Top Startup Funding Rounds of September 24, 2026: Key Raises

A sprawling day of funding news saw defence tech, AI infrastructure, and climate access deals dominate headlines alongside a wave of European seed rounds.

Defence and Deep Tech Lead the Headline Numbers

The single largest raise of the day came from the defence sector, underlining how seriously institutional capital now takes dual-use autonomous systems.

  • TEKEVER, the Portuguese AI-powered autonomous systems maker, announced the first close of its $580M Series D at a $6.4B valuation, cementing its position as one of Europe's most valuable defence tech companies.
  • Basecamp Research, a UK life sciences startup applying AI to drug discovery, closed a $140M Series C backed by Anthropic and Nvidia, two investors whose involvement signals how central foundation-model partnerships have become to biotech funding.
  • StandardX raised £10M in seed funding to build an accelerator-based isotope refinery producing rare isotopes for medicine and nuclear fusion.

Growth and Series-Stage Rounds

Several companies at the growth stage secured meaningful capital to accelerate market expansion.

  • Ultraviolette, the Indian electric vehicle maker, raised $85M in a Series E led by deeptech fund Yali Capital, with US market entry targeted for 2027.
  • Brahma AI, an Indian AI platform focused on media, entertainment, and sports, raised $150M led by Multiples Alternate Asset Management.
  • Bird, the European business communications platform repositioning itself as an AI company, raised $450M in debt financing, though the round came alongside a headcount reduction from a peak of 1,000 employees to 120.
  • Magic AI secured £8M to bring its AI-powered fitness mirror to the US market.

Seed and Pre-Seed Activity

Early-stage deal flow remained strong across AI, fintech, and climate access.

  • 50skills raised $6M co-led by Frumtak Ventures and Swiss Post to scale its AI operating system for HR and people workflows.
  • mika, a Berlin-based vertical AI startup building an alternative to traditional tax firms for German SMEs, raised €6M in a seed round led by Smedvig Ventures.
  • Sun King received a $5M investment from Acumen to expand solar energy access in Zambia, addressing the country's electricity gap and reducing dependence on hydropower.
  • F13 emerged from stealth with $5M in pre-seed funding, led by Credo Ventures and Point Nine Capital, to build foundation models for vector graphics generation.
  • Spiich, a Stockholm-based AI sales agent startup, raised €3M led by Ugly Duckling Ventures.
  • Stasher, a London traveltech company operating a luggage storage marketplace, secured £3M to fund global expansion.
  • Crux Analytics raised €2M in seed funding to help financial institutions better engage and retain small business customers.
  • Palma.ai, an enterprise AI governance platform, raised $2M in pre-seed funding led by D11Z.

Ecosystem and Fund News

Beyond individual company raises, two structural developments caught attention.

  • Connect Ventures announced the first close of its $80M Fund V at $55M, anchored by British Business Bank, to back early-stage technical founders across Europe.
  • The European Commission and EIB jointly launched the European Institutional Investors Pact, a voluntary framework designed to channel more long-term institutional capital into Europe's scale-up ecosystem. Separately, Germany's SPRIND and the Netherlands' NADI launched a joint €40M challenge to accelerate European AI chip design.

What the Day's Raises Signal

The breadth of today's announcements reflects a funding environment that is simultaneously concentrating and diversifying. Defence tech and AI infrastructure are attracting the largest cheques, with TEKEVER and Basecamp Research both commanding nine-figure rounds backed by strategic investors. At the seed end, the volume of AI-native tools targeting SMEs, from tax accounting to HR workflows to sales automation, suggests founders see a clear near-term market in replacing professional services with software. The Sun King deal is a reminder that impact-oriented capital continues to flow into climate access plays in sub-Saharan Africa, even as the headline numbers remain modest relative to comparable rounds in Europe or India. Bird's $450M debt raise, paired with a dramatic headcount reduction, is the outlier worth watching: it suggests that restructured, leaner businesses can still access large pools of capital when the AI repositioning story is credible enough.
