Core offering

YEAST is a French Association Loi 1901 that operates as a business angels network bringing together around thirty investor-entrepreneurs who finance and support innovative startups at the seed/amorçage stage. The network sources deal flow, organizes pitch sessions, conducts collective due diligence, and co-invests alongside member investors, partner networks (Est Angels, France Angels), and financial partners (Bpifrance, ILP) in startups located exclusively in the Grand Est region of France and Luxembourg.

Product overview

YEAST is a Business Angels network (réseau de business angels) based in the Grand Est region of France. Founded in 2013 in Lorraine, it operates as an Association Loi 1901 that connects individual angel investors with innovative startups at the seed/amorçage stage. The organization focuses exclusively on startups in the Grand Est region and Luxembourg. YEAST does not offer a traditional software product; rather, it provides deal-flow management, pitch sessions, investment facilitation, and networking services between entrepreneurs and investors. Key services include organizing pitch sessions, facilitating investor-entrepreneur introductions, deal co-investment with partner networks (Est Angels, France Angels), and portfolio company support.

Emerging players

• Anaxago: France-based online investment platform that crowds in individual investors for early-stage deals; competes for the same entrepreneur deal flow and individual investor capital that YEAST relies on, but uses a digital platform model rather than a club network.
• WiSEED: French online investment platform (CIP-AMF regulated) enabling retail investment in unlisted startups; addresses the same entrepreneur capital-need pain point as YEAST but via a tech-enabled marketplace, making it a structural alternative to club-based BA networks.

Broad incumbents

• Bpifrance: French public investment bank that co-invests alongside YEAST in portfolio companies (Albupad, Qfluidics, Passbolt, Fair&Smart). A key financial partner and deal co-investor; not a peer in the same model sense, but a structural counterparty whose funding terms and priorities shape YEAST's investment behavior.
• France Angels: National federation of French business angels networks, of which YEAST is a member. Provides shared deal flow, best-practice standards, and advocacy; not a direct investor but a structural super-peer setting industry norms and coordinating cross-regional co-investment.

Direct peers

• Reims Business Angels: Regional BA network in the Marne/Champagne sub-region, part of the Est Angels coordination. Directly comparable structure, geography focus, and seed-stage thesis, often syndicating Grand Est deals alongside YEAST.
• Champagne Ardenne Business Angels: Regional BA network covering the Champagne-Ardenne sub-region, member of the Est Angels coordination. Operates the same non-profit Association model, pools investor-entrepreneurs, and co-invests in startups across the broader Grand Est territory.
• Alsace Business Angels: Sister BA network in the Est Angels regional coordination; both networks co-invest frequently in Grand Est startups (e.g., Albupad, Entoinnov, Spartha Medical) and share the same regional investment thesis, federation membership, and operating model.
• Femmes Business Angels: Specialist French BA network with similar non-profit structure, seed-stage focus, and member-driven deal evaluation; YEAST co-invests and federates with FBA through France Angels, making it a directly comparable model with a thematic overlay.
• Arts et Métiers Business Angels: Fifth member of the Est Angels coordination; comparable alumni/industry-affiliated BA network investing at seed stage in Grand Est. Frequently co-leads and co-invests with YEAST, with similar ticket sizes and member-driven governance.
• Paris Business Angels: Largest French BA network by member count and capital deployed, based in Île-de-France. Operates the same Association-driven model with co-investment due diligence; co-invested alongside YEAST in APREX Solutions and represents a more mature scaled version of the YEAST model.
