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.

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.

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.

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.

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.
