A debut fund that doubled in fifteen months
QuantumLight closed its second fund at 432 million euros, or 500 million dollars, announced August 17-18, 2026. The London-based venture firm was co-founded in 2023 by Nik Storonsky, who remains chief executive of digital bank Revolut, alongside a team built around a quantitative, data-first approach to picking startups. Fund II is more than double the 222 million euro debut fund QuantumLight closed in May 2025, and it closed oversubscribed, above the firm's original target.
The pace is the notable part. Fifteen months separate a 222 million euro debut close from a 432 million euro follow-on, a doubling that venture firms built around individual partners rarely manage that fast, since it usually takes years to prove a track record long enough to justify twice the check size from limited partners.
Aleph, the model that screens the deals
QuantumLight's edge is Aleph, a proprietary AI system that the firm says tracks more than 700,000 venture-backed companies against upwards of 10 billion data points, surfacing and ranking investment candidates before a human partner ever looks at a deal. QuantumLight has said all of its most recent investments were sourced or recommended by Aleph, with partner involvement concentrated on final diligence and terms rather than on where to look in the first place.
That is a structurally different model from a traditional venture partnership, where deal flow runs through a small number of individual partners' networks and judgment calls. QuantumLight is closer in mechanics to a systematic hedge fund that happens to write venture checks: rules and data drive the screening, and the humans sign off at the end rather than run the search.
Why this matters beyond the venture industry
The obvious read is a funding story: a well-known founder's new firm raised a bigger fund, faster, than its first. The less obvious read is for anyone outside venture capital who buys software. QuantumLight's 27 portfolio companies, five of them unicorns, are potential vendors, competitors, or acquirers in an EU business's own market, and doubled dry powder means QuantumLight can write more, and larger, checks into that pool over the next few years.
A company underwritten by an algorithm on a quant fund's timeline is not automatically less stable than one backed by a traditional partnership, but it is differently stable. Its funding pace can move faster than the relationship-building and reference-checking that usually accompanies a VC round, so the diligence signals a buyer is used to reading, a lead partner's public backing, a board seat, a multi-round relationship, may simply not be there in the same form. An EU owner evaluating a new AI or SaaS vendor backed by a fund like QuantumLight should ask directly how the deal was sourced and who, if anyone, is accountable for it beyond the algorithm, rather than assuming the checks that apply to a traditional VC-backed company automatically apply here.
The wider bet: algorithmic venture capital is no longer a niche approach
Other firms are experimenting with algorithm-led investing too. QuantumLight's fund size remains modest next to the largest generalist venture firms, yet it is now large enough to be a genuine allocator of capital across AI, fintech and SaaS in Europe. Storonsky has said the goal is for QuantumLight to prove that data-driven investing can outperform instinct-driven investing over a full cycle, and an oversubscribed second close is the clearest signal yet that institutional investors are willing to fund that experiment at scale.
For the wider European tech market, a second, larger algorithmic fund closing successfully lowers the bar for the next one. If QuantumLight's model keeps producing unicorns at its current rate, expect more limited partners to back systematic, low-touch venture strategies, which means EU founders and the vendors they eventually compete with will increasingly be underwritten by code as much as by conversation.
