SBIR/STTR for Non-US Drone Companies: The Entity Path

The SBIR/STTR pipeline is one of the largest sources of non-dilutive R&D funding in the world — and it's structurally available to non-US drone companies that build the correct entity stack. The structural rules are not flexible, but they are well-defined, and the operational path from a foreign-domiciled drone company to an SBIR-eligible US small business is a path that's been walked many times. This is the 2026 guide for non-US drone founders who want the pathway done correctly.

The post draws on Dronehub's own path — Polish-engineered drone company, founder originally from Ukraine, dual-domicile structure with Dronehub Inc. (Delaware C-Corp, SBIR/STTR-eligible) and Dronehub Sp. z o.o. (Polish manufacturing entity). The same pattern is reproducible by any non-US drone company with the operational seriousness to commit to the US-side entity.

What SBIR and STTR actually are

SBIR (Small Business Innovation Research) and STTR (Small Business Technology Transfer) are US federal programmes that direct a defined percentage of participating agencies' extramural R&D budgets to qualifying small businesses. The participating agencies include the Department of Defense (the largest by award volume), NASA, the Department of Energy, the National Institutes of Health, the Department of Homeland Security, the National Science Foundation, and several others. The combined annual award volume is in the billions of dollars across all agencies.

The structural difference between SBIR and STTR is the research partnership requirement. SBIR is for small business R&D performed by the small business itself. STTR is for small business R&D performed in partnership with a non-profit research institution — a US university, a federal lab, or a non-profit research organisation — where the small business performs at least 40% of the work and the research institution at least 30%. The remaining 30% can flow to either side. STTR was created to push university-originated technology into commercial application via small-business partners.

For most drone-technology development, SBIR is the cleaner pathway. STTR fits when the underlying technology has academic-research origin and the team wants to preserve that academic partnership.

Both programmes run in three phases. Phase I is a feasibility study, typically $50,000 to $250,000 over 6 months, with the Department of Defense frequently awarding at the $250,000 cap. Phase II is R&D execution, typically $750,000 to $2 million over 24 months, with DoD frequently at the $1.5-2 million range. Phase III is commercialisation — Phase III is not directly funded by the SBIR programme, but the awardee retains sole-source contracting rights at the funding agency for Phase III work, which is where the long-tail commercial revenue from successful SBIR programmes actually lives.

The eligibility test: small business concern

To qualify for SBIR or STTR, the awardee must be a US-based for-profit small business concern (SBC). The SBC test has four pieces.

Size. The SBC must have 500 or fewer employees, including affiliates. Affiliate counting is broader than direct employees — entities under common control or common ownership count toward the cap.

Ownership. More than 50% of the SBC must be directly owned and controlled by US citizens or permanent residents, OR more than 50% must be owned and controlled by other US SBCs that themselves meet the ownership test. The SBC-to-SBC pathway permits limited indirect ownership but the chain has to terminate in US-citizen/PR ownership.

Control. The 'controlled' test goes beyond pure equity. The SBA examines voting rights, board composition, operational decision authority, and whether the management team operates independently of foreign ownership. A nominally US-majority-owned entity that's operationally directed by a foreign parent fails the control test even if it passes the ownership test.

US operations. The work funded by the SBIR award must be performed in the United States by the SBC, with limited exceptions for specific technical components that genuinely cannot be performed in the US (and even those exceptions require explicit agency approval).

For a non-US drone company, the practical translation is: you need a US-domiciled subsidiary or related entity (typically a Delaware C-Corp), with US employees, US-based operations, and more than 50% US-citizen or permanent-resident ownership. The foreign parent or foreign founder can hold a minority position or be reorganised under a US-side holding structure.

The Delaware C-Corp pattern

Delaware C-Corp is the predominant entity structure for SBIR-eligible companies. The choice is driven by three things and not by SBIR itself.

First, investor compatibility. Most US institutional investors — venture capital, corporate venture, defense-focused growth funds — expect Delaware C-Corp structures because the corporate law is mature and predictable. Foreign-domiciled entities create due-diligence friction that delays or breaks investor processes. The C-Corp structure is the investor-side default.

Second, the C-Corp's separation of ownership and operations. The C-Corp creates a clean separation between the equity holders (shareholders) and the operational management (officers, directors). This separation matters for SBIR's control test — the C-Corp can hold equity in a structure that satisfies the 50%+ US rule while the operational management operates under a US-citizen/PR officer team. The structure permits clean SBC compliance without forcing the founder to dilute below founder-equity levels.

Third, alignment with the standard equity structures the programmes expect. The SBIR programme office, the agency contracting officers, and the diligence panel are accustomed to evaluating C-Corp structures. Non-standard structures (LLCs in non-Delaware jurisdictions, foreign-domiciled affiliates) trigger extended review cycles that delay award.

For Dronehub, the structure is: Dronehub Inc., Delaware C-Corp, SBIR/STTR-eligible US small business. Operational base in the Research Triangle, North Carolina — chosen for co-location with the federal-innovation cluster (RTP), the defense corridor (Fort Liberty), and the academic infrastructure (Duke, UNC, NC State). The Polish entity, Dronehub Sp. z o.o., handles manufacturing at the Jasionka factory in Aviation Valley. The two entities operate under a clean parent-subsidiary relationship that satisfies both SBIR control requirements and EU defense industrial strategy alignment.

The founder-residency layer

The SBIR ownership test references US citizens or permanent residents. For a non-US founder, the practical question is which US residency pathway to pursue, and on what timeline.

