Stockholm Tech Raises $625M in 48 Hours as Venture Capital Defies European Lull
Three separate funding rounds-including a record $330M for AI-builder Lovable-underscore the capital’s position as Europe’s deepest startup pool outside Silicon Valley.
How we reported this
Stockholm’s technology sector has collected roughly $625 million in new venture capital over the past two days, a pace that reinforces the city’s reputation as the continent’s most capital-dense startup hub. The burst of funding arrived in three discrete transactions that span artificial intelligence, advanced nuclear engineering and early-stage portfolio investing.
Lovable lands $330M Series B
The headline number belongs to Lovable, a Stockholm-based AI web-app builder that secured $330 million in Series B financing. The round was co-led by CapitalG and Menlo Ventures, two large Silicon Valley firms that rarely make single-bet tickets of this size in Europe. Lovable has not disclosed a post-money valuation, but the amount is among the largest Series B rounds ever raised by a Swedish software company.
Blykalla closes $50M for next-gen reactors
On the hard-tech side, Blykalla, a nuclear-reactor developer headquartered in Stockholm, closed a $50 million investment led by Oklo together with existing backers Norrsken Launcher and Armada Investment. The company is developing lead-cooled small modular reactors, a technology that could supply zero-carbon baseload power to Sweden’s increasingly electrified industrial base. Blykalla has not announced a specific demonstration site, but its laboratory work is concentrated in the Royal Institute of Technology (KTH) district in northern Stockholm.
Propel Capital opens Fund VII for 40+ early-stage bets
Investor activity is not limited to mega-deals. Propel Capital has launched its seventh fund, Propel Capital VII, with a mandate to back at least 40 early-stage Stockholm startups between 2025 and 2027. The fund’s typical cheque size targets seed and Series A companies and it will draw on the same deal flow that has produced an unusually high density of unicorns in the city.
Stockholm now holds the highest unicorn density of any city outside Silicon Valley, according to data compiled by Swedish Tech News. Venture capital inflows reached $621 per capita-a figure that outpaces every other major European centre. The three deals announced this week alone exceed the full-year venture totals of many mid-sized European tech cities.
At least 14 major product launches and platform updates have been scheduled by Stockholm-based technology companies between now and the end of 2027, according to KTH’s innovation office. The pipeline includes software releases, hardware prototypes and commercial rollouts that could sustain the current pace of capital formation.
For now, the three funding rounds announced this week suggest that Stockholm’s early-stage ecosystem-supported by active investors like Propel Capital, Norrsken Launcher and Armada Investment-is converting research into companies that attract global capital. The question ahead is whether local infrastructure, including housing, energy supply and talent pipelines, can keep up with the rapid scale-up that the new funding implies.
