Sintavia secures $10m from Stifel North Atlantic AM-Forward Fund to advance aerospace manufacturing

Sintavia, LLC, a global leader in aerospace component manufacturing, has announced a significant financial milestone, securing a $10 million subordinated debt investment from the Stifel North Atlantic AM-Forward Fund. This investment will play a crucial role in supporting the company’s continued growth, with capital earmarked for refinancing existing equipment loans and bolstering general working capital.

The funding represents the inaugural investment of the recently launched SBIC (Small Business Investment Company) fund, managed by North Atlantic Capital Management, a wholly owned subsidiary of Stifel Financial Corp. The fund focuses on enhancing advanced manufacturing capabilities within the U.S. aerospace and defense sectors, with a particular emphasis on expanding additive manufacturing technology across the domestic supply chain.

How will the $10 million investment impact Sintavia’s growth?

The $10 million injection is expected to accelerate Sintavia’s operational capabilities, strengthening its position as a leader in the additive manufacturing technology landscape. The company, known for its vertically integrated approach, combines design, additive manufacturing, and post-processing into a seamless digital production thread. This method has allowed Sintavia to produce next-generation power and thermodynamic components, such as heat exchangers, combustors, and pumps, for global aerospace and defense leaders.

Brian R. Neff, Founder and CEO of Sintavia, expressed his enthusiasm about the investment, stating that it highlights growing confidence in the potential of additive manufacturing technology. According to Neff, the partnership with Stifel will not only provide financial backing but also strategic support as the company continues to innovate in aerospace and defense manufacturing.

“This investment reflects Stifel’s strong commitment to funding profitable, high-growth companies leveraging additive technology. We are honored to be the launch investment of this new fund, which will undoubtedly create a positive ripple effect across the entire industry,” said Neff.

Why did Stifel North Atlantic AM-Forward Fund choose Sintavia?

The decision to invest in Sintavia aligns with the fund’s mission to support small business manufacturers that are driving advancements in aerospace component manufacturing. Mark Morrissette, Managing Director of North Atlantic Capital, highlighted Sintavia’s leadership in the additive manufacturing sector as a key factor behind the investment.

“Sintavia is an ideal fit for the mission of our fund. Brian Neff has proven to be a visionary leader, not just for Sintavia but for the additive manufacturing industry as a whole. Since 2015, Sintavia has demonstrated exceptional growth, building a vertically integrated, all-digital aerospace component supplier that leverages the transformative power of additive technology,” said Morrissette.

Morrissette’s appointment to Sintavia’s board of directors, as part of the investment agreement, further solidifies the strategic partnership between the two organizations.

What role does additive manufacturing play in Sintavia’s success?

Additive manufacturing, also known as 3D printing, has been a game-changer for aerospace and defense industries. It enables the production of complex components with greater efficiency, reduced material waste, and enhanced performance. Sintavia’s expertise in additive manufacturing technology has led to groundbreaking achievements, including the production of the first metal AM components installed on a fighter jet and a nuclear-powered submarine.

In December 2024, Sintavia collaborated with Curtiss-Wright‘s Engineered Pump Division (EPD) and Bechtel Plant Machinery Inc. (BPMI) to deliver the first additively manufactured impeller for installation in a U.S. Navy submarine. This milestone demonstrated the potential of additive manufacturing to enhance the performance and reliability of mission-critical naval defense components.

David Micha, Senior Vice President and General Manager of Curtiss-Wright’s EMS Division, praised Sintavia’s contributions to the project, stating, “Sintavia has proven to be an invaluable industry partner. We are excited to expand our collaboration and increase the number of additively manufactured parts for critical naval defense applications.”

How will Sintavia’s expansion plans shape its future?

The $10 million investment comes on the heels of Sintavia’s ambitious $25 million expansion plan, announced in 2024. This plan focuses on scaling the company’s operations, including investments in new facilities, larger industrial 3D printers, and advanced post-processing equipment. The new facility, which became operational in January 2025, is designed to meet the growing demand for additively manufactured components in aerospace and defense applications.

Lindsay Lewis, Corporate Vice President at Sintavia, emphasized the strategic importance of this expansion, noting that it will enable the company to stay ahead of industry trends and continue delivering high-quality components to its global clients.

“Additive manufacturing technology is reshaping the landscape of aerospace and defense production. As demand for innovative, high-performance components increases, our expanded capabilities will allow us to meet these needs with greater efficiency and precision,” said Lewis.

What’s next for Sintavia and additive manufacturing?

As the aerospace and defense sectors continue to evolve, the demand for advanced manufacturing solutions is expected to grow. Sintavia’s partnership with Stifel North Atlantic AM-Forward Fund positions the company to capitalise on this trend, further cementing its role as a leader in the field of aerospace component manufacturing.

The investment will not only support Sintavia’s operational growth but also foster innovation in the development of next-generation defense components. With a strong focus on sustainability, efficiency, and performance, additive manufacturing is set to play a pivotal role in shaping the future of aerospace and defense technologies.

For Sintavia, this is just the beginning of an exciting new chapter—one where cutting-edge technology meets strategic investment to redefine the boundaries of what’s possible in aerospace manufacturing.
