10 Swedish Tech Startups to Watch in 2026

1. Lovable

Lovable is a Stockholm-based AI software creation company that allows people to build production-ready websites and applications through natural-language conversations with AI, dramatically lowering the technical barrier to software development.

Founded in 2023 by Anton Osika and Fabian Hedin, the company grew out of Osika’s open-source GPT Engineer project and publicly launched Lovable in November 2024. Osika serves as CEO and Hedin as CTO, with the pair building a platform aimed at the large population of people who have ideas for software but lack traditional programming skills.

In August 2026, Lovable announced a $400 million Series C at a $13.3 billion valuation, led by Menlo Ventures and co-led by EQT’s Scaleup Europe Fund. New investors included Balderton Capital, Carmignac, Kaszek Ventures, LTS Growth, Tencent, World Innovation Lab and Regent, while existing backers including Accel, Antler, CapitalG, DST Global, Evantic Capital, HubSpot Ventures and Salesforce Ventures also participated.

The new financing came after a $330 million Series B in December 2025 and a $200 million Series A in July 2025. Lovable says users have created more than 60 million projects, while applications built on the platform receive more than 900 million visits every month.

The company is now expanding its ambitions beyond helping people create software toward helping them operate businesses built with it, adding payments, SEO, integrations, security and governance capabilities. It plans to grow to approximately 450 employees while maintaining Stockholm as its center of gravity and expanding teams in London, Boston, San Francisco and New York.

2. Aira

Aira is a Stockholm-founded clean energy technology company focused on electrifying residential heating across Europe through intelligent heat pumps and an integrated customer proposition. Founded by Vargas in 2022, Aira is built around the idea that replacing gas boilers with electric heat pumps can significantly reduce household emissions and energy costs while helping Europe transition away from fossil-fuel heating.

The company operates a vertically integrated model covering product development, manufacturing, installation and customer financing, allowing households to access its systems through monthly payment plans rather than necessarily paying the full upfront cost. Aira’s leadership includes Group CEO Peter Prem, while its Swedish research and development operations support the company’s technology and product portfolio. Since launching commercially in June 2023, Aira has expanded into Germany, Italy and the UK, building a European network of hubs and installer-training academies.

In August 2025, the company announced €150 million in additional equity financing from existing investors Altor, Kallskär, Kinnevik, Lingotto and Temasek. At the time, Aira reported an annual sales run-rate of €200 million, around 1,200 employees, 18 hubs and four Aira Academies across Europe. The funding is being used to accelerate expansion, increase production capacity at its Polish factory, strengthen operations in existing markets and invest further in its Swedish R&D center.

Aira’s opportunity is closely tied to Europe’s enormous residential heating market, where the company estimates that around 130 million boilers remain in use and heating represents a significant source of emissions. With heat-pump adoption expected to accelerate as governments, consumers and energy companies pursue electrification, Aira is attempting to build a large European consumer brand around the transition from fossil-fuel heating to cleaner home energy.

3. Tandem Health

Tandem Health is a Stockholm-based healthcare technology company developing an AI medical assistant designed to reduce the administrative burden placed on clinicians. Founded in 2023 by Lukas Saari, Oliver Åstrand and Oscar Boldt-Christmas, Tandem built its initial product around ambient clinical documentation, allowing physicians and other healthcare professionals to have natural conversations with patients while the system listens and generates structured medical notes.

The company has since expanded its vision toward an AI-native operating system for clinical workflows, with the broader objective of automating administrative tasks while allowing clinicians to spend more time with patients. Tandem’s growth has been supported by substantial venture funding.

In June 2025, the company announced a $50 million Series A led by Kinnevik, with Northzone, Amino Collective and Visionaries Club also participating. Kinnevik subsequently appointed its chair Cristina Stenbeck to Tandem’s board, highlighting the strategic importance investors place on the company’s European healthcare opportunity. Tandem says more than 1,000 healthcare organizations across Europe use its technology and that clinicians can save up to two hours of documentation time per day. Its active markets include Sweden, Norway, Denmark, Finland, the UK, Germany, France, Spain, the Netherlands, Italy and Estonia.

