I almost killed my company on Friday.
$90,000. One Azure bill. Gone.
Let me tell you what happened because I think founders need to hear this.
We built an amazing document intelligence system at Whisperit. It analyzes our customers' files: PDFs, Word docs, scanned documents, using OCR. It works beautifully and user love it.
But we had a bug.
A small email with a zip file. Inside the zip, a PDF. Some weird edge case that created an infinite loop in our code. The virtual machine would crash, restart, and try to reprocess the same document. Again. And again. And again.
We pay more than one cent per page processed.
You can imagine what happened next.
I saw the graph and my stomach dropped. An exponential spike. The kind of curve you want to see on your revenue chart (!!) not your cloud bill. The forecast for next month said $400,000+.
I thought: this must be a mistake.
Emergency 🚨. Check everything. It wasn't a mistake.
The worst part? We had a warning. Back in November we had a $25K unusual spike. We fixed it. Added upload limits. I thought we were safe.
But I never set a spending cap on Azure. Never set up alerts for unusual usage. I knew I should. I just didn't do it.
I went through every stage:
Denial → "this can't be right"
Anger → screaming at myself
Shame → feeling small, really small
Tears → first time in a long time
I cried that evening. Not because of the money, because I imagined having to close Whisperit. My team. Everything we built. Gone because of one missing setting and my stupidity.
The week had been incredible. New version shipping. Lots of new users. Sales going well. Migration going well. Growing the team responsibly. And then Friday hit like a truck.
Remember my last post about mistakes? Yeah. We're still making them. Bigger ones.
$90,000 is the price of a NICE car. Paid for a bug and a missing checkbox.
Here's what I'm doing RIGHT NOW so this never happens again:
1. Hard spending limits on every cloud service — no exceptions
2. Alerts at 50%, 80%, 100% of expected spend
3. Circuit breakers in our processing pipeline — if a document fails 3 times, it stops
4. Weekly cloud cost review — not monthly, weekly
5. Every API endpoint gets a budget ceiling
If you're a founder reading this:
Go set your spending limits. Today. Right now. Before your next meeting. Before your next coffee. It takes 10 minutes and it could save your company.
We move fast. That's our superpower. But speed without guardrails is a bomb with a timer.
I know what doesn't kill you makes you stronger.
I really hope this one doesn't kill me.
Still standing. Barely. Building. 🚀
My favorite place to work? Swiss trains.
🚄 Great focus
🌆 Arrive in the city center, minutes from clients
🌄 A different landscape every time
It’s almost like Swiss trains are my office.
Off to Fribourg for another client demo today. Wish me luck! 🤞
Ten years ago, I prototyped hardware with them in Shenzhen 🇨🇳. It was an unbelievable and priceless experience. Feeling so grateful and happy staying in touch
Despite building and using AI every day, I still start most ideas on paper. 📝
Today, I had to do a pitch deck.
Before Gamma or any AI tools—just me, my notebook, and a few hand-drawn slides.
Any tech AI entrepreneurs still trust pen and paper for the first scribble?

Waaaaw I am really excited to share the latest work done during X-mas "holidays" 🎉 ✨
Tell me, can you analyse a legal case that fast? 😬
Whisper + AI + Agents + RAG = 🚀
3. What used to take me painfully long now takes minutes. Not only does it allow me to find qualified leads, but it also allows me to craft personalized messages for each of them. 🎯
2. Thanks to AI, I built a web scraping app that scans businesses on Google Maps, takes screenshots of their website, and then uses GPT-4 Vision to do my analysis. And it works! 😱
Before, I had to scroll through businesses on Google Maps and look at their websites one by one to consider whether or not to contact them.
Merry Christmas everyone!🎄Wishing you and your little ones a magical holiday filled with joy, magic, and imagination!Stay cozy and keep dreaming ⭐️✨ #FamilyTime #Xmas

Businesses that make money by collecting and selling detailed records of private lives were once plainly described as "surveillance companies." Their rebranding as "social media" is the most successful deception since the Department of War became the Department of Defense.
