ESG due diligence that holds up in the investment committee
For venture capital funds and Series A+ startups: a systematic, third-party-validated assessment of material sustainability risks, in four to five weeks. Decision-ready for the investment committee and exit-proof, not compliance-driven. Because I invest in startups myself, I deliver the memo in the language decisions are made in at the IC table.
Materiality Assessment: Why Series A+ investments need systematic ESG review
A Sustainability Risk is an environmental, social, or governance event that, if it occurs, can have a material negative impact on the value of an investment. The regulatory cascade has arrived: SFDR 2.0 is set to significantly tighten disclosure requirements for sustainability-related funds. The proposal is still moving through the EU legislative process, with application expected from 2028.
The current Article 6/8/9 categories are set to be replaced by new product labels ("Transition", "ESG Basics", "Sustainable"), with a 70% minimum portfolio quota and binding exclusion criteria for fossil activities. Funds marketed to professional investors only may be able to opt out of the new categorisation, but the pressure simply shifts: LPs demand audit-proof portfolio data by the next closing at the latest, and exit buyers price material ESG risks hard into valuations or treat them as deal-breakers.
I don't look at ESG risk only as a consultant: across my own angel portfolio I have seen how material sustainability risks can carry an investment case or sink it. The signals that matter at the IC table are the ones I check first.
Sustainability Risks → Financial Impact
Business models that become unprofitable through CO₂ pricing or physical climate risks. Studies show: Material sustainability risks correlate with 15-25% lower valuations at exit.
Reputational Risk
A supply chain scandal or greenwashing accusation can make Series B impossible. Post-deal integration of undiscovered ESG risks costs 10x preventive due diligence.
Green Premium vs. Brown Discount
ESG-mature companies consistently achieve "Green Premium" at exits, while ESG laggards face "Brown Discount". Differential: 15-25% of exit multiple.
SFDR 2.0 Compliance
New product categories with minimum quotas and binding exclusion criteria from 2027. Impact funds need demonstrable intentionality, measurability, and outcome reporting, no self-assessments.
The €9,000 is not a compliance cost, it's systematic risk assessment against material value losses. Compared to failed due diligence (legal costs, burned LP trust, exit discount), this amount is negligible.
Data Reality: What ESG Data a Series A Startup Can Actually Deliver
Regulation calls for audit-ready, ESRS-grade sustainability data. But a Series A startup is an SME: if it reports at all, it does so on the voluntary VSME standard, not full ESRS. Expecting audit-proof ESRS-grade data in due diligence means assessing against a reality the company cannot meet, producing friction instead of insight.
How I bridge the gap
I reconcile what is materially needed for the IC decision with what the startup can actually provide under VSME. The gap between the two is not a footnote, it is part of the risk memo: which data points are missing, which are reliable, and where that turns into real post-investment risk. You get an assessment matched to the target's stage, not a checklist no early-stage company could ever satisfy.
The Financial Business Case: €9,000 as Strategic Risk Assessment
The question is not whether you can afford ESG due diligence, but whether you can afford material adverse impacts you overlooked.
| Sustainability Risk Category | Material Financial Impact |
|---|---|
| Transition Climate Risks | Technologies or business models that become worthless through new regulation (CO₂ pricing, EU ETS 2, EUDR). Early detection avoids stranded assets and secures investment. |
| Physical Climate Risks | Extreme weather events can damage production sites, infrastructure, or supply chains. Climate risk screening per TCFD identifies exposure and adaptation needs. |
| Reputational Risk | A single scandal (working conditions, greenwashing, data protection) can destroy a consumer startup's brand overnight and make follow-on financing impossible. |
| Green Premium / Brown Discount | Studies consistently show: ESG-mature companies achieve "Green Premium" at exits, while ESG laggards face "Brown Discount". Differential: 15-25% of exit multiple. |
The asymmetry is clear: €9,000 fixed price for systematic risk assessment vs. potential million-dollar losses from adverse impacts that remain undetected.
Service Components: Double Materiality Assessment per SFDR Standards
Data in data rooms is often "greenwishing". Material risks hide in corporate culture, missing processes, and what's not documented. That's why I rely on third-party verification and stakeholder interviews instead of automated questionnaires.
Materiality Analysis
Environmental Criteria
Analysis of GHG emissions (Scope 1-3), Scope 3 transparency, GHG intensity, share of renewable/non-renewable energy, activities affecting biodiversity-sensitive areas, water emissions, management of hazardous waste. Particularly critical: Externally verified LCAs for avoided emissions.
