About Fiegenbaum Solutions

 

I founded Fiegenbaum Solutions in 2014 and have spent the years since advising clients across industries on sustainability strategy and compliance.

My approach is simple: true partnership. Every organisation is different, with its own challenges and goals. I take the time to understand the details before developing tailored solutions that actually fit.

This close collaboration builds the trust and insight needed to deliver real results – not just reports that gather dust.

Whether you're a start-up just getting started or an established company exploring new opportunities, my process stays the same: listen, understand, strategise, implement. That's how I help clients achieve lasting success.

How I Can Help

I help clients reduce costs and manage risk through:

  • ESG & Sustainability Strategy: Tailored strategies that connect environmental goals with concrete business requirements – from materiality assessment and stakeholder engagement through to an actionable ESG roadmap. Experience across more than 300 projects consistently shows the same pattern: sustainability delivers results when it is embedded in the business model, not bolted on alongside it.
    → Double Materiality Analysis – The foundation of any serious ESG strategy
    → Scope 3 Quick Check – Assess your indirect emissions in 5 minutes

  • VSME Reporting for SMEs: Following the EU Omnibus changes, the VSME standard is now the relevant framework for most SMEs. I guide you through the entire process – from module selection and data collection to the finished report. Where appropriate, I use VSMEasy, a workflow-oriented tool that keeps the process structured and manageable.
    → VSME Readiness Check – Understand where you stand today

  • Compliance & Reporting: Regulations such as CSRD, EU Taxonomy, EUDR, CSDDD, and CBAM create obligations that surface well before any audit – in financing conversations, supplier requests, and procurement processes. I help you understand what is actually required, prioritise accordingly, and implement in time.
    → CSRD Materiality Screening – Identify your material sustainability topics
    → CSRD Report 2026 – Contents, deadlines, and implementation

  • Climate Risk Analysis: Physical and transition risks are now part of credit assessments, due diligence processes, and CSRD-compliant reporting. I analyse which risks are material to your business model – and what they mean operationally and financially.
    → Climate Risk Analysis for Companies – Methodology, scope, and how to get started
    → CSRD Climate Risk Quick Check – A first assessment in minutes

  • ESG Due Diligence for VCs & Startups: For venture capital funds, I provide structured ESG due diligence as a basis for investment decisions, Article 8/9 positioning, and LP reporting. For startups from Series A onwards, I develop the ESG foundation that investors now expect: impact measurement, risk assessment, and scalable processes.
    → ESG Due Diligence for VCs – Framework and scope of services
    → ESG Investment Quick Check – Initial assessment of ESG performance

  • CO₂ Accounting & Impact Modelling: For pre-seed and seed-stage startups and VC/PE funds, I provide CO₂e impact calculations and risk analyses – as the basis for a credible impact narrative and robust investor communication.
    → Company Carbon Footprint – Methods, tools, and best practices
    → Product Carbon Footprint & LCA – Measuring product-level climate impact

  Scope 3

Advising others on sustainability reporting means knowing your own numbers. I track my company's emissions monthly – automatically captured from business accounts and categorised by emissions source.

Total emissions 2024: 1.77 t CO₂e

  • Software & IT Services — 420 kg (24%)
  • Office & Infrastructure — 369 kg (21%)
  • Marketing & Digital Advertising — 278 kg (16%)
  • Mobility & Transport — 195 kg (11%)
  • External Services & Other — 505 kg (28%)

Monetising the emissions (1.77 t CO₂e)

UBA Social Cost
€420/year
EU ETS Market Price
€150/year
Premium Offsetting
€212/year

Basis: UBA €237/t (social cost of carbon), EU ETS €85/t (current market price), offsetting €120/t (min. BBB-rated projects)

Methodology & System Boundaries

This report covers Scope 3 emissions from software licences, marketing, financial services, and office infrastructure. As a sole trader operating from a home office, there are no Scope 1 emissions. Scope 2 is zero, with 100% renewable electricity throughout. All business travel is fossil-free – rail, public transport, and bicycle only. Cloud infrastructure was fully consolidated to Google Cloud (carbon neutral) in 2024.

The aim is a documented, year-on-year reduction – not offsetting before reduction potential has been exhausted.

Career Timeline

A Bit More About Me

My introduction to data came earlier than expected. As a research assistant at the University of Tübingen from 2007, I worked on linguistic data structures – a field that now underpins the large language models everyone is talking about. At the time, nobody quite knew where it was heading.

After university, I moved into practice: first at TBG Digital in London, then at Sprinklr in Hamburg. Both roles taught me how data, technology, and decision-making connect inside organisations – and where they fail to, despite the obvious need.

In 2014, I founded Fiegenbaum Solutions, initially with a broad remit. Over time, the focus has sharpened considerably: ESG strategy, sustainability reporting, and climate risk management – with a particular emphasis on the mid-market, startups, and venture capital. Today I help companies navigate frameworks such as CSRD, VSME, EU Taxonomy, and EUDR, and find ways to turn compliance obligations into strategic positions.

In 2020, I co-founded MULTIPLYE, a carbon accounting tool that I continue to use in my own business. Having built and operated such a system myself gives me a clear-eyed view of where emissions data collection works in practice – and where it quietly breaks down.

Since 2023, I have been a Venture Partner at Climate Insiders, an investor community focused on climate deeptech. The role keeps me close to early-stage technologies and business models, and sharpens my judgement about which ESG commitments are substantive and which are not.

Outside work: sport, tea, family – in varying order.
