An internet company that handles employee uniforms for hotels and restaurants, and a small business that uses technology from Cold Spring Harbor Laboratory have been approved for Start-Up NY tax-free zones on Long Island, Gov. Andrew M. Cuomo announced Friday.

eParel LLC plans to use space in a former Gold Coast mansion that houses the tax-free zone on the LIU Post campus in Brookville. The company plans to hire 24 people over five years. It has not made an investment commitment.

The company, which has an office on Manhattan’s Bleecker Street, is developing a web-based service that helps hospitality businesses manage the use of employee uniforms.

eParel was founded by Kevin Schiesz and Matthew Wilson, who have both worked for restaurants, hotels and events companies.

It will be the second Start-Up NY participant at LIU Post since the private university was approved two years ago for a tax-free zone. Participating companies don’t pay state and local taxes for up to 10 years and their employees don’t pay state income taxes for as long as 10 years.

Cuomo also announced Friday a third Start-Up NY tenant for Farmingdale State College: Certerra Inc., a spinoff from Cold Spring Harbor Laboratory.

The biotechnology company has developed a screening technique that can determine which neurons in the brain are affected by drugs. It will be used in clinical trials.

Certerra plans to create two jobs over five years and invest $500,000 in equipment, officials said.

The company is the latest example of a trend that local leaders have said is important to Long Island’s economic future: commercializing inventions from research institutions and universities.

Friday’s announcement brings to 24 the number of Start-Up NY participants on Long Island. Most are based at Stony Brook University.

The Island is home to eight of the program’s tax-free zones.

After two years, Start-Up NY has created 408 jobs across the state, 38 of them locally.
