The new and free service is available to all organisers on Eventbrite.com and will roll out onto localised websites internationally later this month.
Kevin Hartz, chief executive and founder of Eventbrite, said: "At Eventbrite, we are focused on democratising the ticketing industry, and addressing the biggest problems organisers and attendees face: lack of innovation, customer support, and high ticketing fees.
"Reserved seating technology has been broken for years, and it shows in the experience organisers and attendees face today. The industry is hungry for an alternative, and this launch is our first step in eliminating the pain of outdated and expensive reserved seating tools and replacing them with simple, yet robust technology."
Eventbrite also revealed the company processed almost 60 million tickets in 187 countries during 2013, totalling more than $1bn (£598.1m) in gross ticket sales.
