I’m 33, software dev from Prague 🇨🇿

AI slowly took over my job

turns out that freed me up to run 10 projects at once

building in public now, $5k MRR so far

would love to connect with fellow builders, founders & indie hackers :)

@kimriiiii @MeetMattL Try code PFH30

Anthropic reported a Claude user to the police.

Lee County, Florida. On September 26, a user told Claude she would shoot up the local sheriff's office. The next day she added that she had bought a new gun.

The era of cheap AI coding is now officially over. And it will get worse.

If you are in tech, lets connect!

Added Debatly to a few AI directories.

Got 200+ trial signups.

Then I looked closer: bots from Russia/Belarus testing stolen cards and burning free credits.

Killed the free trial. Paid only now.

How do you stop card testers without killing real signups?

Take a look and let me know what you think: https://t.co/XybsPfe5Gf

Brutal feedback welcome.

[Martin Krupauer @Krupyer]

I completely rebuilt Debatly.

It started as an AI chat app with everything in it.

The problem? It tried to be everything.

Now it does one thing: Debate with AI. AI models debating each other, and you debating them.

Narrow beats broad. Let's see if I'm right.

@Joi2James Sure? Ok, I built @feetpikcom, a marketplace for buying and selling feet content

[Martin Krupauer @Krupyer]

Have you registered on PropFirmsHub yet? https://t.co/hqdd7RoiYp

[Martin Krupauer @Krupyer]

Never built a personal brand. Starting now.

I'll share everything from my projects here: wins, fails, real numbers.

Kickoff gift: I got 99% off codes for FTMO Futures through PropFirmsHub. Dropping them to my followers soon, so follow and hold tight.

https://t.co/2nxWqmRGM1 now has 500+ copies indexed.
189 of them registered a domain within 48h of launch.
The median clone has taken $20.44. Total. Ever.

I still bought a spot on one of them last week. FOMO is a hell of a drug.

[Martin Krupauer @Krupyer]

I run 8 projects. I've never posted about a single one.

One is @feetpikcom, a marketplace for selling feet pics. 20,000+ sellers, 9 languages, real revenue.

Everyone builds in public with a tidy SaaS. I'll do it with the messy stuff.

Revenue and failures. Follow if curious.
