- Qureight
Participated · Series B · Jul 2026
Qureight provides two integrated products for pharmaceutical clinical trials: Workflow, which speeds imaging decision turnaround from about two weeks to 48 hours, and AI Lung, which constructs detailed models of airways and blood vessels from chest scans. The company has built a general-purpose foundation model of the chest that enables development of disease-specific deep learning models in one to two months. Qureight is running global clinical trials with partners including AstraZeneca, Bristol Myers Squibb, and several biotech firms. Founded in 2018, the company combines clinical leadership—co-founder and CEO Dr Muhunthan Thillai continues clinical work—with a senior technical team recruited from industry and academia. Financially, Qureight has raised a £1.5 million seed in 2022 and the recent $20 million Series B to support lab build-out, therapeutic-area expansion, and headcount growth.
- Valarian Technologies
Participated · Series A · Jul 2026
Valarian Technologies develops ACRA, a software layer described as a sealed operating room for AI workloads and sensitive applications that controls what data leaves systems, who can access it, and who can shut it off. The product is positioned to let governments and enterprises retain control while still using major cloud providers by enforcing policy and access controls outside those providers’ native stack. The company was founded and is led by Max Buchan, with co-founder Josh McLaughlin joining from a senior role at Palantir, and is based in London. Valarian’s positioning responds to geopolitical risks such as the U.S. CLOUD Act and recent restrictions on access to U.S.-based AI services. Financially, the company has raised $70 million to date, including a $50 million Series A led by NEA.
- Proxima Fusion
Led · Series A · Jul 2026
Proxima Fusion is Europe’s leading stellarator company and the first spin-out from the Max Planck Institute for Plasma Physics, developing commercial fusion power plants using the QI-HTS stellarator concept. The company is building Alpha, a net-energy stellarator demonstrator targeted for the early 2030s, and plans a follow-on commercial plant called Stellaris later in the decade. Proxima leads the Alpha project in partnership with the state of Bavaria, the Max Planck Institute for Plasma Physics and industrial partners including RWE, supported by an Alpha Alliance of more than 50 companies. Headquartered in Munich with offices in Zurich and Oxford, Proxima employs around 200 people across engineering, science and operations. Financially, Proxima has secured more than €650 million in funding to date, including about €95 million in public grants, and plans to expand engineering, manufacturing and magnet production capabilities as it advances toward demonstrator completion.
- Kopa.ai
Led · Seed · May 2026
Kopa.ai is developing an operating-system-like platform that lets e-commerce teams delegate operational and analytical work to AI agents that understand context, make decisions, and execute tasks. The platform connects directly to merchants’ existing tools and storefronts to continuously analyze products, campaigns, inventory, customer behavior and site performance. Its agents can identify opportunities, generate creatives, adjust campaigns and reallocate budgets, running actions with human approval or autonomously based on customer preferences. Kopa.ai emphasizes interpreting intent rather than relying on prompts or predefined workflows, with every action and outcome feeding back to improve judgment and execution over time. Under the hood the company is building proprietary systems for structuring business knowledge, managing operational context and orchestrating specialized agents at scale. The team behind Kopa.ai brings more than a decade of hands-on e-commerce experience to the product and go-to-market strategy.
- Ethos Recruits
Participated · Series A · May 2026
Ethos uses AI to map users' comparative advantages and match them to paid opportunities across the economy, including expert calls, research, AI training, fractional roles, and full-time jobs. The company reports rapid user growth, with about 35,000 people joining the platform each week. Ethos also highlighted that some people on the platform are earning up to $10,000 per month. The product messaging emphasizes augmenting workers' judgment and instincts rather than replacing them with AI. Public communications about the company and its metrics have been made by its leadership in tandem with fundraising announcements. No revenue, valuation, or founding-year details were disclosed in the provided announcement.
