Heart Aerospace US Relocation Impacts European Tech Innovation
Swedish electric aircraft firm Heart Aerospace moves to Los Angeles, highlighting Europe’s regulatory and funding challenges in scaling climate tech startups.
Why Heart Aerospace’s US Move Matters for European Tech
The relocation of Swedish electric aircraft startup Heart Aerospace to Los Angeles has sparked critical conversations about Europe’s ability to retain innovative companies. Founded in 2018 with ambitious plans to decarbonize regional air travel through its 30-seat ES-30 hybrid-electric plane, the company’s transatlantic shift comes at a pivotal moment. Heart Aerospace will lay off all 75 Swedish employees while expanding its US operations.
This move follows a growing pattern of European tech firms prioritizing American markets – 35% of EU-born unicorns now maintain dual HQs in the US according to Dealroom data. For climate tech specifically, US venture funding outpaced Europe 3:1 in 2024. Heart’s decision underscores structural challenges in scaling deep tech ventures within Europe, from regulatory complexity to risk-averse procurement markets.
The Strategic Shift to US Operations
Accelerating Development Through Proximity
CEO Anders Forslund cites “critical mass of expertise” as the driving factor, with 82% of Heart’s suppliers and 94% of committed airline customers (including United and Mesa Airlines) now based in North America. The company’s Los Angeles R&D center, opened in 2024, already employs 47 engineers working on battery systems and propulsion technology. Relocating leadership enables tighter integration between design teams and FAA certification processes ahead of the ES-30 prototype’s 2025 test flight.
Vertical integration emerges as another key rationale. Heart plans to bring 60% of component manufacturing in-house by 2026, leveraging California’s aerospace talent pool. “You can’t innovate at the speed required when relying on fragmented European supply chains,” explains Forslund. The move follows Airbus‘ 2024 decision to shift battery research to its US facilities, highlighting broader industry trends.
“Europe’s regulatory maze adds 18-24 months to certification timelines compared to FAA processes. For startups racing to prove technology viability, that difference is existential.” – Aerospace Industry Analyst Report 2025
Financial and Market Realities
While European investors provided early backing, the recent $40M funding injection came exclusively from US venture firms. Heart’s order book tells a similar story – 67% of its 250 firm orders originate from North American carriers versus 22% from European airlines. This commercial tilt mirrors wider aviation trends, with US regional airlines committing to 35% fleet electrification by 2035 compared to Europe’s 15% target.
The Swedish government’s investment now faces scrutiny. “Public funds shouldn’t subsidize corporate exits,” argues EU Parliament member Elsa Bergström. However, Heart maintains its Gothenburg R&D facility will remain operational through 2026, preserving some European ties.
Implications for Europe’s Tech Ecosystem
The Regulatory Innovation Gap
Europe’s CS-25 certification framework requires 147 separate compliance checks for new aircraft versus the FAA’s 89-point system. For hybrid propulsion systems, EASA mandates third-party validation of every component modification – a process venture capitalist Tobias Bengtsdahl calls “innovation suffocation by checklist.”
Contrast this with the FAA’s new Fast Track Electrification Program, offering 90-day turnaround on supplemental type certificates. Since its 2023 launch, 14 electric aviation projects have utilized this pathway compared to just two through EASA’s equivalent initiative.
“We’re not just losing companies – we’re losing entire technology categories. Europe invented electric flight with Airbus‘ E-Fan in 2014. Now the US and China dominate patent filings in this space.” – Dr. Lena Kortmann, TU Delft Aerospace Chair
Capital Markets and Scale-Up Challenges
Heart’s funding journey reveals structural gaps in European tech financing. While initial €50M came from EU climate funds and Nordic VCs, scaling required US institutional investors. European late-stage climate tech rounds averaged €75M in 2024 versus €210M in the US per PitchBook data.
Procurement practices exacerbate the issue. Scandinavian Airlines‘ letter of intent for 25 ES-30s includes an 18-month due diligence period, while United Airlines committed to 50 planes after a 90-day technical review. “European carriers want startups to have Boeing-level maturity before ordering,” notes Heart’s former VP of Sales.
Conclusion: Reversing the Innovation Exodus
Heart Aerospace’s relocation highlights urgent needs for regulatory modernization and risk-tolerant capital in Europe. While the EU’s Net Zero Industry Act allocates €45B for clean tech, bureaucratic hurdles continue delaying deployment. The European Commission’s proposed “Sandbox Europe” program – allowing temporary regulatory waivers for pilot projects – could help if implemented in 2026 as planned.
Industry experts suggest three key measures: harmonizing certification processes across EASA states, creating EU-wide procurement quotas for sustainable aviation tech, and establishing growth-stage investment vehicles with patient capital horizons. Without such reforms, Europe risks becoming a feeder system for US and Asian tech hubs rather than maintaining its own innovation ecosystems.
FAQ
Question: Why did Heart Aerospace choose Los Angeles over other US cities?
Answer: Proximity to aerospace suppliers, FAA headquarters, and major customers like United Airlines made Southern California strategically optimal.
Question: Will Heart Aerospace maintain any presence in Sweden?
Answer: The Gothenburg R&D facility remains operational through 2026, but all corporate functions are moving to LA.
Question: How does Europe’s regulatory environment compare for electric aviation?
Answer: EASA processes typically take twice as long as FAA certification, with more stringent documentation requirements for new technologies.
