Hi everyone!! - quick question for those who are selling events sponsorship packages this year (or are planning on sponsoring events) How are you currently tracking ROI for $5k+ sponsors? sales, leads, logo visibility, others? Also I'm collating all the information I’m collecting and putting it into a report, if you want access to this happy to share it with you just send a DM.
