At Scale CFO Services, we’re always on the lookout for high-potential startups pushing the boundaries of innovation. This month’s top five companies are making waves with cutting-edge technology. Here’s why you should keep them on your radar:
Medical device for affordable hair loss treatment
Founded in 2022 in Barcelona, Hair Up Laser has developed a medical device for the treatment of hair loss. Over 190 million people worldwide suffer from hair loss causing anxiety in a third of all cases with only limited and expensive existing treatment options. Hair up Laser has developed a proprietary technology that was clinically proven to regenerate hair follicles in a pilot study performed in 2024.
Why we are excited about them: In December 2024, the company received a EUR 250.000 grant from the Spanish Government under the CDTI Neotec-program to validate their technology. In 2025 they are planning a clinical trial with up to 100 patients and adaptation of medical device reporting standards. They plan to enter the European market starting in Spain making their device accessible to users at home at the beginning of 2027.
Novel propulsion systems for small satellites
Ienai Space develops electric propulsion systems for the growing fleet of nano-satellites which will revolutionize access to space over the next 10 years. Combined with its mission analysis and design software which optimizes the use of the thrusters, the company’s ionic-liquid propulsion modules are highly efficient and require less propellant, allowing nano-satellites to stay in orbit for longer.
Why we are excited about them: In June 2024, Ienai Space raised EUR 3.900.000 in a round led by GED Conexo Ventures with participation from Inveready, WA4STEAM, DPM and CDTI to accelerate commercialization and to open new facilities. In April 2025, the company was awarded an additional EUR 2.300.000 by the Spanish Space Agency to lead the ATALAIA project focusing on the industrialization of its propulsion system for small satellites.
Improving road safety with artificial intelligence
Founded in 2023 in Italy, LOKI collects road images and data using plug & play hardware installable on a vehicle and operating at speeds of up to 90 km/h. The systems leverage AI and advanced sensors to detect and classify road defects, road signage and accessibility to pedestrian crossings, enabling road managers to plan maintenance, prevent accidents and increase pedestrian safety in urban areas.
Why we are excited about them: In November 2024, LOKI successfully piloted a project in Las Rozas, Madrid, which is part of the EIT Urban Mobility initiative, using their system to scan over 400 pedestrian crossings and to identify issues like poor signage, uneven surfaces or missing ramps. This initiative highlighted the potential of AI-driven solutions in empowering cities to plan for long-term infrastructure improvements.
Improving performance of 3D-printed parts
Founded in 2022, Reinforce3D focuses on commercializing the Continuous Fiber Injection Process technology which drastically improves the mechanical and light-weighting performance of 3D-printed parts by reinforcing them with continuous carbon fibers. The technology can be used with any existing material and allows the efficient manufacturing of large, multi-material and multi-process structures.
Why we are excited about them: In March 2025, Reinforce3D received EUR 1.200.000 in seed funding in a round led by BeAble Capital with participation from Fundació Eurecat and Institut Català de Finances. The injection of funds will enable the company to expand its capabilities for larger scale production, strengthen its R&D team and consolidate its presence in strategic markets such as automotive, aerospace and sports.
Detecting nanoscale defects in Semiconductor wafers
Founded in 2014, Wooptix develops optical metrology systems used in the production of semiconductors to measure silicon wafer warpage. Using proprietary technology, these systems enable measurements with higher resolution than current solutions. They have already been adopted by several manufacturers and are on track for factory-floor deployment for in-line testing in the coming months.
Why we are excited about them: In February 2025, Wooptix secured EUR 10.000.000 in Series C funding in a round led by Samsung Venture Investment Corporation and Spanish Society for Technological Transformation with participation from existing investors. The company plans to use these funds to accelerate product development, expand international reach and to scale their team to meet growing demand.
These startups exemplify the innovation and ambition driving the high-tech ecosystem in Spain. Stay tuned as they continue to reshape their industries and push the limits of what’s possible.
