CTO-as-a-Service / Fractional Technical Leadership
Get a 15-year technical architect on your team for a fraction of the cost. Strategy, architecture review, code audits, and team mentoring — the judgment of a full-time CTO, sized to what your stage actually needs.
Estimate Your Cost Savings
A rough, directional estimate — not a quote — comparing typical fractional CTO cost against a full-time hire at your team size.
Why Companies Need This Before They Need a Full-Time CTO
Companies with 5–50 engineers are large enough to need strategic technical leadership but not yet ready for a full-time CTO's salary and equity. A fractional CTO closes that gap — architecture guidance, code reviews, team mentoring, and vendor evaluation, without the full-time overhead. Think of it as your most trusted technical advisor, on retainer rather than on payroll.
Technology roadmap decisions increasingly need to account for how AI systems will interact with your product — API design for AI agent integration, content architecture for AI search visibility, and infrastructure decisions that anticipate AI-driven traffic patterns. This is now a standard part of our architecture review, not a separate specialization.
Core Capabilities
Get a 15-year technical architect on your team for a fraction of the cost. Strategy, code reviews, architecture decisions, and team leadership — without the full-time salary.
Define your technology roadmap and architecture strategy. We align technical decisions with business objectives, evaluate build vs. buy decisions, and create execution plans your team can deliver.
Review your current architecture for scalability, security, and performance gaps. We identify technical debt, recommend modernization paths, and design systems that scale with your growth.
Provide technical leadership to your engineering team. We run code reviews, establish engineering standards, mentor senior developers, and improve code quality and velocity.
Deep audit of your codebase for quality, security, and maintainability. We identify critical vulnerabilities, performance bottlenecks, and refactoring priorities with clear remediation plans.
Create a technology roadmap that supports your business growth over 12–36 months. We plan migrations, evaluate new technologies, and ensure your tech stack evolves with your needs.
We evaluate whether your infrastructure and content architecture are ready for AI agent integrations and AI-search visibility — a factor increasingly part of technical due diligence and fundraising conversations.
What We Deliver
The judgment and hands-on execution of a senior technical leader, part-time.
Design scalable, secure system architectures that support your business growth. We create architecture decision records, design documents, and implementation guides your team can execute.
Establish code review processes and engineering standards that improve quality and velocity. We review critical code paths, set up linting and CI checks, and train your team.
Evaluate technology vendors, SaaS tools, and outsourcing partners objectively — technical capabilities, security posture, integration complexity, and total cost of ownership.
Mentor your senior developers and engineering leads with 1:1 coaching, architecture discussions, and help developing the skills to make better technical decisions.
Audit your application security, infrastructure, and data handling practices. We identify vulnerabilities, recommend fixes, and help implement security best practices across your stack.
Select the right technologies for your specific needs — frameworks, databases, cloud services, and tools based on your requirements, not hype or personal preference.
Process

We assess your current technical landscape — architecture, team capabilities, code quality, and technology stack — identifying critical gaps and quick wins.
We develop a technology strategy aligned with business objectives, creating a prioritized roadmap and establishing the standards your team needs.
We guide implementation of key initiatives — architecture changes, technology migrations, process improvements — working alongside your team with hands-on guidance.
We provide ongoing technical leadership through regular office hours, architecture reviews, and strategy sessions — your trusted technical advisor for critical decisions.
