The Challenge

Why Series A is the hardest technical stage.

Architecture decisions compound

The technical choices you make at Series A will either accelerate or cripple your growth for years. A monolith that worked at seed stage won't survive 10x user growth. But a premature microservices migration will drain your runway. You need someone who's made these decisions before.

Investors expect technical maturity

Series A investors aren't just evaluating your product — they're evaluating your technology organization. They want to see documented architecture, automated deployments, security foundations, and a credible plan to scale. Technical due diligence failures kill deals.

Team scaling begins

You're going from 3-5 engineers to 10-25. That means engineering management, coding standards, interview processes, and onboarding. The habits you set now become your engineering culture. Get it wrong and you'll spend Series B fixing it.

What We Deliver

What a fractional CTO does at Series A.

Tech due diligence preparation

We prepare your technology stack, documentation, and processes for investor scrutiny. Architecture diagrams, security posture, scalability analysis, and honest assessment of technical debt — ready before the term sheet.

Architecture scaling

We evaluate your current architecture against your growth trajectory and design the migration path. Whether that's database sharding, service decomposition, or infrastructure automation — we plan it and lead execution.

Engineering hiring (first 10-25 engineers)

We design your interview process, define role levels, write job descriptions, screen candidates, and conduct technical interviews. We've built engineering teams from scratch at multiple startups and know what good looks like at this stage.

SOC 2 and compliance foundations

Enterprise customers and sophisticated investors expect security compliance. We establish the policies, access controls, logging, and monitoring that form the foundation of SOC 2 Type I — without slowing down product development.

Vendor evaluations

Cloud providers, monitoring tools, CI/CD platforms, third-party APIs — every vendor decision has cost and lock-in implications. We evaluate options based on your specific needs and negotiate contracts that protect your interests.

Engagement Model

The typical Series A engagement.

3 days/week

Embedded in your team — standups, architecture reviews, hiring interviews, and board prep. Deep enough to own outcomes, not just advise.

$12K-$20K/mo

A fraction of the $350K+ total cost of a full-time CTO (salary + equity + benefits + recruiter fees). Cancel anytime with 30 days' notice.

6-12 months

Long enough to build the foundation, hire key roles, and transition to a full-time CTO when the time is right. We help you hire our replacement.

Due Diligence

What investors look for in technical due diligence.

We've been on both sides of technical due diligence — as CTOs being evaluated and as advisors evaluating targets. Here is what Series A investors consistently look for:

Documented architecture with clear scaling plan

CI/CD pipeline with automated testing

Security posture: access controls, secrets management, vulnerability scanning

Scalability plan tied to business growth projections

Engineering hiring plan with role definitions and timeline

Technical debt inventory with prioritized remediation

Incident response process and uptime history

Data backup and disaster recovery procedures

We prepare all of this before your investors ask for it. When due diligence starts, you're ready — not scrambling.
