Mega and Late-Stage Raises
Two headline-grabbing rounds set the tone for the day, both in AI.
- Domyn, an AI model maker, raised over $1B in a round that signals continued investor appetite for foundational model infrastructure. Lead investor details were not disclosed at time of reporting.
- Fractile, a UK chip startup, is in talks to raise at a $6.5B valuation, according to reports. No round size or lead investor has been confirmed yet.
These raises underscore how capital continues to concentrate at the top of the AI stack, where the competition to control model and chip infrastructure is fiercest.
Large Seed and Series A Rounds
Below the billion-dollar tier, several substantial rounds closed across AI, life sciences, and commerce.
- Callosum (London), building software infrastructure to unify AI models and chips across heterogeneous hardware, raised $100M in a Seed round led by Atomico, with participation from Plural, DCVC, and the UK Sovereign AI Fund.
- Pixelgen Technologies (Stockholm), which has built a high-throughput platform for spatial mapping of cell-surface proteins, closed an oversubscribed $15M Series B led by Flat Capital, with continued backing from Industrifonden and Navigare Ventures.
- Peeko (Bengaluru), a quick-commerce babycare platform, raised approximately $8M (Rs 67.4 Cr) in a Series A led by Chiratae Ventures, earmarked for expansion, technology, and hiring.
Seed and Pre-Seed Activity
Early-stage deal flow was active across Europe, with several sectors represented.
- Velatir (Odense, Denmark), an AI infrastructure platform, secured $6M (EUR 5M) in a Seed round co-led by Spintop Ventures and existing investor Ugly Duck, just six months after its official launch.
- Solinide Photonics (Sweden), developing silicon-nitride photonic integrated circuits for AI data centres, raised $5M (EUR 4M) in seed funding to prepare for scalable manufacturing.
- Guideless (Vilnius), an AI platform that converts software workflows into narrated video training guides, raised $1M (EUR 1M) in a pre-Seed round led by Superhero Capital, with participation from FIRSTPICK VC and angel investors including Vinted CEO Thomas Plantenga.
- Artwod (Antwerp), a guided learning and community platform for visual artists, raised $1.2M (EUR 1.1M) in a Seed round with participation from Airbridge Equity Partners and ForsVC, to launch a creators' marketplace.
- Paralo (UK), building an operating system for golf clubs, raised approximately $340K (GBP 270K) in an oversubscribed pre-seed round, with GBP 250K from a lead source not fully detailed at time of reporting.
Accelerators and Programme Funding
- MC2 Foundation launched an accelerator for energy deeptech startups in India, offering up to Rs 2 crore in milestone-linked convertible funding to approximately 30 selected startups, along with access to pilot sites, labs, and industry partners.
Editorial Perspective
The day's raises tell a fairly coherent story. Capital is clustering around two themes: the physical layer of AI compute (chips, photonics, hardware-software unification) and the application layer that sits directly on top of it (model infrastructure, AI training tools, AI-native fintech). The extraordinary size of Callosum's seed round, at $100M, reflects a broader pattern in which investors are writing growth-stage cheques at the earliest company stages when the perceived infrastructure opportunity is large enough. Meanwhile, the presence of the UK Sovereign AI Fund in Callosum's round is a reminder that governments are no longer passive observers of this build-out. The life sciences and consumer rounds rounding out the day suggest that deal flow outside AI remains healthy, even if it commands far less attention.
