No. You can pledge as a guest without creating a Seed&Spark account. However, you can create an account during the pledge process and it takes only 30 seconds to complete. Creating an account means you can manage your pledge, and makes supporting future projects even easier.
If you pledged to the campaign as a guest, you won't be able to receive project updates from the creator during and after the campaign.
