Symbiose 53

What Symbiose 53 does

Symbiose 53 is a nonprofit Business Angels network (association loi 1901) headquartered in Laval, Mayenne, France, founded in 2007 by regional industrial entrepreneur Jean Heaume. It federates 30+ individual investors who collectively evaluate, fund, and support early-stage companies and growing SMEs in the Mayenne department, with individual investment tickets ranging from €5,000 to €50,000 and total round sizes typically between €200,000 and €2,000,000. Since inception, the network has deployed €1.7M across 18 portfolio companies spanning sectors including medical, digital, IOT, industry, cleantech, robotics, and mental health technology.

The network operates as a generalist investor, taking minority equity stakes and providing post-investment support through board representation, quarterly reporting, and access to member expertise. It is a member of the France Angels federation, which provides national best-practice standards and deal flow, and it partners with CCI de la Mayenne for administration, Laval Mayenne Technopole (LMT) for tech startup sourcing, Le Village By CA for accelerator access, and KPMG for advisory support. Deal flow is sourced via regional partnerships, organized pitch events, and referrals from co-investment networks.

Economically, Symbiose 53 generates no revenue; it is a capital coordination and governance structure for individual investors. Returns accrue to members through equity appreciation and exits (typically within 5–7 years), with portfolio examples including Tennaxia (software, exited via buyback), Neolix (energy, now profitable), and PepPsy (mental health app, launched 2022). The organization's sustainability therefore depends on continued member recruitment and quality deal flow rather than commercial monetisation.
