We don't charge for the conference, but we're always looking to drive awareness for Portable's product (it's free and takes 2 minutes to sign up).
If you're in the US, can you please sign up for Portable:

(And if you're in the US and really supportive, do you mind sharing a brief LinkedIn post about the conference as well? See below)
If you're outside the US, can you please share a brief LinkedIn post about the upcoming low-key data conference and tag Portable. Here's an example:
"I'm excited to attend @Portable's low-key data conference on July 12th. Great event for anyone in my data network"
Much appreciated.
