The new space economy, often described as the small business in space movement, is not just about launching satellites or selling advanced technology. It is about building a connected network where innovation sparks collaboration and collaboration drives meaningful progress. Many companies enter this sector with breakthrough ideas capable of transforming industries, enhancing connectivity, and expanding the boundaries of exploration. Yet even the most promising ventures soon realize that success depends less on selling a product and more on the ecosystem that sustains it. In this new reality, organizations are no longer focused on selling a product in space but on delivering a complete service that integrates technology, customers, and long-term value.

Access to technical collaborators, institutional support, and customers who can recognize and value innovative solutions is essential. Without these connections, even revolutionary technologies may struggle to scale effectively. Navigating this complex landscape requires vision, patience, and the ability to foster enduring relationships across borders and industries.

Amid this challenging environment, 3i3Signature LLC has emerged as a trusted enabler for European and American New Space startups, as well as established aerospace companies. Founded by Philippe Boissat, a former global aerospace and defense executive with Deloitte, the company specializes in helping organizations navigate international expansion, build meaningful collaborations, and gain visibility with the right clients.

By working closely with the European Space Agency (ESA) and NASA, 3i3Signature LLC ensures that its clients can overcome regulatory hurdles, establish local operations, and position themselves for sustained growth. Its work spans small innovators with disruptive technologies to large aerospace groups such as Boeing and SpaceX. The company also collaborates with new aviation ventures developing electric, hybrid, and hydrogen-powered solutions, supporting innovation across the spectrum of space-related industries.

“Many businesses make the mistake of trying to sell products immediately,” says Boissat. “The right approach is to build a strong ecosystem first. Alone, even the most inventive business can achieve very little. By fostering technical, institutional, and financial collaborations, organizations can create solutions that attract and retain customers over the long term.”

A Three-Step Approach to Growth

3i3Signature LLC structures its services around a clear three-step approach designed to help clients maximize their impact.

The first step, understanding and visibility, involves assessing a firm’s positioning and communication strategy. The team reviews messaging clarity, website effectiveness, and whether potential customers understand the value being offered. By aligning objectives and refining the value proposition, 3i3Signature LLC establishes a foundation for all subsequent initiatives. This ensures that clients communicate confidently, present offerings effectively, and build credibility from the outset.

The second step focuses on building connections. Once goals are defined, the company helps clients engage with technical collaborators, institutional stakeholders, and financial partners such as family offices or specialized funds. These relationships integrate companies into a wider ecosystem, boosting credibility and accelerating market entry. By fostering partnerships, organizations can offer comprehensive solutions rather than isolated products. This is increasingly important in the New Space sector, where customers demand integrated offerings.
The third step is business development and market access. With a strong foundation and robust network in place, 3i3Signature LLC assists clients in engaging high-value customers, navigating regulatory complexity, and obtaining institutional approvals. By combining strategic guidance with hands-on operational support, the firm helps companies demonstrate the practical value of their innovations and achieve measurable growth. This ensures that solutions reach the right markets and scale sustainably.

Proven Results across Continents

Since 2022, 3i3Signature LLC has helped nearly 35 European companies establish operations in the United States, with France alone contributing over 10 organizations in the past three years. Overall, the firm has supported 57 start-ups in two and a half years across Germany, Spain, Italy, and France. Facilitating the entry of U.S. start-ups into Europe has proven more challenging due to regulatory differences and market dynamics, yet the company has successfully assisted several ventures while providing guidance for larger aerospace groups.

Client success stories highlight 3i3Signature’s impact. One startup developing antenna technology for satellites and rockets now has a strong presence in both Europe and the United States. Another startup that specializes in weather monitoring applications in space, is offering critical observational data. Another business is advancing infrared and fiber-optic communications for orbital systems. These examples demonstrate how 3i3Signature LLC transforms technical innovation into commercially viable offerings while connecting clients to the right partners and markets.

The company’s work extends beyond civil applications, collaborating with NATO, the U.S. Air Force, and European defense organizations. Supporting ventures across multiple domains strengthens the ecosystem of space innovation and ensures that clients are prepared for both commercial and defense markets.

Building the Future of Space

3i3Signature LLC is expanding its team to at least ten consultants, each focused on European New Space startups. These consultants provide hands-on guidance to help organizations innovate, replace rapidly, and respond to market opportunities. The company emphasizes high-growth sectors such as telecommunications, which accounts for nearly 80 percent of demand, Earth observation at 15 percent, and geolocation at five percent. By aligning clients with these areas, 3i3Signature LLC ensures they remain relevant and well-positioned in the market.

Transatlantic collaboration is a central focus. Despite shared technical capabilities and innovative mindsets, cooperation between European and U.S. space enterprises remains limited—3i3Signature LLC bridges this gap, enabling European startups to access U.S. institutions and vice versa. Projects related to NASA’s Artemis program showcase the value of European expertise in global initiatives. By connecting companies across continents, the firm accelerates innovation, expands market opportunities, and fosters knowledge exchange and collaboration.

A Partner for Lasting Impact

At its core, 3i3Signature LLC is more than a consulting company. It is a partner that helps organizations navigate the complex and competitive space sector. Through a pragmatic approach, deep technical expertise, and a robust network, the company enables startups and established firms to turn ambitious ideas into practical solutions with tangible results. By focusing on ecosystem building rather than individual products, 3i3Signature ensures that clients attract and retain customers over the long term.

From advanced antennas for launchers or satellites enhancing satellite communications to sophisticated weather monitoring platforms and high-performance communication systems, the company’s clients are defining the next era of space exploration. By guiding ventures through regulatory, technical, and market challenges, 3i3Signature LLC ensures that innovations scale effectively, creating lasting value for customers and the broader space community. Its ongoing work across both civil and military sectors positions 3i3Signature LLC as a critical enabler in the New Space economy, supporting startups that aim to transform how humanity observes, communicates, and operates in space.
