Always-on AI agents · Fractional CTO

AI agents that run your processes.
So you can grow without hiring ahead

Claims intake, credit control, order entry, contract renewals. I build always-on agents that do the work end to end, keep a person on every decision that matters, and report what they save. For mid-market companies of 50 to 500 people, from first process to production in weeks.

Serial founder, four exits. PhD. Oxford Executive Leadership.

The Problem

The gap between AI investment and AI results
is where careers stall

The money is being spent. The pilots are running. The board slide has a roadmap. And the P&L hasn't moved.

of CEOs say AI has delivered no significant benefits

You've invested in AI. The numbers haven't moved.

Only one in eight report improvements to both cost and revenue. The problem isn't the technology. It's how it's being deployed.

PwC Global CEO Survey, 2026

from working demo to production-grade system

The demo worked brilliantly. Production didn't.

The gap between an AI demo and a system that runs unsupervised at scale is enormous. Bridging it takes someone who has done it before, not someone who's read about it.

Observed across dozens of AI engagements

of UK firms using AI use it extensively

Everyone has tried AI. Few have it running the work.

35% of UK firms with ten or more staff now use AI, up from 12% at the end of 2023. Only one in ten of them uses it extensively, and lack of expertise is one of the most cited barriers. The gap is not the tools. It's the build.

Why CTO Zen

Not another consultant.
A builder who's sat in your seat

Most technology advisors have either the technical depth or the commercial experience. Rarely both. I've built production AI systems, led national-scale transformation, founded four companies, and exited all of them.

I implement, I don't just recommend.

I build the agents myself, alongside your team, in your systems, with your data. The deliverable is a process running in production with measured KPIs, not a recommendation to build one.

Founder, CTO, board advisor.

Four exits. VC-backed. Built to profitability. I've sat in every seat at the table, not just the technical slice.

Growth without the headcount.

The agents take the reading, matching and chasing. Your team keeps the judgement. You absorb more volume without hiring ahead of it, and every month you see exactly what the agents handled and what they cost.

No platform to sell you. No lock-in.

Operated across AWS, Azure, GCP, and open-source stacks. The recommendation is always what fits your situation and budget. Not what earns a referral fee.

Rafal Bergman, builder of AI agents and fractional CTO
Founder · CTO · London

I'm a London-based technology executive and founder. I've built teams from zero, raised venture capital, delivered AI systems at enterprise scale, and led companies through every stage from idea to acquisition. Today I build AI agents that run processes for mid-market and PE-backed companies, and I still take a small number of fractional CTO roles.
