- InSpacePropulsion Technologies
Led · Seed · Feb 2026
InSpacePropulsion Technologies (ISPTech) is a German space-tech company focused on propulsion hardware that replaces toxic hydrazine thrusters with safer, high-performance alternatives. Its product line includes the HyNOx and HIP_11 systems, which are designed to deliver high thrust and rapid responsiveness for collision avoidance, orbit changes, and other complex satellite maneuvers. The company is expanding commercial engagement with satellite manufacturers, defence customers, and in-orbit service providers. Two customer missions are currently in preparation, with the first small-satellite launch using ISPTech propulsion planned for 2026, while CubeSat units are already in acceptance testing. ESA-supported projects are helping advance HIP_11 and an orbital refuelling initiative. By enabling more flexible spacecraft mobility, ISPTech aims to underpin future growth in satellite constellations and in-orbit services.
- enclaive
Led · Seed · Feb 2026
enclaive develops a confidential computing platform that lets organisations deploy applications inside secure enclaves across multiple clouds, ensuring data remains shielded even while it is being processed. The vendor-agnostic architecture supports Kubernetes clusters, virtual machines, and AI workloads without requiring any modifications to existing code, tools, or workflows. By removing the need to fully trust cloud providers, the company targets highly regulated sectors such as finance, healthcare, public services, critical infrastructure, and AI model deployment. enclaive positions its technology as a response to growing AI adoption, stricter data-protection regulations, and increasingly sophisticated cyber threats. The platform’s modular design aims to simplify deployment and give enterprises granular operational control. Fueled by its recent seed financing, the company plans to accelerate commercial growth, advance development of its eMCP platform, enlarge its engineering and operations teams, and begin international expansion.
- Futuriza
Participated · Seed · Jan 2026
Founded a little over a year and a half ago in Joinville, Futuriza tackles the high cost and slow turnaround of traditional fashion photo shoots by offering an AI platform with more than 100 automated, plug-and-play steps that create visual content for entire collections. The system enables brands to launch products faster while cutting production costs. In 2025 the company produced over 30,000 images and videos for clients such as Farm, Hering, Brandili and Lez a Lez. Management is led by CEO Felipe Silva and CTPO Diogo Máximo, alongside COO Sariane Serafim and Head of Product Milena Moser. The startup operates from bases in Joinville, Vitória (ES) and Florida, and it has begun a U.S. pilot with children’s brand Monica + Andy. With fresh capital, Futuriza plans to scale its presence in North America and further refine its AI pipelines. Prior to the current raise, Antler injected US$125,000 in a 2024 pre-seed round.
- Hypercritical
Led · Seed · Dec 2025
Hypercritical develops foundation models that act as domain-specific agents capable of independently designing, verifying, and optimising control software within strict, mathematically defined safety limits. Its flagship product, Hyperpilot, and a suite of domain-specific “copilots” enable engineers in automotive, aerospace, defence, and robotics to specify tests rather than write code, after which the AI produces software that satisfies 100% of requirements. By eliminating hallucinations and errors, the platform delivers faster, more cost-effective, and fully correct outputs essential for industries where reliability is non-negotiable. The company envisions its methods becoming part of ISO certification standards, positioning its technology as the benchmark for generating control software globally. Components of its stack are already deployed with customers in real-world safety-critical environments, validating its approach. Hypercritical has raised £2 million in pre-seed funding, and while it has not disclosed revenue or user counts, the fresh capital underscores investor confidence. Post-funding, the startup plans to double its workforce and invest heavily in cloud compute to train its proprietary model. These initiatives aim to accelerate product development and expand adoption across heavy industry.
- Kreios Space
Led · Seed · Sep 2025
Founded in 2021 and headquartered in Vigo, Kreios Space is building an Air-Breathing Electric Propulsion (ABEP) engine that ingests atmospheric air, converts it to plasma, and powers satellites without the need for onboard propellant. The technology is designed to keep spacecraft flying at altitudes of 150–400 km, where they can deliver three-times-higher image resolution and enable direct-to-device broadband connectivity. The company plans to use its new capital to test the ABEP engine in orbit and launch its first two VLEO satellites, followed by commercial Earth-observation and broadband constellations. Kreios’ 17-person team includes talent drawn from Thales, JAXA and the European Space Agency and has received support from Spain’s CDTI and Spanish Space Agency under the National Space Technology Programme. Strategically, the startup positions Europe for greater autonomy in space infrastructure while targeting applications such as wildfire detection, infrastructure monitoring, defence and disaster response. Financially, Kreios has now raised €10.3 million in total, including the latest €8 million seed round and a prior €2.3 million tranche closed earlier in 2024. The fresh funds will accelerate hardware development, orbital demonstration and subsequent commercial deployments.
