What did ZERA build for Gwen Addo?

The system behind The Vision Masterclass: registration and payment by card, mobile money or cash, attendee communication from sign-up to the day, QR check-in at the door, follow-up after the event, alumni win-back, a paid replay of the sessions, and reporting for Gwen.

How much did The Vision Masterclass collect?

More than GHS 100,000 across its three cohorts. Cohort III, The Character Advantage, held in Accra on 22 August 2026, collected more than GHS 60,000 net from 45 paying attendees. More than GHS 14,000 of it came from 9 alumni of earlier cohorts who came back.

Why does automation matter for an event like this?

70% of Cohort III payments came in outside working hours, before 8am, after 9pm or at the weekend, and not one of them was missed.

Which ZERA service was this?

The Retention Engine, the tier of ZERA’s system built around bringing customers back after their first purchase.

More than GHS 100,000 from one masterclass, with the follow-up running itself.

Across the three cohorts it has collected more than GHS 100,000, more than GHS 60,000 of it from Cohort III.

What Gwen Addo needed

Gwen Addo is a business strategist, leadership coach and author, and the CEO of five businesses. Her Vision Masterclass brings founders into one room for a day of strategy, and every cohort is a serious revenue event for her business.

Payments came in by card, mobile money and cash, and registrations, payments and past attendees each lived in a different place. Nothing connected a sign-up to a payment, a seat at the door, or the next thing that person might buy, and nothing brought past attendees, the people most likely to buy again, back into the room.

What ZERA built

01
One record for every payment
Card, mobile money or cash, every payment lands in the same record, and every paid seat gets its own ticket.
02
Attendees hear from Gwen at the right moments
From sign-up to the morning of the event, every attendee knows what is coming and where to be, without anyone on the team sending a message by hand.
03
QR check-in at the door
Every ticket carries a QR code, so the team knows who has arrived while the event is still running.
04
Follow-up after the event
Attendees and no-shows hear different things after the day, and the people ready for more are moved toward working with Gwen one to one.
05
Past attendees brought back
Alumni of earlier cohorts are invited back for the next one. They already know the room, which makes them the people most likely to buy again.
06
The masterclass replay
The recorded sessions became a paid replay that only buyers can watch, offered to the people most likely to want it, so a one-day event keeps earning after the day.
07
Reporting
Gwen sees what the system brought in, cohort by cohort, without asking anyone for a report.
