helios.do Tech Stack

Climate-focused neobank financing sustainable projects across Europe

Financial Services Paris, Île-de-France 11–50 employees Founded 2019 Privately Held

Helios is a French neobank built around environmental screening and impact investing—routing customer deposits exclusively into renewable energy, sustainable agriculture, and circular-economy projects rather than fossil fuels or industrial agriculture. The hiring profile (marketing-heavy, all interns) and active projects (email campaigns, landing-page conversion, CRM automation) reveal a pre-product-market-fit stage focused on user acquisition and retention; the tech stack (Customer.io, Storyblok, WordPress, Kotlin/TypeScript backend) is typical for early fintech but notably lacks specialized banking infrastructure, suggesting reliance on third-party integrations for core payments and compliance.

About helios.do

Helios operates a retail neobank serving individual customers in France, with product lines spanning checking accounts (including youth and joint variants), money-management tools (budgeting, merchant networks), and savings products (investment accounts and life insurance). The company's stated mission is to redirect bank financing toward ecological transition—blocking investments in coal, oil extraction, intensive livestock, and synthetic pesticides while exclusively funding renewable energy, regenerative agriculture, plastic recycling, and low-carbon transport. The organization is 11–50 people, founded in 2019, based in Paris. As of the data snapshot, the company reports €8M deployed into transition-focused projects. Compliance challenges (fraud, anti-money-laundering, sanctions screening) are active internal concerns.
