QuantumLight Research

Investment Thesis

QuantumLight is a London-based quantitative venture capital and growth equity firm that describes itself as "an investment firm built as a technology company." Founded by Nik Storonsky, the founder and CEO of Revolut, and Ilya Kondrashov, a co-founder of European B2B payments company Kriya Finance, the firm's central bet is that technology can outperform traditional pattern-matching and network-driven sourcing in venture capital. QuantumLight built a proprietary AI system called Aleph, which analyzes over 10 billion data points across roughly 700,000 venture-backed companies since the 1990s to identify emerging outlier ('10x') companies before they become consensus deals. The team is explicitly composed of tech unicorn founders, quantitative traders, AI scientists, and engineers rather than traditional VC partners, and the firm markets a 'Scale-up Operating System' that shares the operating playbook Storonsky developed while scaling Revolut.

Sector Focus

QuantumLight backs founders across AI, Web3/crypto, fintech, SaaS, and healthtech. Its actual portfolio spans AI infrastructure (Together AI), consumer health/diagnostics (Function Health), AI-driven software engineering automation (Factory), legal technology (Robin AI), HR/employee benefits (Ben), clean energy (Fuse Energy), crypto payments infrastructure (Mesh), and additional fintech and IP-protection plays (Aspora, MarqVision). The unifying theme across sectors is a preference for AI-native or data-intensive businesses that Aleph's model flags as structural outliers, rather than a narrow vertical mandate.

Stage Focus

Public secondary sources place QuantumLight's typical entry at Seed through Series A, but the firm's own site frames its focus as growth equity and scale-up phase companies, and its visible portfolio activity (Series B rounds in Function Health, Fuse Energy, and Mesh) skews toward growth-stage, already-de-risked companies. QuantumLight appears comfortable across a wide band from early growth to late-stage scale-ups rather than true pre-seed/seed formation-stage investing.

Check Size

Check size is not publicly disclosed. Given fund sizes ($250M Fund I closed May 2025, $500M Fund II closed August 2026) and a strategy of backing a relatively concentrated set of ~27 companies to date, checks likely range from several million dollars at growth stage up to larger strategic/follow-on tickets, but this could not be confirmed from public sources.

Lead Tendency

Available evidence suggests QuantumLight most often participates in syndicates led by other investors rather than leading rounds itself: its investment in Mesh's $82M Series B was led by Paradigm, and Function Health's $298M Series B was led by Redpoint Ventures, with QuantumLight appearing as a portfolio investor rather than the round leader in both cases. This should be treated as a moderate-confidence signal rather than a firm rule.

Recent Activity

QuantumLight closed a $250M (€222M) debut fund in May 2025, then closed a $500M (€432M) second fund in August 2026, roughly 15 months later, with the raise reported as oversubscribed. The firm has backed approximately 27 companies to date, five of which have reached unicorn status. Recent disclosed portfolio activity includes Fuse Energy's ~$69.3M Series B (December 2025) and Function Health's $298M Series B at a $2.5B valuation (November 2025). QuantumLight is actively deploying from Fund II.

Portfolio Highlights

Notable portfolio companies include Together AI (AI infrastructure, unicorn), Function Health (consumer health diagnostics, $2.5B valuation), Factory (AI software engineering automation), Robin AI (legal AI), Ben (employee benefits platform), Fuse Energy (clean energy, reported ~$5B valuation), Mesh (crypto payments connectivity layer), Aspora, MarqVision, Exa, Tsuga, and Onyx. QuantumLight has backed five unicorns and reports two acquisitions within the portfolio, though specific acquirer/target details for those exits were not independently verifiable from public sources.

Team

Nik Storonsky, Founder — Founder and CEO of Revolut; provides the operating playbook and consumer-fintech scaling experience behind QuantumLight's 'Scale-up Operating System.'
Ilya Kondrashov, CEO & Co-Founder — Co-founded and ran QuantumLight day-to-day; previously co-founded Kriya Finance, a European B2B payments and pay-later company.
Maryna Omelchenko, Partner — Listed as Partner at QuantumLight per public professional profiles; specific investment focus not independently confirmed.

The firm positions itself as staffed by a broader bench of quant traders, AI scientists, and engineers beyond the three named principals above, but individual names beyond these three could not be confirmed from public sources.

Decision Process

With a small, concentrated leadership team (Storonsky, Kondrashov, and named partners) combined with an AI system (Aleph) that does substantial first-pass screening with limited human input, QuantumLight's process appears to be a hybrid of algorithmic sourcing and a small-partnership decision structure, rather than a traditional multi-partner investment committee.

Founder Preferences

QuantumLight's public materials emphasize identifying statistical outliers rather than a specific founder archetype; its own narrative centers on applying lessons from scaling Revolut to founders building ambitious, fast-growing technology companies.
