EIC matchmaking, a corporate partner and a €11 million cheque: Nesta and Circularise move to put traceability into circular polymers and chemicals

A November 2021 European Innovation Council Corporate Day proved decisive for a Dutch traceability start-up and a leading renewables refiner. Circularise, a Hague-based provider of digital product passports and mass balance bookkeeping software, met representatives from Neste during the EIC matchmaking event. That initial contact matured into a collaboration announced in May 2022 and, within a year, into a Series A style financing round in which Neste joined Brightlands Venture Partners, Asahi Kasei, existing investor 4impact and others to invest a combined €11 million in Circularise. The deal combines private capital and EU grants and is pitched as a way to accelerate traceability, verification and the scale-up of circular feedstocks in polymers and chemicals.

How the connection was made and what role the EIC played

The first contact between the two organisations happened at an EIC Corporate Day on 23-24 November 2021. Circularise had responded to an open challenge set by Neste to identify digital solutions capable of supporting circular supply chains. The EIC describes Corporate Days as curated matchmaking events run through its Business Acceleration Services to connect EIC-funded innovators with decision makers at large companies.

Both sides describe the EIC event as the seed that allowed Nesta and Circularise to find common ground. From there, they ran proofs of concept with supply-chain partners and tested integration with ISCC Plus certification processes. Company executives say those pilots helped move the relationship from idea to commercial engagement and investment.

The partnership and the financing

In May 2022 Neste and Circularise announced a collaboration to deploy Circularise’s traceability platform across circular and biological polymer and chemicals value chains. The stated aim is to trace renewable and recycled material flows and to increase transparency across complex supply chains. In November 2022 a group of corporate and venture investors announced a combined €11 million financing into Circularise to accelerate the company's product development and market expansion. The round included Brightlands Venture Partners, Asahi Kasei, Neste and 4impact capital, and was supplemented by European Commission grants.

What Circularise technology does and why corporates are interested

Circularise offers a software stack for traceability and selective data sharing across multi-tier supply chains. The company builds a digital twin of physical materials, records provenance and processing steps, supports mass balance bookkeeping, and gives brands and suppliers tools to share verifiable sustainability data while limiting exposure of confidential commercial details. Neste and other partners are interested because polymers and chemicals supply chains are complex, involve co-processing and blending, and currently rely heavily on trust and mass balance allocations to attribute renewable or recycled content.

Circularise says it protects supplier confidentiality through its proprietary Smart Questioning method that allows selective disclosure of credentials and data to authorised parties. The combination of selective sharing and ledger-backed attestation is presented as a way to let brands and auditors verify sustainability attributes while preserving commercially sensitive information.

Standards, certification and pilots

One of the partnership activities involved a pilot with ISCC Plus certification. ISCC is an existing certification scheme focusing on sustainable and traceable biomass and circular feedstocks. Participants in the pilot tested how a blockchain-backed system could complement ISCC Plus audits by making certification data more readily available and auditable across supply-chain actors.

Pilots and proofs of concept with supply-chain partners are an important intermediate step. They are necessary to test the data model, verify how mass balance is documented, confirm the selective disclosure mechanisms work in practice, and check whether auditors and certifiers accept the format and provenance proofs. In other words, technical pilots do not guarantee uptake. Standards alignment, auditor acceptance, supplier onboarding and the economics of collecting primary data all remain practical hurdles.

Why Neste took a stake and why corporates are betting on traceability

Neste framed the partnership as part of a strategic push to bring renewable and recycled feedstocks into polymers and chemicals markets. For a refiner and feedstock supplier, being able to demonstrate the integrity of renewable inputs upstream is essential for gaining customers and meeting tightening regulatory and corporate reporting requirements. Corporate backers in the financing round cited the need for scalable digital solutions that increase visibility and trust in material flows.

Circularise’s founders and investors argue the technology helps turn sustainability from a ‘‘trust game’’ into a ‘‘data-backed game’’. That language reflects a wider commercial reality. Brands need data to substantiate claims for regulators, buyers and customers. Investors and corporates want mechanisms that reduce reputational and regulatory risk and that can scale into industrial practice.

Where the value and the risks lie

Potential value points include improved audit efficiency, verified Scope 3 data for corporate greenhouse gas accounting, streamlined mass balance reporting, and stronger signals for buyers to pay premiums for verified recycled or renewable content. For system-level impact the technology must also be interoperable with other traceability initiatives, accepted by certification schemes and embedded in procurement practices.

Risks and constraints are real and should temper expectations. They include the operational burden on small suppliers to provide primary data, the legal and commercial sensitivity of detailed bills of materials, uneven digital readiness across supplier tiers, the need for agreed standards and interoperability, and the question of which certifiers and auditors will accept ledger-based proofs. Additionally, public blockchain-based verification raises governance questions about which networks are used and what consensus mechanisms they employ. Those choices affect scalability, latency and energy profiles and therefore are material to any sustainability claim.

EIC’s role and the broader funding landscape

This case is also an example of the EIC’s strategy to combine grant support with business acceleration, matchmaking and investor outreach. Circularise previously received EIC support amounting to €1,502,331 according to EIC materials. The EIC Corporate Partnership Programme is designed to bring large corporates, EIC awardees and investors together to test pilots, sign commercial agreements and, where appropriate, mobilise follow-on capital.

Outlook: tech, standards and the long road from pilot to industry practice

The Nesta-Circularise story shows how curated matchmaking can unlock corporate engagement and channel private capital into niche digital infrastructure for circularity. It also shows that piloting with certification schemes and running proofs of concept are necessary but not sufficient steps. Wider adoption requires alignment on standards, auditor acceptance, integration into procurement and product flows, and the ability to reduce supplier friction in data submission.

For Circularise, the €11 million round should provide headroom to develop product features such as mass balance automation, integrations with life cycle assessment tools, and customer onboarding processes. For industrial partners such as Neste, the partnership is a hedge against supplier opacity and a building block for scaling renewable and recycled feedstocks into larger markets. For the wider EU policy agenda it is an example of how public grant programmes, corporate partnerships and venture finance can converge around a common problem.

Bottom line

The collaboration between Circularise and Neste, seeded at an EIC Corporate Day and followed by pilots and an investor syndicate, illustrates the concrete outcomes the EIC aims to create by matchmaking startups with corporates. It also highlights the longer term challenges. Technical solutions such as ledger-backed digital product passports are necessary to improve traceability. They will not by themselves guarantee industrial scale circularity without accepted standards, auditing practices, supplier engagement models and transparent governance of the digital layers used to underpin trust.
