We have been certified climate neutral since 2021.Strong Morals: Since our founding, we've turned down somewhere between $1mm - $2mm of work that didn't meet our moral standards. (Most of that was DTC brands that can't show a valid sustainability initiative).Async & Decentralized: We use tools optimized for calm, thoughtful communication, and opt for async whenever possible. We fight hard to maintain our focus time.Remote Friendly: Our company is fluent in remote work, making our workplace more decentralized, and democratized in the process.Ideas & Products: In our spare studio time, we work to build our own open source or internal products to diversify & bolster our income.
