What Amadeus Capital Partners does

Amadeus Capital Partners is a UK-based deep technology venture capital firm founded in 1997 by Anne Glover and Hermann Hauser. The firm invests from seed to growth stages in technology companies operating across three thematic areas: Intelligence (AI, machine learning, advanced computing, quantum), Human (health, medicine, wellness), and Planet (sustainability, energy, novel materials, space utilisation). It has backed more than 200 companies, recorded 17 IPOs, and raised over $1.3 billion cumulatively across six fund vehicles, with offices in London (headquarters), Cambridge and Oxford.

The firm's product surface consists of fund vehicles rather than software products. The flagship is the early-stage Amadeus fund series (Funds I-V, the most recent being Amadeus V at £110m in 2018), complemented by the Amadeus APEX Technology Fund (€80m, partnership with APEX Ventures, 2023) targeting European deep tech and the Amadeus Royal Society Enterprise Fund backing Royal Society research spinouts. Supporting offerings include the Capitalise newsletter, the In Focus podcast, and the Trailblazers Community for portfolio founders. Notable portfolio companies span Photonic Inc. (quantum, ~$300m raised), Nu Quantum (quantum networking, $60m Series A), Pimloc (AI video privacy), Altana AI (supply chain federated learning), XMOS (semiconductors), and Slamcore (visual AI for robotics). Marquee exits include OrganOx (acquired by Terumo for $1.5bn in 2025), Element 14 (Broadcom, $642m in 2000), Icera (NVIDIA, $430m in 2011), and VocalIQ (Apple, 2014).

The business model follows the standard venture capital structure: Amadeus charges Limited Partners a management fee (industry-standard ~2% on committed capital during the investment period, stepping down thereafter) and earns carried interest (typically ~20%) on profits from successful portfolio exits. The firm is authorised and regulated by the UK Financial Conduct Authority and operates as Amadeus Capital Partners Limited. Revenue is therefore a function of committed AUM, fund vintage mix, and the timing of realisation events, with carried interest providing material but lumpy upside on exits such as the 2025 OrganOx sale.

Core offering

Amadeus Capital Partners is a UK-based deep technology venture capital firm that provides equity capital, strategic guidance, and operational support to early- and growth-stage technology companies. It invests from seed to growth across three themes—Intelligence (AI, computing, quantum), Human (health, medicine, wellness), and Planet (sustainability, energy, novel materials, space)—through its flagship Early Stage Fund series, the €80m Amadeus APEX Technology Fund (with APEX Ventures), and the Amadeus Royal Society Enterprise Fund.

Product overview

Amadeus Capital Partners is a deep tech venture capital firm founded in 1997, operating as a single unified investment platform rather than a product company. It has backed more than 200 companies and raised over $1.3 billion for investment. The firm invests from seed to growth across three technology areas — Intelligence (AI, advanced computing, and quantum), Human (health, medicine, and wellness), and Planet (sustainability, energy, novel materials, and space utilisation) — delivering funding, strategic support, and portfolio company resources to founders. Notable sub-brands include the Amadeus APEX Technology Fund (€80m European deep tech partnership with APEX Ventures) and the Amadeus Royal Society Enterprise Fund. The firm also publishes the Capitalise newsletter and hosts the Trailblazers Community for portfolio founders. While Amadeus itself is not a product company with integrations, certifications, or APIs, its portfolio companies — including Slamcore (visual AI), Refute (counter-disinformation AI), Tenzo (hospitality analytics), Nu Quantum (quantum networking), and Pimloc (video privacy) — develop products with their own respective AI capabilities, integrations, and certifications.

Direct peers

• LocalGlobe: UK seed-stage venture firm backing mission-driven tech founders. Comparable as a London-based early-stage investor in deep tech and frontier software, often co-investing in UK rounds.
• IQ Capital: Cambridge-based deep tech VC investing across AI, quantum, and advanced engineering. Most directly comparable peer given co-investment history with Amadeus (Nu Quantum rounds) and an identical Cambridge/London origination footprint.
• Lux Capital: US deep tech and science VC investing in AI, quantum, biotech, and space. Comparable thematic overlap (Intelligence/Human/Planet-style coverage) and a similar contrarian frontier-tech posture.
• DCVC: US deep tech VC focused on AI, materials, and life sciences. Comparable as a sector-focused deep tech specialist, though larger in AUM and US-headquartered; useful benchmark for check-size and exit scale.
• Octopus Ventures: UK-based VC with a deep tech and healthtech focus. Comparable UK footprint and early-stage orientation, with overlapping portfolio themes in AI and biotech.
• Earlybird: European deep tech and tech VC with active seed-to-growth investing in AI, quantum, and healthtech. Comparable as a long-standing European specialist operating across similar verticals and stages.

Broad incumbents

• Balderton Capital: London-based early-stage tech VC. Comparable UK footprint and early-stage orientation, though broader sector coverage and larger typical Series A check sizes.
• Atomico: European tech VC with broader stage and sector coverage than Amadeus. Comparable as a Europe-anchored thesis-driven VC but with a wider mandate spanning consumer and enterprise software.
• Index Ventures: Global tech VC with strong European roots. Comparable as a long-standing Europe-headquartered VC, but with a broader sector mandate and significantly larger fund sizes.

Regional players

• Speedinvest: European sector-focused early-stage VC covering fintech, deep tech, and industrial tech. Comparable as a sector-specialist early-stage firm, though primarily Continental European rather than UK-focused.
