Called Lycos' Mambo Invitations, the service will add invitation and event planning services to sites throughout Lycos' network, including its primary home page and free email service MailCity.
Mambo allows users to send mass invitations and plan for events using email and the Web. For example, someone looking to organize a party can use Mambo to send an invitation to a list of guests.
Mambo will eventually unveil its payment service on the new Lycos offering. The service allows users to pay for events, sell tickets or collect money from other invitees.
Online party and event planning services have gained considerable hype in recent months. Last November, rival planner Evite.com secured $30 million in a round of venture capital financing from firms including August Capital and Staenberg Venture Partners. Mambo itself has received backing by Hummer Winblad Venture Partners and other angel investors.
Another competitor, eParties, has also attracted financing from Internet incubator eCompanies. And online music destination MP3.com recently acquired SeeUthere.com for $150.2 million in hopes of adding Web-based event management to its services.
The deal also marks another portal adding online invitations to its list of services. Last month, Yahoo launched Yahoo Invites to take a step into the space.
