- QuantumLight has closed its second fund at $500 million, surpassing its original goal.
- This new fund is double the size of QuantumLight’s first fund, which raised $250 million in 2025.
- Aleph, the AI model developed by Storonsky, reviews investment opportunities with little human input.
QuantumLight, a London investment firm co-founded by Nik Storonsky in 2023, has closed its second fund at $500 million, according to Sifted. Chief executive Ilya Kondrashov said the fund was oversubscribed.
This closing comes 15 months after QuantumLight’s first fund reached $250 million in May 2025, and about seven months after industry reports revealed the firm was preparing for a second round.
Moving from initial discussions to a $500 million oversubscribed close in just six months, while doubling the fund size, is notable. Investors are eager to participate.
QuantumLight uses Aleph, its in-house AI model, to evaluate growth-stage companies with little human intervention. The firm invests in AI, fintech, SaaS, healthtech, and deep tech, and has supported 27 companies so far, including five unicorns.
The portfolio features companies like Together AI, Function Health, Factory, Robin AI, Ben, and Fuse Energy, which was recently valued at $5 billion.
QuantumLight’s earliest investments are less than three years old, and it usually takes years for venture returns to appear. This fundraising shows trust in Storonsky’s reputation and Aleph’s promise, rather than in proven results. As Kondrashov has said before, the firm is still young, has a short track record, and is counting on the model to keep improving.
It remains unclear whether Aleph can outperform experienced partners over a full investment cycle. With this new $500 million fund, QuantumLight now has the means to find out.
