Elaia closes €134M deep tech seed fund, double its previous vehicles
What's the deal? French VC Elaia has closed its third deep tech seed fund, Deep Tech Seed 3 (DTS3), at €134 million — twice the size of its two previous deep tech funds. The Paris-based firm will deploy between €1 million and €13 million per company into pre-seed and seed-stage B2B startups across Europe, targeting computing, industrial innovation, and life sciences.
The fund was built in partnership with leading European research institutions, including PSL UniversitéDealroom has a profile for this one. Try Dealroom →, INRIADealroom has a profile for this one.

Why now? DTS3 has been active since its first close of €60 million in March 2024, and has already deployed capital into 11 companies. The final close brings the fund to its full size and accelerates a deployment phase already well under way.
The timing reflects a broader shift in European deep tech. In December 2025, new energy and advanced manufacturing sectors attracted record investment, and European deep tech hubs from Zurich to Paris are producing increasingly competitive founding teams.
What could go wrong? Deep tech investing is slow and capital-intensive by nature. Translating laboratory breakthroughs into scalable products can take a decade or more, and the fund's €1 million to €13 million ticket sizes may not be sufficient to carry companies through to later, more expensive development stages. Without strong follow-on support — either from Elaia's own later-stage vehicles or co-investors — portfolio companies risk stalling.
The signal: DTS3 doubling the size of Elaia's prior deep tech funds is a clear sign that institutional appetite for early-stage science-led investing in Europe is growing. The fund's model — embedding itself inside top research institutions to source founders before anyone else — is a differentiated bet on pipeline rather than price.
With €1 billion under management and more than 100 portfolio companies, Elaia is positioning itself as Europe's go-to partner for the lab-to-market journey. That model has already produced exits including Mablink BioscienceDealroom has a profile for this one. Try Dealroom →, acquired by Eli LillyDealroom has a profile for this one.
