Senior technology leadership,
scoped to the problem.
I work directly with one or two clients at a time as an AI-native fractional and interim CTO for $10M–$50M companies — no firm, no bench, no account manager. One method, The Business-Down Method™, run by the person you actually hire. Below are the shapes that work usually takes; pricing is published on the Fractional CTO page.

Five ways I come in.
Different names for the same thing: 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. My flagship.
AI-Native Transformation
I rebuild how the product is built and how the org runs so AI is the default, not an add-on, and I implement it, including the hiring.
Interim CTO
Full-time leadership in the seat, temporarily, to cover a gap or carry a transition until the permanent hire lands.
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.
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 an AI-native fractional and interim CTO. The core services are fractional CTO (his flagship), AI-native transformation, interim CTO, turnaround CTO, and technical due diligence for private equity. All are hands-on and senior, he designs the solution and implements it, including the hiring.
How do I know which one I need?
If you need ongoing senior judgment without a full-time hire, that's fractional. If you need someone full-time but temporary to cover a gap, that's interim. If delivery is broken, that's a turnaround. If you're evaluating an acquisition, that's 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 — roadmap sprints, PE due diligence — are quoted to scope. Full detail is on the Fractional CTO page.
Not sure which one
you need?
Tell me what's not scaling. I'll tell you honestly whether, and how, I can help.
