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.

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.
56%
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.

01
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
1 in 10
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.
01
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.
02
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.
03
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.
04
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.
About Rafal
Built companies. Raised VC. Shipped AI at scale.
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.

Process Audit
2 weeks · Fixed scope
Pick one to three processes. I measure the baseline, show what an agent could run end to end, rank them by return, and write the build spec. Half the fee is credited against a build.
Deep review of your stack, architecture, AI approach, and team. Delivered as an investor-ready technical assessment. The clearest way to know where you stand.
Always-on agents that run one process end to end, on the systems you already have. Shadow mode first, then 10% of live volume, then scale on evidence. A person on every decision that matters.
Monitoring, exception review, accuracy and cost tuning, model upgrades and small changes, with a monthly report of work handled, hours returned and cost per item.
Quarterly technology reviews, investor call prep, and a senior external voice for board credibility. An independent technical perspective when the stakes are high.
