  • Eyedentity

    Led · Seed · Aug 2026

    Eyedentity, founded in 2025 and based in Stockholm, is developing an AI diagnostics platform that analyses fundus images taken during routine eye exams to detect serious eye diseases. Its first clinical application targets uveal melanoma, a rare but potentially deadly intraocular cancer, and the company says its system can reduce false-positive referrals by 90%. Eyedentity is running a live pilot with Synologen, a network of independent opticians in Sweden, and aims to integrate with medical record systems to minimise workflow friction for opticians. The founders combine clinical and technical expertise, including an ocular oncologist from St. Erik Eye Hospital and a machine learning engineer with prior experience at RaySearch Laboratories. The company plans to expand its platform to other eye diseases such as diabetic retinopathy and glaucoma and pursue commercialisation in the Nordics before scaling across Europe and the US.

  • Callosum

    Participated · Seed · Aug 2026

    Callosum’s platform sits between applications and hardware, decomposing AI inference workloads, matching sub-tasks to specialised models and processors, and routing execution to the most suitable hardware to balance speed, cost and precision. The company claims up to 4x speed improvements, 70% lower compute costs and a 10% higher task success rate on complex agentic financial workloads compared with running a single frontier model on conventional GPUs. A family of tailored inference APIs is being launched, with some APIs already in production for complex workloads in financial services. Callosum works with a range of silicon and infrastructure partners — including Cerebras, Rebellions, Axelera, Tendrils and Supermicro — and is a founding member of ARIA’s Scaling Inference Lab. The startup was founded by Danyal Akarca and Jascha Achterberg, who met while doing PhDs at Cambridge, and plans to use the new funding to scale the technology, deepen ecosystem partnerships and grow the team.

  • Verse

    Participated · Series B · Jun 2026

    Verse develops an energy infrastructure platform called Aria that centralizes utility bills, contracts and power purchase agreements across sites. Aria gives customers a unified view of energy data so they can compare forecasts to actual performance, make procurement decisions, optimize portfolio performance, and reduce costs and risk. Verse also offers Dispatch Intelligence, which extends its capabilities from energy management to power access and delivery. The platform is already used by Fortune 500 companies. The company is led by CEO Seyed H. Madaeni and CCO Matt Penfold and is based in San Francisco. In June 2026 Verse completed a $54M Series B to support further product development and deployment.

  • Endra

    Participated · Series A · Jun 2026

    Endra develops an infrastructure and purpose-built platform for mechanical, electrical, and plumbing (MEP) engineering firms that incorporates Spatial AI, optimization, simulation, and physics-based physics modeling. The company positions its technology as intended for engineers who design systems for data centers, hospitals and office buildings. It is preparing to launch an electrical module at its Endra Epoch event on September 14 in Las Vegas. Endra is expanding its team and hiring across offices in Stockholm, London, New York and San Francisco. Financially, the company has raised $74 million over the past 12 months, including a $50 million Series A led by Andreessen Horowitz.

  • Renasens

    Participated · Seed · Mar 2026

    Renasens has developed a platform that uses modified supercritical CO₂ to separate and decolour blended textiles and recover intact fibres without water or toxic chemicals. The recovered materials can be reintroduced into existing manufacturing processes without requiring new equipment, and the system is designed to be modular for deployment within existing facilities. The company says its technology enables fibre‑to‑fibre recycling at industrial scale and aims to reduce reliance on imported virgin materials. Renasens has already begun supplying recovered cotton and polyester fibres to manufacturers in Portugal and Italy. The new funding will be used to build and develop a pilot plant in Borås, Sweden, and to scale supply of recovered fibres into European manufacturing. The company positions itself to address the large volume of post‑consumer textile waste in Europe and to respond to tightening EU recycling regulations.
