Braiins
Braiins, founded in 2011 by Jan Capek and Pavel Moravec in Prague, develops Bitcoin mining software and fleet management around the legacy of Slush Pool, the first Bitcoin mining pool launched in 2010 by Marek Palatinus. Its products include Braiins Pool with Stratum V2, Braiins OS+ firmware for ASIC optimization, and Braiins Toolbox for monitoring and profit switching across large fleets. Headquartered in Prague with a globally distributed team, Braiins serves industrial miners optimizing uptime, efficiency and hashrate transparency since Bitcoin's early years. The firm pioneered open mining standards, Stratum protocol improvements and transparency dashboards after taking over Slush Pool operations in 2013. Operating as a miner-aligned company, it emphasizes firmware correctness and pool reliability over custodial services. Expect an engineering-driven culture that values Bitcoin openness, fleet performance and building practical tooling for professional mining operations at scale.