The company’s opportunity extends beyond transcription because healthcare providers generate vast amounts of information during consultations, much of which traditionally requires manual processing afterward. By turning spoken interactions into structured clinical data and increasingly automating related workflows, Tandem is positioning itself within the broader transformation of European healthcare administration through AI.

4. Endra

Endra is a Stockholm-based AI company building software that automates mechanical, electrical and plumbing engineering for commercial buildings. Founded in 2024 by Niklas Lindgren, Anton Juric, Gustav Hammarlund and David Rydberg, the company emerged from the founders’ experience with engineering and security businesses and their exposure to the highly manual workflows used in MEP design.

Its platform ingests building information models, reconstructs buildings in three dimensions and applies engineering rules to automate tasks that historically require extensive manual work. The company’s initial focus is electrical engineering, with the broader ambition of creating an AI-native platform for the built environment.

Endra has experienced exceptionally rapid funding momentum. After raising a $20 million seed round led by Notion Capital in December 2025, the company announced a $50 million Series A led by Andreessen Horowitz in June 2026, with Notion Capital and Norrsken also participating. The Series A was announced less than six months after the seed round and brought reported total funding to approximately $73.4 million.

Investors say Endra’s opportunity sits within a global MEP engineering services market worth more than $150 billion and that the company’s technology can reduce design tasks that previously consumed weeks or months to dramatically shorter workflows. Endra has attracted a waiting list of hundreds of companies across more than 90 countries and has been expanding into the United States, continental Europe and the Middle East.

Its progress is significant because construction remains one of the world’s largest industries with relatively slow-moving software infrastructure. If Endra can successfully automate increasingly complex engineering processes while maintaining the precision required by building codes and professional standards, it could become an important software layer for the global built environment.

5. Bits

Bits is a Stockholm-based fintech infrastructure company helping regulated financial businesses automate anti-money-laundering, know-your-business, know-your-customer and broader financial-crime compliance workflows. Founded in 2022 by Jonatan Klintberg, Robin Lantz and Fredrik Eriksson, the company was created after its founders saw firsthand how fragmented compliance and infrastructure processes could slow down fintech businesses. 

Klintberg serves as CEO, Lantz as CPO and Eriksson as CCO, with the founders bringing experience from companies including Tink, Klarna, AWS and Apple. Bits’ platform connects financial companies with data sources and compliance tools, helping them manage customer onboarding, risk assessment, screening, transaction monitoring, ongoing due diligence and case management through a more unified infrastructure layer.

The company initially raised €1 million in pre-seed funding from Cherry Ventures and later secured a €4 million seed round from Unusual Ventures and Fin Capital. In February 2026, Bits announced a €12 million Series A led by Alstin Capital, with participation from Cherry Ventures, Unusual Ventures and Alliance Ventures. The company said the funding would accelerate product development and European expansion, increase automation across financial-crime workflows and expand its coverage of regulatory and data sources.

Its market opportunity is being driven by the increasing complexity of financial regulation and the growing cost of fraud and money laundering for banks and fintech companies.

Rather than building another consumer-facing financial product, Bits is developing the infrastructure behind regulated financial services. As fintech expands across Europe and regulatory requirements become increasingly sophisticated, technology capable of making compliance faster, more scalable and easier to manage could become an important competitive advantage.

6. Lightbringer

Lightbringer is a Malmö-based legal technology company developing an AI-powered patent platform designed to help startups and deep-tech companies build, manage and protect intellectual property. Founded in 2023 by Dominic Davies, Markus Andreasson and Ola Wassvik, the company combines AI software with human patent-attorney expertise.

Davies serves as CEO, Andreasson as CTO and Wassvik as CCO. Their combined backgrounds give Lightbringer unusual experience across both technology and intellectual property: Davies spent two decades as a patent attorney after beginning his career as a software engineer, Andreasson has more than 25 years of software-development experience and more than 50 patent applications, while Wassvik previously co-founded and served as CTO of FlatFrog, where he managed more than 300 patent families and helped raise close to $100 million.

