Creation is an infinite loop of input/output.

Here you have my outputs. Also some of my inputs.

Part one: what comes out.

Two kinds of output: products that scale and writing that helps me think.

Output · Build 01

Holafly Plans.

The first global data plan: one subscription, 160+ countries. It turned Holafly into the first global operator.

I’d been Holafly’s growth consultant since 2022. In 2024 I joined to build this from zero with the founders: sketched in Asia, first sold in Egypt, built between Dublin, Panama, Lisbon and Colombia. I still run it.

160countries. 160 SIM cards.

Physics, economics and the occasional bad analogy. This is where the inputs get processed: short notes and long essays.

NewThink 03 · Part 1 of 3

The currency was your mental health

“We’ve spent years living in the economy of attention and validation, and only now do we see what the currency was: our mental health.”

Part 1 of 3: where social media stands today, from someone who grew two of them. Essay, 6 min.

Part two: what goes in.

Three inputs that shape everything above: what I look at, what I listen to, what I read.

Input · Look 03

When I’m not building, I’m looking.

Film, mostly on the street. Every trip becomes a roll. Keep scrolling and it develops frame by frame.

Hong Kong: Looking up in Kowloon

Input · Listen 04

This is what sounds in my room while doing this

Find your vibe, play it loud, then keep reading. Everything gets better with music.

    Input · Read 05

    Books that changed how I build. Borrow the list.

    Mujō 01

    One more thing: Mujo Club.

    Mujō is a Japanese idea about paying attention to what’s in front of you, and appreciating it. Mujo Club takes that somewhere practical: a club for people who make things to express themselves. Still under construction. Come and have a look.

    Words fade when nobody looks at them. Move over them to bring them back.

    Say hello.

    That’s me, more or less. If you’re working on something creative that needs to grow, I’d like to hear about it.
