About Fiegenbaum Solutions

 

Fiegenbaum Solutions has been around since 2014.

What shapes my work is a simple conviction: real partnership beats off-the-shelf solutions. I take the time to understand the details before developing solutions – so the outcome is more than a report that gathers dust.

Whether you are a start-up just getting going or an established mid-market company exploring new growth areas, the process stays the same: listen, understand, strategise, implement. That is how measurable results emerge instead of compliance on paper.

My focus areas – Climate risk, VSME reporting, carbon accounting & ESG due diligence – are listed with fixed prices on the pricing overview →

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.

 

Why Work With Me?

There's no shortage of sustainability consultants out there. So what sets me apart?

Beyond a strong track record, here's what I bring to the table:

  • Own software: VSMEasy for VSME reports, MULTIPLYE for carbon accounting – not theory, used daily in my own practice

  • 300+ projects since 2014 – from start-ups to international corporations, across 20+ markets

  • Venture Partner at Climate Insiders – access to early-stage ClimateTech and a candid view on which ESG promises hold up

  • Academic roots in data structures (University of Tübingen) – which is why complex CSRD data models do not faze me

  • Direct with the senior consultant – no junior-team detours, no escalation ladder

  • Transparency - my consulting is transparent. You always know what I am working on and why.

  • Openness - if a project will not deliver real value for you, I say so – even when that runs against my own interest.

  • Experience - more than 300 projects across 20+ markets since 2014 – in start-ups, SMEs and international corporations. That experience feeds into every strategy.

  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)

€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.
