The internet noticed
For a long time, we struggled to capture what our light actually feels like in person. This is the closest we’ve come.

The Window goes into production
The first batch of 50 starts this week. Rory and I fly out to China to supervise the line.
Ready for a September launch.

Remotes are now assembled by our Window manufacturer with rigorous QC. Unit costs keep coming down.

We have registered a US LLC. Americans can now pay with Affirm, and our HSA/FSA application is in - so people can put pre-tax health money towards a light.
