About
I'm a SaaS founder who codes like you.
I've built SaaS for 4 years, on the same stack as you. I know your weak spots because I made them myself, before I learned to find them. Today I test SaaS, always with your written go-ahead.

200k$
budget, hacked anyway
“I paid a real dev team, so I'm safe.” That's the most dangerous belief there is. Out of 178 SaaS I tested, 96% had a serious flaw, even ones built for $200k. Budget doesn't protect you: a clean, fast app can still leave the front door wide open.
What I check
Your business, gone overnight.
I look at your SaaS the way an attacker would, and tell you exactly what breaks. My flagship, the Zero-Leak audit: if I find nothing serious, it's free.
Can one customer see another's data?
The multi-customer nightmare. I make sure each client stays in their own bubble.
Can someone cheat your payments?
Pay less, skip the paywall, replay a transaction. I test your payments for real.
Are your keys and access exposed?
Passwords, API keys, admin access left lying around. Often visible without forcing anything.
Not ready for a full audit yet?
Start free. The scan shows in 60 seconds what an attacker sees from outside, no commitment.
How it works
The method, in 3 steps.
Three steps, and your written go-ahead first, always.
01
We scope it
We agree on what to test, you give me your written go-ahead. Nothing is touched without it.
02
I test like a real attacker
I look for where your SaaS leaks, and I prove it, without breaking anything.
03
You get a clear report
The problem, the proof, and how to fix it, in plain words. Delivered as a PDF and as Markdown ready to paste into Cursor or Claude Code. Once you've fixed it, I re-check for free.
FAQ
Questions & answers.
I paid a real dev team, aren't I safe?
It's the most dangerous belief there is. Out of 178 SaaS I tested, 96% had a serious flaw, even ones built for $200k. Budget doesn't protect you.
What's this about stealing my customer base?
On most SaaS I test, I get the whole customer base (emails, personal data, payments) in about 30 minutes, without really ‘hacking’ anything. It's usually a simple config mistake, and it's the worst kind of problem for GDPR.
What's the guarantee?
If I find nothing serious, the audit is free. That only happens 4% of the time. The risk is on me, not you.
Is this legal?
Only with your written go-ahead. I test only what you own and allow, within an agreed scope. No go-ahead, no test.
How much does it cost?
No public pricing, it's tailored to your case. We talk it through on a call, and you leave with a fixed quote, no hourly surprises.
