Hi @aberet, thank you for your interest in speaking at Zoomtopia! You do not have to be a sponsor in order to submit a talk proposal, anyone who has an interesting topic for our audience to share is welcome to submit. With that said, submissions that sound like product sales or service pitches are not likely to be accepted into the event program through the call for speakers process.
If you are interested in our sponsorship packages available for Zoomtopia 2022, the contact info for our sponsorships team can be found on the Zoomtopia FAQ page under the question "Is there an opportunity to sponsor at Zoomtopia?" Hope that helps!
