Three dozen Connecticut companies are featured in the 2020 edition of the Inc. 5,000 – the 5,000 fastest-growing private companies in America, compiled by Inc. magazine and issued this month.


Three of the 36 Connecticut businesses earned a slot in the top 500 – software company Diameter Health, based in Farmington, was ranked at number 334.  Financial services firm Eastern Asset Funding, headquartered in Greenwich, was number 396, and Green Street Power Partners, an energy company in Stamford, was number 448.  Also reaching the top 1,000 fastest-growing companies was Ecochlor, a North Haven manufacturing company.

The Connecticut based businesses represent a wide range of companies, including real estate, IT, education, energy, financial services, telecommunications, construction, software, and human resources.

“We are absolutely honored to be included among the country’s fastest rising stars,” said Eric Rosow, Founder and CEO of Diameter Health. “We attribute our success to the commitment and dedication of our employees as well as the strong relationships and partnerships we foster with our clients.”


Diameter Health, which transforms raw patient information into high quantity and quality interoperable data for healthcare organizations, ranked number 44 across the software industry among 326 honorees. In the health sector, Diameter Health ranked 24th and in the state of Connecticut, Diameter Health ranked first among the fastest-growing private companies.

Green Street Power Partners is a national developer, financier, owner, and operator of solar energy systems for businesses, schools, nonprofits and municipalities expanding across the country, developing solar energy solutions that are customized for its clients. Their select team of solar industry veterans, in-house legal counsel, experienced operations professionals, and structured finance experts create adaptable, high-yield turnkey solar solutions to optimize client revenue.

The mission of Ecochlor is to end the wide-spread environmental damage to our coastal ecosystems that is caused by invasive aquatic species carried in the ballast tanks of ships. The North Haven company’s collaborations with innovative maritime business solutions providers are intended to deliver enhanced economic performance by providing environmentally sound products and services to the maritime industry.


Placing among the top 2,000 were real estate firm OneWall Management, Stamford (#1,142); telecommunications company Point5 Managed Services, Old Saybrook (#1,146); IT System Development firm Vertex Analytics, Manchester (#1,342); business products & services company Waterfront Promotional Merchandising, Westport (#1,476); and marketing firm Scrum50, Norwalk (#1,530).  Also reaching the top 2,000 fastest growing companies in the nation were New England Yankee Construction, West Haven (#1,912), financial services firm Choice Merchant Solutions, Hartford, (#1,933); advertising business The Lockwood Group, Stamford (#1,952) and education company InGenius Prep, New Haven (#1,962).


“The companies on this year’s Inc. 5000 come from nearly every realm of business,” says Inc. editor-in-chief Scott Omelianuk. “From health and software to media and hospitality, the 2020 list proves that no matter the sector, incredible growth is based on the foundations of tenacity and opportunism.”  The annual Inc. 5000 event honoring the companies on the list will be held virtually from October 23 to 27, 2020.

Ranking at number 4,022 was Cheshire-based Assisted Living Services, the only Connecticut health care company to earn a place on the highly regarded list, which is gleaned from more than 30 million small businesses nationwide.

“One key to our success is that we put most of our emphasis on achieving audacious quality goals first and foremost.  The other is that we strive to surround ourselves with the very best talent – from managers to field staff,” explained Ron D’Aquila RN, CEO. Officials attribute the company’s 87% revenue growth over the last three years to its expansion into Fairfield County, moving its headquarters from Meriden to a larger office complex in Cheshire, as well as continued cultivation of positive relationships with key state agencies, business partners and industry associations.

“We have remained a family-owned and operated company since 1996, and to achieve this level of national recognition is a testament to the dedication of our entire team,” says Mario D’Aquila, MBA and Chief Operating Officer of ALS. “We pride ourselves on leading industry trends as we constantly adapt to a changing business environment. Demand for quality in-home care has exploded as Baby Boomers retire and prefer to age in place.”
