District-based Social Tables, the maker of event planning software, raised $8 million from investors that the company will use to hire executives, ramp up its sales effort and create new products, executives said Wednesday.

Bessemer Venture Partners and Thayer Ventures led the latest round of funding, with contributions from prior investors 500 Startups, Fortify Ventures, Middleland Capital and Militello Capital. Social Tables has raised $9.6 million to date.

“What’s really exciting is we’re a break-even company,” founder and chief executive Dan Berger said in an interview. “We had a [choice] of really scaling the business or continuing to grow it organically, and that’s why we decided to take this capital.”

Social Tables originally built a tool for event planners to create digital seating charts. That evolved into creating three-dimensional floor plans that event organizers and host venues use to plot where in a room to position items, such as the tables, buffet, bar or podium.

The software also allows organizers to check-in attendees once they’ve arrived.

The company has attracted roughly 2,500 customers in the last two years, Berger said, including hotels, convention centers and other event venues, as well as companies, associations, wedding planners and others who produce the events.

It’s clients range from Hyatt Hotels and Resorts to Georgetown University Law Center to Goldman Sachs.

“What’s really special about our product is it can serve different people along the event planning life cycle,” Berger said.

Social Tables counts 45 employees to date, with plans to add another 15 by year’s end.
