Fractional CTO in New York City

A fractional CTO is a senior technology leader who takes ownership of a company's architecture, infrastructure, vendor decisions, security, and technical roadmap on a part-time basis, usually through a monthly retainer, instead of joining as a full-time executive. The role suits businesses that need real technical authority but do not have the volume of work, or the budget, to justify a full-time hire. Eyal Gantz holds this role for several clients, and because he still writes code every day, the strategy stays grounded in what is actually buildable rather than what looks good in a slide deck.

Eyal Gantz prices fractional CTO work as a monthly retainer scoped to what the business actually needs, quoted after a discovery call rather than published as a rate card, because the hours and the responsibility differ enormously between a five-person brand and a company running several integrated systems. The comparison he uses is a full-time CTO hire, which in the United States runs $250K a year and up once salary, equity, and benefits are counted; a fractional engagement is a fraction of that. Market rates across the industry vary widely by hours and seniority, so treat any single published range as a weak benchmark.

The usual trigger is one of three situations. Technology has become load-bearing for revenue, but nobody senior actually owns it, so decisions get made by whoever is available. Or there are developers, agencies, or vendors in play and no one qualified to judge their work, set direction, or say no. Or the business is about to make an expensive, hard-to-reverse decision such as a re-platform, a rebuild, or a new integration, and wants someone accountable for that call. If the technical work is small and well defined, a fixed-price project is the better fit.

It starts with an audit of what exists: the codebase, the infrastructure, the vendors, the security posture, and the things quietly waiting to break. Fragile pieces get fixed first. Then a roadmap gets set against actual business goals rather than technical wish lists, and from there the work runs month to month: shipping improvements, reviewing changes, handling incidents, evaluating vendors, and reporting in plain language to whoever runs the business. Because Eyal Gantz builds as well as advises, plenty of the roadmap gets implemented by him directly instead of handed off.

Yes. If a company already has developers, a fractional CTO leads them: setting architecture and standards, reviewing code, running the release process, mentoring, and shielding the team from thrash so they can actually finish things. If there is no team, the work gets built directly instead, and hiring only starts when the volume genuinely justifies it. Eyal Gantz has done both, including multi-year engagements where he began as the only engineer and stayed on as the technical owner while the business grew around the system.

An agency sells a team: an account manager who relays messages, a project manager who schedules them, and developers the client never meets. An advisor sells opinions and leaves the execution to someone else. A fractional CTO engagement is both halves in one person, accountable for the outcome. The person on the discovery call is the same person who sets the architecture, writes the code, configures the infrastructure, and answers the phone when production breaks. The trade-off is honest: only a limited number of engagements run at once, and a poor fit gets declined.
