“There are billions of dollars at stake in solar. So why are so few lenders paying attention?”
That question, posed by Eduardo Donadi on LinkedIn, is more than a challenge, it’s a thesis. As a fintech entrepreneur and investor based in São Paulo, Donadi has spent the last decade building companies that unlock capital for underserved markets. From supply chain finance to clean energy lending, he’s turning capital inefficiencies into growth opportunities.
Through his ventures, Liber Capital and Eos Loan, Donadi is driving financial innovation in two of Brazil’s most critical sectors: small business operations and residential solar energy. And with a background in both B2B factoring and environmental finance, he’s not just riding waves, he’s creating them.
“We started with just R$300K. Now we’re solving real problems for suppliers.”
In 2017, Donadi co-founded Liber Capital, a reverse factoring and digital lending platform that helps small and mid-sized suppliers access capital faster. What began with just R$300,000 in startup funds has grown into a platform with a reported net worth of R$4.3 million, according to Donadi’s F6S profile.
Liber Capital isn’t a bank, and that’s the point. Donadi positioned the company as a modern alternative to Brazil’s slow-moving SMB finance sector. By digitizing the approval and payout processes for supplier invoices, Liber makes it possible for small businesses to receive payments almost instantly, without needing a credit line from traditional institutions.
The results? Faster business growth for suppliers. Stronger supply chain reliability for enterprises. And a rising profile for Donadi as one of Brazil’s sharpest fintech operators.
“According to Donadi, only around 3% of lenders are tapping into solar, and that’s a missed opportunity”
Donadi didn’t stop with enterprise finance. His second venture, Eos Loan, is laser-focused on unlocking the solar economy.
As CEO and founder, he leads efforts to provide residential solar financing, an area that, in his words, is “wildly underpenetrated” by traditional lenders. Through Eos Loan, Donadi is helping homeowners install solar panels by spreading costs over accessible loan packages.
He frequently points out that only ~3% of loan providers in the U.S. engage in solar lending, despite forecasts suggesting over $300 billion will flow into residential solar by 2035. Brazil, facing similar energy transitions, is equally poised for this transformation, and Donadi’s work is helping accelerate adoption.
“I’ve built in fintech, fashion, and factoring. But the goal is always the same, create leverage for others.”
Donadi’s career reflects a deep versatility. Before launching Liber Capital and Eos Loan, he built ventures like DUX Factoring and Zerah P, dabbling in fashion and niche financial services. While not all were headline-grabbing, each step helped him understand where Brazilian markets lacked flexibility, and where tech-enabled platforms could bring change.
That’s what sets Donadi apart: he’s not just a founder, he’s an ecosystem builder. He understands Brazil’s regulatory hurdles, capital barriers, and infrastructure bottlenecks. And instead of waiting for better conditions, he builds companies that solve around them.
“You have to share the data. The more we all see it, the faster the sector grows.”
On LinkedIn, Donadi is more than a CEO, he’s a teacher. With nearly 4,800 followers, his posts break down complex lending trends, white papers on solar investment, and emerging fintech behaviors.
His most popular content is often educational, such as highlighting investor blind spots in solar lending or explaining how reverse factoring impacts small business survival rates. His tone is pragmatic, his insights sharp, and they’re helping create a more informed entrepreneurial community across Latin America.
More Than Capital, Catalyst
Eduardo Donadi’s impact can’t be measured by valuations alone. His legacy lies in how he’s moved capital to where it was previously inaccessible. Whether it’s a rural supplier waiting 60 days for invoice payment, or a homeowner needing financing to switch to solar, Donadi builds the infrastructure that says “yes.”
With Liber Capital, he’s reshaping how enterprises think about supply chain liquidity. With Eos Loan, he’s tackling the future of decentralized energy. And across both, he’s proving that good lending isn’t just about risk, it’s about opportunity.
