01 · What I watch

I read the noise, so you don't have to.

Today in AI: what I'm watching, so you don't have to.

02 · What I believe

Every system starts as a belief.

Memories

My father's shop, age 15. Where I learned business: customers, margins and turning up every day.
Cardiff University. MSc in Computer Science, after a software engineering degree in Greece.
KLA. My first chapter: software in the semiconductor industry.
Companies House. Software for the UK government.
ARAG UK. Legal insurance tech. I started as the sole developer for 500 people.
Natech. AML Product Owner. I brought AI into the team’s processes and the product.
On my own. Since October 2026: helping founders and their teams put AI to work.
The first sale. September 2018. My first ever online sale. I cried from happiness.
What I changed after 100 sales. After 100 sales I stopped dropshipping. I couldn't give customers the service I wanted, so I held my own stock.
2,000 handwritten notes. I wrote a handwritten message to each of my first 2,000 customers. Slow, and nobody asked for it.
From $5 a day to $3,000. My ads went from $5 a day to $3,000 at peak. Some days my partner and I packed 200 orders.
12,000 customers, 22% came back. My jewellery store served 12,000+ customers. 22% came back. The best school I ever went to.
What stopped the store. In 2020 shipping got three to four times slower and dearer. The one part I didn't control stopped my store.
Dishes and toilets at 19. At 19 I washed dishes and cleaned toilets in bars. I've earned my own money since my teens.
Making code run faster on GPUs. Both my dissertations were on making algorithms run faster on Nvidia GPUs. Speed has always been my thing.
Too niche to stay. After five years in semiconductors I left. It made me valuable to one employer, not to the market.
Closer to the business. I never wanted to write code all my life. I wanted to be closer to the business.
February 2023. February 2023: one of the first paying ChatGPT users. That's when I saw what kind of change we're living through.
Twice, alongside a job. Twice I ran a business alongside a job. Alongside is a way to start, not a way to stay.

03 · Who I listen to

No prescription before I've listened.

It starts with you talking. No recommendation before I understand how your business really works.

04 · What I say

Plain English about AI, out loud.

05 · What I've done & what I can do

Processes, automated. AI, inside the product.

What I've done

Clients and projects

What I run for myself

The 4:30am news desk. At 4:30 every morning an agent reads the last day's AI news, picks ten and briefs me by 7:15.
An inbox that drafts, never sends. At 7:20 on weekdays my assistant labels my inbox, archives the noise and drafts replies. I send.
My week, planned beside what happened. Every Sunday an agent plans my next week in a separate calendar, beside what actually happened.
A voice agent for customer service. I built a voice agent that answers customer service calls for my business, to show what voice AI can do.
A second brain that backs itself up. Every night my skills, documents and builds back up to a private second brain. Agents must know you first.

07 · Why

I help people and businesses. Right now, AI is how.

For good and for profit. AI should do both: help people and pay its way.
People first. I help people and businesses. Right now, AI is how.
Listen before prescribing. No recommendation before I understand how your business really works.
Brute force first, optimise later. Brute force first, optimise later. Get one thing working, then improve it.
200 that perform like 1,000. A company of 200 should perform like a company of 1,000, and still employ all 200.
Ignored, not invested in. People leave when they feel ignored, not when they feel invested in.
Through an entrepreneur's eyes. The world would be better if everyone saw it through an entrepreneur's eyes, even if they never start a business.
I count the families. A 100-person company affects 300 or more lives once you count families. So I count the families.
Keep hiring juniors. Today's juniors are tomorrow's seniors. Stop hiring them and one day nobody knows how your business works.
Fix it before you speed it up. Faster gives you more of what you already have. Fix the service first, then add AI.
Read-only first. Start an agent on read-only. Let it earn the rest. My inbox assistant has never sent an email.
