Fractional CTO & Technical Advisory for High-Growth Startups
Get executive-tier systems architecture, engineering team governance, and investor due-diligence preparedness without premature full-time executive overhead. Built for founders moving from seed to scale.
Solve the High-Cost Startup Architecture Dilemma
Early-stage engineering decisions compound exponentially. The wrong tech choices cost 6–12 months of rewrite downtime and millions in wasted burn.
Avoid Premature Executive Salaries
Full-time CTOs demand $300k+ in cash plus 2–5% equity. Get the same architectural authority and veteran discernment on a lean, flexible monthly engagement.
Zero Architectural Debt from Day 1
No premature microservices, no fragile vendor locks, and no unmaintainable spaghetti code. We enforce strict database invariants and type-safe contracts.
Investor Due Diligence Readiness
Represent technical architecture with confidence before angel and VC investors. Present clean RFC documentation, zero-trust security postures, and scalable unit economics.

Fractional CTO Advisory FAQ
What is a Fractional CTO and how does it work?
A Fractional CTO provides executive-level technology leadership, architectural roadmapping, and engineering governance on an agile, part-time retainer (typically 1 to 2 days per week). You get the strategic authority of a seasoned tech founder without committing to a full-time $300k-$400k executive salary and equity package before product-market fit.
How is this different from hiring a software agency?
Agencies are incentivized to bill hours and sell developer headcount, often building generic or over-engineered solutions that lead to vendor lock-in. As your Fractional CTO, I operate on your side of the table as a founder and fiduciary: protecting your cap table, selecting optimal lean technologies, setting high code quality gates, and vetting internal hires.
Do you write code or strictly provide high-level advice?
Both. Unlike corporate advisory consultants who only produce slide decks, I write core architectural scaffolding, review critical pull requests, design database isolation schemas, and implement CI/CD test gates. When your team encounters a high-concurrency bottleneck or edge runtime issue, I dive directly into the code and solve it.
Can you represent our technical architecture during investor due diligence?
Yes. I have guided startups through angel, seed, and Series A/B technical due diligence with top-tier venture funds. I author formal Architecture RFCs, security posture briefs, and infrastructure cost projections that give institutional investors complete confidence.
What is the typical commitment duration?
Most engagements start with a 3-month strategic sprint. This allows us to establish your foundational architecture, hire and onboard your founding engineers, and institute sprint velocity. After that, founders typically transition to a lightweight ongoing advisory retainer or a project-based governance model.
