Here are some of the latest startup and event updates from companies based in NYC.

Ignighter

Ignighter has relaunched their group dating website today. The company is calling the updates "version 2" which includes an update to functionality and site design. It also looks like they have redesigned their logo. Co-founder Adam Sachs noted regarding the update, "One new feature that Ignighter is excited to unveil is the world’s first group matching engine. The site has developed an algorithm that determines compatibility between groups of friends rather than just individuals. This will help Ignighter suggest groups for you and your friends to go out with."

Ignighter has also updated their groups function to allow users to follow updates for groups they subscribe to. Adam tells me that their groups function is similar to following someone on Twitter.

Their other update regards their blog and I think it's a smart move. They are adding more industry-related content to the blog in addition to site updates. This will help keep readers coming back and over time Ignighter might be able to convert them into trial users of the Ignighter dating service.

Buddy Media

Buddy Media has announced the launch of Builder today. Buddy Media describes Builder as, "a proprietary Social Media Development Platform—the industry’s only such platform to standardize and enable rapid deployment of branded social media applications across all social networks."

Buddy Media builds "app-vertisements" which are basically applications build on social networks including Facebook and MySpace. Builder allows customers to build app-vertisements that can be updated easily when the networks make changes to their platforms.

BootUp NYC

Another event has been added during Entrepreneur's Week this month. BootUp NYC will be held on April 22 at Webster Hall. Tickets are $5 and it seems to be a very long program running from 6:30pm to the wee hours of the night. Speakers include David S. Rose and Sanford Dickert. There will also be a variety of DJs and drink specials throughout the night.
