What Deltablock does

DeltaBlock is a Paris-based fintech founded in 2019 that provides algorithmic liquidity enhancement services for small and mid-cap listed companies. The company targets exchange-listed SMEs with sub-billion-dollar market capitalization that face limited trading liquidity, wide bid-ask spreads, and reduced investor confidence. It operates from a strategic headquarters in Paris, France, with an operational hub in Singapore serving the Asia Pacific region.

The company's core offering is the DeltaBlock Liquidity Platform, built on seven years of proprietary market microstructure research and incorporating AI-driven algorithms, self-learning optimization loops, real-time market analysis, and regulatory compliance logic. Supporting components include a Real-Time Dashboard for live liquidity monitoring and a Liquidity Analysis Report providing customized strategic advice. Demonstrated outcomes include over 50% reduction in bid-ask spreads on the Singapore Exchange for certain mid-cap stocks and a claimed 2x liquidity improvement using five times fewer financial resources than traditional market-making approaches.

DeltaBlock operates a sales-led, enterprise-focused B2B go-to-market targeting listed SMEs through direct engagement, with CTAs such as 'Book A Demo' and 'Request A Report.' Revenue is generated through subscription/recurring fees for liquidity enhancement services, though no public pricing tiers are disclosed. The company raised €1.25 million in seed funding in May 2024 from Blast.Club (lead), Entrepreneur First, and Index Ventures, with stated use of funds directed at R&D and expansion across Europe and Asia. The company was recognized by Global Finance Magazine with Innovator Awards in 2026.
