Snagajob is moving into former co-working space Launch Pad's office on Meeting Street later this month in a move that caused a chain reaction of moves among Charleston startups. Provided

Charleston's technology startups are playing musical chairs.

Several of the region's most prominent up-and-coming companies have moved their offices in recent weeks, a chain reaction that owes partly to their growth.

That was the case for Snagajob, the human-resources software company, which is moving this month to Meeting Street just south of the historic City Market. The company, which was split between two buildings on King Street and formerly was called PeopleMatter, says it wanted to consolidate its workforce under one roof, and it was running out of room.

But with Snagajob taking over two floors of 174 Meeting St., other tech tenants had to move out. They included the co-working space Launch Pad, which pulled out of the Charleston market in September, citing rising rents downtown.

They also included Atlatl Software, which builds a 3-D modeling product for manufacturing sales. The company moved last month to upper King Street, next to The Daily coffee shop.

Marc Murphy, its chief executive, says the new office is roughly the same size as its space on Meeting, but it will be customized to fit Atlatl. The company is taking a former warehouse that until recently had dirt floors in some areas. It was fixed up to give its roughly 45 workers a "showcase space," Murphy says, including an open floor plan.

Atlatl took over another tech company's space: The cybersecurity startup Soteria, which was tucked in the back of the warehouse, recently moved to Daniel Island, chief executive Chris O'Rourke says.

Health rating

Yelp now shows health ratings for some restaurants in South Carolina, putting inspection scores alongside diner reviews.

South Carolina is only the third state to connect its inspection scores to San Francisco-based Yelp's pages. Georgia and Florida also list their scores on the service, along with 21 cities and counties elsewhere.

The new feature will eventually cover every restaurant in the state, Yelp spokesman Jordan Bantista says. The company is pairing its listings with data scraped together by the Baltimore startup HDScores, which collects health inspection records, and expects to line them up within the next few months.

"We work to match their data to existing Yelp restaurant pages using both business names and addresses," Bantista said in an email. "Some of these match up perfectly, and the rest have to be matched by hand."

Boat coat

The S.C. Research Authority says it's giving $50,000 to Mount Pleasant-based Engineered Marine Coatings, matching part of a federal grant the company received.

That's on top of a $225,000 grant the company received from the National Science Foundation under the federal Small Business Innovation Research program.

Engineering Marine Coatings is trying to produce an environmentally friendly coating to keep algae and barnacles from growing on ships' hulls, work that began at Clemson University. The company's grant application says it needs the funding to demonstrate its product's effectiveness and prepare to scale up production.

SCRA, for its part, says it will match grants under the federal Small Business Innovation Research and Small Business Technology Transfer programs. Applications for a matching grant are due Feb. 7.
