Evergreen Additive

What Evergreen Additive does

Evergreen Additive, Inc. is a privately held advanced manufacturing company founded in 2025 as a spinout from the University of Maine's Advanced Structures and Composites Center. It operates a single facility at 74 Orion Street, Suite 102, Brunswick Landing, Brunswick, Maine, with 1–10 employees and is led by a four-person executive team comprising CEO Kyle Warren (former UMaine staff research leader, PhD Mechanical Engineering), COO Ben Steva, CFO Peter Drown, and CTO Andrew Gifford (formerly technical leadership at the largest U.S. supplier of recreational boats). The company's stated technology platform is Robotic Large Format Additive Manufacturing (LFAM) applied to fiber-reinforced composite materials, used to produce large marine structures — particularly tooling, molds, fixtures, and unmanned surface vessels — that would otherwise be built via labor-intensive, months-long composite layup processes.

The product portfolio is organized into three integrated offerings: Marine Composite Tooling Production (molds and fixtures for boat builders), Direct-use Unmanned Surface Vessels (defense platforms, including the two 6-meter USVs built and tested for the U.S. Navy), and Design for Additive Manufacturing (engineering services that optimize part geometry for LFAM). Revenue mechanics are project-based custom manufacturing engagements (described as one-time license / project services in the source data), with no disclosed pricing tiers and a consultative, low-pressure sales motion that explicitly avoids aggressive outbound tactics. The go-to-market is enterprise field sales targeting two primary segments: commercial maritime / boat builders and defense maritime programs, with the U.S. Navy as the only named customer logo and Indo-Pacific readiness cited as a strategic driver.

Capital structure is opaque. The company is incorporated in Maine, USA, has no disclosed parent, no identified institutional investors, no subsidiary entities, and no external funding round beyond an initial $1M equipment investment and a planned $5M capital investment over three years for the headquarters buildout. No revenue, ARR, or valuation has been disclosed, and certifications, patents, regulatory actions, and M&A activity are absent. Operating geography is currently North America (United States only), and the website explicitly markets the company as a 'Trusted manufacturing partner | Brunswick, Maine.'

Core offering

Evergreen Additive provides large-format additive manufacturing (LFAM) services for the maritime industrial base, using robotic composite fabrication to produce production molds and fixtures for boat builders as well as unmanned surface vessels for defense customers. The company delivers end-to-end solutions spanning Design for Additive Manufacturing engineering, tooling fabrication, and direct manufacture of defense platforms, with a focus on reducing lead times from months to weeks and lowering dependence on scarce skilled laminators.

Product overview

Evergreen Additive is a maritime-focused advanced manufacturing company offering a unified platform of large-format additive manufacturing (LFAM) solutions. The portfolio comprises three integrated offerings: Marine Composite Tooling Production (molds and fixtures for boat builders), Direct-use Unmanned Surface Vessels (defense platforms), and Design for Additive Manufacturing (engineering services). These capabilities are designed to work together as end-to-end solutions, addressing the full product lifecycle from initial design through final delivery, enabling rapid production of maritime tooling and vessels in weeks rather than months.

Functional benefit

Products and services

• Marine Composite Tooling Production Production of molds, fixtures, and jigs for boat builders using large-format additive manufacturing (LFAM). Enables near net-shape composite tooling with delivery in weeks rather than the 3-6 months required by traditional methods, reducing dependence on scarce skilled laminators. Targeted at commercial maritime customers and boat builders.
• Direct-use Unmanned Surface Vessels Direct manufacture of unmanned surface vessels (USVs) for maritime defense applications, including 6-meter platforms for the U.S. Navy. Produced using robotic LFAM systems to enable forward-deployed, rapid capability deployment for distributed maritime operations.
• Design for Additive Manufacturing Engineering services that optimize part and tooling designs for LFAM processes, providing end-to-end solutions from initial design through final delivery for maritime manufacturing customers.
