## About Caladan

VC Fund · Singapore, Singapore

AlphaLab Capital Group is a technology-driven trading group that transacts over $2B daily in cryptoassets on 40+ exchanges, both centralized and decentralized. Since 2017, we have consistently generated exceptional returns (aka alpha). We were one of the first movers in quantitative trading on the blockchain, and today we operate thousands ofalgorithms 24/7 on a globally distributed network of trading servers. We see blockchain as the foundational technology of our generation. Just as ship-building innovations in the 1450s launched the Age of Exploration or TCP/IP in the 1970s launched the internet as we know it, blockchain now opens up new worlds of possibility. Much of the infrastructure, applications, and software that we will all take for granted in a few decades are only glimmers in someone’s imagination today. We founded AlphaLab because there is huge potential in building that future. It’s also going to be a lot of fun.
