Everyone sends text messages they later regret — just ask Brett Favre.

But sometimes the everyday texts that contain clever witticisms, pithy observations and inside jokes are also worth sharing, says Lauren Leto.

Ms. Leto should know. She is half of the duo behind Texts From Last Night, a site that publishes anonymous text submissions from users capturing the hilarious and often unspeakable moments from the prior evening.

The site does not publish everything it receives. “A lot of the texts go unused because they’re not funny and don’t fit into our set of guidelines because the jokes are too personal,” said Ms. Leto, 23. “It might be hilarious, but it makes no sense out of context.”

On Wednesday, her latest venture, called Bnter (and pronounced “banter”), which she created with Patrick Moberg, an illustrator and developer, is opening to the public and offering a way to, she says, “add context to those texts.”

The service allows people to post their favorite text exchanges in a simple format for others to read. People can follow each others’ accounts to keep track of the conversations they post, and comment on them.

“It’s a way to share conversations and interact with your friends,” Ms. Leto said.

Although the company, based in New York is only three months old, Ms. Leto has already put some venture muscle behind it. Although she declined to say how much, she said investors from Founder Collective, SV Angel and High Line Venture Partners contributed to an angel round of financing for the start-up while it was still in stealth mode.

Their early interest may not be a surprise considering that Texts From Last Night grew into a multimillion-dollar empire, which includes a popular iPhone application, and deals for a book and a television show.

Right now Bnter exists only as a Web site, but Ms. Leto says a similar iPhone app will have its debut as soon as it is approved by Apple.

Posting a snippet of a text exchange is already quite common on social networking sites like Tumblr, Twitter and Facebook. But Ms. Leto says Bnter could offer a much needed escape from networks like Facebook and Twitter, which are increasingly used in a professional capacity.

“It can seem too professional for a lot of people; they aren’t thinking about what links to post to best exhibit that side of themselves,” she said. “There’s a lot of interesting details in those conversations that don’t come out on Twitter and Tumblr.”

She thinks the site will especially ring true for teenage texters, who have been slower to adopt microblogging platforms like Twitter.

“This is the medium,” she said. “It’s where it is O.K. to post these things.”
