Why Defence Companies Need More Than Innovation to Scale

The global defence landscape is undergoing one of its most significant transformations in decades. Russia's invasion of Ukraine, escalating tensions in the Middle East, increasing strategic competition in the Indo-Pacific and renewed commitments by NATO members to strengthen defence capabilities have reshaped government priorities worldwide. As nations accelerate investment in security, resilience and sovereign manufacturing, defence is no longer viewed solely through a military lens. It has become a strategic industrial priority, creating unprecedented opportunities for companies developing the technologies, infrastructure and manufacturing capabilities that will define the future of defence.

The next generation of defence companies is being built. As governments increase defence spending and investors turn their attention to the sector, the question is no longer whether opportunities exist, but whether innovative businesses have the right capital to seize them. For defence businesses, this represents far more than increased government spending. It signals a structural shift in how innovation is funded, commercialised and scaled.

It also reflects a significant shift in how investors view the sector. While some institutional investors historically took a cautious approach to defence, the sector is increasingly recognised as a driver of technological innovation, economic resilience and national security, attracting growing interest from institutional and private capital alike.

For decades, the sector was dominated by a small number of established prime contractors, large government programmes and traditional procurement models. Today, that landscape is changing rapidly. Artificial intelligence, autonomous systems, advanced manufacturing, cyber security, space technology and dual-use technologies are reshaping how nations think about security and resilience.

Behind this transformation is a new generation of defence companies developing critical capabilities. From AI-powered intelligence platforms and autonomous drones to advanced materials and next-generation manufacturing, innovation is accelerating across the ecosystem. Many of these businesses sit outside the traditional defence primes, developing specialised technologies and manufacturing capabilities that are increasingly critical to national security.

Innovation alone does not build a successful defence business. Scaling requires capital that understands the sector's complexity, long sales cycles and unique funding requirements.

Global defence spending reached approximately $2.9 trillion in 2025, marking the 11th consecutive year of growth. European defence expenditure increased significantly, with regional spending rising by 14% year-on-year, reflecting a broader shift towards strengthening sovereign defence capabilities and reducing dependency on external supply chains.

These themes were also explored during Fuse Capital Group's recent unlock the defence market: SME playbook webinar, where industry experts discussed the evolving defence landscape, the opportunities emerging for SMEs, and the practical considerations for businesses looking to scale in a rapidly changing market. As defence spending continues to rise, understanding how to fund growth is becoming just as important as developing innovative technologies.

While this investment is creating significant opportunities for defence technology companies, manufacturers and specialist suppliers, it is also exposing a critical challenge. Businesses need access to capital that can keep pace with their growth ambitions. As governments commit to long-term defence investment, private sector businesses across the supply chain are increasingly being called upon to innovate, scale production and strengthen industrial capability. The challenge is ensuring these businesses have access to the right funding at the right stage of growth.

Defence innovation is accelerating, but traditional funding does not always fit

Many defence businesses are profitable, technologically advanced and commercially viable, yet still encounter challenges when raising capital. As we explored in our article on the financeability gap, lenders assess far more than revenue or profitability. Factors such as contract visibility, procurement cycles, asset quality and cash flow resilience all influence how financeable a business appears, making preparation just as important as performance.

Defence companies often operate differently from businesses in other high-growth sectors.

Product development cycles can be longer. Procurement processes can involve extensive testing, certification, and government approvals. Revenue visibility may depend on contracts that take months or years to convert. Meanwhile, companies may need significant upfront investment in engineering talent, specialist equipment, manufacturing capacity, and supply chain development.

For early-stage companies, venture capital can provide growth capital. However, as businesses mature, many founders and management teams face a different challenge: how to scale without excessive dilution or relying solely on equity fundraising.

This is where capital strategy becomes just as important as technology strategy. Identifying the right funding solution requires an understanding of both the business and the lenders most suited to support it.

Unlike many high-growth sectors, defence businesses often have valuable assets, long-term contracts, predictable revenue pipelines and specialist equipment that can strengthen their borrowing profile. These characteristics can make private debt an attractive source of capital when structured appropriately. For businesses with significant manufacturing equipment, machinery, inventory or contracted future cash flows, the right financing solution, including asset-backed financing where appropriate, can unlock additional capital without relying solely on equity. This allows founders to preserve ownership while accessing the liquidity needed to invest in growth, fulfil larger contracts or expand into new markets.

