Fractional CTO Services
Senior Tech Leadership, On Demand
Every growing company reaches a point where technology decisions have million-dollar consequences, but not every company can justify a $300K+ CTO salary. Our fractional CTO service gives you battle-tested tech leadership for a fraction of the cost, with the flexibility to scale up or down as your needs evolve.
SENIOR TECH LEADERSHIP FROM $5K/MONTH - 70-90% LESS THAN A FULL-TIME CTO
Trusted by startups and SMEs across APAC • Ho Chi Minh City • Singapore • Seoul • Hong Kong
Who Needs a Fractional CTO?
If any of these scenarios sound familiar, you are probably at the stage where strategic tech leadership is critical but a full-time hire does not yet make sense.
Startups Pre-Series A
You have a working product and early traction, but investors are asking hard technical questions you cannot answer confidently. You need someone who can create an investor-ready technology roadmap, validate your architecture will scale, and prepare for technical due diligence. A full-time CTO would consume 30-50% of your seed round in salary alone. A fractional CTO costs less than one month of that salary.
SMEs Scaling Technology
Your business is growing and technology decisions are becoming more consequential. You need guidance on cloud migration, security posture, vendor selection, and team structure, but your current technical lead is focused on day-to-day delivery, not strategic planning.
Digital Transformation
Traditional businesses entering the digital space need someone to define the technology strategy, evaluate build-vs-buy decisions, and prevent costly mistakes. A fractional CTO brings experience from dozens of transformation projects.
Post-Acquisition Integration
After acquiring a company, you need someone to assess the acquired technology stack, identify integration paths, consolidate infrastructure, and manage the technical integration without disrupting either business.
Crisis & Recovery Situations
Your CTO just left, you suffered a security breach, or a critical system is failing. You need senior technical leadership immediately, not in 3-6 months when a full-time search concludes. Our fractional CTOs can step in within 48 hours and stabilize the situation while you plan your permanent hire.
Not Sure If You Need a Fractional CTO?
Our consultant can assess your current technical maturity and recommend the right level of engagement.
Engage GhostWhat a Fractional CTO Delivers
Technology Strategy & Roadmapping
Define your 6-18 month technology roadmap aligned with business objectives. Prioritize technical initiatives based on ROI, risk, and resource availability. Translate business goals into actionable engineering milestones that your board, investors, and team can all understand.
Architecture & Technical Decisions
Make the decisions that will define your technology for years: monolith vs. microservices, cloud provider selection, database architecture, API design patterns. These early choices compound. Getting them right saves hundreds of thousands in future refactoring costs.
Team Building & Mentoring
Define your engineering org structure, write job descriptions, conduct technical interviews, and design onboarding processes. For existing teams, provide mentorship to senior engineers, introduce best practices (code reviews, CI/CD, testing culture), and help your tech lead grow into a future CTO.
Technical Due Diligence
Prepare your technology story for fundraising. Create data room documentation covering architecture, scalability, security posture, and technical debt assessment. Participate directly in due diligence calls with investor technical teams. Startups with strong tech documentation raise funds faster.
Security & Compliance Oversight
Establish security practices before they become emergencies: vulnerability management, access controls, encryption standards, incident response plans. Ensure compliance with GDPR, PDPA, SOC2, or ISO 27001 depending on your market and customer requirements.
Vendor Evaluation & Crisis Management
Evaluate technology vendors objectively without sales pressure. Negotiate contracts with cloud providers, SaaS platforms, and development agencies. When things break, provide calm, experienced crisis management to resolve incidents and prevent recurrence.

Common Questions About Fractional CTO Services
What does a fractional CTO do?
+A fractional CTO provides senior technology leadership on a part-time or project basis. Responsibilities typically include setting technology strategy and architecture direction, evaluating and selecting tech stacks, building and mentoring engineering teams, conducting code and security reviews, preparing technical documentation for investors, managing vendor relationships, overseeing security and compliance, and providing crisis management for technical incidents. They bring the same expertise as a full-time CTO but work a fraction of the hours, making them ideal for startups and SMEs that need strategic guidance without the $250-400K annual salary.
How much does a fractional CTO cost compared to a full-time CTO?
+A full-time CTO in the US or Singapore typically costs $250,000-$400,000 per year in salary alone, plus equity, benefits, and bonus. A fractional CTO from Seraphim starts at $5,000/month for advisory-level engagement and ranges up to $15,000/month for hands-on strategic leadership. That represents savings of 70-90% compared to a full-time hire, while still getting access to senior-level technical decision-making.
When should a startup hire a fractional CTO?
+Startups typically benefit from a fractional CTO in these situations: pre-Series A when you need technical credibility for investors but cannot afford a full-time CTO, when scaling from MVP to production and architecture decisions become critical, when your founding engineer needs strategic guidance they cannot provide alone, during technical due diligence for fundraising rounds, or when evaluating build-vs-buy decisions for core technology. The right time is before technical debt becomes unmanageable.
What is the typical engagement length?
+Engagements vary by need. Project-based engagements like technical due diligence or architecture reviews typically last 2-6 weeks. Monthly retainers for ongoing strategic guidance range from 3-12 months. Many startups work with a fractional CTO for 6-18 months until they are ready to hire a full-time CTO, at which point we help with the hiring process and transition.
Can a fractional CTO help with fundraising?
+Yes, this is one of the most valuable services a fractional CTO provides. We prepare board-ready technology roadmaps, create technical architecture documentation that investors expect to see, help you articulate your technical moat and defensibility, participate in technical due diligence meetings with investor teams, and prepare data room materials covering technology, security, and scalability. Startups with strong technical documentation raise funds faster and at better valuations.
Technology Decisions Made Today Define Your Business for Years
The cost of a wrong architecture choice, a poor vendor decision, or a missed security vulnerability is orders of magnitude greater than the investment in getting expert guidance.
