The Big Bang Events is a controlled-beta marketplace connecting people planning weddings and other events with vendors across Toronto and the Greater Toronto Area. Its public listings cover categories such as catering, décor, photography, and venues, with vendor profiles, service areas, and portfolio photos to help users compare options. The platform serves 19 GTA cities, including Toronto, Brampton, Mississauga, Vaughan, and Markham, and supports weddings, cultural celebrations, corporate events, birthdays, galas, and community festivals.

Couples and planners can browse the marketplace at no cost during the beta and use the GTA Event Budget Calculator for cost estimates. The site also offers limited-preview AI planning tools, including an AI Event Planner and Smart Budgeting; many other tools remain in development. Vendors can register and create their own listings, which are reviewed before publication. The founding vendor offer is free for six months, followed by a flat $29 monthly fee, with no commission, pay-per-lead charges, or lock-in. The Big Bang Events emphasizes local discovery and planning for diverse cultural traditions.
