Hi Valentin, take us through a day at work, what does that look like as Fingerprint's co-founder? What inspired the platform?
I'm a fan of remote and asynchronous work. Most of my day is spent reading and summarizing information from emails, Slack, sales calls transcripts etc. I usually have 2-3 short meetings per day with team members and sometimes with customers. My favorite tool is Notion, where I prefer to keep all my information and create short documents that help me put my thoughts in order.
I started the open source library, FingerprintJS, as a hobby while I was working as a JavaScript developer a couple of startups ago. The project became very popular quickly with thousands of websites using it. Over time, I realized that there was a real demand for a solution like Fingerprint that no other company was offering. So when Dan left the previous company, he asked me if he could work with me on the commercial version of Fingerprint, and that brings us to where we are now.
