Is this right for you?
The leaderless company
You are between CTOs. Product decisions are being made without adequate technical judgment. Vendors are being evaluated without someone who can read through the sales pitch.
The founder-CEO
You are the de facto technical decision maker because there is no one else. You can make business decisions. You are not sure you can evaluate whether the infrastructure decision your VP is recommending is the right one for the next three years.
The investor-stage company
You are approaching a fundraise and need a credible technical voice for the raise, the due diligence process, and the board conversation.
What a fractional CTO actually does
This is not a consulting engagement where someone reviews documents and sends recommendations. A fractional CTO owns outcomes. That means sitting in board meetings and translating technical risk into business terms. It means being in the vendor evaluation when the company is choosing its data infrastructure. It means having the difficult conversation about technical choices that are accumulating risk. The difference between a consultant and a fractional CTO is accountability. Antonio Chagoury has been building and overseeing software systems for over 20 years. He has worked inside healthcare IT, federal contracting, and enterprise software environments: the kinds of programs where the technical decisions carry real consequences. He brings that experience directly to every advisory engagement.

Frequently asked questions
What is fractional CTO advisory?
Fractional CTO advisory is part-time senior technical leadership for companies that need experienced CTO judgment without a full-time executive hire. It includes architecture oversight, vendor evaluation, engineering hiring, board participation, and technical narrative for fundraising — with accountability for outcomes, not just recommendations.
When does a company need a fractional CTO?
When you are between CTOs, when the founder-CEO is making infrastructure decisions without adequate technical depth, when you are approaching a fundraise or acquisition that requires credible technical due diligence, or when vendor and architecture choices are accumulating risk nobody is owning.
How is fractional CTO different from consulting?
A consultant reviews documents and sends recommendations. A fractional CTO owns outcomes — sits in board meetings, participates in vendor selection, sets the engineering hiring bar, and translates technical risk into business terms with ongoing accountability.
