Advisory

Technical leadership without the $200k hire.

You're making six-figure technical decisions with nobody in your corner. A Fractional CTO gives you a senior engineer for strategy calls, investor questions, architecture decisions, and hiring — without the full-time commitment.

What you get

  • A trusted technical voice in every investor meeting and commercial conversation
  • Architecture decisions made by someone who's shipped, not someone who's guessing
  • Hiring interviews led by an engineer who knows what 'senior' actually means
  • A written technical roadmap aligned to your business milestones
  • An honest assessment of your current codebase and the risks inside it
  • Conflict-of-interest-free advice — we'll tell you to buy off-the-shelf when that's right

Right for you if ...

What we cover

Investor & board support

Technical questions from VCs, due diligence support, architecture diagrams for the data room. We prepare you and join calls when it matters.

Architecture & technology decisions

Monolith or microservices. Build or buy. Which database. What to rewrite. We make the call with you and document the reasoning — so the next engineer understands it.

First engineering hire

Defining the role, writing the job spec, running the technical interview, and setting the bar before the first offer goes out. Your first hire sets the culture.

Technical roadmap ownership

A 6–12 month roadmap written in business outcomes, not tickets. What you can demo, what unlocks your next milestone, and what's a distraction.

Team and vendor review

Is your existing dev team or agency doing good work? We read the PRs, sit in the sprint reviews, and give you an honest answer without the politics.

Conflict-of-interest-free advice

We will sometimes tell you to use an off-the-shelf tool instead of building. We've done it for our own clients. Advice that protects your runway is how we keep clients for years.

How we work

01

Technical baseline

We review your existing codebase, infrastructure, and team setup. We don't advise in a vacuum — the business model shapes the risk profile.

02

Roadmap session

A structured 2-hour session to define your 6-month technical milestones and the decisions that need to be made to get there.

03

Embedded advisory

Weekly or async availability. We join your team standup, attend investor calls, review hiring decisions, and weigh in on architecture choices as they arise.

04

Monthly review

A written monthly summary: decisions made, risks identified, what's changed in the roadmap and why. You have a record, not just memories of a call.

Right-fit packages

Fixed prices. No hidden fees.