Lightbringer’s platform supports activities ranging from identifying inventions and developing patent strategies to analyzing existing patents and managing applications, with attorney oversight built into the process. The company raised €4.2 million in 2024 from Luminar Ventures and Alliance VC, with additional participation from Zenith Ventures and angel investors. In June 2026, Lightbringer announced a $10 million Series A co-led by 6 Degrees Capital and Newion, with existing investors Luminar Ventures and Alliance VC participating. The company said the capital would support further platform development and expansion into the United States.

Lightbringer has worked with more than 200 deep-tech companies across 17 countries and reported 300% year-over-year revenue growth in the second quarter of 2026. By combining AI with specialist legal expertise, Lightbringer is targeting an area where speed and technical understanding can directly affect the ability of young technology companies to protect their innovations.

7. Oplane

Oplane is a Malmö-based cybersecurity startup building an AI-native security platform for software teams developing applications at increasingly rapid speeds with AI coding tools. Founded by Emil Kvarnhammar, Oscar Andersson and Anders Söderling, the company focuses on architectural security and automated threat modeling rather than simply scanning individual lines of code for known vulnerabilities.

Kvarnhammar serves as CEO, Andersson as CTO and Söderling as CPO, with the founding team bringing extensive cybersecurity, software and entrepreneurial experience. Kvarnhammar previously spent more than 15 years working in cybersecurity and threat modeling and helped grow TrueSec from 16 to more than 100 employees; Andersson has more than 15 years of cybersecurity-development experience, while Söderling was a technology co-founder of Position Green.

Oplane’s central argument is that AI-assisted development is allowing software to be created faster than traditional security processes can evaluate it. Its platform therefore runs continuously alongside development, identifying architectural risks and helping engineering teams understand threats involving AI-generated code, agents and technologies such as Model Context Protocol servers.

In June 2026, Oplane raised €4.5 million in seed funding led by Seed Capital, with participation from Icebreaker.vc and angel investors including Neo4j co-founder Emil Eifrem, Robert Lagerström and Joakim Nydrén. The company’s opportunity is tied directly to the rise of AI-assisted software development. As coding agents enable smaller teams to ship more software at much greater speed, security teams face the challenge of reviewing systems whose architecture can change continuously.

Oplane is attempting to make security an integrated part of that new development process rather than a separate review conducted after software has already been built.

8. Redpine

Redpine is a Stockholm-based AI data platform focused on giving AI builders and autonomous agents access to high-quality, licensed and non-public data. Founded in 2024 by Anders Hammarbäck and David Österdahl, the company argues that the next bottleneck for advanced AI is not simply model capability but access to trustworthy data outside the open web. 

Hammarbäck serves as CEO and co-founder, while Österdahl is CTPO and brings previous experience from Spotify, Zettle and Lunar. The team also includes founding data scientist Dr. Leonora Vesterbacka, who has experience from CERN and AI research. Redpine’s platform provides licensed datasets through APIs, Model Context Protocol and command-line access, allowing AI applications and agents to consume proprietary information in structured, compliant formats.

The company specifically emphasizes that it does not rely on web scraping and instead works with content and data partners through licensing agreements that establish provenance and AI rights. Its business model combines usage-based access for AI builders with revenue sharing for data owners. Redpine emerged from stealth with backing from investors and technology figures associated with companies including OpenAI, Spotify, Perplexity and Xiaomi.

In April 2026, it raised $8 million in seed funding led by NordicNinja, with participation from Luminar Ventures and node.vc. The company said the capital would accelerate global expansion, strengthen its retrieval and reranking technology and expand its network of proprietary data partnerships.

As AI systems increasingly move toward autonomous agents that need reliable information in areas such as finance, healthcare, law and robotics, Redpine is targeting a potentially critical infrastructure layer: making valuable non-public knowledge accessible to machines without sacrificing quality, provenance or compensation for its owners.

9. DREV

DREV is a Gothenburg-based industrial technology company developing contamination-control equipment for advanced manufacturing environments, with a particular focus on battery production and recycling. Founded in 2023 by Arelys Sosa and Thomas Tingelöf, DREV is addressing an overlooked challenge in modern manufacturing: managing the fine particles and “black dust” generated during battery production.