Social Criteria
Violations of UN Global Compact principles, missing compliance mechanisms, unadjusted gender pay gap, gender diversity on boards, workplace accident prevention policies, employee retention (>30% p.a. attrition is a warning signal), labor rights in supply chain.
Governance Criteria
IP ownership (who really owns the code?), board independence, whistleblower systems, anti-corruption policies, data protection compliance (GDPR), tax compliance, antitrust compliance. Unclear IP rights have killed deals at the last minute.
Climate Risk Screening (TCFD-compliant)
I distinguish between material risk categories per TCFD framework:
Physical Risks: Is the server location or production facility threatened by extreme climate events (floods, heat, drought)? Climate risk assessment is increasingly part of site evaluations and insurability.
Transition Risks: Will the business model become unprofitable through CO₂ pricing, regulation, or market shifts? A delivery service with purely combustion engines carries massive transition risk, as does a SaaS startup with massive cloud footprint without decarbonization strategy.
Interviews with Key Stakeholders (3-5 persons)
Material adverse impacts only become visible in direct conversation. If the CTO has no idea about information security, the HR head dismisses diversity as "unnecessary", or the supply chain manager has no transparency on raw material sourcing, these are the warning signals no automated ESG score captures. My approach uncovers the discrepancy between pitch deck and reality.
Typical interview partners: Founder/CEO, CTO/Head of Product, CFO/Finance Lead, Head of Operations/Supply Chain, HR/People Lead. Duration: 45-60 min per person, structured per materiality assessment framework.
DNSH Criteria: These Warning Signals I Systematically Identify
These Do No Significant Harm thresholds are systematically reviewed, and often only become visible in interviews with key stakeholders.
Governance Warning Signals
- Unclear IP ownership without transfer agreements
- Missing board independence or advisory board
- Missing GDPR compliance structure
- No whistleblower systems
- Missing anti-corruption policies for emerging market activities
- Missing separation of corporate/personal assets for founders
Social Warning Signals
- Tech team attrition >30% p.a.
- False self-employment risk with freelancers
- Violations of UN Global Compact principles
- Missing workplace accident prevention policies
- Unadjusted gender pay gap >15%
- Missing labor rights compliance in supply chain
Environmental Warning Signals
- Generated GHG emissions higher than leading incumbent solutions (without externally verified LCA)
- Greenwashing in marketing without certificates/LCA
- No Scope 3 transparency despite significant supply chain
- Activities negatively affecting biodiversity-sensitive areas
- High volumes of hazardous waste without proper disposal plan
- Raw materials from conflict regions without transparency/due diligence
Important: These DNSH thresholds only become visible in direct dialogue with key stakeholders. If the CTO has no idea about information security, HR leadership dismisses diversity as a "luxury problem", or the supply chain manager has no transparency on raw material sourcing, these are material adverse impacts no questionnaire captures.

Who Is This Service For?
Venture Capital Funds
Article 8/9 funds requiring audit-proof data for LP reporting from 2027 under SFDR 2.0. Growth-stage VCs understanding material sustainability risks as investment criteria. Corporate VCs with parent company ESG standards. Funds before fundraising (track record in ESG integration required).
Series A+ Startups
Companies in active financing phase wanting ESG differentiation. Startups before M&A processes anticipating buyer due diligence. B2B companies facing ESG requirements from corporate customers (supplier assessments). ClimateTech/Impact startups pitching to Article 9 funds.
Family Offices & Strategic Buyers
Investors not wanting to discover material adverse impacts after contract signing. Strategic buyers needing to minimize post-merger integration costs. M&A teams requiring external confirmation for internal investment committees.
Senior Expertise Instead of Big 4 Junior Consultants
While large consultancies send junior consultants with checklists, I offer senior expertise with judgment for early-stage realities. I understand: A Series A startup can't have the compliance processes of a DAX company, but the materiality analysis must be robust and DNSH thresholds must be respected.
VC Experience: I speak the language of Investment Committees. My memos are tailored to VC decision logic, not corporate compliance theater. Direct access to me, no rotating junior teams, no overhead for global Big 4 structures.
VC & Angel Investor Myself: I invest as a business angel in early-stage startups myself, across a diversified portfolio, in syndicates and alongside specialised climate VCs. I know the dynamics between founders and investors from both sides of the term sheet, and I carry portfolio risk myself. That is the perspective that flows into every due diligence.

