Restaurant waitlisting app NoshList has launched a new premium version that includes table number assignment, unlimited texting between a restaurant and diners, analytics, and more.

NoshList helps restaurants ditch clipboards and buzzers, notifying diners instead via text messaging that their tables are ready. The host or hostess uses the NoshList iPad app to keep track of diners, send them messages, and estimate wait times.

The NoshList service launched in February and hit 1 million diners seated in 75 days. Now, after nine months, the service has seated about 4.5 million diners and is used by more than 1,600 restaurants in the United States. Big-name NoshList clients include Red Robin and Buffalo Wild Wings.

NoshList Premium features include:

• Unlimited Two-Way Texting
• Table Number Assignment
• Large Party Functionality
• NoshGuest Autofill
• In-App Statistics
• Designated Local Phone Number
• 30-Day Exportable Analytics
• Weekly Email Summaries

Regular NoshList will remain a free service, but NoshList Premium will cost $49 per month per restaurant.

“There’s absolutely no way in which pen and paper, yelling, or buzzers can be innovated to drive sales, relay guest preferences, or deliver a better guest experience,” Cody Rose, director of restaurant services for Firespotter Labs, told us via email. “And for decades restaurants have clung tight to these antiquated methods because there was no alternative.”

NoshList-parent Firespotter Labs, based in Pleasanton, Calif., has raised $18 million to date from Andreessen Horowitz and Google Ventures. The company is also the brains behind UberConference, Nosh, and Jotly.