Sosa serves as CEO and Tingelöf as CTO and COO, while the team brings experience from companies including Panasonic Energy of North America and PowerCell.

DREV’s flagship Vault technology uses patent-pending dry-brush technology and sealed collection systems to remove contamination without relying on water or harsh chemicals. Its mobile, stationary and autonomous systems are designed to clean factory floors, walls, ceilings and hard-to-reach areas while capturing valuable particles that can potentially be recovered and reused. The company says the technology can reduce worker exposure, prevent cross-contamination and help recover materials such as lithium, nickel, cobalt and copper from battery manufacturing and recycling environments.

In November 2025, DREV raised €2.8 million in seed funding co-led by Butterfly Ventures and Almi Invest GreenTech, with participation from S-E-Bankens Utvecklingsstiftelse and Battle Born Venture. The funding is supporting product development, commercial deployment and Swedish manufacturing operations.

DREV’s proposition becomes particularly relevant as global battery manufacturing capacity expands and factories become larger, more automated and more sensitive to contamination. The company’s approach links workplace safety, production efficiency and material recovery, turning what has traditionally been treated as a cleaning expense into a potential source of operational and environmental value.

10. Digiclean Solutions

Digiclean Solutions is a Swedish industrial deep-tech company developing technology that gives manufacturers real-time visibility and control over the chemistry used in industrial cleaning and washing processes. Founded in 2024 by Charlotte Stigen Låstberg, the company emerged from her experience in the industrial chemicals sector and a recognition that process-fluid management remained heavily dependent on manual sampling despite the wider digitization of manufacturing. Låstberg serves as CEO and founder, with the team also including COO Henrik Nel Jerkrot and CTO Adrian Welter.

Digiclean combines IoT sensors, data analysis and AI models to continuously monitor cleaning baths and automatically adjust chemical dosing, replacing manual sampling with real-time information and more precise control. The company says its technology can reduce chemical consumption by as much as 69% and wastewater by 94%, while its customers include industrial manufacturers such as Volvo, SKF and Parker Hannifin. Its platform has already been deployed at more than 20 industrial sites in Sweden.

Digiclean reached an important financing milestone in June 2026 when it raised €2.5 million in seed funding, with investors including Unconventional Ventures, Almi Invest GreenTech, Feminvest Ventures, Impact Shakers and S-E-Bankens Utvecklingsstiftelse. The capital is being used to accelerate product development and expansion across European industrial markets. 

The opportunity lies in applying industrial intelligence to a process that has historically received relatively little digital attention. By optimizing the amount of chemicals, water and energy required to keep manufacturing components clean, Digiclean is seeking to demonstrate that sustainability improvements can also translate into better process control, lower operating costs and reduced waste.

Sweden’s Technology Ecosystem Keeps Expanding Its Reach

The ten startups featured here reflect a Swedish technology ecosystem that is increasingly comfortable operating across both software and the physical world. AI is clearly a major theme, from Lovable’s software creation platform and Redpine’s data infrastructure to Tandem Health’s clinical assistant and Oplane’s AI-native cybersecurity approach.

But Sweden’s emerging technology companies are also addressing tangible challenges in heating, industrial manufacturing, batteries and the built environment. The funding environment reinforces that momentum: Swedish startups raised €2.8 billion across 83 rounds in the first half of 2026, up 68% year over year, while software remained the country’s most active sector. 

Several companies in this list have also demonstrated the ability to attract international capital and expand beyond Sweden, showing how the country’s relatively small domestic market can serve as a launchpad for globally oriented businesses. Lovable’s $13.3 billion valuation, Endra’s rapid progression to a $50 million Series A, Bits’ European compliance ambitions and Aira’s expansion across major European markets illustrate different versions of the same broader trend.

Sweden’s startup story in 2026 is therefore not confined to one technology or one industry. It is increasingly about combining strong engineering, ambitious product development and global market thinking to create companies capable of competing far beyond the country’s borders.
