Seltz closed a $12.5 million seed round in June 2026, backed by Speedinvest, B Capital, Italian Founders Fund, United Ventures, and Future Back Ventures β an investor lineup spanning both US and European funds.
The round is a modest one by 2026's headline standards, where nine-figure checks have become common in AI infrastructure and healthcare. But the multinational investor base signals something founders should pay attention to: early-stage capital is increasingly willing to cross the Atlantic when a team shows the right combination of technical depth and market focus, rather than staying confined to purely domestic seed rounds.
Seltz's raise arrived the same week as several other seed and early Series A rounds in AI-adjacent categories, part of a broader June funding tape that skewed heavily toward production AI systems β tools built to make real operational decisions rather than demo well.
For early-stage founders, the takeaway from rounds like Seltz's is less about the size of the check and more about who's willing to write it together: cross-border syndicates are becoming a normal part of how serious seed rounds get built in 2026.
