Top Deep-Tech Startups In Finland To Watch In 2027

Finland has become one of Europe’s most serious deep-tech markets.

Local startups raised €1.6 billion in 2025, a 170% jump on 2024, according to Tesi’s Deep Tech Study Finland, and global investors are still paying close attention.

That funding is heavily concentrated, though. More than €1.2 billion of the 2025 total went to just three names: Oura, IQM and ICEYE. So who’s coming up behind them?

Why Is Finland Such A Strong Deep-Tech Market?

Public support plays a major role, specifically targeting enterprises that require years of experimentation before generating turnover.

Business Finland’s Deep-Tech Accelerator targets young, research-heavy startups under five years old with funding spread across three phases totalling up to €400,000. By blending grants and loans to cover 75% of approved project costs, it forms just one of many crucial stepping stones for companies coming up behind the leaders.

Finnish startups raised roughly €1.3 billion across 53 deals in the first half of 2026, with deep-tech the most active sector.

The Top Deep-Tech Startups In Finland

Here’s a list of the top deep-tech startups in Finland, from space and quantum computing to energy and advanced materials.

ICEYE

ICEYE runs a commercial fleet of synthetic aperture radar satellites capable of imaging the Earth through thick cloud cover and total darkness. This capability makes the technology invaluable for defence, insurance, disaster response and environmental tracking. ICEYE claims the world’s largest synthetic aperture radar constellation and has already supplied sovereign satellite systems to seven European governments

A massive €450 million Series F primary round in June 2026 pushed its valuation past €10 billion under General Atlantic’s leadership. The main challenge for 2027 is turning that growth into steady recurring data revenue. To get there, ICEYE plans to scale production from 50 to 100 satellites a year by 2028.

Kuva Space

Kuva Space builds hyperspectral microsatellites that record the light wavelengths materials absorb, a kind of spectral fingerprint.

Founded in 2016 by Aalto University space technology students and based in Espoo, it sells analysed insights to users ranging from farmers to defence ministries. Its first commercial satellite launched in August 2024, and two are now in orbit.

The first two next-generation satellites, with four cameras and infrared capability, launching in 2026. Chief executive Jarkko Antila wants to image the entire planet daily by 2028, with 100 satellites by 2030, and the European Space Agency is a long-standing client.

IQM Quantum Computers

IQM develops full-stack superconducting quantum computers and offers cloud access to them, with customers across research, supercomputing and enterprise.

It has since listed on Nasdaq under the ticker IQMX and reported more than €102 million in orders in its first earnings release as a public company.

Pro forma cash stood at €309.4 million on 2 July 2026, following a €275 million Series B in 2025 and a €50 million financing in March 2026. The true test for 2027 rests on whether those order books translate into fully operational hardware.

Steady Energy

Steady Energy is engineering a 50 MW small modular reactor designed to generate heat instead of electricity, targeting municipal district heating grids.

The business emerged as a spin-out from the VTT Technical Research Centre of Finland in 2023, driven by chief executive Tommi Nyman’s observation that heating accounts for upwards of 40% of final energy consumption.

The European Investment Bank is investing up to €40 million through a convertible loan to fund development and licensing leading up to 2028. On 11 September 2026 the company signed a share exchange agreement with investment company 3North Partners, ahead of a planned Nasdaq First North listing, with about €69.8 million in subscription commitments.

Solar Foods

Solar Foods uses gas fermentation to make Solein, a protein-rich microbial powder grown from carbon dioxide, hydrogen and electricity, which it positions as a lower-emission alternative protein.

The product is currently on sale in Singapore and the United States. Its American debut arrived in May 2026 through an Ambrosia Collective protein powder, placing the company firmly among the top sustainability startups tackling food security.

Financing for the Factory 02 plant has reached €77.8 million, split between €39.6 million in grants and €38.1 million in R&D loans. The company aims to reach a final investment decision on the Lappeenranta site during 2026.

SemiQon

SemiQon manufactures silicon cryogenic microchips designed to manage quantum computers from inside ultra-low-temperature environments. Placed next to the qubits, these chips replace bulky bundles of room-temperature wiring. As a VTT spin-off, the firm utilises the Micronova cleanroom facilities in Espoo to build chips on equipment lines ready for mass production.

PostScriptum, founded by Silo AI co-founder Peter Sarlin, invested in SemiQon in July 2026 to support its expansion toward mass production. It follows a €17.5 million EIC-backed round in early 2025.

Dispelix

Dispelix is an Espoo-based company that designs the see-through displays inside augmented reality glasses.

By routing full-colour digital imagery through ultra-thin glass waveguides directly into the user’s view, the technology stays hidden inside lenses that mimic traditional eyewear. The company supplies both consumer and professional augmented reality devices, spanning near-eye panels and head-up displays, with active subsidiaries operating in the US and China.

Dispelix is fabless, meaning it designs the optics and works with nanophotonics foundries to manufacture them. It sells components instead of headsets, and raised a €28.4 million Series B in 2021, led by Atlantic Bridge. Its future depends on AR hardware actually taking off, and on winning design deals with headset and smart-glasses makers.

Canatu

Canatu is a spin-off from Aalto University’s Nanomaterials Group, founded in 2004, and makes carbon nanotubes using its own Dry Deposition process. The nanotubes are used to produce incredibly thin films and components for semiconductor manufacturing, automotive sensing and medical diagnostics. It also has operations in the US, Japan and Taiwan.

Few deep-tech companies in Finland have been around as long, and Canatu is now building a new factory and office of more than 3,000 square metres in Vantaa to support growth. The test is whether one material can scale across several demanding industries at once, each with its own long qualification cycles.
