Built PartyCall: Automate Event Invitations, WhatsApp Reminders & RSVP Tracking

Hi everyone! 👋

After months of building and testing, I'm excited to share PartyCall, a platform designed to simplify event invitation management and RSVP tracking.

One thing I kept noticing was that whether it's a company event, team outing, startup meetup, birthday, wedding, or community gathering, organizers still spend hours manually:

Sending WhatsApp invitations
Following up with people who haven't responded
Calling guests individually
Managing spreadsheets
Trying to estimate the final headcount

We built PartyCall to automate that entire workflow.

What PartyCall does

✅ Send WhatsApp invitations with event details and location links

✅ Automated reminder voice calls in a natural voice

✅ Guests simply answer "Yes" or "No"

✅ Live RSVP dashboard

✅ Import guest lists from Excel/CSV

✅ Reuse guest lists for future events

✅ Multi-language support (English, Hindi & Telugu)

✅ Auto-follow-up for guests who haven't responded

The goal isn't to replace WhatsApp—it's to eliminate the manual work that comes after sending invitations.

We're currently looking for founders, HR teams, office managers, event organizers, and anyone who regularly hosts events to try PartyCall and share honest feedback.

🌐 Web App: https://partycall.ai/

📱 iOS App: https://apps.apple.com/us/app/partycallai/id6762263163

I'd genuinely appreciate your thoughts:

Is this a problem you've experienced?
What features would make a tool like this more useful?
Any feedback on the product or positioning is welcome.

Thanks for reading!

    The reusable guest-list feature seems especially valuable for people who organize events repeatedly, while weddings and birthdays are often one-off needs. Are HR teams and event professionals the main customers you want first, or do you expect individual hosts to be just as important?

  2. 1

    Automating RSVP tracking is such a specific, real pain point — anyone who's manually chased people for a headcount knows the pain. Does it integrate directly with WhatsApp's API, or is it more of a wrapper around existing group chat behavior?

    really neat usecase man! i def think landing page could show the narrative better

  4. 1

    The interesting part isn't automating invitations—it's removing all the manual coordination that starts after you hit send.

    That feels like a much clearer problem to own.
