How we work

We believe that there’s a better balance between the poles of freelancing & full-time, and for that reason, Sanctuary works differently to most shops:

• Transparency & Ownership: We release our Profit & Loss statements to the community each year, open source our best ideas, and talk business & money with everyone in the company. We’re proud to run our business with integrity, and for that reason, we share everything with our team & community.
• **150% Carbon Negative:** Our studio offsets 150% of the carbon we use to do business each year, dated back to our founding in 2015. We turn down work that is not in line with our morals, and we encourage our peers to do the same. We were certified climate neutral earlier this year.
• **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 ersify & bolster our income. We create amazing technology products for our clients, so why not for the studio?