In some circumstances, founders may also be able to unlock liquidity by borrowing against the value of their shareholding rather than selling equity. As discussed in your shares are worth millions, borrow against them, this can provide access to capital while maintaining long-term ownership and strategic control.

Unlike traditional bank lending, private debt solutions can be structured around the specific characteristics of growth businesses rather than relying solely on conventional lending criteria. For defence companies, this can include funding for working capital, equipment investment, contract execution, acquisitions or international expansion, giving businesses greater flexibility to pursue growth without unnecessary equity dilution.

Defence is becoming an investment opportunity, not just a strategic priority

The rise of defence technology has attracted increasing attention from investors. Companies developing AI-enabled defence systems, autonomous platforms, and security infrastructure are seeing significant interest from specialist investors and institutional capital.

This growing investor confidence reflects a broader recognition that defence innovation extends well beyond traditional military equipment. Software, cyber security, artificial intelligence, advanced manufacturing and dual-use technologies are becoming increasingly central to the future of the sector, creating new opportunities for both businesses and capital providers.

Recent investment activity reflects this momentum. European defence technology companies have attracted substantial investment as investors look to support technologies aligned with national security priorities and emerging geopolitical requirements.

However, capital alone is not enough. Defence businesses require investors and advisers who understand the commercial realities of the sector. A company with strong technology may still face challenges around procurement cycles, customer concentration, export restrictions, manufacturing scalability, or contract timing.

Understanding these factors is essential when structuring financing solutions.

What funding options are available to defence companies?

There is no single funding solution for every defence business. The right approach depends on factors such as growth stage, contract pipeline, asset base and long-term objectives. While some businesses may benefit from working capital facilities or equipment finance, others may be better suited to asset-backed lending, acquisition finance, venture debt or structured private credit. The most effective funding strategies align capital with commercial milestones rather than relying on a one-size-fits-all approach.

Why private debt is becoming a strategic funding tool for defence companies

As defence companies scale, their funding requirements become increasingly complex.

A growing defence manufacturer may need capital to purchase equipment, expand production capacity, secure inventory, or fulfil a large customer contract. A defence technology company may need funding to bridge the gap between product development and commercial deployment. A supplier within the defence ecosystem may require working capital to support larger orders from established contractors.

Private debt can provide a more flexible source of capital by aligning funding structures with future growth plans and business milestones rather than relying solely on historical performance.

For asset-heavy businesses, asset-backed lending can unlock value from equipment, machinery, inventory, and other tangible assets. For high-growth technology companies, venture debt or structured private credit solutions can provide additional runway while reducing immediate equity dilution.

The key is not simply accessing capital, but designing the right capital strategy for the company's growth journey.

As funding requirements become more sophisticated, choosing the right funding structure is just as important as choosing the right funding source. This is where experienced private debt advisers can add significant value by helping businesses evaluate their options, structure the right financing solution and connect with lenders that understand their objectives.

Scaling a defence business requires more than innovative technology. It requires a capital strategy that evolves with your business.

Before approaching lenders or investors, businesses should also assess how prepared they are for the funding process. Our debt readiness checklist outlines the key questions every leadership team should consider before pursuing growth capital, acquisitions or strategic investment, helping businesses identify potential gaps before engaging the market.

As the defence ecosystem continues to mature, businesses with access to flexible private capital will be better positioned to commercialise innovation and scale sustainably.

Defence companies need partners who understand both capital and complexity

The future of defence will not be built by technology alone. It will be built by companies that can successfully commercialise innovation, scale operations and deliver critical capabilities at speed. Achieving that requires a funding ecosystem capable of supporting businesses through every stage of growth.

The future of defence is being funded today, and the businesses that secure the right capital will be best placed to lead tomorrow. Whether you're scaling production, investing in advanced technology, fulfilling larger contracts or expanding internationally, the right funding strategy can become a competitive advantage.

The businesses that will define the next generation of defence are not simply those with the strongest technology. They will be the organisations that combine innovation with a well-structured capital strategy, enabling them to invest confidently, fulfil larger contracts and respond quickly as opportunities emerge in an increasingly dynamic global market.
