Litto Invest
Litto Invest is a small French venture-capital fund for the coastal and maritime economy, created in 2015 and based near Nantes. It backs blue-economy and energy-transition companies across the Pays de la Loire region. Its water exposure is narrow: the Leviathan database tracks two water companies it has backed, sensor maker Weenat and water-purification startup Fonto de Vivo.

The take
Litto Invest was built for the coastline, and the name says so: littoral. The fund was created in 2015 by the Pays de la Loire Region, Banque Populaire Grand Ouest and EDF to put equity into the maritime and coastal economy of France's Atlantic west, everything from fishing and boatyards to marine energy. Water, for Litto Invest, is one strand of a wider blue-economy mandate, not the whole job.
Litto Invest is a societe de capital-risque, which is simply France's legal name for a venture-capital company, and it is run day to day by GO Capital, a western-France manager that operates a small family of regional blue-growth funds for the Banques Populaires. The cheques are deliberately small and local, roughly 150,000 to 500,000 euros into young companies that promise to anchor jobs in the region. Its two water names read like that coastal brief in miniature: Weenat, whose connected sensors tell farmers when to hold off irrigating, and Fonto de Vivo, whose hand-operated kit turns unsafe water into drinking water.
Litto Invest is best read, by a newcomer to water, as a patient regional fund whose water exposure falls out of a coastal mission rather than a water thesis. The most recent water deal Leviathan has on file is from 2019, so this is a standing portfolio to study, not a hot cheque-book to pitch this quarter. What it still represents is a particular kind of money: small, local, blue-economy equity that treats water as part of a working coastline, backed by regional banks and a public region rather than by a fund chasing the category.

Frequently asked
- What does Litto Invest invest in?
- Litto Invest invests in the coastal and maritime blue economy and the energy transition across France's Pays de la Loire region, taking small minority equity stakes in young companies. Its water-related holdings in the Leviathan database are Weenat, an agricultural-sensor maker, and Fonto de Vivo, which builds portable water-purification kits.
- Who runs Litto Invest?
- Litto Invest is managed under delegation by GO Capital, an independent venture-capital firm in western France, and its investment director is Hervé Bachelot Lallier, a GO Capital partner who helped set up the fund in 2015 after years in corporate finance at Natixis and Banque Populaire Atlantique.
- Where is Litto Invest based and how big is it?
- Litto Invest is based in Saint-Herblain, on the edge of Nantes in western France, and was created in 2015. It is a small fund, managing more than 7 million euros, and writes cheques of roughly 150,000 to 500,000 euros, rising toward 1 million with follow-on investment, meaning later cheques into the same company.
- Is Litto Invest a water investor?
- Litto Invest is a regional blue-economy fund, not a water specialist. Water reaches its portfolio through a broader coastal and maritime mission rather than a dedicated water thesis. The Leviathan database tracks two water companies it backed, Weenat and Fonto de Vivo, both around 2019, rather than a steady stream of water deals.
- Is Litto Invest the same as GO Capital?
- No. Litto Invest is one specific regional fund, a société de capital-risque created in 2015 for the Pays de la Loire coastline. GO Capital is the larger management company that runs Litto Invest alongside sister blue-growth funds such as Mer Invest and Sud Mer Invest for the Banques Populaires.
