Frankenburg Technologies
Frankenburg Technologies builds low-cost, AI-enabled counter-drone interceptor missiles (Mark I) for mass production using commercial components, targeting European SHORAD gaps.
Background
Founded in 2024 in Tallinn, Estonia, by Taavi Madiberk and Marko Virkebau, Frankenburg Technologies was built around the premise that Western air-defense gaps — exposed sharply by drone warfare in Ukraine — could be closed with affordable, mass-manufacturable interceptors rather than legacy high-cost missiles.
CEO Kusti Salm, former Permanent Secretary of the Estonian Ministry of Defence, joined to lead the company's scaling and institutional engagement.
The company's flagship product is the Mark I interceptor missile, a short-range air-defense munition designed for counter-UAS and SHORAD roles.
The Mark I is built using commercially available components integrated with AI targeting to reduce unit cost and accelerate production timelines without dependence on traditional defense-industrial supply chains.
Frankenburg operates across Estonia, Latvia, Lithuania, Denmark, Germany, Poland, the UK, and Ukraine. Its own careers page reports 80 staff.
The company has established a UK headquarters alongside its Tallinn base and Latvian operations, reflecting a deliberate multi-jurisdiction manufacturing and regulatory strategy targeting both NATO procurement channels and Ukraine urgent-supply pipelines.
Financial footing
- €30M Series A (early 2026, Plural)
- ~€40M total
- "$50M @ $400M val" reported (single-source, uncertain)
- MoU Hanwha Aerospace (Feb 2026)
- PGZ Poland production deal (Mar 2026)
- Backers: Plural (lead), SmartCap Defence Fund
Frankenburg raised approximately €1.5 million in a seed round in late 2024 at a €55 million valuation. A subsequent €4 million round pushed the valuation to €150 million. On 24 February 2026, the company closed a €30 million Series A led by Plural, with SmartCap Defence Fund participating, bringing total disclosed funding to €40 million against a €150 million valuation.
A separate single-source report cited a $50 million raise at a $400 million valuation — that figure is unverified and should be treated with caution. Frankenburg remains privately held. No revenue figures or order backlog have been publicly disclosed. The MoU with Hanwha Aerospace signed in February 2026 and the PGZ production framework signed in March 2026 carry no publicly disclosed financial terms.
Major customers & contracts
The Latvian Ministry of Defence announced an R&D contract with Frankenburg to develop, test, and supply Mark I air-defense missiles to Latvian forces — the most clearly documented government procurement relationship to date. In March 2026, Frankenburg signed a framework production agreement with PGZ, Poland's state defense industrial group, covering joint development and manufacture of counter-UAS and air-defense solutions; no contract ceiling has been disclosed.
Colt CZ Group signed a defence cooperation agreement with Frankenburg, explicitly referencing support for Ukraine's access to attritable interceptors and expansion of European air-defense capacity, though this is structured as cooperation rather than a finalized procurement contract. In February 2026, Frankenburg signed an MoU with BAE Systems covering scale-up of UK sovereign missile production, warhead co-development, and supply-chain collaboration for low-cost missile systems.

Competitive position
Frankenburg competes primarily in the emerging mass-producible counter-UAS interceptor segment, not against legacy SHORAD primes. Against Rheinmetall's Skyranger and MBDA's Mistral-family systems, Frankenburg's edge is radically lower unit cost and faster production ramp using commercial components; its weakness is the absence of a fully qualified, combat-proven system at scale. Against U.S. startups such as Anduril (Roadrunner) and Epirus, Frankenburg holds a European-sovereign-production narrative that resonates with NATO member procurement offices prioritizing non-U.S.
supply chains post-2025; the gap is Anduril's far larger capitalization and U.S. government customer base. Against fellow European entrant Helsing, which focuses on AI software layers for existing platforms, Frankenburg is the full hardware-plus-AI stack, giving it a more defensible product identity but a heavier manufacturing burden. The structural market condition — NATO members urgently procuring SHORAD after Ukraine — favors any credible entrant, compressing Frankenburg's window to prove the Mark I before better-resourced competitors reach similar price points.
Battlefield relevance
Plural stated publicly that Frankenburg's Mark I system is "being deployed in Ukraine" in 2026, and company and partner materials consistently describe Ukraine as an active operational or deployment location. The Colt CZ cooperation agreement explicitly references Ukraine access to attritable interceptors. However, no independently confirmed combat-performance report, battle-loss record, specific unit operator, or documented intercept count has been made public as of mid-2026.
The Latvia MoD R&D contract covers development, testing, and supply, indicating the system is not yet in full Latvian operational service. Deployment status in Ukraine should be treated as asserted by the company and lead investor but not yet independently verified through government or open-source operational reporting.
