Going offline:

New social networks emphasize fleshand-blood connections.

Not too long ago, “friending” someone involved more than just clicking a button on Facebook.

So in a retro twist to social networking, a wave of Web startups are encouraging users to get off their couches, away from their smartphones and tablets, and back into the real world.

“We have an internal tagline: Use the Internet to get off the Internet,” said Kathryn Fink, community manager at Meetup, an online-to-offline startup with 11 million members.

Hybrid social networks are connecting strangers with similar interests online, then directing them to meet in person for dinners, bar-hopping, bowling or biking excursions. Unlike dating or networking sites, these startups are focused simply on helping users make new friends and hang out face to face. If a hookup or job interview results, well, that’s just an added bonus.

On the sites, users create a free profile of

themselves with basic information and a photo, and search for get-togethers that interest them.

Before meeting face to face, people can post questions, offer parking or traffic tips and suggest topics to talk about. Events that cost money are usually paid for in advance online.

Friend finders

The sites are doing especially well among people in their 20s and 30s in big cities, where finding new people to hang out with can be challenging.

“When you’re in college, friends are basically thrown at you,” said Greg Self, 22, an assistant at a film production company. “You get off the bus, you step on campus, and everyone is in the same situation as you, and it’s super easy.”

But that wasn’t the case after Self moved to Los Angeles from Virginia earlier this year. He searched online for ways to meet new people and came across Grubwithus, a startup that enables users to create and attend group meals.

Grubwithus meals are hosted at restaurants and typically bring together six to 10 people who have never met. Everyone pays in advance for their meal on the Grubwithus site — the startup generally takes a 20 percent to 30 percent cut of each transaction — so there’s no mulling over the menu or bickering over the tab.

There have been Grubwithus meals geared toward traveling enthusiasts, vegans, Clippers fans and music aficionados.

One recent dinner in Los Angeles was devoted to people who love beer and the television show “Arrested Development.”

Growing quickly

Grubwithus has tripled its user base since the beginning of the year, with meal reservations growing 15 percent month over month; the company has more than 80,000 subscribers. It launched out of startup accelerator program Y Combinator and has raised $7.6 million in financing from investors including Ashton Kutcher and venture capital firm Andreessen Horowitz.

Since February, Self has attended nine Grubwithus meals and said he has made a handful of friends from the dinners.

“It’s definitely added to my experience in this city,” he said, though he added that some “can be hit or miss.”

Grubwithus Chief Executive Eddy Lu said users like such onlineoffline sites because they provide a safe way for people to meet — members identify themselves through their profiles and get the chance to communicate with one another online before meeting at a business or other public place. That way, he said, intentions are clear from the start.

“If you talk to a girl at a bar, she thinks you’re hitting on her; if you talk to a guy at a bar, he thinks you’re hitting on him. It doesn’t work,” said Lu, who co-founded Grubwithus after graduating from UC Berkeley and having trouble finding new buddies when he moved to Chicago.

Online matching

Another rising tech startup is Grouper, which connects two groups of friends for face-to-face hangouts after pairing them online.

Users apply for membership and are matched with someone else on the site. Each person then invites two other friends to join in for drinks; after prepaying online for the first round of drinks, the group of six meets at a bar chosen by Grouper. The setup takes away some of the awkwardness of meeting someone new alone, said Michael Waxman, Grouper’s co-founder and chief executive.

Launched in New York last year, Grouper expanded to Los Angeles in September.

“In a lot of ways, we’re the anti-Facebook,” Waxman said. “One of the original things that played into the genesis of Grouper was the idea that social software didn’t make a lot of sense. There’s this underlying paradox: Facebook, Twitter, social products — you usually use them by yourself by the glow of your computer screen.”
