Samos Investments Research
Investment Thesis
Samos Investments is a London-based venture capital and angel investment firm founded in 2008, focused on high-growth European businesses. The firm's own positioning is broad and generalist: it invests "across a range of sectors including deep-tech/AI, consumer internet, e-commerce, B2B Software, and financial services/technology." Unlike a narrow thesis-driven fund, Samos operates more like a syndicate of experienced private investors backing founders across the UK and wider Europe, frequently co-investing alongside larger institutional venture funds, family offices, and other private investors rather than acting as a sole thesis-first lead.
Sector Focus
The portfolio spans an unusually wide range of verticals for a firm of its size:
- Deep-tech / AI infrastructure (Callosum, WireScreen, Lighthearted AI, Intropic, Signal)
- Healthcare and biotech (Shennon Biotechnologies, Micrographia, Axiom Therapeutics, Kheiron Medical, Hesta Health, Level Zero Health, Jude, Kair, Vieve, Skin + Me, Doctify, Vitl, Urban Massage)
- Fintech and financial infrastructure (Curve, Moneybox, Round/Round Treasury, Credrails, BMLL, Small World)
- Consumer internet and e-commerce (Papier, Bloom & Wild, XOXO, Everpress, Lick, Urban Legend, Beautonomy, Ruka, Charlotte Tilbury)
- Enterprise software and martech (Ometria, Permutive, Metomic, Adzuna, Flair, Coniq)
- Deep-tech hardware and materials (Universal Quantum, Materials Nexus, Oxford Bioelectronics, Petagene, Geometry)
- Marketplaces, property and mobility (Spotahome, Second Home, Zoopla, Car Wow, Car Throttle, Zencargo)
- Crypto/web3 (Aztec Network)
- EdTech (Code First Girls)
Stage Focus
Samos describes its partners as "active angel/seed investors," and the portfolio shows a clear bias toward early-stage (seed and Series A) checks, with occasional follow-on participation into later rounds for standout portfolio companies (e.g., Signal AI's $165M round, Aztec's $100M round). No formal pre-seed/seed/Series A cutoffs are published on the firm's site.
Check Size
No specific check-size range is disclosed publicly. Given the angel/seed orientation and syndicate style of investing, checks are inferred to be modest relative to round size, typically as part of a syndicate alongside larger institutional co-investors (Octopus Ventures, a16z, OMERS Ventures, Battery Ventures, MMC Ventures have all appeared as co-investors across the portfolio).
Lead Tendency
Samos is described on its own site as taking "a proactive approach with its portfolio companies, working alongside many of the US and Europe's top venture funds, family offices and private investors" — language consistent with a syndicate/follow-on participant rather than a firm that typically leads institutional rounds. Lead tendency is therefore assessed as unknown/mixed rather than confidently "leads" or "follows."
Recent Activity
Samos remains an active investor into 2026. Recent portfolio activity includes Callosum's AI infrastructure seed round (widely covered from stealth-exit in February 2026 through an April 2026 Sovereign AI co-investment announcement), Electric Twin's $14M round (February 2026), Round Treasury's pre-seed and later funding, and continued momentum in the healthcare/biotech sub-portfolio (Shennon Biotechnologies, Level Zero Health). Third-party trackers (Pitchbook, Tracxn) list Samos as still actively deploying through mid-2026.
Portfolio Highlights
Notable exits and milestones include:
- BMLL — acquired by Nordic Capital in a $250M deal (October 2025)
- Charlotte Tilbury — sold a majority stake to Puig
- Nuji — acquired by Klarna
- Small World — sold in an £80M deal
- Moneybox — reached unicorn status (~$1.1B valuation per third-party trackers)
- Bloom & Wild — reached a ~$528M valuation
- Aztec Network — raised a $100M round led by a16z to build encrypted blockchains
The portfolio also includes several firms that are themselves investment vehicles or accelerators (Seedcamp, 1991 Ventures, Entrepreneurs First), suggesting some fund-of-funds or platform-style positions alongside direct operating-company investments.
