Company Background
A mobile-first progressive web app that helps interest-based communities plan, coordinate, and verify in-person events. Piloted in the Pacific Northwest with 200+ users and highly positive reviews.
Most social apps stop at online interaction. HappyGo needed to bridge online planning and offline attendance — build community robustness through a trustworthy invitation system, support native chat without third-party dependencies, and verify that events actually happened in the real world.

Most social apps stop at online interaction. HappyGo needed to bridge online planning and offline attendance — build community robustness through a trustworthy invitation system, support native chat without third-party dependencies, and verify that events actually happened in the real world.
How we approach this project
We shipped a mobile-first PWA with a mandatory invitation and referral system at onboarding, in-app chat for event attendees, special-interest groups and professional clubs, and post-event verification via attendee survey forms. A "Looking For" capability lets users articulate specific goals so the platform can connect them with aligned people.
The challenge
The gap between "interested in this event online" and "actually showed up in person" is where most social platforms fail. HappyGo's bet was that stronger community primitives — trusted invitations, in-app communication without third-party dependencies, and real-world verification — could close that gap.
What we built
- Invitation & referral system. Mandatory at onboarding, so every new user enters with a social tie to the community.
- Native chat. Built in-house for event attendees — no third-party dependency that could leak data or break integrations.
- Clubs and interest groups. Spaces for special interests and professional clubs, linked to social media for event amplification.
- Event verification. Post-event survey forms confirm attendance and capture feedback.
- "Looking For" capability. Users articulate what they're hoping to find — a skill swap, a running partner, a mentor — and the platform matches them with aligned members.
The outcome
Shipped in six months (design, prototyping, testing, and validation). Successfully piloted with Pacific Northwest clubs, 200+ users, highly positive reviews.
