PORTLAND, Maine — Nine Maine companies made Inc. magazine’s national list of the 5,000 companies with the highest three-year revenue growth, a group dominated in Maine by Portland-based firms.
Six of the nine companies are based in Portland, and a seventh is located in Greater Portland.
While the state’s largest city hosts the bulk of the companies named to the 2015 list, Argo Marketing Group of Lewiston was the highest-ranking company from Maine, with three-year revenue growth of 669 percent, up to $13.8 million in 2014.
The company also posted the highest number of added employees for the three-year period of any company listed from Maine, with 373. An Indian technical support company picked Argo as a partner for its first U.S. expansion in July, a plan that would involve hiring another 300 employees.
The company also made it into the top 1,000 last year, when Auburn-based Electricity Maine cracked the top 10 for the Inc. list, which is based on revenue reports from the companies.
For the 2015 list, Argo was joined in the top 1,000 by the Scarborough-based MuniciPAY, which provides payment processing systems for governments, education and utility clients, and Vets First Choice, a mail-order pharmacy veterinarians can use to deliver prescriptions.
Another pharmaceutical company, Portland-based pharmacy Apothecary By Design, posted the highest revenue of any of the Maine companies listed, with $89.8 million in revenue in 2014, up 382 percent from about $23.5 million three years before. It ranked fourth of the Maine companies in the 2015 list.
The other companies that made the list were Eliot-based IT firm Abierto Networks and Portland-based companies Vision Payment Solutions, a payment processing firm; BlueTarp Financial, a credit manager for the building supply industry; Winxnet, an IT service provider; and Tilson, a technology company that designs and builds telecommunications networks and energy projects.
