We currently accept organizations only for the membership.
However, we are delighted to have your contributions to Autoware such as creating/amending programs by signing up our platform etc.
If you are interested in contributing, a good place to start is to look at the repositories on GitLab and see if there is anything on the issue tracker you can tackle.
You might also want to take a look at the list of active working groups where you can join to contribute.
Additionally, we encourage you to visit Discourse for discussions/collaborations with other Autoware contributors.
