I thought building the product would be the hard part. I was wrong.
When I started building PartyCall, I assumed the biggest challenge would be the technology.
Natural voice calls.
WhatsApp integration.
Real-time RSVP tracking.
Building the dashboard.
Making everything reliable.
We eventually got there.
But after launching, I discovered something much harder:
Getting the first users.
Like many founders, I started doing what seemed obvious:
Posting on Instagram
Creating UGC videos
LinkedIn outreach
Cold emails
Facebook groups
Reddit discussions
The product is live.
People who see it generally understand the value.
But turning that into actual signups has been much harder than I expected.
One thing that surprised me while talking to HR teams and event organizers is that almost everyone agrees on the problem:
Planning an event isn't the hardest part.
It's chasing people for RSVPs.
Multiple WhatsApp reminders.
Phone calls.
People replying at the last minute.
Not knowing the final headcount until the event starts.
That's exactly why I built PartyCall.
The challenge now isn't building the solution—it's finding the people who need it at the exact moment they're planning an event.
I'm trying to learn as much as possible from other founders who have gone through this stage.
If you've taken a B2B SaaS product from zero to its first 50 customers, what marketing channel or strategy made the biggest difference for you?
I'd genuinely appreciate any advice or lessons you've learned.
The channel list is broad, but the moment of need is narrow: an event has a date, a guest list, and a deadline. I'd partner with event planners or HR ops vendors and trigger outreach when an event is created, then sell the reduction in manual reminders and late headcount changes. For the first 50 customers, I'd measure reminders avoided per event before optimizing signup volume.
The interesting challenge isn't building RSVP automation—it's distribution timing. I'd keep validating whether the buyer is the event organizer feeling the pain daily or the attendee experience itself. The strongest positioning may come from owning the moment when RSVP chaos becomes urgent.
