Switzerland's top-funded tech companies in H1 2026

Swiss tech companies pulled in more than €1.1 billion in the first half of 2026, and the money was not spread evenly. The ten biggest rounds made up about two-thirds of the total, which tells you plenty about where the momentum was — and where it wasn’t.

Series A was a major magnet for capital, helped by a handful of large deals. Seed and pre-seed, by contrast, were busier but smaller, with activity spread across more companies. Later-stage money also played a clear role, especially in Series C and Series E, while grants, growth equity, debt, convertible financing and equity crowdfunding were present but much smaller parts of the mix.

The sector split was even more telling. Semiconductors led with around €281 million, followed by energy at €223 million and healthtech at €220 million. Cleantech also drew serious funding, while fintech, software and other tech areas saw more deals, but generally at lower ticket sizes.

At the top of the company list sat Kandou AI, which raised $225 million to scale production of its AI connectivity chips and push deeper into hyperscale and AI infrastructure customers. Terralayr followed with €192 million for grid-scale battery storage in Germany and its LAYR flexibility platform. Then came CeQur with $100 million, SWISSto12 with €73 million, BLP Digital and Polares Medical with $50 million each, PAVE Space with $40 million, NUCLIDIUM with €28.6 million, Planetary with nearly €23 million, and Acutronic with $25 million.

The pattern is hard to miss. Switzerland’s funding market in H1 2026 was broad at the bottom and very concentrated at the top, with capital-heavy sectors doing the heavy lifting. That usually means the headlines belong to the big rounds, while everyone else has to fight for the scraps and the patience of investors.
