I'm building a robot that writes handwritten cards. With a real pen.
You type the message → robot writes it → I post it to your customer.
Dashboard, Zapier, API, and MCP.
Closed beta now. Public launch in November. For now sending only in Poland 🇵🇱.
Week 1 of marketing Paperjoy, honest numbers:
X post: 30,400+ views, 0 leads
Meta ads (free-sample CTA): ~13 USD per lead, about half of them really good
Most leads: Facebook??? + a comment from my dad.
After a couple of days with @bot it seems that it convinced me to consolidate my AI usage; go back to Cursor and cancel my Claude and Codex subscriptions.
still in awe what opus is capable of rn
I'm revisiting ideas I had a couple of moths ago that laaaazy models from back then said were impossible to do and it's just doing these things under 30mins.
It'd take me *days* just to research that topic, WILD.
I posted a thing I had fun building yesterday and the amount of haters rushing to tell me that I didn't invent it still makes me laugh.
How one can try bring others down for building stuff? 😅
170+ likes, 0 leads, dopamine through the roof.
Ads feel depressing but they sure worked better so far 😂

Not always glamorous.
I'm cleaning up and dissasembling some old projects to free up some shelf space today.
Ended up with a bag full of hardware to sort but that's future me problem 😅
I've been training really hard for a 70.3 IM this year and ended up being sick, on antibiotics and in terrible pain a week before the race 😪

I joined this small, hard-working team in 2023. In 2024 we got acquired. I can't express how grateful I am to have been taken along for this ride.
Fast forward two years, and I'm leaving to work on my own product full-time.
Today is my last day @ Stripe 🫡 What a wild ride.
Did I mention how annoying it is to wait for a part to be delivered?
I'm slowly switching from software to mechanical engineering.. it's rewarding but so painful
Yep, AI changed things here too and you can vibe-wire electronics, vibe-3d model but you still have to go through countless iterations that
1. Take much longer
2. Are way more costly
