Cologne, Germany, September 7, 2026 – In a move that signals a significant consolidation within the ESG (Environmental, Social, and Governance) services sector, Cologne-based Sustainability at Work Group has confirmed that the global investment firm Battery Ventures has acquired a majority stake in the company. This strategic partnership is designed to bolster the firm’s digital certification infrastructure and accelerate its international growth strategy across critical supply chain sectors, including renewable fuels, chemicals, food and feed, and sustainable packaging.
The transaction marks a pivotal chapter for Sustainability at Work, a firm that has established itself as a cornerstone in the administration of digital certification systems—tools that are increasingly essential for industries struggling to meet tightening global regulatory standards for sustainability. By integrating Battery Ventures’ financial backing and operational expertise, the group aims to scale its digital solutions to meet the escalating demand for verifiable supply chain transparency.
Strategic Rationale for the Partnership
The decision by Battery Ventures to secure a majority stake in Sustainability at Work is rooted in the firm’s long-standing thesis regarding the maturation of the "green economy." As multinational corporations face mounting pressure from regulators—such as the European Union’s Corporate Sustainability Due Diligence Directive (CSDDD)—the demand for third-party, verifiable certification of supply chains has shifted from a voluntary "best practice" to a mandatory compliance requirement.
Sustainability at Work operates at the intersection of regulatory compliance and technological infrastructure. Their proprietary systems provide the digital backbone for tracing the provenance of raw materials, ensuring that industries ranging from biofuels to complex chemical manufacturing can substantiate their sustainability claims. Battery Ventures, which has been active in the technology and industrial sectors since 1983, views this investment as a high-growth opportunity to digitize what has historically been a fragmented and analog industry.
Leadership Continuity and Governance
While the ownership structure has shifted, the leadership team at Sustainability at Work remains committed to operational continuity. Founders Jan Henke and Norbert Schmitz, who have steered the company through its formative years, will retain a significant stake in the business.
Under the new arrangement, Norbert Schmitz will maintain his role as managing director of the group’s core operational units, ensuring that the company’s internal standards for auditing and certification remain robust. Jan Henke’s mandate has been expanded, tasking him with the oversight of all companies within the Sustainability at Work umbrella. This dual leadership structure is intended to provide a bridge between the firm’s established reputation and the aggressive growth phase envisioned by Battery Ventures.
"This development creates a strong platform for long-term growth, closer collaboration, and innovation across the group, as we continue to serve our customers, regulators, and employees," stated Jan Henke. "We are building on a foundation of trust that has taken years to cultivate, and this partnership allows us to modernize our digital delivery systems to match the scale of the global challenges our clients face."
The Evolving Landscape of ESG Compliance
The timing of this investment coincides with a broader macroeconomic shift. According to recent data from global consultancy firms, the market for ESG software and digital auditing is expected to grow at a compound annual growth rate (CAGR) of over 15% through 2030. This growth is driven by the "transparency mandate"—the requirement for companies to provide granular data on carbon footprints, labor practices, and raw material sourcing.
In the renewable fuels sector, for instance, certification is no longer just about marketing; it is a prerequisite for market access. Regulatory frameworks like the Renewable Energy Directive (RED III) in Europe require rigorous certification of feedstocks to prevent deforestation and ensure life-cycle emission reductions. Sustainability at Work has positioned itself as a critical arbiter in this space, providing the digital "truth" that powers global energy markets.
Battery Ventures’ entry into this market is a calculated bet on the "Industrial Technology" vertical. Zack Smotherman, a general partner at Battery Ventures, highlighted the firm’s interest in the scalability of these services. "We see opportunities for organic growth and potential acquisitions in this critical market," Smotherman noted. "The market is expanding as governments and industry participants increasingly recognize the importance of sustainable supply chains. Battery’s team has deep experience in digital transformation, which we believe will complement the group’s existing strengths."
Chronology of Sustainability at Work
To understand the scale of this acquisition, it is necessary to look at the trajectory of Sustainability at Work:
- Foundation and Early Development: The group was formed to address the lack of standardized digital protocols in the rapidly evolving biofuel sector.
- Expansion Phase: The firm gradually diversified its service offerings to include chemicals, food, and packaging, moving away from being a single-industry service provider to a diversified sustainability infrastructure firm.
- Digital Transformation: Over the last three years, the group prioritized the development of proprietary, cloud-based certification systems, moving away from legacy paper-based auditing processes.
- 2026 Acquisition: The partnership with Battery Ventures marks the transition from an owner-led boutique firm to a portfolio company backed by one of the world’s most prominent tech-focused investment firms.
Implications for the Market
The acquisition is likely to trigger a ripple effect in the supply chain certification space. As Sustainability at Work expands its portfolio, it will likely pursue "bolt-on" acquisitions—smaller, niche certification providers that lack the digital infrastructure the group now possesses.
Furthermore, the involvement of a major player like Battery Ventures serves as a signal to the broader industrial sector. When top-tier venture capital and growth equity firms pour capital into ESG compliance, it typically indicates that the industry is nearing a "winner-take-all" phase. Smaller competitors may find it increasingly difficult to compete with the sheer technological, financial, and regulatory weight that the Sustainability at Work Group will now wield.
From the perspective of regulators and auditors, this consolidation is generally viewed as a positive development. A larger, better-funded entity is often more capable of investing in the security and integrity of its data systems, reducing the risk of fraud in certification processes. As supply chains become increasingly globalized and complex, the ability to rely on a single, highly scrutinized digital platform for compliance becomes a significant competitive advantage for clients.
Future Outlook and Strategic Objectives
Looking ahead, the collaboration between the founding team and Battery Ventures will focus on three primary pillars:
- Technological Acceleration: Leveraging AI and data analytics to automate the verification of supply chain inputs, thereby reducing the time and cost required for certification.
- Geographic Diversification: Expanding the group’s footprint outside of Europe, particularly in North America and Southeast Asia, where supply chain transparency regulations are rapidly evolving.
- Portfolio Diversification: Moving into new, high-growth sectors such as battery material recycling and circular economy metrics, which are becoming central to the global transition toward electric vehicles and sustainable infrastructure.
Norbert Schmitz underscored the importance of this technological transition, stating, "Battery’s team has deep experience in scaling technology businesses, and we feel this will complement the group’s existing strengths. We are extremely pleased to partner with them to bring our services to a global audience."
For Battery Ventures, this investment is consistent with its broader mandate of backing companies that define the future of industrial infrastructure. By supporting Sustainability at Work, the firm is effectively placing a long-term wager on the idea that sustainability is no longer a peripheral corporate activity, but the core operating system of the modern, globalized industrial economy. As the dust settles on this transaction, the market will be watching closely to see how quickly the group can translate this new infusion of capital into tangible market share.
