We made a MacBook scream when someone unplugs it.

Yowl sounds a full-volume siren and locks the screen. Free, open source, macOS 14+.

A deterrent, not theft-proof.

Sound on for our very low-budget demo 🔊

@TheJazib Helpstack and mojastran.

In spaceguardian we still do it normally

[Nejc Kocica @NKocica]

@amitkushh helpstack: an ai inbox that drafts replies for small shops. honest week: our own sales agent sent 294 offers and got 3 replies. fixing that in public.

[Nejc Kocica @NKocica]

@KhalilNoaman two small companies in slovenia, run mostly by ai agents. one builds websites for small businesses, and every site gets checked automatically on a phone and a laptop before a human ever sees it.

[Nejc Kocica @NKocica]

@gianmauric moja stran: ai agents that build a small business its website before it asks. 20 fully custom ones in one day, each from the business's own photos and story.

[Nejc Kocica @NKocica]

@AlexFinn we run ours from discord on a phone: every agent posts a card, one tap approves or changes it. the device matters less than teaching them to ask for a yes only when it's really needed.

[Nejc Kocica @NKocica]

@hnshah guessing managing agents. our hardest lesson so far: a prompt i write myself takes an hour, through the agent company it takes three days. so anything creative gets prototyped by hand first, then the agents roll it out.

[Nejc Kocica @NKocica]

@swyx and read the list they go to. building 20 custom sites for real businesses showed us 1 in 4 contacts in our own database were wrong or outdated. the best email in the world bounces off a dead address.

[Nejc Kocica @NKocica]

@gregisenberg #3 is real. we run two small companies on agents, and the bottleneck isn't the work: our slowest tasks had 4,075 hours of waiting for 11 hours of actual work. whoever fixes the waiting for one-person companies wins.

[Nejc Kocica @NKocica]

@Preda2005 @grok cleaning both at once is how we learned it too. one more thing that helped: the bot room only gets things that need a yes or no. anything that's just a status update goes to a log nobody has to read.

[Nejc Kocica @NKocica]

@MarlonCEO start with one boring job you do every week and give it to one agent with a clear stop rule. ours started with replying to customer chats. the fancy multi-agent stuff came much later.

[Nejc Kocica @NKocica]

@dayonefoundry the deleting part is why our experiment ran in a sandbox with no access to our real code. it rebuilt our whole product from scratch in 59 minutes for $36 instead. safer to let it start over than let it near prod.

[Nejc Kocica @NKocica]

@VadimStrizheus data point: our agents did 312 runs on opus 5.5 last week, $560 api-equivalent. one experiment alone (clone our own product from one sentence) burned $36 in 59 minutes.

[Nejc Kocica @NKocica]

@kloss_xyz step 8: give it one sentence and walk away. ours cloned our own saas in 59 minutes for $36. step 9 is finding a customer, and sadly there's no app for that.

[Nejc Kocica @NKocica]

@aiyeenpearlc building two small companies in slovenia with ~15 ai agents. one has built 4,600 websites for businesses that never asked for one. 4 paid. happy to connect with anyone who's cracked that last step.

[Nejc Kocica @NKocica]

@wanderjegson it gets worse: an agent vibe coded a clone of my own company's product in 59 minutes for $36. the cool project is free now. the customers never were.

[Nejc Kocica @NKocica]

@hnshah @a16z managing them is the real job. ~15 agents across two small companies, 312 runs last week. the rule that helped most: every agent message ends with what happens next and when, or it doesn't count as done.

[Nejc Kocica @NKocica]

@Surendar__05 tested exactly this on our own product. one sentence, no access to our code: 59 minutes, $36, 11,000+ lines. it got the inbox and the ai drafts. it did not get a single customer.

[Nejc Kocica @NKocica]

@mayuri_3015 claude code. last night i gave it one sentence, "clone our own saas", with no access to our code. it said done after 59 minutes and $36. the code part is solved. the project part (customers, approvals, support) is still on you either way.

[Nejc Kocica @NKocica]

but the code was never the hard part. selling is. and then everything that comes after building: keeping the platform running, talking to customers, support, the meta approvals. that's the actual company, and the clone has none of it.

[Nejc Kocica @NKocica]

everyone says you can vibe-code any saas in a weekend.

so i let an ai agent clone my own company's product. one sentence, no access to our code.

it said done after 59 minutes and $36. it's crazy how easy that was.

[Nejc Kocica @NKocica]

what it didn't get: messenger, whatsapp, instagram and email don't actually work in it. the code is there, but none of it is connected to a real account, and meta never approved it. and it copied our public website instead of building it.
