Attendee list management outside the ticketing portal

The moment it breaks is when an event organizer needs to do something simple — remove a test attendee, update someone's email address, bulk-import a list from a CSV, or re-send a confirmation to one person — and discovers that their ticketing platform either doesn't allow it at all or buries it behind a process so painful it takes twenty minutes and still fails.

The specific complaints here are concrete: 'you cannot change an email someone has signed up with, and you cannot delete a user from your event,' 'I wish I could delete attendees without having to enter their email address,' 'I have issues with importing attendees using a CSV file,' and 'the email once loaded can't be sent to the participants again.' These aren't obscure edge cases. They're the weekly tasks of anyone managing a real event with real attendee changes.

Why does this gap exist? Because ticketing platforms are optimized for the attendee-facing flow — purchase, confirmation, check-in. The attendee record is mostly a transaction record, not a mutable contact. Changing it creates reconciliation problems for refunds and audit trails, so the platforms lock it down. The buyer — whoever selected the ticketing platform — usually isn't the same person doing attendee management day to day. So the friction lands on coordinators who didn't choose the tool and have no leverage to demand the vendor fix it.

This is a business because attendee management is a recurring operational task at every event, not a one-time setup step. The organizer who can't re-send a confirmation email to one attendee either gives up or does it manually outside the system, which breaks the audit trail. The one who can't fix a misspelled email address before check-in creates a check-in failure on event day. These are real, concrete costs that repeat every event cycle, and they don't get fixed by the ticketing vendor because fixing them requires loosening the very data controls that protect the vendor's own liability.

What to build

Build a web app that connects to major ticketing platform APIs and gives event coordinators a full attendee roster with editable fields, CSV import with conflict resolution, per-attendee email re-send, and soft-delete — syncing changes back to the platform where the API permits and flagging the ones it doesn't.

Where to start

Start with organizers running invite-only or hybrid events where the attendee list is partially pre-loaded from an internal CRM and partially from public registration — the CSV import and deduplication problem is acute there, and you can win on that one workflow before expanding to full attendee management.

The hard part

Syncing edits back to the ticketing platform is only possible where the API allows writes to attendee records — for platforms that don't, you're maintaining a shadow record that diverges from the source of truth, which creates its own confusion and undermines trust in the tool.

How it makes money

Per-event pricing for smaller organizers (around $25-50 per event) with a monthly subscription tier for teams running events continuously — low enough to expense without approval, high enough to cover support costs for the edge cases that will dominate early customer conversations.
