Fractional CTO & AI Lead
You need a CTO for your AI product.
You don't need one full-time.
Most early-stage products need maybe a third of a CTO. So that's what I sell. I join your Slack, your standups, and your codebase. I decide the architecture and build the LLM features myself. When you're ready to hire a full-time CTO, I help you find them and hand over.
The demo took a weekend. Production is a different sport.
You wired up a prompt and it looked like magic. Then real users found the edges. Now it makes things up in front of customers.
The token bill doubled and nobody can say why. Or which model half your features even run on.
An investor asked how your AI works. The honest answer is it usually does.
You don't need a $300k-a-year CTO. You need a fraction of one. Someone who writes code, not memos.
Two ways to work together
It's as simple as 1, 2.
1. AI & Technical Audit
Find out what you actually have.
$2,500 fixed. One week.
I go through your product like an acquirer's due-diligence team. Architecture, security, infrastructure, and the AI layer: prompts, model choices, token costs, and the places it will embarrass you.
Five days later you get a plain-English report you can hand to investors. What's fine, what's fragile, what's dangerous, and a fix plan with honest estimates. If your product is fine, the report says so.
2. Fractional CTO & AI Lead
Someone owns the tech now.
$6,500 a month. Pause or cancel anytime.
Everything a CTO does, minus the salary, the equity, and the six-month search. Not a day parked in your calendar. I'm in your Slack, your standups, and your codebase all week. One standing call, no meeting theater.
Own the roadmap: architecture, build-vs-buy, a strategy that fits your runway.
Ship, don't just advise: I build the LLM features myself. Prompts, pipelines, evals.
Build the team: interviews, job specs, honest reads on agencies and contractors. First hires set the ceiling.
Fix the process: code review, CI/CD, deploys that don't require a prayer.
Survive due diligence: real answers on scaling, security, and cost. A named CTO on the team slide.
Founder
Daniel Studziński
I spent 8 years as a senior software engineer at Dscout. Now I'm the co-founder and CTO at BetterReviews, where AI interviews shoppers to collect reviews, analyzes thousands of those conversations, and writes the ad angles to match. Every lesson about prompts, costs, and edge cases was learned on live customers, not in a sandbox.
I design, I code, I deploy. With today's AI tooling, one experienced person covers ground that used to take a team.
Two clients at a time.
One slot is open.
I'm still the CTO at BetterReviews, so two clients is the cap. No pitch on the call. If you don't need me, I'll tell you.
