Cayetano Iváñez

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.

New: Holafly Ultra. Unlimited data, plus health, wellbeing and travel support.

Lifesound.

The sound map of your life.

It started as a note on my phone, crossing the French Alps in a van in the summer of 2025. A year later that place exists: a map where your moments stay as sound, private by default. I built it alone.

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 read, and the music you’re hearing right now.

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
Look01 · Hong KongLooking up in Kowloon

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.
