Seque Manufacturing Services

What Seque Manufacturing Services does

Seque Manufacturing Services is a US-headquartered contract electronics manufacturer specializing in complex cable and wire harness assembly, electromechanical integration, and PCB assembly for medical, industrial automation, capital equipment, robotics, and aerospace and defense OEMs. Founded in 1991 and based in North Billerica, MA, the company operates from approximately 150,000+ square feet of self-owned facilities spanning Boston (55,000 sq ft with a dedicated NPI Center of Excellence), Xiamen, China (75,000 sq ft with a 2,000 sq ft Class 10,000 clean room), and Tijuana, Mexico (68,000 sq ft, opened July 2024). The technical stack is vertically integrated, covering SMT assembly (to 510mm x 460mm board size at 20,200 CPH), through-hole assembly, in-house plastic injection molding (27 molding lines, 0.6-14 oz shot size), overmolding, waterproof interconnect assembly (IP67/IP68), and global sourcing through a network of 100+ qualified vendors, supported by certifications including ISO 13485, ISO 9001, IATF 16949, MedAccred, and ITAR.

The company employs approximately 500 staff globally and serves a primarily enterprise customer base — including Emerson Electric, Fortune 500 and Fortune 50 medical device OEMs, MicroSense, and unnamed aerospace and industrial automation customers — through direct field sales with named business development directors in the US and a sales manager in China, supplemented by industry trade show presence at MD&M West, BIOMEDevice Boston, and Robotics Summit & Expo. Revenue is generated through quote-based, project-priced contract manufacturing engagements for low-to-medium volume, high-mix production runs, alongside recurring revenue from custom supply programs (Min-Max, Kanban, VMI, Dock-to-Stock) and time-and-materials engineering and NPI services. Medical devices and healthcare represent approximately 50% of annual revenue with reported 25% growth over three years through 2021.

Since February 2023, Segue has operated as a subsidiary of Lorom Holding, which is backed by Cornell Capital LLC (~$6 billion AUM). In September 2023 Lorom merged with In-Tech Electronics, and in 2024 the combined group rebranded as Lisconn — an integrated platform of approximately 6,000 electronics professionals with operations across the US, China, India, Malaysia, and Mexico. Segue maintains its brand identity, headquarters leadership (CEO Brian Desmarais), and customer relationships within the Lisconn structure, contributing specialized cable and harness capabilities and NPI expertise to the broader platform's vertical-integrated electronics manufacturing services portfolio.
