Hartford-based Tecton Architects has been acquired by Agathos AEC, a national architecture and engineering firm backed by private investment firm Hunter Forest Capital.
The deal closed this month, the firms announced. Financial terms were not disclosed.
Tecton’s principals invested in Agathos as part of the deal, but the firms did not disclose the ownership structure.
Agathos was formed in early 2026 to build a nationwide architecture and engineering business through acquisitions, according to an announcement. Its other companies are engineering firms in California and Florida.
As part of the agreement, Tecton will retain its name and operate as an Agathos AEC company. Its executive principals — Ted Cutler, Jeffrey Wyszynski and Jeffery McElravy — will continue to lead the firm from its existing offices, and no workforce reductions are planned, according to Ian Adelson, spokesman for Hunter Forest Capital.
Adelson said Agathos expects to invest in additional staff, technology, administrative support and other resources to help Tecton grow.
Founded in 1979, Tecton employs more than 50 people and has offices in Hartford and Westerly, Rhode Island. The firm provides architecture, interior design and master planning services for education, public safety, healthcare, advanced manufacturing and corporate workplace projects.
Its current work includes a four-school building program in Barrington, Rhode Island; a new public safety headquarters in Peabody, Massachusetts; and facilities for submarine manufacturer General Dynamics Electric Boat.
Agathos said the acquisition adds its first architecture-focused business and gives it a presence in the Northeast.
Agathos’ other companies are Plump Engineering in Anaheim, California; JMPE Electrical Engineering in Santa Barbara, California; and Peterson Engineering in Pensacola, Florida.
According to Hunter Forest Capital, the Tecton deal was backed by Aldine Capital Partners, Petra Capital Partners, Pine Street Capital and Patriot Capital, along with First Merchants Bank. The firms did not disclose the financing structure.
The company said it is seeking additional acquisitions as it builds a nationwide architecture and engineering firm.
