About me

Hi, my name is Krystof Hilar
I am an entrepreneur developer and hacker.
I love building things and breaking them apart
I love to combine solutions to hard technical problems with a business view and critical thinking

In 2022 I was honored to be selected as one of Forbes 30under30 in the Czech Republic - Thank you Forbes!

This blog is a collection of my thoughts and experiences about my journey in areas of tech, entrepreneurship, performance and endless pursuit of becoming the best version of myself

If you would like to have a chat, please contact me through my LinkedIn profile

So what do I do?

In 2015, I co-founded cybersecurity startup ThreatMark with my friend Michal – a company securing banks against fraudsters by describing the identity of legitimate users through ML models (how they type, how they hold phones in their hand...)
We are improving the security of end-users (invisible authentication, detection of advanced scams) and improving the user experience at the same time (no need to re-write any boring OTPs - we know it's YOU)
I am currently spending most of my time as CTO of ThreatMark, where we protect more than 40M users against fraud

If you would like to know more about the technology we are building at ThreatMark, listen to the podcast below (it's in the Czech language)

Prior ThreatMark, I was an ethical hacker (penetration testing, reverse engineering), working for large enterprises (banking, telco, energy).
I've started multiple projects (non-profit, profit) before that in different areas (e.g. algotrading, gaming) and gained commercial experience developing software (web, mobile, backend).
