One operator.
AI leadership, scoped to the problem.
I work directly with you as a Chief AI Officer for mid-market US and Canadian companies, typically $10M–$50M, fractionally, on an interim basis, or full-time. No firm, no bench, no account manager. This is white-glove, bespoke work: I own the AI agenda, build the systems myself, and hire the team that carries them. One method, The Business-Down Method™, run by the person you actually hire. Below are the shapes that work takes; pricing is published on the Fractional CAIO page.
One executive,
accountable for AI.
Fractional, interim or full-time. Same mandate every time: the strategy, the governance, the portfolio, and the systems in production.
Fractional Chief AI Officer
The CAIO seat a day or two a week. I own AI strategy, governance and delivery, and I build the systems myself. My flagship.
Interim Chief AI Officer
The seat filled now, full-time and temporary, when the program has stalled or your CAIO has left.
Full-Time Chief AI Officer
The permanent seat, taken for a defined stretch, then handed to the CAIO I help you hire.
AI Governance & Risk
An auditable AI inventory, shadow AI brought into the light, and controls mapped to NIST AI RMF, ISO 42001 and the EU AI Act.
AI Strategy
An AI roadmap tied to the P&L, with the architecture and economics behind it, written by the person who stays to ship it.
AI-Native Transformation
Rebuilding how the product is built and how the org runs so AI is the default, implementation and hiring included.
A CTO in the seat,
however you need one.
The technology leadership underneath the AI work, and often the reason AI can ship at all. Fractional, interim, turnaround, due diligence, recruitment: senior judgment, hands-on, until the problem is solved.
Fractional CTO
Senior, AI-native technology leadership without a full-time hire. I set direction, build the team, and own delivery. The seat I've held at 30+ companies.
Temporary CTO
A CTO in the seat full-time for a defined stretch, to cover a gap or carry a transition, then hand off cleanly. Also called an interim CTO.
Short-Term CTO
Full CTO ownership for a stretch measured in months: cover the gap, hit the deadline, hand back clean.
Interim CTO
Full-time leadership in the seat, temporarily, to cover a gap or carry a transition until the permanent hire lands.
Portfolio Turnaround CTO
For PE & VC firms: a turnaround CTO who steps into a portfolio company, aggressively cuts costs, and rebuilds the work around AI.
Turnaround CTO
Stabilize troubled products and teams, then chart a credible path back to fast, predictable delivery.
Technical Due Diligence
For PE and investors: a clear read on code, architecture, team and risk before you sign, and an AI-native value-creation plan after.
Technical Recruitment
A CTO who builds your engineering team, not a resume pipeline: org design, personal vetting, and hires built for the AI coding era.
Read up first,
then call me.
The plain-English guides. What the Chief AI Officer role actually owns, what it costs in the open market, and which shape of it your company needs.
What is a Chief AI Officer?
The role explained: the mandate, the reporting line, and the four signals that say you need one.
What a Chief AI Officer costs
Full-time salary bands, fractional retainer ranges, and my published numbers side by side.
AI Innovations by Industry
The AI applications and agent systems I've designed across industries, some shipped, some blueprints.
The method is the discipline. The solution is never boilerplate — in the AI-native world the ground moves too fast for canned answers. I solve the problem in front of you with whatever is genuinely best right now.
By industry.
EdTech
I've run product and engineering for an online learning platform, I know where EdTech breaks and how AI changes it.
HealthTech
Former CTO of a healthcare EMR platform. SOC 2 Type I & II and HIPAA-grade compliance without slowing the roadmap.
E-commerce
Platform scale on the busiest day of the year, and margin-finding AI agents across fulfillment.
Before we talk.
What services does Oshri Cohen offer?
Oshri works as a Chief AI Officer, fractionally or on an interim or full-time basis, and as a fractional and interim CTO. The core services are fractional CAIO (his flagship), interim CAIO, full-time CAIO, AI governance and risk, AI strategy, AI-native transformation, fractional CTO, interim CTO, turnaround CTO, technical due diligence for private equity, and technical recruitment. All are hands-on and senior. He designs the solution and implements it, including the hiring.
How do I know which one I need?
Start with a fact that removes one decision: I hold the CTO and CAIO seats together, so you don't have to choose between AI leadership and technology leadership, and neither replaces the CTO, VP of Engineering or IT director you already have. From there: if AI needs an accountable owner but not five days a week, that's a fractional CAIO. If the AI program has stalled or the seat is empty, that's interim. If the exposure is the urgent part, start with AI governance. If the problem is technology leadership broadly rather than AI specifically, that's the fractional or interim CTO work. If delivery is broken, that's a turnaround; if you're evaluating an acquisition, technical due diligence. The fastest way to find out is a direct conversation.
How is pricing structured?
It's published and tiered. A fixed-fee Diagnostic from $20,000 is the front door; ongoing leadership is Advisory ($10K/mo, ~1 day a week), Fractional ($18K/mo, ~2 days), or Embedded/Interim ($30K/mo, 3+ days). Fixed-scope projects such as AI governance foundations, roadmap sprints and PE due diligence are quoted to scope. Full detail is on the Fractional CAIO page.
Are the CTO services still available?
Yes, all of them, unchanged. Fractional CTO, interim CTO, temporary and short-term CTO, turnaround CTO, portfolio turnaround CTO for PE and VC firms, technical due diligence and technical recruitment are all still offered. The AI seat is where most current engagements start, and at many companies the two jobs turn out to be the same job.
Which markets do these services cover?
The United States first, Canada second. Every service on this page is sold and delivered in both, remotely from Eastern Time, which is close enough to every North American office to be reachable when something breaks. Published prices are USD and identical in both countries. Whichever service you land on, you are hiring the same person under the same agreement.
Not sure which one
you need?
Tell me what's not scaling. I'll tell you honestly whether, and how, I can help.
