Fractional chief AI officer for San Francisco companies whose teams already build with AI.

I'm Yiannis Papastergiou, an independent AI consultant based in Thessaloniki, Greece, working with companies of roughly €1M+ revenue. I give AI one named owner, a scoreboard and a quarterly rhythm, for one to three days a week. I have no San Francisco office, team or clients; the work is remote.

What is a fractional chief AI officer for a San Francisco company?

A fractional chief AI officer for a San Francisco company is a senior person who owns AI for one to three days a week instead of full time: a named owner for AI, a scoreboard of results, a quarterly plan and the rules for using AI safely. I work remotely from Greece as part of Own, monthly, and you can stop any time.

The short answer

If your engineers already ship AI, who owns AI for the rest of the company?

In a San Francisco software or services company, the people who build with AI are usually close at hand. What is often missing is someone who owns the company's own use of it: which tools the sales, support and finance teams may use, what customer data may enter them, who answers a customer's security questionnaire about AI, and who tells the board whether any of it is paying back.

Without an owner, those questions fall to whoever is loudest or most worried: the CTO between releases, the head of legal between contracts, a founder at night. Each gives a reasonable answer, and the answers do not add up to a policy.

Building AI and owning AI are different jobs. The second one usually has no name on it.

A fractional chief AI officer is that name, without the full-time salary.

The problem

What does a fractional chief AI officer San Francisco companies hire actually own?

Three named results are agreed each quarter, and the work is arranged around them. These examples show the kind of result, not client cases.

The scoreboard. Your named owner on the company side looks at the numbers that matter, such as hours back or response times, where everyone can see them.

Every week

A review with that owner: what shipped, what stalled, what a model or vendor change did to a workflow, and which customer AI questions arrived.

Every month

One leadership meeting on the next 90 days. I redo the plan with you so the next constraint is named before it becomes a crisis.

Every quarter

What AI may and may not be used for, how data is handled, and a short written answer you can give a customer or an investor when they ask.

The rules

If none of the three results is live, the next month is not invoiced.

What the owner does

Which California rules does an AI owner at a San Francisco company answer for?

I am not a lawyer, so treat these as questions for yours.

The California Privacy Protection Agency's regulations were approved in September 2025 and took effect on 1 January 2026. Businesses that use automated decisionmaking technology to make significant decisions must comply beginning 1 January 2027. Businesses subject to the risk-assessment rules had to begin complying on 1 January 2026, with an attestation and summary due to the agency by 1 April 2028. An AI owner keeps the list of systems that could fall under these rules, so that the legal question has facts behind it.

California's AB 2013, effective 1 January 2026, covers anyone who designs, codes, produces or substantially modifies a generative AI system for public use in California, for systems released or updated since 1 January 2022. Crowell & Moring noted in December 2025 that the law sets no threshold for substantial modification. If your team fine-tunes or wraps a model in a public product, someone should own that question.

What applies

Fractional chief AI officer, full-time hire or nobody: which fits?

Option

Fits when

Watch for

Plan, from €1,500, can come first if you would rather score readiness before naming an owner.

Fractional, with me

AI is used widely, no one owns it, and you want judgment 1–3 days a week

Remote from Greece; no San Francisco presence

Full-time hire

AI is your core product or you run several major AI projects at once

A long search and a fixed commitment before value shows

Nobody

One small team uses AI on low-risk work

Questions arrive from customers and investors with no one to answer

Three ways a San Francisco company can give AI an owner.

Options compared

When should a San Francisco company move from fractional to a full-time chief AI officer?

JRG Partners, in a September 2026 guide, says fractional engagements typically run one to three days a week, and lists when a company should convert to full time: AI becomes the core customer-facing product driving more than 10% of enterprise revenue, three or more major AI projects are live in production at once, the company moves from vendor APIs to training and hosting its own models on internal data, or it enters a heavily regulated market that needs daily compliance monitoring.

That list is from a recruiting firm, so read it as one view. It matches how I work: Own is built so you run a full round without me. If your company meets those triggers, the sensible outcome is that I help you hire the person who replaces me.

When to stop being fractional

How does a fractional chief AI officer work with a San Francisco company from Greece?

San Francisco is 10 hours behind Greece at the moment. Meetings sit in your morning, my early evening. I do not travel to San Francisco for this work, and the terms are monthly with no contract.

How it runs, remotely

Who would be your fractional chief AI officer?

You deal with the person who does the work.

As Product Owner at Natech I led its anti-money-laundering software from desktop to a modern web platform. It is now the company's market spearhead.

Regulated fintech

At Companies House, the UK's official business registry, I worked on the systems behind millions of searches and filings every year, and was security and quality champion.

Questions San Francisco leaders ask about a fractional chief AI officer

The only figure I print is Plan, from €1,500, with a seven-day refund. I do not publish a fixed retainer for the fractional chief AI officer role here. It is monthly, with no contract, and you can stop any time. Everything built stays yours.

How much does a fractional chief AI officer in San Francisco cost?

One to three days a week, depending on how much AI your company runs. Three named results are agreed each quarter. If none of them is live, the next month is not invoiced.

How many days a week is a fractional chief AI officer?

No. I am based in Thessaloniki, Greece, and all work for San Francisco companies is remote from Greece. I have no San Francisco office, no local team and no San Francisco clients yet. If you want someone in your office every week, a local firm is the better fit.

Do you have a San Francisco office or San Francisco clients?

The titles overlap. What matters is what you are given: a named owner on your side, a weekly scoreboard, a quarterly plan and written rules. An agency builds and leaves. My aim is that your company runs a full round without me.

How is this different from a fractional head of AI or an AI agency?

Because building a product feature and owning the company's own use of AI are different jobs. The owner decides which tools staff may use, what data may go in, who answers customer questions about AI and whether the results pay back.

Our engineers build AI features. Why do we need an owner too?

JRG Partners, in September 2026, lists triggers: AI as the core product above 10% of revenue, three or more major AI projects live at once, training and hosting your own models, or a regulated market needing daily compliance monitoring. If you meet them, I would help you hire.

When should we hire a full-time chief AI officer instead?

It adds questions. The CPPA's rules on automated decisionmaking apply from 1 January 2027, and AB 2013 covers anyone who builds or substantially modifies a public generative AI system. I am not a lawyer. The owner keeps the list of systems so your lawyer can answer.

Does California law change what an AI owner does?

Yes. Start with the free AI Growth GPS, which takes 3–5 minutes. If you want the inside view next, Plan is from €1,500. Each step ends with something you keep, and none is a condition of the next.
