B2B Marketplace, Events

Gatherly

Migrated a legacy data and web platform with zero downtime and 100% data integrity, and built the full stack of a two-sided B2B venue marketplace with an AI semantic-search layer that matches venues by meaning rather than keywords.

Key Results

0 / 100%

Zero downtime and 100% data integrity migrating a legacy platform

Semantic

AI search that matches venues by meaning, not keywords

Two-sided

B2B marketplace for discovering and booking event venues

Async

Celery-powered processing that stays responsive as the catalogue grows

The Challenge

Finding the right event venue is hard when search only matches keywords. Organisers think in terms of the event they have in mind — the mood, the format, the kind of space — but venue listings rarely use the exact same words. The result is a frustrating, miss-prone search experience on both sides of the marketplace.

A two-sided marketplace also has to stay fast and responsive as the venue catalogue grows, without the search and booking experience slowing down.

On top of that, the platform had to be migrated off an ageing legacy data and web platform — without losing data or taking the service offline.

The Solution

As full-stack developer, we migrated the platform off a legacy system with zero downtime and 100% data integrity, then built the entire marketplace — front end, back end and the asynchronous processing that keeps it responsive — with AI semantic search woven into the core booking experience rather than bolted on. Built on Django, React, PostgreSQL and Celery.

Zero-Downtime Legacy Migration

Migrated a legacy data and web platform with 0 downtime and 100% data integrity.

Full-Stack Two-Sided Marketplace

Built the front end, back end and asynchronous processing for discovering and booking event venues.

AI Semantic Search

Matches venues by meaning, so an organiser can describe their event and be matched to the right spaces even when the wording differs.

Responsive at Scale

Celery-powered async processing keeps the experience fast as the catalogue grows.

The Impact

Tangible Outcomes

Migrated a legacy data and web platform with 0 downtime and 100% data integrity

Built the full stack of a two-sided B2B venue marketplace

Delivered AI semantic search that matches venues by meaning rather than keywords

Wove AI search into the core booking experience rather than bolting it on

Kept the platform responsive as the catalogue grows with asynchronous processing

Key Takeaway

Migrated a legacy platform without losing data or uptime, then built an entire two-sided marketplace end to end — with meaning-based AI search at the heart of the booking experience rather than as an afterthought.
