Tartu-based cleantech startup Soldera has secured €1.6 million in non-dilutive funding from Estonian Enterprise Agency to build AI-powered infrastructure unifying Europe’s fragmented renewable energy certificate registries, shortly after surpassing €1 million in annual revenue in 2025. The grant will be used to deepen product development, automate integrations across 30+ national registries, and scale the team as Soldera tackles a market still reliant on manual, country-by-country processes. The funding follows the company’s oversubscribed €2.5 million raise led by Lifeline Ventures, Alumni Ventures, and Lemonade Stand, underscoring growing investor confidence in Soldera’s mission to unlock new revenue for renewable energy producers, improve transparency for corporate buyers, and strengthen European energy security through a single, unified certificate management platform.
Soldera automates the management, trading, and retirement of renewable energy certificates, connecting buyers and producers through a single AI-driven interface. Today, Europe’s certificate market spans more than 30 national registries, many of which lack APIs and still operate using spreadsheets or even paper-based processes. Opening and maintaining registry accounts can cost companies up to €5,000 per country annually, while transactions are often conducted via email or phone calls—conditions that Soldera describes as “a commodity market stuck in time.”
By unifying registry access and automating certificate flows, Soldera aims to unlock additional revenue for renewable energy producers, improve transparency for corporate buyers, and channel more investment into local renewable projects—while also strengthening European energy security.
The company’s traction suggests the market is ready. In 2025, Soldera scaled revenue from €150,000 to €1 million, achieving consistent 30% month-over-month growth. Its platform is now used by Fortune 500 companies, a global top-20 asset management firm, and more than 500 corporate buyers across 15+ regions, connecting them to over 4,000 renewable power plants. Certificates from multiple registries appear in a single dashboard, with AI systems executing purchases and retiring certificates autonomously.
“We’re set to capture a $13B market on track to hit $80B by 2030,” said Stenver Jerkku, Founder & CEO. “This fully depends on onboarding A-players and AI progress. We only hire the best and our dream is building a billion dollar company with less than 30 people.”
To that end, the company plans to use the €1.6 million grant primarily for applied research and product development, while continuing to expand its 11-person team across engineering, product, and go-to-market roles. Soldera operates with a trust-centric, low-hierarchy culture that has already attracted talent from companies including Bolt, Trimble, LHV, and Glia.
“We’ve built an ethos of continuous improvement,” writes Oliver Bonallack, Growth Marketer at Soldera. “It’s a complex industry, so there are no stupid questions. And with such a high density of talent and focus, nobody has the time to breathe down your neck. You know your priorities and are given the freedom to execute”.
As regulatory pressure mounts on corporates to decarbonise and demand for high-quality renewable certificates grows, Soldera is betting that infrastructure—not marketplaces alone—will define the next phase of Europe’s energy transition. With fresh non-dilutive capital in hand and strong commercial momentum, the company is now racing to turn one of Europe’s most fragmented climate markets into a unified, automated system fit for scale.
