Questions & Answers

As answered by people managing CodePen and Soldera.

What's the story behind your product?

Soldera's answer:

Soldera emerged from failure. After experimentations in the carbon market that didn't work out, founders Stenver Jerkku and Al William Tammsaar faced a brutal reality check.

They'd spent a decade working on climate solutions together, starting when Stenver hired Al on the spot after he sketched neural networks on a café napkin. But timing killed their carbon venture, and the market wasn't operating with the integrity required to deliver genuine environmental impact.

Rather than pivot aimlessly, they systematically analyzed every environmental asset class. Their criteria: market maturity (could it be commodified?) and scale (could they have massive impact?). Guarantees of Origin hit both marks.

The concept itself is elegant. When you buy "green electricity," you're not actually getting green electrons. The grid mixes everything like water in an ocean. Guarantees of origin solve this through accounting: every megawatt-hour of renewable energy produced generates one GO certificate. Every megawatt-hour consumed retires one. It's government-mandated across Europe, used by AI data centers for ESG goals and required for regulatory subsidies. Simple in theory.

Stenver and Al went practical. They grabbed wine, visited friends with solar panels, and said: "Let us register your GOs." They bought the certificates, sold them, and immediately spotted the dysfunction. The market runs entirely over-the-counter. People texting spreadsheets, negotiating deals manually, drowning in paperwork. In Germany, you report metering data monthly. In Poland, you send physical papers to grid operators. One producer told them his capacity trader literally emails him to shut down machines when electricity prices go negative.

The data was stark: 30% of renewable energy producers weren't selling their GOs at all. Just leaving money on the floor. Small and medium producers either didn't know about the opportunity or couldn't handle the bureaucracy. Worse, large producers lost up to 60% of potential GO revenue due to limited market access and the disproportionate effort required for what amounts to 5-10% extra income.

Soldera's solution combines two mechanisms. First, an AI agent automates 95% of the work: registration, sales, paperwork, reporting, invoicing. Producers set high-level strategy; Soldera handles execution. Second, they aggregate all producers into a single counterparty, creating what Stenver calls a "global virtual renewable energy cooperative." Bigger volumes unlock better deals. Last month they moved 70 gigawatt hours, with volumes doubling or tripling monthly.

The trading philosophy is anti-speculation. Stenver saw too many producers try timing the market, holding 2023 production until now and losing 95% of value as prices collapsed from €8 to under €1 per megawatt-hour. Soldera pushes dollar-cost averaging: automated regular sales that capture average market prices without the bust-or-jackpot volatility.

Growth comes through the network effect. More participants mean bigger volumes, stronger negotiating power, better deals. Soldera's last tender had more participants than France's government auction.

The vision extends beyond Europe. As regulations standardize globally and hourly-based GOs replace yearly certificates, Soldera positions itself as the direct channel to producers, automating their back office while ensuring cash reaches those actually generating renewable energy.

What makes your product unique?

Soldera's answer:

Management is totally free

Soldera operates on a no upfront or software fees model known as our success fee. It means that Soldera's fees only kick in when producers successfully sell their Guarantees of Origin specifically using Soldera sales channels. Considering that the EAC market is currently extractive, opaque, and broker-driven, this aligns incentives perfectly between the platform and renewable energy producers, maximizing member freedom. Our auctions have a comparatively impressive performance again the broader market, and members always have the choice to use them or not.

Unmatched registry integrations

We're integrated across European registries - even where nobody else is. Soldera's platform acts as a "registry of registries," consolidating data from 30+ registries through a streamlined device overview so producers avoid juggling multiple logins. This unified cross-registry view is complemented by integrated market intelligence through quarterly market outlooks that link directly with trading strategy features like hedging.

Constantly rolling out intuitive automations

The platform delivers deep automation across the entire GO value chain, from device registration and contracting to transfers, invoicing, reconciliation, and reporting, reducing back-office work by approximately 95%.

Sheer aggregate volume means unrivalled market access

We're growingly rapidly, and our members benefit as a result of sheer volumes managed. Through aggregated market access, Soldera pools volume and runs sealed-hybrid tenders that secure better bids and access to institutional buyers, enabling premium pricing for producers that otherwise they simply wouldn't reach.

We know where to look to identifying revenue gaps

Soldera also automates quality label and ecolabel eligibility checks, ensuring that qualifying volumes aren't overlooked. Already trusted by 3,000+ renewable production sites across Europe, the platform has demonstrated scalable, trustworthy adoption in the market.

Why should a person choose your product over its competitors?

Soldera's answer:

Because this service shouldn't cost you a limb

Others are already charging thousands for the services we provide for free. Choosing Soldera means the ability to test the waters, with zero financial risk or barrier to entry: our total lack of setup fees make it accessible for energy producers of any size. The platform automates tedious, error-prone processes across multiple registries, freeing staff from administrative burden while reducing mistakes.

By participating in Soldera's aggregated pools, even individually small producers gain access to premium buyers and better pricing that would be unavailable to them independently. Unlike opaque intermediation, Soldera provides transparent price discovery through its tender process, while built-in market intelligence enables data-driven decisions rather than guesswork.

The platform's proven scale, with thousands of producers and battle-tested processes across jurisdictions, demonstrates reliability and maturity that newer entrants cannot match. Producers can learn how to make the most profit from GO sales through Soldera's comprehensive approach.

How would you describe the primary audience of your product?

Soldera's answer:

Energy producers of any size who want extra income

Soldera's primary audience consists of renewable energy producers, spanning solar, wind, hydro, and biomass facilities, who generate or want to generate Guarantees of Origin and want to monetize them efficiently. These producers range from small and medium operators to large, multi-SPV portfolios requiring scalable, automated operations.

The platform particularly serves producers operating across multiple jurisdictions and registries through cross-border GO management who need cross-registry consolidation and compliance support. Risk and commercial teams seeking integrated market intelligence, hedging tools, and strategic insights to optimize their GO strategy also form a key part of the audience.

Soldera is backed by leading investors and backed by a diverse range of partners across the renewable energy ecosystem.

  • Saules Energy
  • Nuveen
  • BaltCap
  • Kaamos Energy
  • Merito
  • Sunsa
  • Vestman

Which are the primary technologies used for building your product?

Soldera's answer:

We're powered by AI, and security always comes first

Soldera's platform is built on a foundation of secure, EU-based infrastructure with sophisticated AI-powered automation. The backend runs on Google Cloud servers located in the EU, inheriting Google's ISO certifications including ISO 27001, 27017, and 27018. For clients with specific regulatory requirements, Soldera can deploy local, on-premises AI servers to ensure data never touches U.S. infrastructure.

The platform leverages the Gemini API for AI processing, with a critical security benefit: under Gemini's paid API terms, prompts and responses are never used to train Google's general models. Each PPA or GO statement is handled in an isolated session, documents don't train Soldera's models, and data is never shared across clients. After processing, documents are cleared from working memory. All data is encrypted in transit and at rest, with access control enforced via single sign-on (SSO) and role-based permissions.

Soldera's AI contract parsing respects legal meaning by extracting terms such as delivery schedules and forward sales that map precisely to registry operations like GO issuance, transfer, or cancellation. Users retain control through options to process contracts manually or require human approval steps. Every action leaves an audit trail, and Soldera positions itself as an "open book" on AI security, inviting clients or auditors to review architecture diagrams and technical implementations.

Additional details can be found in the Soldera privacy policy and through their comprehensive feature documentation.
