Founders and co-founders always use Le Main de Dieu free forever. No subscription, ever.
Angel investors, university-affiliated funds, and organisations that back founders on equity-free or very-low-equity terms — you join free forever.
Same for small commercial partners — prototyping shops, engineering firms, manufacturers — who help deep-tech teams build prototypes on zero-equity or venture-client terms. No subscription. No commission.
Le Main de Dieu connects deep-tech founders with the cofounder, capital, industrial capabilities and market access required to turn difficult technologies into real-world impact.
A connection layer built specifically for technologies that require capital, industrial capabilities and market access to become real-world products.
Connect with Cofounders, investors and commercialization partners that match what your technology actually needs — from funding and strategic expertise to engineering, manufacturing, supply chain, market access and deployment.
Match with brilliant scientific founders who have breakthrough technology but need your commercial, operational, or industry expertise to build the business. Find the exact capability gap where you can drive impact.
Find deep-tech companies that match your active investment mandate—not a generic startup directory. Find deep-tech companies with active investment mandates aligned with your investment focus, stage, geography, technology and strategic interests.
Connect with companies looking for the capabilities to build, industrialize, validate, integrate, distribute or commercialize their technology. Manufacturing, industrialization, distribution, integration, regulatory and strategic capabilities all belong here.
Le Main separates who you are from what you need right now. Your master profile establishes the context; your active mandate tells the network what you are actively looking for or can provide.
Tell us who you are, what you build, invest in or provide.
Specify the opportunity, capability or relationship you are looking for.
Matching considers both sides and the requirements of the specific mandate.
Request an introduction when a potential counterpart is relevant.
Both sides decide whether they want to connect.
The relationship moves beyond the platform and into the real world.
Deep-tech commercialization often depends on capabilities that cannot be captured by a simple industry tag. Le Main is designed around the specific mandates, constraints and capabilities behind each relationship.
See How It Works →Matches are built around what each side is actively looking for or able to provide.
Participants can share supporting evidence so counterparties can decide what they want to review.
Participants control what information is visible and when additional information can be shared.
Introductions happen only when both sides choose to engage.

Le Main does not independently verify participant-provided information. Instead, participants may attach supporting evidence and control who can see it. Counterparties decide what they require before engaging.
Not generic networking.
Not another marketplace.
Le Main de Dieu is a mandate-driven connection layer built specifically for deep-tech.
