Climate risk and ESG data, turned into decisions

Mid-market companies in transition

For companies that want to know which sites are exposed to climate risk, which investment comes first and whether their data holds up to bank and customer requests. Without an in-house sustainability team.

Investors & VCs

For investors who want to identify material ESG risks before the investment, ready for the investment committee in 4 to 5 weeks, without slowing down the deal.

Public sector

For state-owned companies, municipalities and public authorities that need a traceable assessment of climate risk to their properties and facilities.

“As a mid-sized company, we faced the challenge of systematically capturing climate risks without building a dedicated department. The analysis not only gave us regulatory certainty but enabled concrete investment decisions, for example which sites to equip with PV canopies first.”

Arndt Kammerer

Authorised Officer, Corporate Development
Hahn Automobile GmbH + Co. KG

“So that we could also communicate what we have achieved, and the measures still to come, to our stakeholders, Mr Fiegenbaum supported us in preparing our voluntary sustainability report based on the EU standard (VSME). […] This kept the effort on our side manageable […].”

Managing Director
Smart Press Shop GmbH & Co. KG

“Johannes brings the ESG view into our deal reviews: which sustainability risks are material for an early-stage climate startup, and which are not yet.”
