The brief
The product problem we had to solve
Offline by Happy Hour was not a simple event listing site. The team needed a consumer product that could move people from discovery to a paid real-world event, then give operators the tools to manage bookings across cities.
The product had to work for three groups at once: users choosing an experience, hosts running it on the ground, and an internal team handling approvals, payments, attendance, and city-by-city growth.

Delivery timeline
From problem to production
02 · Build
Ship the booking core
Discovery, payments, registrations, host tools, and administration were delivered as one connected system.
03 · Scale
Support multi-city growth
The platform expanded to 20+ cities while the team kept running events and onboarding users.
04 · Proof
Reach the national-TV pitch
The product had already served 50,000+ users before the founders appeared on Shark Tank India Season 5.
The outcome
Built to keep working after handover
A single product connected event discovery, bookings, payments, hosts, and internal operations.
The codebase and infrastructure stayed under the client's control, with no platform lock-in.
The team entered its national-TV pitch with a live product, real usage, and multi-city proof.
