Braiins

Braiins develops Braiins OS custom ASIC firmware, Braiins Manager fleet-monitoring software, the Toolbox desktop app, and Braiins Proxy, alongside operating Braiins Pool, a bitcoin mining pool it describes as running since 2010. It also sells hashrate through a spot market, fixed-term contracts and Braiins Solo, plus a Forge line of home mining hardware and a sourcing service for ASICs and site equipment.

Customers are bitcoin miners, self-hosted mining operators and hosting providers, who use the software and pool, and buyers of SHA-256 hashrate. Revenue appears to come from software plans (a free Basic tier and a Pro tier priced at $250 per MW per month), pool fees, hashrate sales and hardware and equipment sales; the website does not give a complete breakdown.

The company states it is headquartered in Prague, Czech Republic, with remote work also offered, and that it operates a 6 MW hydro-cooled showroom in Houston, Texas. Its website lists open roles including product management, infrastructure, fullstack and AI engineering, product discovery, IT operations and technical support. The careers page cites Rust, Python, React, FPGA and Stratum V2 among its technologies.
