO and when they don't
Agencies need a fractional CTO when 30 percent or more of revenue comes from custom tech delivery (apps, integrations, automation) rather than pure creative work. Below that threshold, a senior freelance architect or rotating lead is usually enough. Above the threshold, inconsistent delivery quality and hiring risk compound — CTO leadership protects margin and grows capability. For 20 to 80-person agencies, fractional CTO at $4,500 to $8,500/mo fits well; full-time technical leader usually not justified until agency is larger or productises.
Delivery standards and QA at agency scale
Agency delivery quality depends on standards. Code review practices, testing expectations, deployment procedures, documentation requirements. Without standards, quality depends on individual developer discretion — wild variance. With standards, quality levels across the agency. CTO role: establishing standards matched to agency's project types, training junior and mid-level developers, reviewing senior work. QA across client projects — not every project needs heavy QA; standards scope to risk. At W2O I led 15 engineers across 30+ clients and 25+ products — same pattern.
Productisation paths
Agency client work often shows productisation potential. Internal tools built for one client that generalise to others. Workflow patterns repeated across clients that could be a product. Automation patterns that multiple clients request. Productisation turns agency revenue from time-based (linear) to product-based (scalable). CTO role: evaluate productisation candidates for market fit and technical viability, scope product investment separately from agency revenue, lead productisation effort. Instill is my own example of productising a work pattern I saw repeatedly.
Pricing tiers
CTO Advisory $4,500/mo — 1 to 2 days per week. Delivery standards, hiring, strategic input. For agencies with existing tech lead needing senior guidance. Fractional CTO $8,500/mo — 3 days per week. Deep CTO role — standards, execution, team leadership, productisation. For agencies serious about building technical capability. 14-day money-back guarantee. Cancel anytime. US LLC invoicing. Typically 6 to 24 months depending on productisation ambition.
Case: Instill — productisation of an agency playbook
Instill: self-initiated AI skills platform with 30+ active users, 1,000+ skills saved, 45+ projects powered. Stack: Next.js 16, React 19, TypeScript, PostgreSQL, Vercel, MCP Protocol. Built solo to demonstrate the productisation path — taking a repeatable work pattern (structured AI skills library) and turning it into a standalone product. For agencies considering productisation, Instill is a working example of how to approach it without a massive team. Same patterns apply to agency productisation candidates.
When a senior freelance architect is enough
For agencies under 20 people with occasional technical complexity, a senior freelance architect on retainer (5 to 10 hours per month) may cover strategic technical decisions. Fractional CTO pays back when technical capability is a growing share of revenue or productisation is a real strategic bet. My target agency CTO clients are 20 to 80-person agencies where building technical leadership materially affects margin and capability. For smaller agencies, rotating freelance architect is more cost-effective.

Frequently asked questions
The questions prospects ask before they book.
- Can you help hire developers?
- Yes. Interview loops, technical assessments, levelling calibration, compensation guidance. For agencies hiring their first senior developer or tech lead, the hiring process is high-stakes — wrong hire sets back the agency. I manage the hiring process from role definition through offer. Typical first senior hire: 6 to 10 weeks from role post to start date. Subsequent hires smaller effort per role.
- How do you handle IP on client work?
- Agency-client IP arrangements vary. Typically: client owns deliverables (Work Made for Hire), agency retains generic patterns and tools. For productisation candidates, IP separation is important — the agency cannot productise what a client owns. CTO role: help structure client contracts so generic patterns remain agency IP, specific client-custom work transfers to client. Legal review by agency's counsel; I provide technical input on what should be separated.
- Can you lead productisation effort?
- Yes. Productisation is a major undertaking — separate team, separate sales motion, separate roadmap, separate legal structure often. I help evaluate productisation candidates, scope initial build, lead first version, and transition to dedicated product team once validated. Instill is my own productisation example. For agencies going this path, it is usually a 12 to 24-month CTO engagement minimum.
- What about delivery methodology?
- Agile for most agency work. Sprint cadence matched to client billing and release frequency. For agencies running many projects simultaneously, dedicated sprint per project or shared sprint with project-based backlog. Delivery tooling — PM tool (Asana, ClickUp, Linear), code review, deployment pipeline. Standards documented so new projects inherit patterns without reinventing. I establish methodology in first 60 days of engagement.
- Can you attend client pitches?
- For major technical pitches where credibility matters, yes. Especially for productisation sales or complex custom tech projects. I attend as the agency's technical leader, handle technical questions, and provide architectural depth clients want. For routine client pitches, your team handles — I focus on delivery quality once projects are won.
