staff pm at ledger. paris, from stockholm. wine and cheese between deploys.
i'm the person in the room who asks "but who uses this tomorrow?" and then stays up building the answer.

what i've become.
four agents, one system. it thinks, runs, ships, and remembers — while i sleep.
the second brainthinksevery message, note and decision flows into one vault. the memory, so i can think.
the machinerunsthe infrastructure the agent lives on. a server in germany with its own cron jobs and its own opinions.
the couriershipsthe delivery lane. takes what the system writes and gets it out the door.

the thesis: when software is a commodity, the hardware is what protects you — your agent, your crypto, your digital identity. i run the core experience across btc, eth and sol, coordinating transaction check, clear signing and security research across six engineering teams. 8M+ devices on the other side of every call.

the agent era / nights and weekends
relay → favour
built in 48h
▌
48h build at World Build 3, won as RELAY. agents post tasks, humans accept, smart contracts escrow the money. coinfund noticed, world dev team reached out. it ships today as FAVOUR.
on-chain execution hashes. the problem: agents sound confident regardless of quality. you can't tell from the output. receipts are the only honest layer.
i was 9 when i rekt my own computer writing scripts in the terminal. the dream never changed, it's all over 15 years of journals: cli based, the machine does the work. now it's five terminals at 3am. everything i do flows into one vault. agents read my messages, score 1,200 contacts, curate drafts against my own taste, and one of them wakes up on a server in germany to leave a brief for me at 8am. the system remembers so i can think. a beautiful happening, finally having the software i always dreamed of.

chapter 05 / paris · 2026
3am. five terminals. snus and wine.
i was always the pitch guy. 16 hackathons explaining why something matters while someone else built it. ai closed the gap. now the nights look like this: five terminals, one brief, ship by morning. now the nights and weekends look like this:
next build window resets in48:00:00
notes to self
every agent demo looks amazing. then you ask who uses it tomorrow and the room goes quiet.
agents sound confident regardless of quality.
two agents i built, competing at the same hackathon. one caught the other about to push a private key. only a demo key, and it never leaked, because the other one caught it.
three things i keep rebuilding: agents that stop re-explaining, stop lying, stop forgetting.
product was better. distribution won.
the best hack is knowing when to stop hacking.
minimalism is where i am from. maximalism is where i live.
the winnings / drawn roughly
what the nights paid.
the tall one is bogotá. the flat stretch after is on purpose — in 2026 i stopped counting purses and started shipping.
the arc
art and science, all together. built on becoming: leaping before ready, and it keeps working out.

open data
the hackathon builder
it started in open-data hackathons. built sweden's largest series, 88 to 8,000. intent-based travel with SAS. the instinct: ship the thing, learn in public.

anotherblock
rode it into crypto. employee #4, 0 to 40K users, coinbase's first launch partner, rihanna and michael jackson on-chain. then it died by distribution. the product was better. distribution won. still the lesson that runs everything.
2025-
ai
the one-person team
now channeling it into ai. a five-agent os that thinks, ships and remembers while i sleep. one person, full stack, by morning.
the question that started all of it
what if it works out?
click it. go on.
this was the lagom version.
lagom (swedish): exactly enough. but you came this far.