FAQ, ESG Due Diligence for VCs & Startups
What is a Sustainability Risk and why is systematic ESG due diligence necessary?
A Sustainability Risk is an environmental, social, or governance event that, if it occurs, can have a material adverse impact on the value of an investment. SFDR 2.0 tightens disclosure requirements from 2027 with binding minimum quotas and exclusion criteria. VCs without audit-proof data risk BaFin intervention. Exit buyers price material ESG risks hard into valuations or treat them as exclusion criteria.
What distinguishes this service from automated ESG assessment tools?
Automated tools send questionnaires and generate scores, I conduct interviews with key stakeholders and materiality analyses. Data in data rooms is often "greenwishing". Material adverse impacts (IP uncertainties, tech team attrition >30%, greenwashing without externally verified LCAs) only become visible in direct dialogue. I deliver a decision-ready memo for the Investment Committee with reasoned risk assessment, not a generic ESG score without context.
Which DNSH criteria do you systematically review?
Climate: Generated GHG emissions higher than leading incumbent solutions, no externally verified LCAs for avoided emissions. Biodiversity: Activities negatively affecting biodiversity-sensitive areas without mitigation measures. Water: Water emissions, extreme water risk exposure without efficiency measures. Circular Economy: High volumes of hazardous waste without proper disposal plan. Social & Governance: Violations of UN Global Compact principles, missing compliance mechanisms, unclear IP ownership. These DNSH thresholds are aligned with SFDR PAI indicators and EU Taxonomy criteria.
What is SFDR 2.0 and why is it relevant for VCs?
The EU Commission proposed SFDR 2.0 in November 2025: The previous Article 6/8/9 categories will be replaced by new product labels (e.g. "Transition", "Sustainable") with binding minimum quotas (approx. 2/3 to 3/4 of portfolio) and binding exclusion criteria for fossil activities. Impact investing receives an explicit definition for the first time with requirements for intentionality, measurability, and outcome reporting. Implementation: around 2027/2028. VCs need audit-proof portfolio data for LP reporting and BaFin compliance.
How is the price of €9,000 justified?
The asymmetry is clear: €9,000 for systematic risk assessment vs. potential million-dollar losses from material adverse impacts. Studies show: ESG-mature companies achieve "Green Premium" at exits (15-25%), while ESG laggards face "Brown Discount". Post-transaction integration of undiscovered sustainability risks costs 10x preventive due diligence. Failed due diligence causes legal costs, burned LP trust, and exit discount. The €9,000 is systematic capital protection.
How does the 4-5 week process work?
Week 1 (Initial Review): Kickoff, data access, document review against exclusion criteria, interview coordination. Week 2-3 (Due Diligence): Interviews with key stakeholders (3-5 persons), double materiality assessment, climate risk screening per TCFD, DNSH threshold review. Week 4 (Results): Consolidation, IC memo draft, materiality matrix, risk assessment. Week 5 (Handover): Final review, presentation, handover of decision-ready document with external confirmation. Express service in 2-3 weeks available (+€6,000).
What is included in the Investment Committee memo?
Executive summary for decision-makers (1 page), materiality matrix (Financial vs. Impact Materiality), detailed results by E-S-G with PAI indicators as supporting evidence, DNSH threshold assessment, mitigation recommendations with prioritization, Go/No-Go recommendation with reasoned risk assessment, SFDR 2.0 mapping to new product categories. The memo is decision-ready with external confirmation, no self-assessment documents.
For which types of VCs is this service suitable?
Article 8/9 funds requiring audit-proof data for LP reporting and BaFin compliance. Growth-stage VCs understanding material sustainability risks as investment criteria. Corporate VCs needing to apply parent company ESG standards to investments. Family offices and strategic buyers not wanting to discover material adverse impacts after contract signing. Funds before capital raising needing to demonstrate track record in ESG integration.
Why senior expertise instead of Big 4?
Big 4 send junior consultants with checklists, I offer senior expertise with judgment for early-stage realities. I understand: A Series A startup can't have the compliance processes of a DAX company, but the materiality analysis must be robust and DNSH thresholds must be respected. My memos are tailored to VC decision logic, not corporate compliance theater. Direct access, no rotating teams, no overhead for global structures.
Which startups should use this service?
Series A+ companies in active financing phase wanting ESG differentiation. Startups before M&A processes anticipating buyer due diligence. B2B companies facing ESG requirements from corporate customers (supplier assessments). ClimateTech/Impact startups pitching to Article 9 funds and requiring external confirmation for avoided emissions claims.