EB1A — Extraordinary Ability green card. EB1A is the cleanest pathway because it produces permanent residency directly, without employer tethering, on the basis of the founder's individual record. The evidence requirements are demanding — the applicant has to demonstrate national or international acclaim in their field through a structured set of categorical criteria (awards, published material, judging panels, contributions to the field, original work of major significance, etc.). For drone-technology founders with substantial public records — EU consortium leadership, industry recognitions, Forbes-style media coverage, technical publications, panel appearances — the evidence pack can be assembled. The process takes 6-18 months depending on agency backlog.

O-1 — Extraordinary Ability nonimmigrant visa. O-1 has lower evidence requirements than EB1A but is employer-tethered (the visa attaches to a specific US employer that sponsors the applicant). For a founder, the sponsoring employer is typically the founder's own Delaware C-Corp, which creates a circular structure that the USCIS has accepted in many cases but reviews carefully. O-1 is faster to obtain than EB1A but does not produce permanent residency directly.

E-2 — Treaty Investor visa. E-2 is available to nationals of treaty countries (most NATO members, with notable exceptions including Russia). E-2 requires a substantial US investment by the treaty national and the establishment of a US business that's not marginal. The visa permits long stays but does not produce permanent residency directly. For drone founders from NATO Europe (Poland, Czech Republic, Germany, France, the Nordic cluster, the UK), E-2 is a practical fast-track if EB1A or O-1 evidence isn't ready.

L-1 — Intracompany transfer. L-1 works if the founder has been employed by the foreign parent in an executive (L-1A) or specialised-knowledge (L-1B) role. The visa transfers the founder to the US-side subsidiary as an executive or specialist. L-1A leads to a relatively straightforward EB1C green-card path after a year of US employment. For founders running their own foreign-parent companies for several years before US expansion, L-1A is often the cleanest.

For Dronehub: founder Vadym Melnyk secured EB1A (Extraordinary Ability green card) — the EB1A evidence pack was assembled from EU consortium-leadership credentials, Forbes Polska and Forbes Ukraine recognitions, industry-panel work, and the deployed programme portfolio (HUUVER, AUDROS, Deutsche Bahn, UAV Nomad). The founder vetting that the SBIR control test references is permanently resolved at the personal level.

The foreign-affiliation disclosure layer

The SBIR Extension Act of 2022 added foreign-affiliation disclosure requirements that materially affect non-US drone companies pursuing SBIR.

Under the 2022 reauthorization, SBIR applicants must disclose any affiliations with foreign entities — particularly with countries the US government designates as foreign countries of concern (China, Russia, Iran, North Korea, and a small additional list). Companies with substantial ties to covered countries face SBIR participation restrictions ranging from denial of award to extended review cycles.

For non-US drone companies from NATO-allied jurisdictions, the foreign-affiliation rule is not a barrier — it's a clearance check. A Polish-domiciled parent with no China/Russia/Iran/North-Korea ties passes the disclosure with documentation. A Czech-domiciled parent passes the same way. A German-domiciled parent passes. The structural test isn't about being non-US; it's about being structured cleanly relative to the covered-country list.

For Dronehub specifically: Polish parent entity, Ukrainian founder, NATO-allied supply chain, zero CN/RU/IR/NK ties across the bill of materials, EU + US data sovereignty by architecture, EDIS-aligned industrial strategy. The foreign-affiliation disclosure resolves cleanly.

What the SBIR pipeline actually feels like once you're in

For non-US drone founders evaluating whether to commit to the entity build, it's worth understanding what the SBIR pipeline operationally looks like once the entity is in place.

Phase I awards are competed against agency-published topic windows. Topics rotate — DoD agencies open topic-windows multiple times per year, with Open Topics from AFWERX (USAF/USSF) and Direct-to-Phase-II pathways from DIU providing additional flexibility. The Phase I award packs the proposal, the technical pack, the commercialisation plan, and the SBC compliance attestation. Award notification is typically 3-6 months after submission. Phase I execution is 6 months.

Phase II awards are competed by Phase I awardees — Phase II is not generally open to non-Phase-I companies. The Phase II proposal builds on Phase I results, with a substantially deeper technical and commercialisation pack. Award notification is 3-6 months after submission; execution is 24 months. Phase II is where the real R&D budget lives.

Phase III is commercialisation. The awardee retains sole-source contracting rights at the funding agency for Phase III work, which means the long-tail revenue from a successful SBIR programme can be substantially larger than the Phase I and Phase II amounts combined — Phase III contracts can run to tens of millions of dollars for proven technologies in agency-priority topic areas.

For Dronehub: the portfolio (counter-UAS interception, drone-in-a-box persistent coverage, hybrid UAV-UGV with cryptographically authenticated positioning, AI rail and infrastructure inspection, mobile-dock convoy escort) maps directly to active SBIR topic areas across DoD agencies, NASA, DHS, and DoE.

What this means for non-US drone founders

For European drone companies considering US market entry — the entity path is established, the structural requirements are well-defined, and the founder-residency pathway has multiple viable options depending on personal credentials. The investment is months of operational setup and serious commitment to US-side substance; the return is access to one of the largest non-dilutive R&D funding pipelines in the world and the federal-procurement pathway that follows.

For Israeli, Canadian, UK, Japanese, Korean, and Australian drone companies — the same pathway works. The structural requirements are nation-neutral within the NATO-allied / treaty-partner set. The foreign-affiliation rule is a clearance check, not a barrier, for companies structured cleanly.

For Polish, Czech, Baltic, and Eastern European drone companies — the same pathway works with the additional structural advantage that EDIS-aligned manufacturing in the home country pairs naturally with US federal innovation procurement on the other side. The dual-domicile structure that Dronehub runs is reproducible.
