First offices of 6 companies worth a combined $21 trillion.




In Austria, a CEO of a startup lives barely any better than a regular employed developer A former boss of mine (an exited founder) wanted to buy a new desk Instead of going to IKEA, she went to a site for used furniture and searched for one there, because it was much cheaper For my Eastern European mind, this is incomprehensible If you put years of your life into building a business and take on the risks, you should be rewarded accordingly You should definitely have enough money to go to a damn IKEA and buy the best possible desk there (and write it off in taxes later!) But this is not the case here The system is engineered for equality and social stability The monetary distance between employers and employees is minimal, thanks to predatory income taxes Great if you are an employee, soul-eating if you are a founder



Jane Street made ~$40B in 2025 with 3,500 employees, a ~2x from the year before. At ~65-70% profit margin, that's $8M profit / employee, the highest for a 1000+ ppl company. High-frequency trading continues to be the most efficient money making engine. I want to share an old story about my Jane Street interview in 2014. Jane Street was known for hiring a lot of math, physics and CS olympiad winners from top universities and putting them through many rounds - including, for trading roles, a gauntlet of mental math. It was my 6th interview and my final round and I recall being asked "What is the next day after today in DD/MM/YYYY where all the digits are unique?" They'd toy with you and say "You can use a pencil and paper, if you want" but you knew that was an instant no. Painstakingly and as quickly as I could, I came to an answer. "How confident are you that this is correct on a 0-1 probability scale?" the interviewer said. "0.95", I blurted out, not fully knowing how to answer that. "Are you sure?" After thinking harder for a few more seconds, I realized I could've flipped the digits around to get a closer date. I gave the interviewer my answer. It was correct. "0.95 huh?" he chuckled. That's when I knew I failed. Note: fwiw, other companies that come close in efficiency are - Tether ($90M+ profit/emp) - Hyperliquid ($80M+ profit/emp) and on revenue: - Valve ($50M/emp) - OnlyFans ($37M/emp) - Craigslist ($14M/emp) - Anthropic ($12M/emp, run rate) - OpenAI ($8M/emp, run rate) For comparison, Nvidia is very efficient at scale and is $4.4M/emp.




I owe you an apology @VoltEuropa. I wasn't really familiar with your game. 🙃
